| Abstract: | Hypersonic characteristics of bented maneuvering reentry vehicle were calculated and analysed. Effects of location of center of gravity on trimming angle of attack were studied. Essential and sufficient conditions of steady trimming about three directions were presented. Trajectory of spiral flight was imitated by the coupling calculation program of aerodynamic and six dimension trajectory equations. The most important key for a successful design is the control of crosswise movement of the gravity center. |
