A high-altitude airship and its yaw control method

Abstract

The invention relates to the technical field of aerospace and discloses a high-altitude airship and a yaw control method thereof, wherein the high-altitude airship comprises: two vector propulsion assemblies arranged on the front and rear sides of the belly of the high-altitude airship; The tension axes of the components are inclined upwards and downwards at the same angle with respect to the horizontal plane. In the high-altitude airship and the yaw control method thereof provided by the present invention, two sets of vector propulsion assemblies are arranged in the front and rear, and the distance can be maximized to increase the yaw moment generated by the pulling force of the propulsion assemblies on the center of mass of the boat body; One of the vector propulsion assemblies is inclined upward and the other is inclined downward, so that the vertical components of the pulling forces generated by the two vector propulsion assemblies can cancel each other out or be minimized, which is beneficial to reduce the impact of yaw control on the hull. The pitching moment can reduce the influence on the attitude of the airship, ensure the flight performance of the airship, and reduce potential dangers.

Description

technical field [0001] The invention relates to the technical field of aerospace, in particular to a high-altitude airship and a yaw control method thereof. Background technique [0002] At present, the flight speed of high-altitude airships is low, and the air density at high-altitude is thin, so it is difficult to realize yaw control by using the aerodynamic force of the rudder surface. Generally, high-altitude airships use vector thrusters to generate deflectable pulling force for yaw control, and the vector thrusters are located in the hull of the boat. In the lower part, there is a certain distance from the center of mass of the hull. When the thruster generates a pulling force, it will generate a pitching moment that makes the airship keep raising its head, so that the angle of attack of the airship will continue to increase. The increase of the angle of attack of the airship will greatly increase the resistance of the hull. The flight performance of the airship is red...
