Aircraft Research Association (ARA) is a UK-based aerodynamics research institute working on innovative projects for the world’s major commercial aircraft and defence manufacturers. It recently set out to test a long-term theory that could make long-haul flights more efficient as countries move towards net zero.
Using Teledyne FLIR thermal imaging cameras during testing, ARA proved its theory correct. The research will have a direct impact on increasing flight efficiency on future aeroplane designs.
