Physical bench test research on coordinated steering of main wheel for civilian wide-body aircraft

With the development of civil aircraft to large size and super-large, the use of main wheel coordinated turning control technology is an important guarantee to improve its ground operation capability, safety and airport adaptability. In order to fill the technical gap faced by our country, a physical test verification research method of coordinated turning of main wheels is proposed, according to the design index of coordinated steering of main wheels, the system integration builds the physical principle prototype test environment and carries out the directional working condition test, Result shows that the trend of the landing gear torque and lateral force results under the coordinated steering meets the expectation.
