Based on the experiment data, I analyze the regulation of rolling characteristics, lift characteristics, drag characteristics and pitching moment characteristics wi.

The major problem is the longitudinal trim problem caused by the momentum drag and the pitch moment created by the duct.

Research on the modeling of pitching moment coefficient in transonic condition for flight vehicle;

In virtue of Fluent of CFD software,we carry though computation of aerodynamics of an air-to-air missile in different Mach meter and different attack angle and gained movement trend of lift coefficient、drag coefficient and pitching moment coefficient with variety of Mach number and attack angle,meanwhile,we also obtain distributing trend of pressure,temperature and weather velocity.

When angle of attack is changing from-10° to 7°,the effects of viscosity on the lift,drag force and pitching moment characteristics of hypersonic vehicle in three working conditions including inlet closed,inlet open but unfired,inlet open and fired were discussed.

Two-dimension coupled implicit Naviers-Stokes equations and standard k-ε viscid models were introduced to simulate the lift characteristic,drag characteristic,pitching moment characteristic and lift-to-drag ratio characteristic of integrated hypersonic vehicle with Hark head configuration working under the conditions of inlet closed,inlet open but unfired and inlet open and fired.
