裂解度对甲醇ATR发动机的性能影响分析
|
摘要
提出了一种基于甲醇裂解工作的ATR发动机方案,并对特定裂解气成分的甲醇ATR发动机性能进行计算,研究了裂解气中裂解度对发动机性能的影响规律。结果表明:随着发动机转速上升,推力逐渐上升,比冲先增加后减小,在90%转速百分比时,比冲最高;在同一转速下,甲醇裂解度越高,发动机比冲越大,在裂解度100%、转速百分比90%条件下,发动机比冲最高达到约793 s;随着裂解度逐渐升高,裂解气比热容逐渐升高。
A new ATR( Air Turbo Rocket) engine scheme based on the methanol cracking is proposed in this paper. The performance of methanol ATR engine with specific composition of cracking gas is calculated,and the influence of cracking ratio on the engine performance is investigated. The results show that the thrust gradually increases,and the specific impulse increases first then decreases as the engine speed increases. The specific impulse reaches the top at the 90% designed speed. Under the same engine speed,the higher the cracking ratio of methanol,the greater the specific impulse of engine. Under the condition of 100% cracking ratio and 90% rotation speed,the specific impulse is up to 793 s. In addition,the specific heat capacity of cracking gas increases with the increase of cracking ratio.
