Keywords: secondary injection thrust vector control (sitvc), infrared thermography (irt), convective heat transfer coefficient, horseshoe vortex

In this study, thermal analysis near a secondary injection hole was conducted. The pressure-sensitive-paint was employed for flow characteristic measurement. And infra-red thermography also performed to obtain the thermal characteristic around the injection hole. Thermal stress around the injection hole is calculated from these two results by commercial package ANSYS.
