In this model, the velocity was controlled below50 m /s so that it is easy that the temperature of outlet propellant exceeds 1000K. By the measure of advancing the melting point of metal panel to 3000K, the temperature of outlet propellant even could be close to the very high temperature of the metal panel. It is very active to improve the capability of the whole propulsion system.

在本文模型中，将管道内工质的流速控制在50 m /s ，热交换器的出口工质温度就能够提升至1000K以上；提高换热器高温加热段的金属平板熔点到3000K以上，完全可以将工质出口温度提升至接近金属平板的温度，这样可以大幅度提高推进系统的性能。
