Centrifugal fans are an important part of the oil cooling system for a high-performance helicopter

Centrifugal fan is an important part of high-performance helicopter oil cooling system, which drive the cold air through the oil cooler, took over the transmission system cooling oil heat, ensure the normal operation of helicopter main reduction system.  Instrumentation ball valve  fan performance the quality of the oil radiator as well as the efficiency of the entire oil system plays a vital role as an engine oil cooling system components helicopters, centrifugal fan with low flow, high pressure, high speed, small size Features This article based on the characteristics of a  Instrument valve manifold  a fan, a detailed analysis of the design parameters of the basic structure and calculation, blade profile, the preparation of the versatility of the design software, the use of technology to achieve the automatic generation of the impeller three-dimensional graphics, and gives the design instance.
