脉冲爆震轴功率输出装置性能分析与对比
Performance Analysis and Comparison of Pulse Detonation Shaft Power Device
摘要
Abstract
A general performance calculation model was established for the pulse detonation shaft power device (PDSPD) with pulse detonation combustor (PDC).The detonation chamber model used PDC characteristic diagram.The influence of operating parameters on the pedormance of PDSPD was studied.The study results show that:under constant operating frequency,the power per liter and the shaft power rise with the increase of the pressure ratio,while the specific fuel consumption decreases;there is an optimum pressure ratio when the specific power reaches its maximum value;under constant pressure ratio,the power per liter of PDSPD rises with the increase of operating frequency.The pedormance of PDSPD and other three shaft power devices were compared under different operating conditions.The comparison results show that the specific fuel consumption level of PDSPD is close to that of the diesel engine at the same displacement and shaft power.Compared with the gasoline engine,PDSPD's specific fuel consumption level decreases with the same shaft power in a certain range of pressure ratios.Compared with the turbo-shaft engine,the specific power of PDSPD increases by more than 38.08％,and the specific fuel consumption decreases by 41.42％.Therefore,the propulsion,economy and thrust weight ratio of the engine are greatly improved.关键词
