Abstract
Engine thrust vectoring (TV) is a potential technology for military and future civil aircraft in which the Technion— Israel Institute of Technology has made signie cant contributions. This paper provides realistic predictions of steady-state engine performance during steady-state pitch vectoring. The results obtained comprise a required fundamental step for advanced aircraft/TV implementation. This work is a part of the Lockheed Martin yaw‐pitch TV F-16/F-100 research study conducted here at the Jet Laboratory. To this end, a unique TV-engine computer algorithm has been developed that expands the conventional steady-state modeling capabilities of onand off-design as well as the conventional transients (via throttle changes ) to create steady-state and dynamic TV‐engine simulations at various altitudes and Mach numbers. This paper reviews the steady-state performances and the optimization observations initially obtained. The subcritical e ow realm of nozzle performance provides trends aiding in the prediction of thrust benee ts beyond the conventional nozzle design of the F100 model are available as the effective nozzle throat area is allowed to contract through vectoring.
