| Abstract: |
| Objective To verify the performance change of a landing gear after a rapid and severe change of ambient temperature from －55 ℃ to normal temperature in the progress of aircraft diving form high altitude to landing and taxiing. Methods High and low temperature environment simulation techniques for aircraft landing gear were researched according to requirements on drop test of landing gear. Results Special high and low temperature simulation equipment for landing gear was successfully developed in view of indicators on test techniques and restrictions on structural size of test piece and test site. Conclusion It provides a method for verifying change rules of sensitive parameters and temperature in the buffer of the landing gear and the structural performance of the landing gear. |
