介绍一套用于发动机进气流量管流量校准的缩比模型实验装置。该装置以一定的比例模拟航空发动机试车间结构,设计了进气段、流量段、风机段等系统,设计的缩比模型实验装置进气道速度上限为100 m/s,进气流量15 kg/s。
A set of reduction model experimental device for calibrating the flow of engine inlet flow tube is introduced. The device simulates the structure of the aeroengine test shop with a certain ratio. The system of intake section, flow section and fan section is designed. The experimental design of the reduction ratio model has a maximum inlet velocity of 100 m / s and an inlet flow of 15 kg / s.
