摘要
在舰船用新型推进器的研究和探索中,依据火箭喷气式发动机的工作原理,设计了一 种喷气式推进模型,并确定了推进模型反应室和喷嘴的结构尺寸.实验结果表明:长度为1.15m,质 量为25kg的模型船在喷气式推进模型的作用下,推力可达1.45N,行驶速度可达9.5cm/s.
A jet propulsion model was designed and the structural dimensions of its reaction chamber and jet nozzle were determined referring to the operating principle of the jet engine in the exploration and investigation of the newfashioned propulsion for the watercraft. It could conclude from the experimental results that the model of a ship with 25 kg weight and 1.15m length was at a speed of 9.5 cm/s and could achieve a jet thrust of 1.45N by using the propulsion model.
