由我院压缩机教研室研制的后置导叶翼型斜流式风机获得我国首批审定的发明专利,国家专利局1985年9月10日公布了这一专利权。 后置导叶翼型斜流式风机是根据三元流动理论和假想等价速度三角形的概念进行设计的,同时,利用NACA65系列叶栅资料完成叶片翼型的几何造型设计。它是一种介于轴流风机和离心风机之间的新型风机,因而具有轴流式大流量和离心式高压力的特点,在比转速70～130范围内,具有明显的高效率和低噪声的优点。具体技术指标为:
The post-guide vane airfoil flow fan developed by the Compressor Department of our institute was granted the first batch of validated invention patents in China. The State Patent Office announced the patent right on September 10, 1985. The rear guide vane airfoil flow fan is designed according to the concept of ternary flow theory and hypothetical equivalent velocity triangle. At the same time, the geometry design of the airfoil is completed by using NACA65 series cascade data. It is a new fan between the axial fan and the centrifugal fan, which has the characteristics of axial flow and centrifugal high pressure centrifugal force in the range of 70 ~ 130, with obvious high efficiency and low noise The advantages. Specific technical indicators are:
