Embodiment 1

[0044] like figure 1 Shown, a kind of design method of the visualization system of simulation aircraft of the present invention, comprises the following steps:

[0045] (1) Two PCs are used, one PC runs Matlab / Simulink software, and the other PC runs FlightGear flight simulator and client software;

[0046] (2) Among them, the Matlab / Simulink software of the first PC runs the dynamic model of the helicopter and the flight controller model, and calculates a large amount of attitude data through real-time calculation; the Matlab / Simulink calculation core integrates the helicopter dynamics The six-degree-of-freedom attitude information calculated by the model solution is packaged according to the UDP protocol, and is sent to the FlightGear visual software of the second computer in real time through the client for display;

[0047] (3) At the same time, the client software running on the second PC can transmit the changed control parameters to the controller module of Matlab / Simu...

Abstract

The invention provides a design method of a visualization system of a simulated aircraft. The design method comprises the following steps: (1) operating Matlab / Simulink software on one set of PC (Personal Computer) and operating a Flight Gear flight simulator and client software on the other set of PC; (2) operating a dynamic model and a flight controller model of a helicopter in the Matlab / Simulink software of the first PC; calculating and sending a calculated result to Flight Gear visual software of the second computer in real time and displaying; and (3) enabling the client software operated on the second PC to act on the dynamic model by transmitting changed control parameters to the controller model of the Matlab / Simulink software through an RS232 protocol control module, so as to form a whole visualization loop. A lot of long-term tests and verification of the design method provided by the invention show that the operation stability is good and the utilization effect is good.

Description

technical field [0001] The invention relates to the technical field of aircraft control, in particular to a design method of a visualization system for simulating an aircraft. Background technique [0002] The development of helicopters has a history of more than 100 years. Its superior low-altitude performance such as vertical take-off and landing, hovering, and side flight, as well as its uncompromising high-altitude and high-speed performance leave other aircraft in the dust. Helicopters are suitable for performing various tasks under different weather conditions and complex ground environments, and have been widely used in combat, transportation, patrol, rescue and other fields. Helicopter technology has become an important part of aviation high technology and has been paid attention to by countries all over the world. The study of helicopter flight performance and the evaluation of flight quality are indispensable and important links in the process of helicopter develo...
