solid-propellant rocket engine

The temperature of a high temperature, high pressure plume solid propellant rocket engine is difficult to measure but is useful for determining the combustion status of the engine.

对于固体火箭发动机羽焰温度的测量是困难的，了解其温度分布对于研究发动机内燃烧流场的特性有重要价值。

The plume temperature is an important parameter, for solid propellant rocket engines and it is useful for determining the combustion process of the engine.

推进剂的羽焰温度是固体推进剂火箭发动机的重要参数，对于研究发动机内的燃烧过程具有重要价值。

As the air-breathing engine, the performance of solid rocket ramjet is determined not only by structure of engine and the performance of propellant, but also by flight condition.

作为吸气式发动机，其性能不仅取决于发动机本身结构和推进剂性能，与飞行状态也有密切的联系。
