考虑弹射起飞的航母剩余甲板长度研究

Analysis of deck edge distance taking into account the catapult launch

为了分析弹射行程结束之后剩余甲板长度的范围问题,建立了一种考虑舰载机前起落架突伸作用的弹射起飞动力学模型。对甲板弹射起飞阶段的动力学过程进行了仿真分析,从前起落架突伸作用的角度设计了最有效剩余甲板长度;对离舰起飞阶段进行了仿真分析,从舰载机下沉量的角度设计了最小剩余甲板长度。最后综合考虑前起落架突伸作用和下沉量,提出了一种剩余甲板长度设计方法,并得到了仿真结果的验证,具有重要的现实意义和工程价值。

In order to study the range of deck edge distance after the catapult launch,the dynamics model of catapult launch is constructed considering the fast-extension of the nose gear. The dynamic process of the catapult launching on the deck is simulated and the most effective deck edge distance is designed considering the role of fast-extension of the nose gear. The take-off from the aircraft carrier is also analyzed and the minimum deck edge distance is chosen with respect to sink over the bow. The method of designing deck edge distance is proposed taking into account both the fast-extension of the nose gear and sink over the bow and it is validated in the catapult launch simulation. The research has practical significance and engineering value.
