Abstract:

A full-scale model of a double-wedge, simulating a jet vane used in guided missile thrust vector control TVC, was constructed for subsonic wind tunnel testing to evaluate the feasibility of using a thermal imaging infrared system vice thermocouples to determine a surface heat transfer coefficient. The model was preheated, then allowed to cool via forced convection to ambient conditions. Surface temperature readings were taken using thermocouples and a thermal imaging system during the cooldown process. These readings were then reduced to solve for a heat transfer coefficient h, using Newtons Law of Cooling. The results were compared with the theoretical solution for a flat plate and with the results obtained by testing an actual TVC vane configuration under the identical flow conditions. Theses
