Abstract
This work describes the development of a computer based model that would allow for determination of the transient thermal response characteristics of jet vanes of any size. The model used a thermal lump approach method, considering only conductive and convective heat transfer properties. A constrained optimizer was used to adjust the unknown variables until an adequate match was achieved between the calculated values of the energy balance equations and the experimental data obtained from test firings of a rocket motor. The full scale modeling results were compared to previous quarter scale models in an attempt to determine the applicability of the quarter scale results to full scale vanes. It was determined that the quarter scale model did not provide an accurate representation of the heat transfer process in larger scale vanes, although the full scale model provided a sufficient representation of the thermal response of the jet vane.
