Research on the pressure peak of landing gear uplock opening for civil aircraft

摘要

This paper do a research on the pressure peak of landing gear uplock unlocking for civil aircraft. This paper first do a theory analysis and find out relevant factors like valve opening time, tube length, tube diameter and a restrictor. Then based on the AMEsim platform, a simulation model is built. From the simulation results, it can be known that the valve opening time, tube length, tube diameter and a restrictor all can have an obvious effect on the uplock pressure peak. An optimize solution is found after a trade-off analysis.
