摘要
在航母甲板上引入斜坡跑道,使舰载机弹射冲程结束后,前轮单独进入斜坡跑道,从而使飞机抬头。建立了舰载机起飞时的简化分析模型,给出了基于该分析模型的运动微分方程及相关参数的表达式,并采用龙格库塔算法对舰载机在斜坡跑道上滑跑起飞这一过程的动态响应进行了数值仿真。仿真结果表明,斜坡跑道的引入可以明显降低舰载机离舰后航迹的下沉量,降低舰载机的离舰速度,增加起飞质量,增大前起落架载荷。
The ramp profile is introduced to the aircraft carrier to make it sure that the nose landing gear goes to the ramp profile after the catapult process,so that the nose of the aircraft rise.The simplified model of the whole carriered-aircraft during the process of catapult take off is built.Dynamic equations about catapult run phase are presented.The dynamic response of the carriered-aircraft during the process of catapult take off is calculated via Runge-Kutta procedure.The results indicate that the introduction of ramp profile can decrease the flight path sinkage during the catapult take off,the off-carrier velocity of the aircraft,and increase the take off masses and the load of the nose landing-gear.
