摘　　要：针对应用电磁弹射器的舰载机弹射起飞过程,综合考虑了电磁弹射器的推力、舰载机前起落架突伸力和载舰的运动,建立了舰载机弹射起飞的数学模型,并据此,分析了上述各种因素对舰载机弹射起飞安全性的影响,计算得到在满足舰载机弹射起飞安全准则的条件下,各种起飞因素应该满足的适应范围。研究分析表明：在风浪较大的恶劣天气条件下,通过适当地增加电磁弹射器的电磁推力和前起落架的突伸力,可以有效抑制舰载机的航迹下沉现象,确保舰载机的安全起飞过程。Taking into consideration the thrust force of electromagnetic launch system,the nose gear fast-extension force and the ship motion process,a mathematical model of a carrier-based aircraft using electromagnetic launch system during the catapult takeoff process was built.Based on the proposed model,the influence of the above factors on catapult take-off safety was analyzed.Moreover,the scales of several take-off factors which accord with the catapult take-off safety were computed.The results indicated that properly increasing the thrust force of electromagnetic launch system and enhancing the nose gear fast-extension force could help to decrease the flight path sinkage and guarantee the catapult take-off safety of the carrier-based aircraft under the condition of atrocious weather.
