AB - The paper discusses the temperature changes in mechanical jet tabs in a  system of rocket motor thrust vector control, estimated by the simulation and  experimental tests methodology. The heat transfer calculation is based on  complex computational fluid dynamics simulations of both the nozzle and  external tab flows, as the comprehensive integral flow zones with high flow  parameters gradients. Due to a complexity of the model for flow calculations,  the experimental estimation of the calculated results is carried out. The  temperature is measured by jet tabs embedded thermocouples, and conducted  through the rocket motor static tests. A good agreement of the calculated and  measured results is achieved. The main aim of the developed method is to  establish an approved calculation tool for designing new TVC systems in order  to avoid disadvantages due to overheating.
