The BAE Systems MAGMA UAV demonstrated maneuvering flight through the use of flow control earlier this year in Wales. BAE Systems

Key Takeaways:

  • DARPA has launched the CRANE (Control of Revolutionary Aircraft with Novel Effecters) program to develop revolutionary aircraft that use Active Flow Control (AFC) as a primary design element, aiming to eliminate traditional moving control surfaces.
  • The CRANE program seeks to design, build, and flight-test a novel aircraft optimized for AFC to demonstrate new trade spaces for future designs and improve performance across various flight aspects.
  • The feasibility of flight control without traditional surfaces is already gaining traction, as evidenced by BAE Systems' successful flight of a UAV utilizing flow control.

When the Wright Brothers designed the original Flyer, a critical element to their success laid in the refinement of the flight controls they used—wing warping—to guide the craft through the air.
