摘　　要：在弹射起飞的过程中,舰载机的起飞的安全性与多种因素有直接的关系,如剩余甲板长度,前起落架的突伸能力,弹射的冲程等。为了研究多种因素对舰载机弹射起飞的影响,建立了考虑航母纵摇的舰载机弹射起飞动力学模型,分析计算了不同因素对舰载机离舰下沉量的影响,并论述了其运动学成因。研究结果表明:①弹射冲程增大,离舰末速度增大,下沉量减小,反之亦然;②在弹射滑跑转自由滑跑时,前起落架的突伸能力越好,迎角的增量越大,离舰后的下沉量越小,反之亦然;③剩余甲板的长度越长,舰载机离舰的速度和离舰迎角越大,下沉量越小,反之亦然。During the process of catapult takeoff,the safety of carrier based aircraft takeoff is directly related to various factors,such as the remaining deck length,the protruding ability of the front landing gear,and the stroke of the ejection.In order to study the effects of various factors on the catapult takeoff of carrier based aircraft,a dynamic model of carrier based aircraft catapult takeoff considering carrier pitch was established.The influence of different factors on the amount of carrier based aircraft sinking was analyzed and calculated,and its kinematic causes were discussed.The results show that,with the catapult stroke is increasing by,the speed of take-off is increasing and the sinking is decreasing;During the catapult-assisted take-off run transfer to take-off run,the better the ability of the nose gear fast-extension,the greater the increment of the angle of attack,the smaller the amount of the sinking;With the residual deck length is increasing by,the speed and angle of attack of take-off are increasing and the sinking is decreasing.
