Title The measurement of Jet engine performance parameters
Abstract Turbojet engine is not only has low fuel consumption as well as structure and manufacturing process is relatively easy, but also has high thrust-weight ratio advantage and is well able to meet the power demand of small aircraft, such as the unmanned aerial vehicles, cruise missiles and missile patrol, so the micro gas turbine engine attracts increasingly widespread concern. In the combustion chamber of micro gas turbine engine, temperature, pressure, speed of gas has an important effect on engine performance. It is necessary for the testing test to ensure all the micro gas turbine engine performance indicators in line with requirements of the material environment as well as it could work properly and efficiently. This dissertation mainly includes the design and installation of the bench, selection of test methods and the overall design of the test platform as well as the analysis of the experimental data of micro gas turbine engine, and finally exam the performance of micro gas turbine engine for the next optimization .
Keywords micro turbojet engine, temperature, pressure, speed of rotation

1 引言 1.1 研究背景及其国内外发展现状 随着现代战争和科学技术的发展、自动化能力的增强，世界各国在军事领域都纷纷研制各种各样的无人设备，巡飞弹、靶机、无人机、以及其它各类微小型飞行器等。这些无人设备在恶劣环境下反恐、导弹战略攻击、空战、军事及其民用侦察等方面已经越来越显示出不可忽视的优势 [1-5]。例如在伊拉克战争中，美国的“全球鹰”侦察机、“捕食者”歼击机发挥了不可估量的作用[6]。 除军事应用外, 微小型飞行器在民用上也发挥出其独特的作用。已经广泛的运用在防汛抗旱、电力抢修、救灾物质投送、通信中继、监测边境监控、调查野生动物、监测土地资源、调查矿产资源开发调查与监视、铁路建设勘测等领域，具有良好的经济效果及技术优势都非常看好。在缉毒缉私、边境巡逻、治安反恐等方面也有很好的应用前景[6]。 1.2 国内外微型涡喷研究进展 1
