将敏感元件,象姿态控制系统那样,直接固联在飞行器上以简化惯性导航系统的前景一直在吸引着研究人员。多年来,人们都把注意力集中在惯性稳定平台上。今天惯性平台在军事、宇宙飞行器以及最近在商用飞机上的应用已经成熟。如果以利用先进的计算机与微电子技术的计算方法来代替机电稳定技术,就可以得到低重量、低成本与高可靠性的捷联系统。这样,人们的兴趣定会转到捷联技术上来。本文评论了捷联法的一些概念与问题,以及近几年在计算机、敏感元件与系统方面的理论与硬设备的进展。应当指出,捷联系统在宇宙飞行器上的应用已经取得了初步的成功,因为在这些飞行器中减重是最重要的,而对精度要求却不高。由于在宇宙飞行器中应用成功,拟将捷联系统用作运载火箭(对环境要求较高)的第二代设备。文章列举了扩大应用的要求和简单描述了包括技术途径与飞行试验的雷锡恩公司的捷联技术计划。
Researchers have been attracting researchers to attach sensitive components, such as attitude control systems, directly to the aircraft to simplify the prospect of an inertial navigation system. Over the years, people have focused their attention on the inertia stabilization platform. Today’s inertial platforms are mature in military, spacecraft and more recently in commercial aircraft. If the use of advanced computer and microelectronic technology to replace the calculation of electromechanical stability technology, you can get low weight, low cost and high reliability of the strapdown system. In this way, people’s interest will go to the strapdown technology. This article reviews some of the concepts and problems of the strapdown method, as well as advances in the theory and hardware of computers, sensitive components and systems in recent years. It should be noted that initial success has been achieved in the application of the strapdown system to space vehicles, where weight loss is paramount but less precise. Due to its successful application in space vehicles, it is proposed to use the strapdown system as a second-generation equipment for launch vehicles, which require high environmental requirements. The article outlines the need to expand the application and briefly describes Raytheon’s Strap technology program that includes technical aids and flight tests.
