比冲动

Specific impulse

比冲动是描述火箭和喷气发动机效率的一种方式。 它表示相对于每单位时间使用的推进剂的量的力。 如果以质量给出推进剂的“量”,则比冲量具有速度单位。 如果是按重量给出,那么具体的冲动有时间单位。 特定脉冲的两个版本之间的转换常数为g。 比冲击越高,给定推力所需的推进剂流速越低,在火箭的情况下,根据Tsiolkovsky火箭方程,给定的delta-v需要较少的推进剂。 实际的排气速度是排气射流离开车辆时的​​平均速度。 有效排气速度是在真空中产生相同推力所需的排气速度。 对于在真空中工作的理想火箭来说,两者是相同的,但是对于通过加速空气获得额外的推力的空气呼吸喷气发动机来说,这两者是完全不同的。 比冲程和有效排气速度成比例。 Specific impulse is a way to describe the efficiency of rocket and jet engines. It represents the force with respect to the amount of propellant used per unit time. If the "amount" of propellant is given in terms of mass, then specific impulse has units of velocity. If it is given in terms of weight, then specific impulse has units of time. The conversion constant between the two versions of specific impulse is g. The higher the specific impulse, the lower the propellant flow rate required for a given thrust, and in the case of a rocket the less propellant is needed for a given delta-v per the Tsiolkovsky rocket equation. The actual exhaust velocity is the average speed of the exhaust jet as it leaves the vehicle. The effective exhaust velocity is the exhaust velocity that would be required to produce the same thrust in a vacuum. The two are identical for an ideal rocket working in a vacuum, but are radically different for an air-breathing jet engine that obtains extra thrust by accelerating air. Specific impulse and effective exhaust velocity are proportional.

在英语 词典里specific impulse的定义

字典中的具体冲动的定义是火箭发动机产生的推力与燃料消耗率的比率:它具有时间单位,并且是如果用于产生一个单位的推进剂的单位重量将持续的时间长度 持续的推力。

The definition of specific impulse in the dictionary is the ratio of the thrust produced by a rocket engine to the rate of fuel consumption: it has units of time and is the length of time that unit weight of propellant would last if used to produce one unit of thrust continuously.
