Clean Aviation SWITCH Project to Advance Hybrid-Electric and Water Enhanced Turbofan Technologies

This will be the hybrid aircraft engine of the future.

Airbus has confirmed that it will work with France, Germany, and Spain to build the Future Combat Air System (FCAS).

With the help of the European Union Clean Aviation Joint Undertaking, a collection of aerospace technology companies has announced the creation of a cooperative collaboration to create hybrid-electric and water-enhanced turbofan technology for future aircraft propulsion systems (Clean Aviation).

By comparing these technologies to current state-of-the-art propulsion systems for short- and medium-range aircraft, MTU Aero Engines AG (MTU), Pratt & Whitney, Collins Aerospace (Collins), GKN Aerospace, Airbus, and others hope to show how these technologies can increase fuel efficiency and reduce aircraft CO2 emissions by up to 25%. MTU manages the consortium’s operations.

The Sustainable Water-Injecting Turbofan Comprising Hybrid-Electrics (SWITCH) project is focused on developing a novel propulsion concept built from two revolutionary and synergetic technologies: Water Enhanced Turbofan (WET) and hybrid-electric propulsion. By combining these technologies with Pratt & Whitney’s GTFTM engine architecture, the SWITCH concept aims to significantly enhance efficiency and substantially reduce emissions across the full operating envelope of an aircraft.

The hybrid-electric GTF powertrain will enable even greater efficiency across all phases of flight by leveraging highly efficient megawatt class electric motor generators, power electronics, and batteries to optimize the performance of the fuel-burning gas turbine. The WET concept recovers water vapor from the engine exhaust and re-injects it into the combustion chamber to significantly improve fuel efficiency, reduce NOx emissions, and lessen contrail forming emissions.

Current funding for Phase 1 of SWITCH extends to 2025 and will include testing of a hybrid-electric GTF engine, WET technology and sub-system laboratory testing, and design activity around an integrated hybrid-electric and WET cycle propulsion system. Subject to successful testing of these key technologies and component designs, further phases of ground testing and flight tests are expected to follow.

Clean Aviation is a public-private partnership co-funded by the European Union between the European Commission, the aerospace industry, and research institutes, dedicated to advancing transformational aircraft technologies which will help enable net zero emissions for aviation by 2050. The project will be supported by UK Research and Innovation, and will leverage collaboration between multiple aerospace companies, universities and research organizations across 11 countries in Europe and the United States.

Which is bigger 777x or 787 aircraft ?

Which is bigger 777x or 787 aircraft ?

The 777X is a new series of the Boeing 777 family and is designed to be larger and more efficient than its predecessor. It features two variants: the 777-8 and the 777-9, being the larger of the two.

The Boeing 777X emerges as the larger sibling within the Boeing family, representing a significant leap forward in both size and efficiency. Comprising two variants, the 777-8 and the 777-9, the latter takes the crown as the larger of the two. With its expansive fuselage and impressive wingspan, the 777X is tailored for long-range journeys and boasts a substantial passenger capacity.

On the other hand, the Boeing 787, affectionately known as the Dreamliner, occupies a niche in the market as a smaller yet formidable aircraft designed for medium to long-range flights. Its distinguishing feature lies in its composite fuselage, a technological marvel that renders it lighter and more fuel-efficient compared to conventional aluminum counterparts. The Boeing 777X is larger than the Boeing 787 aircraft.

When it comes to passenger capacity, the 777-9 reigns supreme, typically accommodating a sizeable contingent of 400-425 passengers in its standard configuration. In contrast, the 787, with its more modest dimensions, typically carries between 240-290 passengers, depending on the variant and layout.

One of the remarkable innovations introduced with the 777X is its folding wingtips, a feature designed to address the logistical challenges of accommodating such a large aircraft in conventional airport gates. These folding wingtips enable the 777X to retract its wings, allowing it to fit into gates designed for smaller aircraft while still reaping the benefits of an extended wingspan during flight, thereby enhancing fuel efficiency and operational flexibility

China Secures Production Certificate for Mass Production of Pilotless eVTOL Aircraft

China Secures Production Certificate for Mass Production of Pilotless eVTOL Aircraft
EHang

The first passenger-carrying pilotless electric vertical takeoff and landing (eVTOL) aircraft in the world, the EH216-S, has received the Production Certificate for its eVTOL aircraft from the Civil Aviation Administration of China (CAAC).

This is a significant milestone for EHang Holdings Limited, the leading UAM technology platform company in the world. This outstanding accomplishment is another big step towards mass manufacturing for the eVTOL aircraft and the ensuing commercial operations, building on the ground-breaking acquisition of the Type Certificate and the Standard Airworthiness Certificate for the EH216-S.

The PC is a crucial certificate that the aircraft maker receives from the CAAC, the country’s aviation authority. By obtaining this certificate, EHang has demonstrated that it has set up a quality management system for mass production that satisfies the airworthiness regulation standards set forth by the CAAC, and the company has been given permission to continue producing mass quantities.

It is also a strong guarantee of the calibre of the goods made by EHang. Raw materials, supplier management, manufacturing organisation, production quality control, aircraft pre-delivery test, after-sales repair and maintenance, etc. are all included in the mass production quality management system for the EH216-S.

To ensure that every aircraft and its components that roll off the production line strictly adhere to the approved type design and safety requirements, the system sets clear guidelines and documentation for every step in the production procedure. This ensures comprehensive traceability and safety control.

Four Airbus A380 Superjumbos lined up to be scrapped

EASA Proposes AD for Airbus A380 Wing Rib Foot Cracks

In a strategic move aimed at reclaiming valuable resources from the iconic Airbus A380 aircraft, VAS Aero Services and Dr. Peters Group have announced a significant collaboration.

This partnership marks a milestone in aviation logistics and aftermarket services, with four of these colossal planes slated for teardown and redistribution of used serviceable material (USM).

The venture between VAS Aero Services, renowned for its expertise in aircraft dismantlement, and Dr. Peters Group, a prominent Germany-based investment fund management firm, underscores a commitment to sustainable aviation practices. This isn’t their first foray into scrapping A380s; their successful partnership has already seen the dismantlement of these aircraft, making them pioneers in this niche.

Under the agreement, the latest consignment brings the tally to eight A380s entrusted to VAS by Dr. Peters Group. Managing Director Christian Mailly of Dr. Peters Group emphasized the trust placed in VAS, citing their unparalleled capabilities in dismantlement and aftermarket sales network. It’s a strategic move in response to the growing demand for quality USM parts, particularly with the resurgence in reliance on the A380.

Notably, the teardown process will be carried out at various locations, optimizing the positioning of harvested parts to cater to different markets. While some parts will be positioned in Europe to support operators in the region and the Middle East, others will remain in the Asia-Pacific region. This meticulous strategy ensures efficient access to spare parts, benefiting MROs and airlines across these markets.

The decision to retire these A380s comes at a time when operators are reassessing fleet strategies amidst evolving market dynamics. Despite initial plans for quick retirement due to the emergence of more fuel-efficient alternatives, factors such as a rebound in long-haul demand and delays in new widebody deliveries have prompted operators to reconsider. The A380, with its unique capacity and capabilities, presents a practical solution for short-term capacity management.
