为了分析舰载机弹射起飞过程中飞机纵向过载问题，在建立了弹射预紧阶段静力模型、弹射滑跑阶段的动力学模型、自由滑跑阶段动力学模型、航母弹射器模型的基础上，提出了舰载机弹射起飞纵向过载动力学模型。以某型飞机和弹射器为例，搭建仿真框图进行仿真计算并给出了飞机纵向过载与冲程的曲线，通过对仿真结果的分析以及与试验数据的比较，能够为蒸汽弹射系统设计提供有价值的参考。
Abstract
In order to research the longitudinal overload of carrier airplane when aircraft catapult takeoffing from carrier's deck,the carrier-based aircraft longitudinal overload dynamics model is proposed on the basis of establishment of ejection stage preload static model,dynamics modal of catapult run stage,the dynamics modal of shipboard run stage and carrier catapults model.A simulation diagram is built by study a certain carrier-based airplane and a certain catapult and the curve of longitudinal overload and catapult stroke is drawn out.The simulation results which are compared with test data provide a valuable reference for the design of carrier-based airplane catapult system.
