 (Bedford, U.K.) is playing an important role in a new project, (EXperimental Aircraft for European Leadership in Aviation), that is developing the testbeds needed to pave the way for next-generation aircraft.

Led by the Dutch National Aerospace Laboratory (NLR, Amsterdam), EXAELIA is a 42-month €16 million project with 23 partners in 13 countries that are collaborating to develop knowledge around building and using smaller scale flying testbeds. These testbed research aircraft, which will be reused for additional flight test needs, will test new concepts and technologies and are crucial to help researchers and engineers learn how new technology long-range aircraft will work.

The project focuses on three main areas — tube and wing (TaW) aircraft with long, slender wings, blended wing body (BWB) airliners and new propulsion systems, particularly hydrogen propulsion. All of these novel technologies aim to significantly reduce the emissions from aviation, ultimately achieving net zero.

Cranfield is leading the design of the BWB testbeds, developing the legal paradigms and flight test practices for all testbeds, as well as making a major contribution to the design of hydrogen powertrains. Cranfield will also support four Ph.D. students in this work, who will graduate ready to work on the next stage of building and operating these testbed aircraft.

“Our involvement in EXAELIA builds on nearly 80 years of aeronautical innovation here at Cranfield,” notes Dr. Guy Gratton, associate professor of aviation and the environment, and also Cranfield’s principal investigator and leader in flight test practice work. “Reaching net-zero emissions from aviation requires a radical rethink of aircraft concepts, and this project has a crucial role in helping to de-risk and validate the technologies that will take us there.”

Gratton led the previous EnabEl (Enabling Aircraft Electrification) program and was the test pilot who made the first flight of the Sherwood eKub, said to be the first British designed and built all-electric conventional airplane. He is supported by reader in airframe systems, Dr. Craig Lawson, who is leading this project’s BWB design work.

EXAELIA project partners are also supported by Airbus, Safran, Rolls-Royce, MTU, GKN Aerospace, Collins Aerospace, Honeywell Aerospace Technologies, Piaggio Aerospace, KLM Royal Dutch Airline and ITP Aero.

Cranfield University, which also owns and operates Cranfield Airport, is exploring new aircraft designs and the potential for hydrogen in aviation, with a at any U.K. airport. According to Aviation Week, the university’s BWB expertise to the building of a full-scale blended wing fuselage mock-up in conjunction with the U.K.’s University of Greenwich, and its division, Cranfield Aerospace, building two X-48B experimental BWB aircraft for Boeing which were tested with NASA.
