过去二十年来,空军火箭推进实验室(AFRPL)在固体火箭发动机部件和推进剂性能评定用的标准化试验发动机与实验室设备的研究方面,作了大量工作。这些标准化装置使用方式多种多样,但总体上可分成两大类,即用在测量与判别性能、数量、内容、范围、数值、质量等方面的引证根据和比较基础两大类。标准试验发动机和实验设备均具备下列特性,即重量大;可重复使用;多种用途;在共同设施中试验;工作程序固定;内部型面不变。
Over the past two decades, the Air Force Rocket Launch Laboratory (AFRPL) has done a great deal of work on standard test engine and laboratory equipment for the evaluation of solid rocket engine components and propellants. These standardized devices are used in a variety of ways, but in general they can be divided into two categories, that is, two types of evidence-based and comparative basis for measuring and discriminating performance, quantity, content, range, value and quality. Standard test engines and laboratory equipment have the following characteristics, namely, heavy weight; reusable; a variety of purposes; test in a common facility; work procedures fixed; internal profile unchanged.
