摘要
Abstract
In order to satisfy the temperature requirement inside the hypersonic vehicle' s capsule,the thermal control method applying the phase change material (PCM) to the heat short regions of the rudderpost was proposed.Through the temperature control experiments of the thermal conductivity enhanced PCM,the temperature curves of the rudderpost and the metallic capsule under different schemes were achieved.The experimental results revealed that the thermal conductivity enhanced PCM could absorb the heat well and decrease the temperature of the heat short regions obviously.By using the PCM devices under the low temperature and middle temperature inside and outside the metallic capsule,the temperature of the capsule around the rudderpost could be controlled within the range of working permission.The results would be helpful to guide the temperature control design for the rudderpost of the vehicle.关键词
