Thrust-vectoring flight control is a leading-edge technology now being implemented in production aircraft such as the F-22, Su-37 and MiG 35. It significantly increases aircraft maneuverability and capability through enabling the use of jet-deflection as an alternative or enhancement to conventional ...
The F-22 [24] adopted thrust vectoring in one plane. Both nozzles are parallel and could influence only the pitch rate of the aircraft. Yaw rate control was not used because it requires a more sophisticated mechanism to lower the stealth capabilities. There were a number of experimental ...
The external flaps (32), which contain the ram air, continue to form a conical structure during vectoring. External flaps (32) are hinged to the unison ring (30) with ejector flaps (34) hinged to the

Geometrically variable converging-diverging thrust-vectoring nozzles, such as the two-dimensional pitch-only type on the F-22 and the axisymmetric yaw-pitch type tested in the F-15 ACTIV program, directly affect the jet flow geometry and rotation angle at the nozzle exit, thus altering the ...

An inner-outer loop modular control structure is used to provide good flying...
to provide thrust vectoring, a single deflection door is deployed to deflect one of the fluid streams away from the other. Since the undeflected fluid stream is angularly discharged toward the axial centerline of the nozzle, the undeflected fluid stream joins with the deflected fluid stream so ...

A gas turbine engine turbine has a high pressure turbine configured to rotate with a high pressure compressor as a high pressure spool in a first direction about a central axis and
The rocket considered in this study is equipped with a single motor, so the thrust vectoring allows the control of the motion in the pitch–yaw angle without any effect on the roll motion. The analysis considers the pitch angle as the only measured system output. The design requirements for ...
