Silent flight edges closer to take off, according to new research.

The mystery of how futuristic aircraft-embedded engines, featuring an energy-conserving arrangement, make noise has been solved by researchers at the University of Bristol.

The study, published today in Journal of Fluid Mechanics, reveals for the first time how noise is generated and propagated from these engines, technically known as boundary layer ingesting (BLI) ducted fans. BLI ducted fans are similar to the large engines found in modern airplanes but are partially embedded into the plane's main body instead of under the wings.

As they ingest air from both the front and from the surface of the airframe, they don't have to work as hard to move the plane, so it burns less fuel.

The research, led by Dr Feroz Ahmed from Bristol’s School of Civil, Aerospace and Design Engineering under the supervision of Professor Mahdi Azarpeyvand, utilised the University National Aeroacoustic Wind Tunnel Facility. They were able to identify distinct noise sources originating from the duct, the rotating fan, and the air flowing over the curved airframe surface.

They found that the noise pattern changes depending on how much thrust the fan is producing. When the fan is producing high thrust, they observed a noise pattern similar to what is seen in fans without ducts. But when the fan is producing less thrust, the noise pattern changes because the duct itself starts making more noise.

Dr Ahmed explained: “Our study addresses this urgent issue of noise, which poses a major obstacle in obtaining certifications, by uncovering the physics behind the noise these configurations produce.

“By understanding the noise mechanisms in BLI ducted fans, it is hoped that industrial guidelines can be developed for quieter airframe-integrated propulsion systems in future aircraft concepts, from large-scale conventional aircraft to small-scale electric vertical take-off and landing, known as eVTOL, aircraft.”

Projects such as the Bell X-22A, Embraer X, Airbus E-fan, Lilium Jet, Green Jet, and Hybrid Air Vehicle are leading the way in developing these systems for next-generation aircraft. They are becoming more popular due to advancements in powerful electric motors. 

Aviation net zero roadmaps comparative review

IATA - The International Air Transport Association along with the Air Transportation Systems Laboratory at University College London (UCL), the Air Transport Action Group (ATAG), the International Council on Clean Transportation (ICCT) and the Mission Possible Partnership (MPP), released the Aviation Net Zero CO2 Transition Pathways Comparative Review. 

This is the first publication to compare 14 leading net zero CO2 transition roadmaps for aviation. The report aims to provide a “one-stop shop” for airlines, policymakers and all aviation stakeholders to better understand the key similarities and differences between the various roadmaps, and their visions for achieving net zero carbon emissions for aviation by 2050. Specifically, the report compares the selected roadmaps in terms of their scope, key input assumptions, modelled aviation energy demand, respective CO2 emissions, and the emissions reduction potential of each mitigation lever (new aircraft technologies, zero-carbon fuels, SAF, and operational improvements).

Key findings from this analysis include:

•    Possible pathways to net zero CO2 emissions by 2050 differ significantly depending on the key assumptions of the authors regarding how decarbonization technologies and solutions may evolve. Depending on these assumptions, the resulting role of particular levers in aviation’s decarbonization will be more or less important.  

•    All roadmaps assume that Sustainable Aviation Fuels (SAF) will be responsible for the greatest amount of CO2 reductions by 2050. The role of SAF varies from 24%-70% (with a median value of 53%). This wide range reflects the uncertainties regarding potential supportive government action, the level of investments, cost of production, and profit potential, as well as access to feedstocks.  

Disinformation actors spreading 1.5bilion fake news posts each day....

• Facebook users create the highest level of daily disinformation posts (1 billion posts)
• X has the highest proportion of disinformation actors (8.7% of all active users) 
• LinkedIn has the most rampant disinformation actors (each creating 6.6 posts per day) 
• Instagram and YouTube produce the least amount of daily disinformation 
• 
  

ID Crypt Global has analysed data from Code of Practice on Disinformation report from TrustLab to understand the rate at which disinformation is being spread through the six main social media platforms - Instagram, Facebook, X, LinkedIn, TikTok, and YouTube - before conducting its own analysis estimating how many disinformation posts are being created each day, and which platforms are most responsible for the spread of fake news and media. 

The most recent available data* estimates that there are an estimated total of 10.5 billion social media users across the six main platforms.

Facebook boasts the most users with 3 billion people logging onto the platform each month. Facebook is followed by YouTube (2.5bn), Instagram (2bn), TikTok (1.5bn), LinkedIn (771m), and X (619m). 

