YAW CONTROL DEVICE FOR A NOZZLE HAVING A RECTANGULAR OUTLET SECTION

摘要

The present invention relates to a control device in the lace to aircraft (100) equipped with a supersonic nozzle (110) with a rectangular cross section or flattened comprising a sonic throat (111) extended by a divergent nozzle (112) in which the supersonic flow (esup). In order to allow the yaw control of the aircraft in the absence of the vertical tail fin, the device of the invention employs the control surfaces of the jet (120) in the form of a fin which are disposed in the diverging part (112) of the nozzle. The control surfaces are movable about an axis of rotation (121) to generate a lateral force in the deflected position and allow the rotation of the aircraft (100) about the yaw axis (102).
