Abstract:
The requirement of performance for liquid ramjet is higher and higher with the constant increase of battle sky and flight velocity of the cruise missile. It is necessary to analyze and research the influence factors on the liquid ramjet performance. According to detailed analysis of liquid ramjet working process, the software of ramjet performance computation is programmed, and each key subassembly of ramjet is analyzed by using this performance calculation software. In order to make sure the primary factors and subassemblies that affects ramjet performance, the affection of every key subassembly (such as intake, combustion chamber, tail nozzle, fuel supply system, and so on) on the thrust and specific impulse of ramjet performance is determined. Calculation and analysis results indicate that the impulse efficiency of tail nozzle is the most direct and important affection factor on ramjet performance. Moreover, air flowrate that drives turbine, and the efficiency of combustion chamber are the more important factors that affect ramjet performance.
