Optimization of the parameters of landing gear systems with double-stage air springs of catapult take-off carrier-based aircraft is here studied based on the mathematical equations of the classic dual mass spring-damper dynamic model.Certain standards for both take-off and landing performance are put forward.The contradictory factors between take-off and landing processes are analyzed.The optimization of oil in the pin area and the area near the rear oil hole is performed.Then these optimized parameters are used to assess the influence of the initial pressure of the low chamber,the ratio of the high chamber to the low chamber,and the tire inflation pressure on the performance of arresting landing and catapult take-off.The influences of these parameters on carrier-based aircraft and the aircraft-carrier on aircraft catapult take-off is also assessed.Based on the results of the simulation,respective take-off criteria must be drafted considering different types of aircraft and different take-off load cases,all of which must be matched to parameters relevant to catapult take-off.

The optimization of oil in the pin area and the area near the rear oil hole is.Then these optimized parameters are used to assess the influence of the initial pressure of the low chamber, the ratio of the high chamber to the low chamber, and the tire inflation pressure on the performance of arresting landing and catapult take-off. These influences of these parameters on carrier-based aircraft and the aircraft-carrier on aircraft catapult take-off is also suitable. Based on the results of the simulation, each take-off criteria must be drafted review different types of aircraft and different t ake-off load cases, all of which must be matched to parameters relevant to catapult take-off.
