摘要

本文主要研究轻型运动飞机电风扇的初步设计。与活塞发动机相比，电动机的使用带来了一些优势，特别是体积小，动力与轴转速无关。采用一维可压缩流体流动模型来确定其性能。分析了系统各参数的影响。以UL-39超轻型飞机为例，给出了结果。最后根据分析结果确定风机设计的输入参数。然后，这可以用作标准风扇(轴流压缩机)设计程序的输入数据。

Determination of fan design parameters for light-sport aircraft

This paper is focused on the preliminary design of an electric fan for light-sport aircraft. Usage of electric motors brings some advantages compared to piston engines, especially small size and the independence of power on shaft RPM. A 1D compressible fluid flow model is used for the determination of the performace. The influence of various system parameters is analysed. Results for the case of the UL-39 ultralight aircraft are presented. Finally, input parameters for the fan design are determined according to this analysis. This can be then used as input data for the standard fan (axial compressor) design procedure.

期刊介绍： Acta Polytechnica is a scientific journal published by CTU in Prague. The main title, Acta Polytechnica, is accompanied by the subtitle Journal of Advanced Engineering, which defines the scope of the journal more precisely - Acta Polytechnica covers a wide spectrum of engineering topics, physics and mathematics. Our aim is to be a high-quality multi-disciplinary journal publishing the results of basic research and also applied research. We place emphasis on the quality of all published papers. The journal should also serve as a bridge between basic research in natural sciences and applied research in all technical disciplines. The innovative research results published by young researchers or by postdoctoral fellows, and also the high-quality papers by researchers from the international scientific community, reflect the good position of CTU in the World University Rankings. We hope that you will ﬁnd our journal interesting, and that it will serve as a valuable source of scientiﬁc information.
