Airbus UpNext has selected Curtiss-Wright’s Actuation Division to provide custom actuation technology for use on the eXtra performance WING demonstrator project. The Curtiss-Wright project, which will explore active control technologies to improve wing performance, includes an intelligent wing tip, known as a semi-aeroelastic hinge. Under the contract, Curtiss-Wright will provide Airbus UpNext with an actuation system for control of the semi-aeroelastic hinge on the scaled demonstrator aircraft. The demonstrator integrates the eXtra performance WING on a Cessna Citation VII business jet platform. The Curtiss-Wright actuation system features the complete package of systems for enabling the semi-aeroelastic hinge function. The semi-aeroelastic hinge technology enables a more efficient wing design that improves aircraft fuel burn and reduces environmental impact. The demonstrator will improve and optimize wing aerodynamics and performance for future commercial aircraft, regardless of propulsion solution and aircraft configuration.

UK LCC easyJet CEO Johan Lundgren announced a multi-million-pound investment in a new partnership with Rolls-Royce, called H2ZERO, which aims to explore hydrogen propulsion technologies. Rolls-Royce chief technology and strategy officer Grazia Vittadini said the partnership aims to demonstrate that hydrogen has the potential to power aircraft from the mid-2030s onwards, ultimately including narrowbodies. The open-ended cooperation will see the two companies cooperate on a series of early concept ground tests of a Rolls-Royce AE 2100 engine in the UK, which will begin later this year. This will be followed by a full-scale ground test of a Rolls-Royce Pearl 15 jet engine, with the location yet to be decided. This builds on initial hydrogen combustion and fuel system rig tests that Rolls-Royce is performing in partnership with Cranfield and Loughborough universities in the UK.

Embraer and Brazilian fuel producer Raízen signed an LOI with the aim of increasing the development of sustainable aviation fuel (SAF) in the South American nation. Few details about timelines or the type and quantity of SAF were provided. However, the aim is that Raízen will help Embraer reach its target of having SAF blends representing 100% of its fuel consumption within Brazil by the end of the decade. Raízen is already a producer of ethanol, which is widely used as a motor vehicle fuel in Brazil and also to power Embraer’s agricultural aircraft. The company said it has already cut the equivalent of 30 million tons of carbon dioxide but aims to step up production to the tune of an extra 10 million tonnes per year.

Airbus and a number of major airlines—Air Canada, Air France-KLM, easyJet, International Airlines Group, LATAM Airlines Group, Lufthansa Group and Virgin Atlantic—signed letters of intent to explore opportunities for a future supply of carbon removal credits from direct air carbon capture technology. Direct Air Carbon Capture and Storage is a high-potential technology that involves filtering and removing CO2 emissions directly from the air using high powered fans. Once removed from the air, the CO2 is safely and permanently stored in geologic reservoirs. As the aviation industry cannot capture CO2 emissions released into the atmosphere at source, a direct air carbon capture and storage solution would allow the sector to extract the equivalent amount of emissions from its operations directly from atmospheric air. As part of the agreements, the airlines have committed to engage in negotiations on the possible pre-purchase of verified and durable carbon removal credits starting in 2025 through to 2028.