1.5bn fake news posts created or shared every day on social media

Across all platforms, it is estimated that 5% of users are disinformation actors, which means all in all, there are 516 million users actively spreading fake news and media. 

It is estimated that each disinformation actor creates an average of 3.9 posts per day, meaning that across all platforms, 1.5 billion pieces of disinformation are created or shared every single day. 

Facebook and X host highest volume of disinformation content

ID Crypt’s research reveals that Facebook creates the most pieces of fake news. 

It is estimated that disinformation actors account for 7.8% of all of the platform’s users and that each of them creates an average of 4.3 daily posts. This means Facebook alone is responsible for over one billion fake news posts every single day. 

When it comes to the highest proportion of users being disinformation actors, X is the worst platform.  

8.7% of all X users are disinformation actors and each of them is creating 3.8 daily posts. This means the hugely influential platform is spreading 205 million fake news posts every single day. 

Nine Airline companies comprise a $30 billion club courtesy of co-branded credit cards

CarTrawler-sponsored research explores the jumbo economics of loyalty programs at Air Canada, Alaska, American, Delta, IAG, JetBlue, Qantas, Southwest, and United.

Co-branded credit cards deliver wheelbarrows of money for some airlines. The latest IdeaWorksCompany report explores how this has transformed frequent flyer programs (FFPs) and contemplates the effect upon customer loyalty. Many airlines have shifted from sole reliance on behavioural loyalty, which relies upon a customer’s expectations for service and quality. Carriers now embrace transactional loyalty which emphasizes exchange relationships where something is given and something is received. The report advises caution about over-reliance on the co-branding bounty and suggests focusing more on the overall customer experience.

Airline Loyalty Becomes a Billion Dollar Club was issued today as a 16-page report. It describes how airline FFPs generate revenue in the billions and provides abundant analysis and research on the business of co-branded credit cards:

 Delta Air Lines, with 7.5 million SkyMiles credit cards, saw payments from American 

Express jump by 24% to $6.8 billion for 2023.

 IAG (British Airways and Iberia), navigated Europe’s prevalent merchant fee 

restrictions and achieved outstanding Avios partner revenue of £1 billion.

 Southwest generated more than 22% of its 2023 total revenue from its Rapid 

Rewards program and Chase-issued credit card.

 Qantas achieved a revenue result of $96 per Frequent Flyer Program member with 

help from nearly 40 credit card options available to consumers in Australia.

Aileen McCormack, Chief Commercial Officer at CarTrawler commented on the report, “In today's aviation landscape, airlines are vying for price-conscious customers by providing greater rewards for their loyalty. The rise of ‘transactional loyalty’ - where passengers seek more incentives in exchange for their regular custom - has seen huge growth of frequent flyer programmes and co-branded credit cards, which have generated an incredible $30 billion in revenue for a selection of early adopting airlines. 

We understand that customers are seeking additional ways to spend their miles to gain value. This is why CarTrawler works with the world’s leading airlines to enhance their loyalty programmes by offering bespoke car rental earn & redeem functionality down to tier membership status and even fare class."

Single use plastics products report released.

The International Air Transport Association (IATA) released the Reassessing Single Use Plastics Products in the Airline Sector report to assist airlines, regulators, and the airline supply chain to mitigate the environmental impacts of single-use plastic products (SUPP). 

This publication is timely as the United National Environmental Program (UNEP) has convened an intergovernmental negotiating committee (INC) to develop an international legally binding agreement on SUPP use by the end of 2024. 

SUPP are widely used in aviation due to their strength, lightness, and ability to meet safety and security regulations. However, the airline sector faces challenges associated with improved cabin waste performance and the replacement of SUPP with sustainable alternatives. In addition, airlines face technical and operational obstacles, and the lack of harmonized and risk-based regulations presents a significant barrier to improving recycling and circularity of waste management. The absence of smart regulation continues to constrain airline efforts to improve the sustainability of cabin operations.

Collaboration across the aviation value chain is vital to enable the adoption of circular economy principles and to facilitate the reduction and replacement of SUPP that is necessary for reducing waste and increasing material recovery.

The report advocates for a sectoral approach to managing SUPP in aviation with a clear set of recommendations. Key recommendations include:

For airlines:

•    Reduce waste at source by reviewing standards and procedures through the lens of waste reduction and reuse, and professionally assess the need for SUPP. Set clear targets for the elimination, measurement, and tracking implementation, and disclose progress.

