摘要
探讨了以火药燃气作为工质的运载火箭中所用的冲击式涡轮效率提高的途径。给出了具有小反力度冲击式涡轮效率的计算方法和火药燃气中含有微粒流时冲击式涡轮效率的选代计算方法。对四种情况下计算结果进行了对比分析。计算结果与试验结果符合良好。
A study on the way to increase efficiency of impulse turbine is presented.An approach method is applied to calculate efficiency of impulse turbine even in low reaction degree conditions' The effect of working substance which contains solid praticles on the turbine efficiency is also investigated.The numerical results shown a good accordance with the experimental data under four conditions.
