Research on Conic Support in Radiant Cooler for Infrared Detector

We have investigated the conic support In the radiant cooler for Infrared detector by using finite element method. Results show that the stiffness of the support increases with an increasing of the coning angle in case of launched state, while the situation is reversed in the orbited state. It is also found that the heat loss of the support caused by the thermal conduction decreases with the reduction of the coning angle. Moreover, the optimized coning angle is provided as a function of the thickness.
