Analysis of dynamic characteristics of catapult launch for a carrier-based aircraft with sudden load discharge
摘要
Abstract
In order to study dynamic characteristics of catapult launch for a carrier-based aircraft, a simplified dynamic model of catapult launch with sudden load discharge of nose gear was constructed. Fast vibration in the vertical direction of nose gear caused by the sudden discharge of the holdback load in the beginning of catapult launch was studied, and the dynamic reason of this phenomenon was analyzed. The rules of fast extension of nose landing gear caused by the sudden discharge of the catapult bridle load at the end of catapult launch was researched, and the influence of all parameters on the extension of nose landing gear was analyzed. Two important conclusions were obtained: in order to reduce the vibration peak value of the strain of nose landing gear during catapult launch, the holdback and catapult bridle lengths should be increased appropriately, and the maximum holdback breaking load is suggested to increase properly. Secondly, in order to decrease the difficulties of catapult launch, the catapult bridle length is recommended to decrease moderately.关键词
