Aircraft without aileron
In order to make the aircraft easier, faster and more secretive, you can get rid of the moving ailerons and rudders on its wings and tail. This idea was realized by specialists of the well-known defense company BAE Systems, who worked together with scientists from the University of Manchester.
MAGMA UAV (Unmanned Aerial Vehicle) drone, created by their joint efforts, maneuvers and changes the direction of flight by distributing and controlling the direction of the flow of exhaust gases from its only jet engine.
Instead of the ailerons, there are a number of narrow slits on the rear edge of the wings of the MAGMA drone. Part of the engine exhaust gases is diverted from the total flow and pulled out of these slots at supersonic speeds. Using the distribution of the flow of exhaust gases emerging from the cracks at the ends of the wings, one can control the vector of thrust created by them and change the direction of flight as if the ailerons are installed on the wings.
It should be noted that this system is no longer new, BAE Systems used similar traction vectoring technologies in the UAV DEMON UAV.
But, in addition to replacing the aileron with variable vector exhaust streams, the MAGMA drone used a similar method of controlling the main flow vector from the jet engine. Behind the engine outlet is a surface having a certain curvature. Under normal conditions, the exhaust flow "adheres" to this surface and is directed at a certain angle to the direction of the engine outlet nozzle. In this curve of the “deflecting” surface there are also narrow slits through which a part of the exhaust gases hits perpendicular to the direction of the main flow, deflecting it to the side. And the stronger the flow of exhaust gases spurting from the cracks, the greater the angle of the main thrust vector generated by the engine.
“We have already planned a flight test program for the MAGMA UAV, which will begin in a few months. The main goal of this event is to demonstrate the capabilities of the vectoring technology, which allows you to do without any moving parts and components, including the ailerons,” says BAE representatives. Systems, - "In case of success of the test, we are going to equip with the same vectorization systemthrust and full-scale aircraft with a single gas turbine jet engine. "
