Modeling Transient Thermal Behavior in a Thrust Vector Control Jet Vane

Abstract

An attempt was made to model the transient thermal response of jet vanes used for thrust control. A simple computer model based on lumped capacitance methods using boundary layer convection and stagnation point heating as thermal inputs appeared to adequately predict temperatures for a quarter- scale model. This report details the attempt to enlarge the model to allow comparison between thermal predictions and the results of tests on a full-scale prototype jet vane. It was determined that the model could not be considered a thermal representation of the full-scale vane assembly and several modifications were identified order to adapt the model to full-scale applications. Keywords: Thrust vector control, Jet vane, Theses.
