| Abstract: | The article divides a typical cruise high Mach number aircraft into take-off and rollingphases , accelerated climb phases , cruise flight phases , dive flight phases , glide return phases , landingand roll-off phases ,etc. ,on the basis of carrying out force analysis on different phases. The voyageperformance estimation method at each phase and the weight change processing method at each phases were theoretically deduced, forming a full-section voyage performance estimation and weight pro.cessing method suitable for the high Mach cruise off-board concept design stage. Finally , through theanalysis of specific examples, the performance of a cruising speed of Mach number 3.5 was esti-mated and analyzed to verify the effectiveness of the method. |
