Airplane rising, landing and taxiing performance comprehensive verification platform

Abstract

The invention provides an airplane rising, landing and taxiing performance comprehensive verification platform integrating airplane inertia simulation, lateral wind load simulation, taxiing speed simulation, runway state simulation and brake control and very high in universality, and by means of the airplane rising, landing and taxiing performance comprehensive verification platform, all-factor simulation and testing evaluation in the airplane rising, landing and taxiing processes can be achieved. The airplane rising, landing and taxiing performance comprehensive verification platform comprises an aircraft simulation system, an undercarriage airplane system, a braking system, a lateral wind simulation loading system, a runway simulation system, a measurement and control and simulation system and the like. By means of the airplane rising, landing and taxiing performance comprehensive verification platform, the taxiing speed, the course heading, the loading force and the braking torque can be measured, and visual simulation and braking control strategy researches can be conducted as well. The airplane rising, landing and taxiing performance comprehensive verification platform can provide an early-period theory, simulation and experiment basis for active-service or researched aircraft landing gear system design, taxiing control rate design and whole airplane inertia optimal allocation. The problem that at present, the control strategy can only be researched at the test flight taxiing stage is solved, and thus the cost and risks of out-field taxiing tests are greatly lowered.

Description

technical field [0001] The invention relates to a platform for comprehensive verification of aircraft take-off and landing roll performance. Background technique [0002] With the rapid development of modern industry and science and technology and the intricate international situation, major countries have stepped up the development of new aircraft, and our country has also set off a wave of research and development of various types of aircraft. As we all know, the development of an aircraft needs to go through exploration, development, and prototype testing before it can be mass-produced. The development time is very long, especially after the prototype is developed, a large number of ground sliding tests need to be carried out before the take-off and landing test can be carried out. That is because, It only has the ability to test the braking force of the rear wheel of the landing gear and the measurement and analysis of the braking torque, and has a certain technical rese...

AI Technical Summary

Problems solved by technology

The performance test can only be carried out through the roll test before the flight test, which is not only time-consuming and labor-intensive, but also has certain technical risks. It is often impossible to conduct a comprehensive assessment of the ultimate wind resistance and the ability to adapt to complex runway environments, which greatly limits the ability of the aircraft. Improvement and comprehensive evaluation of takeoff and landing performance
