| 摘要: |
| 由于外壁面的高温(l600K～1900K)条件，辐射冷却的推力室向外散失大量的热量。这一热量的散失，必然引起发动机比冲的损失。到目前为止，尚未看到这方面的计算方法。本文通过分析建立了计算内冷却(即有膜冷却)条件下的内部过程和考虑辐射热的外部过程所引起的比冲损失的公式。这些公式可在设计计算和性能估算时使用。 |

| Calculation of the Specific Impulse Loss for Radiative Cooling Thrust Chamber |
| Di Lianshun |
| Abstract: |
| The radiative cooling thrust chamber loses a considerably large quantity of heat due to high temperature of the outside wall，causing specific impulse loss of the engine. Up to now，no calculating methods for this problem have been found yet. In this paper， formulae of the specific impulse loss for the inside and outside processes are estab1ished. These formulae are a part of formulae for the design calculation and
the performance assessment. |
