摘　　要：Lift-to-drag ratio (L/D) is nearly the most important index in determining the aerodynamic performance of a hypersonic flight vehicle,because the flight distance is linearly proportional to the L/D according to Breguet's equation.In general,the higher the L/D of a vehicle,the greater the flight range if the specific impulse,structural mass ratio,and flight velocity are given.Naturally,the pursuit of a high L/D for hypersonic vehicles has never ceased [1,2].
