摘　　要：本文深入地研究了实现轴流风机直接反转反风的可行性,采用独创的新翼型,用最优控制理论优化设计了一种新型风机模型,并进行了试验研究。理论研究与实验表明,该风机结构简单、调节方便;可直接反转反风,而正反风性能相近;与现有风机比较,其反风性能大大提高,为轴流风机的反风技术开创了一条有极大实用价值的新途径。The inverse ventilation of axial-flow fan by simply reversing the motor is studied in the paper. Using a new-type airfoil and optimal control method, an axial-flow fan model has been designed and made. The experimental data are shown to be in good agreement with the calculated ones. The features of the new-type fan are its simple construction, convenient control and better reverse ventilating char- acter. It can ventilate inversely by simply reversing the motor and has the same characteristics as those of normal ventilation.
