摘要：

A hypersonic vehicle flying in near-space requires strict control characteristics of aerodynamic rudder. Rudder efficiency is seriously effected by wing at hypersonic speed in near-space, hypersonic aerodynamic characteristics of a lifting-body with the all-movable rudder is studied by using a wind tunnel test. Compared with positive rudder deflection, negative rudder deflection influences the aerodynamic characteristics of the lifting-body obviously because of wing sheltering effect, numerical simulation shows rudder surface pressure distribution varies with airstream interference between wing and rudder, rising moment is produced at -12°~2° rudder deflection while yielding moment is produced at other rudder deflection, the separate line of wing trailing edge moves toward to the warhead as the angle of attack increases, high pressure airstream develops upward through the gap between wing and rudder, causing the attach line of rudder leeward surface moves backward, and lateral flow could also be observed on their surfaces.
