考虑舰面纵摇的舰载机弹射起飞动力学分析

Dynamics analysis on carrier-based aircraft take-off considering carrier pitching

针对舰面纵摇运动对舰载机弹射起飞过程影响较大的问题,根据舰面纵摇特性建立舰载机弹射起飞动力学模型;分析计算不同纵摇初始相位角对舰载机弹射起飞性能的影响.研究结果表明,舰面纵摇改变舰载机离舰时的速度、下沉量和攻角等.为保证飞行安全,需要确定安全弹射起飞的纵摇初始相位角的范围.

As to the greater effect of carrier pitching on the catapult take-off process of carrier-based aircraft, a catapuh take-off dynamics model of a carrier-based aircraft is built according to the carrier pitching characteristics; the effect of different initial pitching phase angles on carrier-based aircraft takeoff is calculated and analyzed. The results indicate that the pitching changes the velocity, sinking and attack angle of aircraft while the aircraft leaves from cartier. The initial pitching range should be determined to ensure the safety of catapult launch take-off. flight path phase angle
