Agency defense advanced research (DARPA) of the Ministry of defense has selected three bidders CRANE (Control of Revolutionary Aircraft with Novel Effecters, management of a principally new aircraft with innovative actuators) for the development, Assembly and testing of the plane, completely devoid of mechanization of the wing. As writes to Defence Talk, in the first stage of the tender participants will be required to identify system, which can be used for flight control instead of the traditional mechanization.
Modern aircraft flight control is made by means of movable aerodynamic elements, otherwise known as mechanization. There is a mechanization of the wing and tail, driven by electric, mechanical or hydraulic systems. With the help of mechanization, the pilots can control not only the direction of flight of the aircraft in space, but also the formation of a lifting force on the wing, or the speed of the aircraft.
The CRANE project involves the complete replacement of traditional mechanization, which is made by the flight controllers on the active system of air flow control (AFC). The new system on the aircraft must be used throughout flight from takeoff and landing before the flight at high altitude. It is assumed that the use of active systems to control air flow will make advanced aircraft easier and cheaper to maintain due to fewer moving parts.
To participate in the tender CRANE, the United States Agency allowed the company Aurora Flight Sciences, Lockheed Martin and the Georgia Tech Research Corporation. These companies will need to identify technologies and technical solutions that will influence the boundary layer on the airframe, thus allowing you to control its flight. The timing of the first stage of the tender is not specified.
In 2017, a British company, BAE Systems conducted the first flight test of unmanned aircraft Magma, which flight control system is responsible, which selects a portion of the air from the jet engine and through the channels of forwarding it to the nozzles on the wing and in the nozzle of the engine. Blowing air from the nozzle is supersonic; it is therefore possible to control the flight of the drone.
