Description: 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.
