BAE Systems trials new flight control technology which replaces mechanical flaps with jets of air

BAE Systems and The University of Manchester say they are “set to change the future of aircraft design” with the unique flight control technology they are trialling.

BAE Systems trials new flight control technology which replaces mechanical flaps with jets of air

BAE Systems reports that, with The University of Manchester, it has successfully completed the first phase of flight trials with MAGMA – a small scale unmanned aerial vehicle (UAV), which will use a unique blown-air system to manoeuvre the aircraft, potentially paving the way for future stealthier aircraft designs.

How it works

The new concept for aircraft control removes the conventional need for complex, mechanical moving parts used to move flaps to control the aircraft during flight. This, BAE says, could give greater control as well as reduce weight and maintenance costs, allowing for lighter, stealthier, faster and more efficient military and civil aircraft in the future.

The two technologies to be trialled first using the jet-powered UAV, MAGMA, are:
 
• Wing Circulation Control, which takes air from the aircraft engine and blows it supersonically through the trailing edge of the wing to provide control for the aircraft
• Fluidic Thrust Vectoring, which uses blown air to deflect the exhaust, allowing for the direction of the aircraft to be changed.

The flight trials are part of an ongoing project between our two organisations and wider long-term collaboration between industry, academia and government to explore and develop innovative flight control technology.

Further flight trials are planned for the coming months to demonstrate the novel flight control technologies with the ultimate aim of flying the aircraft without any moving control surfaces or fins.

If successful, the tests will demonstrate the first ever use of such circulation control in flight on a gas turbine aircraft and from a single engine, the partners say.

“Groundbreaking”

Clyde Warsop, Engineering Fellow here at BAE Systems, said: “The technologies we are developing with The University of Manchester will make it possible to design cheaper, higher performance, next generation aircraft. Our investment in research and development drives continued technological improvements in our advanced military aircraft, helping to ensure UK aerospace remains at the forefront of the industry and that we retain the right skills to design and build the aircraft of the future.”

Bill Crowther, a senior academic and leader of the MAGMA project at The University of Manchester, adds: “These trials are an important step forward in our efforts to explore adaptable airframes. What we are seeking to do through this programme is truly ground-breaking.”

Additional technologies to improve the performance of the UAV are being explored in collaboration with the University of Arizona and NATO Science and Technology Organisation.

    Gents ,
    I remember reading about research (years and years ago) regarding in-wing air flow being directed through selected vents to provide flight controls. This was applicable to all control surfaces. It could also be used as an air flow modifier to improve air flow on top of wings (slats?).
    Great idea, but don't you wish you had thought of it first?
    Think of the possible stealth advantages of non moving control surfaces
