Design-oriented research of air mass flux characteristic for scramjet
摘要
Abstract
With regard to air mass flux characteristic of scramjet for airbreathing hypersonic flight vehicle,mathematical model of design-oriented air mass flux characteristic was derived by means of force analysis,energy conservation principle,specific impulse definition and so on.What’s more,design-oriented air mass flux characteristic was contrasted and analyzed in combination with in-stance in terms of quantitative and qualitative analysis.The results show that air mass flux obviously decreases by making use of hy-drocarbon fuel and air launch.Variation trend of cruising range was contrary to that of cruising speed,which requires optimization a-bout the both parameters.Air overflow and appropriate equivalent specific fuel consumption were required with mass reduction during cruise flight.关键词
