本文介绍了一种推力为100 N的小型航空发动机的研制工作。首先，在试验台架上对一台商用30N型喷气发动机进行了试验研究。基于测量结果，建立了一个计算程序来表示测量结果。然后将计算缩放到100 N推力。在三维CAD系统中进行了缩比发动机的设计，并对选定的零件，主要是涡轮机叶轮进行了应力分析。在发动机部件制造和装配完成后，在试验台上进行了试验，并与预测值进行了比较。
The presented work is concerned with the development of a very small aero-engine with 100 N thrust. First a commercially available 30 N-model jet engine was studied on a test bench. Based on the measurements, a calculation procedure was built to represent the measurements. Then the calculation was scaled to 100 N thrust. The scaled engine was designed in a 3D-CAD system, in which the stress analysis of selected parts, mainly the turbine wheel were performed. After the engine parts were manufactured and assembled, the new aero-engine was tested on the test bench as comparison with the predicted values.Copyright © 2000 by ASME
