冲压发动机地面试验技术及试验能力述评

Review of ramjet ground-test facilities and relevant technology development

分析了试验气体加热技术、变马赫数试验技术以及光学测量技术等冲压发动机地面试验关键技术的发展趋势,梳理了美国、俄罗斯、日本、法国以及中国等国家的主要冲压发动机地面试验设施运营管理机构,并对典型试验设施的能力进行了介绍。通过梳理分析国外冲压发动机地面试验技术发展趋势和试验能力现状,指出了我国冲压发动机地面试验能力和技术与国外存在的差距,对我国冲压发动机地面试验能力建设和技术发展方向提出了建议。

In this work,the development trend of ramjet ground-test technologies,such as tested gas heating,varying Mach number and optical measuring techniques were analyzed.The capacities and its operation and manager institutes of some typical facilities in USA,Russia,Japan,France and China were combed systematically.Based on the analysis of the abroad ground-test facility capacities and relevant technology development trend,we pointed out the gap between our country with other developed countries,and proposed some suggestions on the test capacity promotion and technology development.
