- W2390725758 abstract "To improve the take-off performance of carrier-based aircrafts,the fast-extension performance of the nose landing gear of a carrier-based aircraft is optimized by controlling the process that the cross-section area of damping oil-hole of oleo-pneumatic buffer with two-stage shock absorber changes with the stroke. A mechanical model is built for the fast-extension motion of nose landing gear using the two-mass-spring-damping system,the function on the changes of the cross-section area of damping oleo-hole with the stroke is substituted into the fast-extension motion differential equation,and the mathematical model is established to optimize the fast-extension time. The displacement curves and velocity curves of the optimized fast-extension motion are obtained by the golden section optimization method. The curves are compared which are obtained from three sets of damping oleo-hole with different constant section area under the same structure parameters and initial filling parameters. The result shows that it is rational to use the damping oil-hole with variable cross-section area to optimize the fast-extension performance of the nose landing gear of carrier-based aircraft." @default.
