【摘要】 由于海上风浪与能见度等环境因素的影响,使得舰载直升机归航着舰难度增加,安全作业保障成为突出问题,因此,在夜间或低能见度条件下直升机着舰引导的机舰适配性研究显得尤为重要。本论文从提高直升机着舰引导机舰适配性出发,以法国研制生产的直升机着舰引导装备——下滑横摇指示系统为研究对象,对其系统功能、组成以及基本工作原理进行了重点介绍,并对该系统存在的引导光束混杂问题和横摇信息指示模糊问题进行了深入分析,探讨解决上述问题的有效技术途径。首先,通过对舰船运动引起的下滑引导光束空间位移的定量计算,以及对传统的点稳定控制方法的效果分析和局限性讨论,提出了下滑指示器的改进方案。下滑指示器采用凸透镜与凹透镜相结合的直筒式结构形式,并引入旋转与直线相结合的位移补偿机构对下滑引导光束的空间位移进行补偿,解决了下滑引导光束的混杂问题。其次,横摇指示器采用垂直基准灯杆与固定灯杆组合、运用LED阵列控制灯具的改进方案,引入舰船运动预报技术,设计了直升机甲板降落时机预报法,从而有效地解决了横摇角信息指示模糊问题。最后,以下滑横摇指示系统的实船安装位置数据为基础,运用ADAMS软件对下滑指示器改进方案的运动补偿机构功能,横摇指示器改进方案的垂直基准功能进行了仿真,验证了机构的可行性。本论文为有效提高直升机着舰引导的机舰适配性,从上述三方面进行探索研究,为研制新型的下滑横摇指示系统积累了经验,提供了新的思路和方法。更多还原

【Abstract】 Because of influence of the circumstance factor such as wave and visibility, the difficulty of guiding carrier helicopter landing on deck has increased, and working security become a significant problem. Therefore, the adaptation study about landing guide of the carrier helicopter at night or low visibility appeared especially central.In this paper, in order to improve the adaptation about landing guide of the carrier helicopter, the gliding and rolling instructed system is studied, the system’s function、form and basic working theory are introduced thoroughly to discuss the beam mixed problem and the reason of rolling information faint problem that exited, and the effective approach of solving those problems.Firstly, the improve scheme is raised by quantitative calculation of the space movement of gliding indicate beam and discussion of the limitation of the traditional method—point stability. The light mixed problem was solved by the adoption of the straight canister structure form convex combined with concave mirror and by imported displacement make up framework of revolute linked with straight in gliding instructor. Secondly, rolling information faint problem was utility settled by improve scheme that adopted perpendicularity reference integrated with fixed light-pole and LED light, and by designed helicopter landing time prediction approach that imported ship motion prediction technic. Finally, based on the data where gliding and rolling instructor setted, ADAMS is used to model and emulation.In order to improve the adaptation about landing guide of the carrier helicopter effectively, calculating the experience to newly gliding and rolling instructed system from studing on the three parts upside, at the same time, provide the new train of thoughts and methods.更多还原
