【摘要】 随着海洋争夺战向立体化,多层化发展,各国迫切需要掌握海上制空权,制海权,维护海洋权益,保障领土安全。由于直升机可担负侦察、搜救、运输、反潜、两栖突击、空中预警以及电子战、水雷战等多种使命,因此,世界各国在竞相发展航空母舰和大型舰船的同时,都在大力发展性能优良的直升机。而建立一套完善的直升机船台辅助降落系统是当前迫切需要解决的主要问题。本文针对直升机船台辅助降落问题,设计出了一套确定飞机定位及飞行姿态的方法,并进行了模拟仿真。通过研究本论题的背景和意义和国内外研究的现状,说明研究直升机助降系统的必要性。在直升机助降系统的方案中,主要介绍系统的组成、功能、工作原理,工作流程,和船面的主要设施、降落过程、降落因素等。随后建立直升机辅助降落的数学模型方法,主要论述飞机降落时,确定其位置坐标的方法和飞行姿态,以及飞机飞行中姿态控制原理,偏航控制原理、俯仰控制原理、滚转控制原理及与迎角的关系等。最后,对系统模型进行了模拟仿真,并对其效果进行了简要的评价,分析了系统的优点和存在的不足,指出研究直升机船台辅助降落系统的重要意义。
【Abstract】 With the stereoscopic and multipolar development of modern sea battle, every country need master aeroamphibious right urgently to protect sea rights and interests, guarantee territory safety. AS soon as helicopters are concerned, they can take on a good many tasks, such as spy, search and rescue, transport, antisubmarine, amphibious landing sudden attackair early warning and the electronics wars, the torpedo war etc. various mission, therefore, international community at the time of developing the carrier and other ships competitively, all at develop the good ship of function to carry the helicopter strongly. But at present the main and will be resolved urgently problem is to build up a set of perfect helicopter landing system.This article designs a way for helicopter orient- ion and fly pose, at the same time makes an imitation for test.It introduces background and meaning of this thesis, including native or foreign research actuality, the necessary of the ship helicopter landing system. It introduces a project for ship helicopter landing system, including system composing, function, working theory, working flow, main establishment on board, landing course, landing factor etc. It recommends one maths model way for ship helicopter landing system. It mainly introduces a means for ship helicopter position coordinate and fly pose when it will land. At the same time it recommends fly pose control theory, Yawing-angle control theory, pitching-angle control theory, turn-angle control theory, meet-angle relation when it is flying. At last, it simulates in systems, estimates the effect, make an analysis of the merit and the flaw and points out the important meaning of the ship helicopter landing system.
