Problems solved by technology

Relying on the deflection of the empennage rudder surface to realize the attitude adjustment of the airship mainly has two problems: one is that as the volume of the airship gradually increases, the length of the airship capsule increases, and the installation position of the empennage on the airship (generally, the leading edge of the empennage root is at a distance from the capsule head). The lower part is the position of 75% of the length of the hull) the farther away from the center of mass of the airship, the longer the control arm of the empennage. Under the action of wind load, it is difficult for the empennage rudder surface to overcome the nose-up/down momen

Abstract

The invention discloses an airship tail vectored thrust device which mainly comprises a tail cone, a two-degree-of-freedom rotary table base, a Z-axis rotating body, a Y-axis rotating body and thrust devices. When the airship tail vectored thrust device is operated, deflection of the Z-axis rotating body and the Y-axis rotating body drives the thrust devices to enable the same to rotate tipsily in an airship body plane and a vertical plane within the range of +/-90 degrees, and a certain vectored thrust is generated, so that pitching and yaw attitude adjustment and auxiliary acceleration of an airship are achieved. By the aid of the airship tail vectored thrust device, response speed of airship attitude (pitching and yaw) adjustment is remarkably increased, control torque is increased, flying speed is increased in an assisted manner, and environmental adaptability of the airship is enhanced.

Description

technical field [0001] The technology relates to a tail vector thrust device of an airship, which is used for pitch and yaw attitude adjustment during the flight of the airship, and can assist in increasing the flight speed of the airship, belonging to the field of aerostat control. Background technique [0002] Existing airships mainly rely on the deflection of the tail rudder surface (skin skeleton type or inflatable membrane type) to realize the pitch and yaw control of the airship, thereby realizing the turning, climbing, and descending actions of the airship. The deflection effect of the empennage rudder surface (skin skeleton type or inflatable membrane type) is limited by the wind load, and the deflection range is generally within ±30°. Relying on the deflection of the empennage rudder surface to realize the attitude adjustment of the airship mainly has two problems: one is that as the volume of the airship gradually increases, the length of the airship capsule increa...
