为开展燃烧室的传热特性等研究,采用了以紫铜作为材料的容热式推力室身部,通过测量热试车过程中身部壁温,来获得推力室内壁温度、热流沿轴向的分布。为测量数据设计了数据处理方法,以利用测得的温度值获得内壁温和热流值,且进行了主要误差估计。将该方法在气气喷注器推力室上进行了应用,研究了其传热特性。 In order to study the heat transfer characteristics of the combustion chamber, the bulk of the heat-conducting thrust chamber is made of copper as the material. The temperature of the inner wall of the thrust chamber and the distribution of the heat flow in the axial direction are obtained by measuring the body wall temperature during the heat test. A data processing method was designed for the measurement data to obtain the mild heat flux value of the inner wall by using the measured temperature value, and the main error was estimated. The method is applied to the thrust chamber of the air injection device to study its heat transfer characteristics.
