舰载飞机与航母之间的参数适配特性是弹射起飞总体方案设计阶段的关键问题之一.针对舰面起飞的复杂环境,建立了舰载飞机弹射起飞的数学仿真模型.在此基础上,分析了各主要机舰参数对弹射起飞安全性的影响,并计算得到满足弹射起飞安全准则的主要机舰参数的适配值集合.研究结果表明:在弹射起飞过程中,增加弹射能量、前起落架突伸力和升降舵预置偏角均可抑制航迹下沉;在适配值集合内,随着弹射能量的增加,升降舵预置偏角的适配范围增大,前起落架突伸力的影响减小.

The parameter match between a carrier-based aircraft and the aircraft-carrier is one of the key issues in the conceptual design phase of catapult takeoff. A mathematical simulation model of a carrier-based aircraft during the catapult takeoff process is built up taking into consideration the complicated takeoff environment. Based on the model, the influence of primary aircraft-carrier parameters on catapult takeoff safety is analyzed and the match value set of primary parameters that accord with the catapult takeoff safety criteria is computed. The results indicate that enhancing the catapult energy, the nose gear fast-extension force and presetting the elevator angle can help to decrease the flight path sinkage during the catapult takeoff process. Within the boundary of the match value set, as the catapult energy increases, the match range of the presetting elevator angle enlarges and the influence of the nose gear fast-extension weakens.
