Embodiment Construction

[0015] The present invention is an experimental platform with three degrees of freedom and integrating flight control and guidance simulation. It includes a platform base 1, a support swing arm 2 and a flight carrier 3. The platform base 1 is a three-layer columnar stacked structure, supplemented by pallet columns for structural reinforcement. The interior of the platform base 1 is equipped with a rotating shaft system. The vertical rotating shaft 4 is supported by the bearing 5 and can rotate 360°. Freedom of motion, the vertical shaft 4 is hollow inside, the upper end is connected to the U-shaped bracket 11, and the lower end is connected to the collector slip ring 6, in order to avoid the entanglement and winding of many wires due to the rotation of the platform, the motor power supply, control signals and sensor signals, etc. All wires are routed through the current collector slip ring 6, and the wires of the current collector slip ring 6 pass through the inside of the ver...

Abstract

The present invention is an experimental platform with three degrees of freedom, which integrates flight control and guidance simulation. It adopts a four-link structure design to support the swing arm, the upper swing arm, the lower swing arm, the vertical link and the U-shaped bracket. A parallelogram is formed to provide a horizontal reference for the front-end flight carrier. The seeker module is mounted on the front-end flight carrier, which has two degrees of freedom of pitch and yaw. The position marker can use one or more sensors such as CCD cameras and infrared sensors to simulate single or composite missiles such as TV and infrared. Guidance, integrating the guidance dynamics simulation of the missile into the flight control. The invention can simulate the direct force control of the flight carrier and study the compound control technology of aerodynamic and direct force. The air flow nozzle installed at the front end of the upper swing arm can spray compressed air in four directions up, down, left, and right under the control of the electronic air valve. The invention can carry out the inertial navigation simulation experiment of the aircraft, and an inertial measurement unit is installed in a strapdown inside the flight carrier.

Description

technical field [0001] The invention relates to a flight simulation platform for guidance control technology. technical background [0002] At present, the Three Degrees of Freedom Helicopter Model (Three Degrees of Freedom Helicopter Model) produced by Canada's Quanser Company discloses a flight simulation platform used for control research. The three-degree-of-freedom helicopter model consists of a helicopter, a support rod, a slewing bracket, and a base. The helicopter adopts a tandem fan layout, the two motors are directly connected to the propeller drive, the speed can be independently controlled, and the helicopter can rotate around the support rod, which is the degree of freedom in pitching; one end of the support rod is connected to the helicopter model, the other end is connected to the counterweight, and the middle part of the support rod is suspended It is hinged on the slewing bracket and can rotate around the fulcrum, which is the degree of freedom of lifting; ...