•    Introduce reusable items as a strategy to drive circularity. This requires logistical changes that incorporate a closed-loop service, including the impact of potential added weight of reusables on aircraft on fuel burn and carbon emissions.

•    Improve waste management and recovery by facilitating onboard and ground waste segregation, and undertaking waste composition audits for passenger and cargo operations.

For regulators:

The UK Civil Aviation Authority is to launch an independent review into the technical issue NATS faced on Monday 28 August

The UK Civil Aviation Authority is to launch an independent review into the technical issue NATS faced on Monday 28 August that saw hundreds of flights delayed and cancelled.   

NATS’ preliminary technical report sets out the causes of the issue and actions taken to rectify and mitigate the effects. It found the incident occurred due to an anomaly that forced the system to stop processing flight plans. The system was closed to maintain safety and required manual operation to continue service.

The UK Civil Aviation Authority will now independently review the wider issues around the system failure and how NATS responded to the incident.

If there is evidence that suggests NATS may have breached its statutory and licensing obligations, the UK Civil Aviation Authority will take any appropriate steps.

The review will also set out lessons to be learned for the future for the benefit of consumers and the industry.

Rob Bishton, Joint-Interim Chief Executive at the UK Civil Aviation Authority, said:  “Millions of passengers every year rely on air traffic control to work smoothly and safely.  The initial report by NATS raises several important questions and as the regulator we want to make sure these are answered for passengers and industry.

If there is evidence to suggest NATS may have breached its statutory and licensing obligations we will consider whether any further action is necessary.”

The scale of the disruption that followed was significant and meant some passengers faced long delays, in some cases, waiting several days for alternative flights. 

Airlines worked around the clock, putting on extra capacity to resolve the issue. Airlines have obligations to look after their passengers in these circumstances and bring them home as soon as possible. 

NATS shared its preliminary technical report on the failure with the UK Civil Aviation Authority on Monday (4 September) and the regulator sent it to the Secretary of State for Transport, Mark Harper and Aviation Minister, Baroness Vere outlining its next steps.

Details of the independent review will be published by the end of September 2023.

Transport Secretary Mark Harper said: "I welcome NATS’ preliminary report outlining the facts of last week’s air traffic control technical failure – particularly the confirmation that there were no safety issues as a result.

I also welcome the announcement from the Civil Aviation Authority (CAA) of an independent review to dig deeper into this event and understand whether there are any further steps to be taken to improve the resilience of the air traffic control system.

Thousands of passengers faced disruption as a result of the failure, with over 1500 flights cancelled and hundreds more delayed. I once again want to echo NATS’s apology to those who were caught up in it, with a technical fix now identified to ensure that such an incident does not recur."

Propellers are louder over ground new research finds.

The effects of the ground on propeller noise have been measured experimentally for the very first time by researchers in the Aeroacoustics research team at the University of Bristol.

In findings, published in the Journal of Sound and Vibration, the team found clear differences in the noise characteristics of propellers when over ground, known as ‘Ground Effect’, compared to when operated normally. They noted an overall noise increase when measuring at angles above the ground, with hydrodynamic and acoustic interaction effects being a key factor to the overall noise trends.

It is hoped this research, which was sponsored by Embraer S.A, and tested in the National Aeroacoustic Wind Tunnel facility, can inform strategies to reduce the noise of aircraft while taking off or landing, by either changing the design of the landing pads or by changing the design of proposed aircraft architectures.

Lead author Liam Hanson explained: “In light of the need for greener aviation, there has been a push in the aviation industry to develop electrified aircraft.

“There is a lot of potential benefits from electric aircraft which have been identified by a variety of companies worldwide, including all of the major aircraft manufacturers.”

However, if urban air services such as on-demand air taxis are to become a reality within city limits, engineers must tackle the issue of sound pollution, generated by propellers.

The Royal Aeronautical Society launches its Contrails and Contrail Management Briefing Paper

The Royal Aeronautical Society launched its Contrails and Contrail Management Briefing Paper at the Farnborough International Sustainable Skies World Summit last week.

The paper published by the Greener By Design specialist group aims to raise awareness of contrails, defining what they are and the impact they have on aviation’s effective radiative forcing. Currently contrails and contrail cirrus are responsible for half of aviation’s effective radiative forcing.

