3m×2m结冰风洞云雾参数校测方法
Cloud calibration method of 3m× 2m icing wind tunnel
摘要
Abstract
The cloud calibration has been carried out under SAE ARP5905 standard for 3m × 2m icing wind tunnel,results of which can be used for certificating icing wind tunnel performance and supplying data proof for obtaining icing flight certification.Based on the ice accretion mechanism,the phase doppler interference principle,and the hot-wire principle,the calibration work was completed in the main test section by using the icing grid,PDI-FPDR,the icing blade,and LWC-200.Methods and procedures are summarized to increase the efficiency of calibration.Typical cloud calibration results indicate that the icing cloud uniformity is good,60 ％ of the main test section could remain target LWC within ±20％.The MVD maximum deviation is smaller than ±10％.The LWC stability is greater than ±20％.All the cloud parameters could meet the requirements of ARP5905,which could be used for supplying data proof of 3m× 2m icing wind tunnel certification.关键词
