本文为英国皇家空军学院(RAFC)的一份研究生学位论文,原文作者系澳大利亚空军的 K.M.FORREST。本文讨论了空空导弹的几种控制方法及它们在“敏捷”(一种无翼外形的小型空空导弹)空空导弹上的应用。具体分析了两维情况下的比例导引(PN:Proportional Navigation)和加速度矢量导引(AVN:Acceleration VectoredNavigation)规律,并且得到了它们相应的仿真形式。进而利用矢量代数研究了三维交会的导引规律。讨论了与“敏捷”导弹有关的大攻角气动力现象,并考虑了它们对飞行器动力学的影响。在若干简化与假设条件下,可以以最少的数据进行导弹弹道仿真。用开发的计算机程序对推力矢量控制(TVC:ThrustVector Control)空空导弹进行了仿真:假定导弹具有二阶响应滞后,导引头能提供目标运动的理想无噪声信息,实际上对交会的初始几何关系没有限制,而且考虑了目标的躲避机动。文末附有仿真计算的程序框图。本文对空空导弹总体设计的基本技术问题,都在研究文献的基础上分别作了论述,主要有:控制技术、制导技术、空气动力学、动力学、三维交会分析、导弹特性、目标模型、交会参数、大气模型等。其中分析归纳得比较好,或研究方法较有新意的章节,更具参考价值。因此,从本期起分几次将译文选择刊出,供利用。因系选刊,除必要的技术处理外,章节号没作改变,基本上保持了原文面貌。
This article is a post-graduate dissertation by the Royal Air Force Academy (RAFC), original author of K.M.FORREST, Australian Air Force. This article discusses several control methods for air-to-air missiles and their use in “agile” air-to-air missiles. The laws of Proportional Navigation (PN) and Acceleration Vectored Navigation (AVN) in two dimensions are analyzed in detail, and their corresponding simulation forms are obtained. Then the vector algebra is used to study the guiding law of the three-dimensional intersection. The aero-dynamics at high angles of attack related to Agile missiles were discussed and their effects on aircraft kinematics were considered. Under a number of simplifications and assumptions, missile trajectory simulations can be conducted with a minimum of data. Simulation of Air-to-Air Missile with Vector Control (TVC): With the second-order response lag of the missile, the seeker can provide the ideal noise-free information of the target movement. In fact, the initial geometric relationship of the intersection There is no limit, but also consider the goal of avoiding maneuvering. End of the text attached to the simulation of the program block diagram. In this paper, the basic technical issues of the overall design of air-to-air missiles are discussed on the basis of the research literature, including: control technology, guidance technology, aerodynamics, dynamics, three-dimensional intersection analysis, missile characteristics, the target model, Parameters, atmospheric model and so on. Which analysis is better summarized, or research methods more innovative section, more reference value. Therefore, several translations have been selected for publication since this issue. Because of the Department of election, in addition to the necessary technical processing, the section number has not changed, basically maintained the original appearance.
