摘要/Abstract

摘要： 为研究航空发电机匹配风扇设计的实用性方法，通过相应的实验装置，对某型航空发电机进行了风阻特性实验。通过强迫通风实验测得发电机不同状态下的风阻、流量及温升，根据实验结果及该发电机设计要求，利用正交设计方法设计出一种宽弦、大转折角、高稠度的轴流冷却风扇，同时设计了特殊的扩张轮毂结构，以进一步提高冷却性能。对加装设计风扇的发电机进行实验，验证了该风扇适用于该发电机冷却系统的高压差、小流量工况。

Abstract: In order to study the practical method of aeronautic generator cooling fan matching design, the wind resistance of an aeronautic generator was measured by the relevant experimental equipment. Through one forced air ventilating experiment, wind resistance, flow rate, and temperature rise of the generator under different working conditions were measured. According to the experimental results and design requirements of the generator, the orthogonal design method was employed to obtain a cooling axial-flow fan with wide chord, big turning angle, and high pitch ratio. Meanwhile, a specially expanding hub was designed to further enhance the cooling performance. The test of generator installed with fan shows that the designed fan meets the demands of aeronautic generator cooling system which is suitable for the high pressure rise and small flow rate working conditions.

Key words: air generator, cooling system, wind resistance experiment, cooling fan design
