CONTROL OF AIRCRAFT BY MEANS OF THRUST VECTOR CONTROL Russian patent published in 1998 - IPC

FIELD: aircraft control system. SUBSTANCE: system includes swivel nozzles of engines connected with functional units which are interconnected in series. System is provided with computers for longitudinal and directional control of aerodynamic surfaces, angle-of-attack, ram air-pressure and altitude sensors. System is also provided with non-linear amplification angle-of-attack corrector, electronic and summing amplifiers, non-linear amplifiers of longitudinal and directional control of aerodynamic surfaces and nozzle adders. Provision is also made for velocity head and nozzle height correctors, minimum signal selector. Nozzles are arranged at angle relative to axis of their turn. Deflection of nozzles is accomplished in limited range of velocity heads and altitudes. EFFECT: enhanced reliability of system; increased service life of nozzle. 3 dwg
