Thrust at zero speed is zero power. Power requiresworkto be done, so zero velocity indicates zero work and zero power. Therefore the power of a rocket or aircraft engine is thrust times forward speed. power (watts) = thrust (newtons) x speed (metres/second) ...
1.In order to improve muzzle velocity of rocket projectile and reduce force of back exhaust gas acting on launcher device,multiperforated grain structure of single-chamber dual-thrust rocket motor was put forward.为有效提高火箭弹炮口速度,减小发动机后喷燃气对发射装置的作用力,提出了单室双推力多孔装药...
This paper presents a method of thermal state calculation of combustion chamber in small thrust liquid rocket engine. The goal is to predict the thermal state of chamber wall by using basic parameters of engine: thrust level, propellants, chamber pressure, injection pattern, film cooling parameters...
For LOX/LCH4 electric expander cycle variable thrust rocket engine (Fig. 1), the propellant methane is traditionally selected as the coolant in the RCC. Propellant methane absorbs heat in the RCC and then enters the thrust chamber for combustion. With the decrease of engine thrust, the mass ...
