摘要
探讨舰面运动（舰面纵摇、横摇和沉浮运动）对舰载飞机弹射起飞特性的影响。数值分析表明，舰面纵摇可使飞机离舰后最大下沉量增大较多，是舰面运动中最危险的因素。通过适当选择预置升降舵偏角、增大油门、增大航空母舰前进速度、减轻起飞质量和限制起飞时舰面最大纵摇角等方法可较大地抑制飞机下沉。舰面沉浮和横摇对飞机离舰后最大下沉量影响比纵摇为小。但横摇使飞机离舰前滑跑困难，离舰后产生横侧振荡，飞机出现较大的航向偏角。利用算例飞机自身的控制系统可较快地抑制飞机振荡。舰面运动还使起落架振动加剧。在舰载飞机设计和使用条件方面必须考虑舰面运动的影响。
This paper deals with how the deck motion(longitudinal oscilla-tion,lateral oscillation and heaving oscillation)affects the catapult-assisted take-off characteristics of the carrier based airplane,The numerical analysis indicates that the deck longitudinal oscillation can create the maximum sink of the airplane,there-fore the longitudinal oscillation is the most dangerous factor of the deck motion.The sink can be inhibitted by the given elevator pre-setting,increasing the take-off properly choosing speed,decreasing take-off weight and limitting deck maximum longitudinal oscillation amplitude. Though,both deck heaving and lateral oscillation have less effects on maximum sink,lateral oscillation will make take-off run difi-cult,cause airplane lateral oscillation and more yaw. It can be seen from some exam-ples of calculation that the airplane oscillations can be easily damped by using the airplane’s own automatic control systems.Besides,the deck motion also makes gears oscillation more serious. Therefore,the effects of the deck motion must be considered in designing and appling the carrier based airplane.
