Abstract

The invention discloses a variable mass center aircraft simulation device and relates to an aircraft simulation device. The invention aims to solve the problems that the conventional aircraft corresponding to a variable mass center control manner does not have good aerodynamic configuration and a side-jet engine manner cannot be maneuvered by fully utilizing aerodynamic force. According to the variable mass center aircraft simulation device disclosed by the invention, two frame coupling shafts are arranged on a support frame; a conical bottom surface of an aircraft shell is hinged with the support frame through the two frame coupling shafts; the conical tip of the aircraft shell is downward; the aircraft shell can swing around the frame coupling shafts; a moving mass body is positioned inside the aircraft shell; the conical tip of the moving mass body is hinged with the conical tip of the aircraft shell; a stepping motor and a gear are arranged on the conical bottom surface of the moving mass body; an arc-shaped movement rack is fixed on the conical bottom surface of the aircraft shell; the gear and the movement rack form a kinematic pair; the stepping motor drives the moving mass body to swing inside the aircraft shell by virtue of the kinematic pair. The variable mass center aircraft simulation device disclosed by the invention is applicable to design and control studies of variable mass center aircrafts.

Description

technical field

[0001] The invention relates to the field of aircraft control, in particular to an aircraft simulation device. Background technique

[0002] In the field of aircraft control, the characteristics of variable center of mass control make it widely used, such as extra-atmospheric aircraft, underwater aircraft and intra-atmospheric aircraft. Among them, the variable center of mass control of aircraft in the atmosphere is a current research hotspot. The current research on variable center of mass control technology mainly focuses on re-entry vehicles and interceptors. work has been carried out. However, the hardware implementation of variable centroid configuration has not progressed yet.

[0003] The variable center of mass control technology is to actively move the movable mass body inside the aircraft, change the position of the center of mass of the system, and cause the external torque acting on the aircraft to change to obtain the desired control torque, so...