The implementation of contrail management systems could be achieved in a matter of years, not decades, and it is important that aviation’s stakeholders seize this opportunity now.

The paper provides recommendations for industry, regulators and government to work together to mitigate contrails using methods that can help enable the aviation industry to reach is Net Zero targets by 2050. Contrail management provides an opportunity to radically reduce aviation’s effective radiative forcing, offsetting some, if not all, of the effects of both CO2 and NOx and begin reducing aviation’s climate impact in the very near future.

RAeS CEO David Edwards said: “This Royal Aeronautical Society paper highlights the effects of contrails on the climate and demonstrates that Contrail Management is a critical area of focus in reaching our industry Net Zero targets by 2050. Whilst there is no one solution to making aviation sustainable, all areas such as Sustainable Aviation Fuel, new propulsion power sources and Airspace modernisation need to be all part of the response. The great benefit of Contrail Management is that it can be implemented in a matter of years, contributing to reducing aviation’s climate effect very quickly.

The Society is the only global organisation serving the entire aviation, aerospace, and space communities as both a learned society and a professional engineering institution. As such, the RAeS is independent, evidence-based and authoritative, relying on a body of knowledge going back more than 150 years.

Hydrogen Aircraft Global Market to Reach $2.63 Billion by 2026

The global hydrogen aircraft market is expected to grow from $0.92 billion in 2021 to $1.09 billion in 2022 at a compound annual growth rate (CAGR) of 19.13%. The hydrogen aircraft market is expected to grow to $2.63 billion in 2026 at a compound annual growth rate (CAGR) of 24.60%.

North America was the largest region in the hydrogen aircraft market in 2021. North America is expected to be the fastest-growing region in the forecast period. The regions covered in the hydrogen aircraft market report are Asia-Pacific, Western Europe, Eastern Europe, North America, South America, Middle East and Africa.

An increase in air passenger traffic across the globe is expected to propel the growth of the hydrogen aircraft market. Air passenger traffic refers to scheduled passengers (number of people who have booked a flight with a commercial airline, excluding charter flights) handled by the global airline industry. With the rising number of passengers, more flights are in operation than ever before, leading to pollution due to the emittance of harmful gases by aircraft.

To overcome the problem of pollution, hydrogen-based aircraft comes out to be a clean option. According to the International Air Transport Association (IATA) passenger data for March 2022, total traffic in March 2022 (measured in revenue passenger kilometers or RPKs) was up 76% compared to March 2021. Thus, an increase in aviation will drive the aviation analytics market.

Outlook on the Smart Airport Global Market to 2028 - Featuring Honeywell International, Cisco Systems and Huawei Technologies Among Others

The "Smart Airport Market Forecast to 2028 - COVID-19 Impact and Global Analysis by Component and Application" report has been released. 

The Smart Airport Market size is expected to grow from US$ 26,073.62 million in 2022 to US$ 66,763.46 million by 2028.

The emerging need for cost-effective and efficient systems across airports is one of the major trends in the smart airport market. According to International Air Transport Administration, the airport operational costs can be as high as US$ 9.95 per passenger aeronautical revenue, US$ 7.08 per passenger non-aeronautical revenues, or US$ 13.69 per passenger total cost. The systems deployed for performing airport operations are expensive and incur recurring costs to airports for servicing, upgrading, and maintenance.

The deployment of smart parking in smart airports is one of the major examples of cost-effective airport systems. These systems provide directions to passengers to find available parking spaces. Mobile smart parking apps can also be integrated with e-ticketing for parking to provide a seamless passenger experience and improve operational efficiency and reliability of parking areas, resulting in greater revenue generation at a lower cost for airport administrations.

Impact of COVID-19 Pandemic on Smart Airport Market

Following a decade of a constant and substantial increase in global passenger traffic, the COVID-19 pandemic effectively discontinued activities at airports globally in the second quarter of 2020. As a result, the overall number of passengers in 2020 declined dramatically compared to 2019. The Middle East will continue to be one of the most affected area in terms of relative decline in air passengers, as it registered a drop of 69.3% in 2021.

This is owing to the region's reliance on foreign travel and connectivity, which are rebounding at a considerably slower pace than domestic travel. South America, however, is predicted to recover faster than the other regions in 2021. While major challenges exist, the road to recovery is becoming clear.

