Abstract
Parametric system identification procedures, using the software package MATRIXx, are applied to the problem of simulating the thermal response of a TVC jet vane. The jet vane is discretized into thermal lumps and energy balances are written to develop the governing mathematical relationships. Boundary layer convection and stagnation point heating are considered as thermal inputs, and the associated resistances are estimated. System identification is used to determine the appropriate values for the convective resistances and the vane mount thermal sink. The identified model, which is linear time-variant, closely predicts the thermal response of the jet vane shaft, surface and tip. Keywords: Thrust vector control systems
