ABSTRACT |
The auxiliary blower system is one of the parts needed to achieve transonic flow in the NAL 2m×2m Transonic Wind Tunnel.This system was replaced in 1990~1992.The reconstructed blower is the 8,000 kW axial compressor with adjustable stator blades.Theredy,the blower controls aspirate itself in the air from the perforated test section.During the replacement,efforts were made to increase its energy efficiency,to simplify the total system,and to accomplish the automa |
