Book Description
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 aircraft flight control. Analytical modeling of thrust-vectoring nozzles has been at best fragmentary in publicly available literature in the past. For robust nozzle modeling not only the internal fluid mechanics need to be considered, but the dynamic geometry of the nozzle as well as the influence on the forces obtained from the jet by the flight velocity and angle of attack of the aircraft. With the fervent research into vertical flight capabilities as in the Joint Strike Fighter program, among other aircraft, the influence of the ground effect on the jet must also be considered. In all of this, the foundation of analysis lies in the understanding and modeling of aircraft nozzle performances; both conventional and thrust-vectored. This book seeks to lay a foundation for such work.

Book Description
An investigation was conducted in the Langley 16-Foot Transonic Tunnel to determine thrust vectoring capability of subscale 2-D convergent-divergent exhaust nozzles installed on a twin engine general research fighter model. Pitch thrust vectoring was accomplished by downward rotation of nozzle upper and lower flaps. The effects of nozzle sidewall cutback were studied for both unvectored and pitch vectored nozzles. A single cutback sidewall was employed for yaw thrust vectoring. This investigation was conducted at Mach numbers ranging from 0 to 1.20 and at angles of attack from -2 to 35 deg. High pressure air was used to simulate jet exhaust and provide values of nozzle pressure ratio up to 9. Capone, Francis J. and Mason, Mary L. and Leavitt, Laurence D.