For instance, Dubai Airports has worked with Huawei to create a smart airport that provides what consumers want: short lines, simple online services, and on-time flights. The UAE intends to expand Dubai International Airport to handle 120 million people annually by 2023, up from the existing capacity of 90 million. Free Wi-Fi, Smart gates, data gathering and sharing, airport apps, requirement projections, asset management and maintenance, and aircraft punctuality rate monitoring have all been emphasized in these smart airports.

Growing number of airlines are adding more healthy options to in-flight menus

The airline industry is projecting an industry-wide return to profitability in 2023, and full recovery in 2024. Along the way, the world's top airline carriers have been revamping the in-flight experience, most noticeably by adding more meatless options to their menus. "Food is one of the most tangible signals of what an airline thinks of its customers," said former airline executive Henry Harteveldt, founder of travel consulting firm Atmosphere Research Group.   From airport restaurants to in-flight food, eating during travelling is often a puzzle, trying to figure out options that are both affordable and nutritious. When you add dietary restrictions into the mix, it makes it even more difficult. 

Currently, over 9.7 million American identify as vegan, and even more, people are looking to reduce their meat and dairy consumption. Now, many major airlines are introducing healthier plant-based options.  As a result of that is that the In-Flight Catering Services market should continue its growth rate in the coming years. One report from ResearchAndMarkets projects that the global market for In-Flight Catering Services is projected to reach a revised size of US$21.5 Billion by 2024, registering a compounded annual growth rate (CAGR) of 4.6% over the analysis period.  An article in APEX (The Airline Passenger Experience Association) added: "After two-plus years of individually-wrapped snacks and/or no inflight foodservice to speak of, full-service meal options are back and better than ever. Taking a cue from the pandemic-era push towards cleaner, greener living and sustainability, airlines around the globe have been livening up their inflight meal options with a host of sustainable menu items."    Active companies in the markets this week include: Pangea Natural Foods Inc., Alaska Air Group, United Airlines Holdings, Inc., Spirit Airlines, Inc., Delta Air Lines.

Aircraft Communication System Market worth $12.8 billion by 2027

Aircraft Communication System Market is projected to grow from USD 8.2 billion in 2022 to USD 12.8 billion by 2027, at a CAGR of 9.2% from 2022 to 2027, according to a new report by MarketsandMarkets™. The demand for Iris SATCOM and data links such as L-DACS to meet the need of various types of aircraft communications is driven by the rising demand for internet protocol (IP) based broadband. Additionally, it is also anticipated that during the forecast period, the use of commercial off the shelf technology in aircraft communication systems would boost the markets growth globally.

Aviation industry could cut climate impact by 20% in five years

Photo by Josue Isai Ramos Figueroa on Unsplash

The findings of a new paper could provide impetus for the aviation industry to drastically reduce its climate impact with only minimal changes to aircraft equipment and infrastructure.

The University of Bristol paper, published in the journal Aerospace, suggests modification to air traffic control procedures and aircraft operations could reduce the climate impact of aviation by as much as 20 per cent in the next five to 10 years.

Lead author Kieran Tait, who completed the review of the latest aviation emissions science, said: “Aircraft non-CO2 emissions are responsible for over two-thirds of aviation’s net climate impact, yet due to the focus on decarbonisation in policymaking - which is essential to meet net zero targets - mitigation of these emissions is often overlooked.

“Flight route modifications in the form of climate optimal routing, to avoid climate-sensitive regions, and formation flight, in which two aircrafts fly one behind the other (separated by ~2km) could hold the key to drastically reducing aviation's climate impact.”

There are two main contributors to aviation's non-CO2 climate impact – aircraft condensation trails (contrails) and emission of nitrogen oxides (NOx). The warming effect of non-CO2 emissions strongly depends on the chemical and meteorological state of the atmosphere at the instant they are released.

Contrails account for 51 per cent of aviation’s total climate impact. Where the air is very cold and humid, the water vapour in the contrails condenses around particulates to form ice crystals which trap heat and have a net-warming effect. Similarly, emissions of NOx react with chemicals in the atmosphere to generate ozone and reduce methane. However, the generation of ozone tends to outweigh the methane reduction, leading to a net warming effect.

“While climate optimal routing may require a longer flight, and therefore an additional one to two percent fuel burn, avoiding climate-sensitive areas could actually reduce the overall climate impact of a flight by around 20 per cent.
