摘　　要：详细介绍了FL-3风洞喷流、带涡轮动力模拟器(TPS)试验中用于流量和压力控制的数字阀系统的设计,包括技术指标、总体方案、通断阀门的类型和喷管的气动设计等。地面调试结果表明:数字阀系统设计合理,喷流流量绝对控制精度小于±5g/s,且控制时间快、效果平稳,满足了FL-3风洞喷流、TPS试验流量压力精确快速控制的设计指标。The technical target ,the scheme,the type of valve and the design of nozzle for the design of the digital valve system used to controll mass flow and pressure are introduced in this paper for power simulation testing in FL-3 wind tunnel.The experimental results show that the measuring accuracy of mass flow and pressure control is ＆#177;5g/s respectively for the digital valve system,and the digital valve also has the advantages of quick and stable control.The digital valve system can satisfy the demand of accurate control of the flow rate and pressure for aircraft power simulation testing in the FL-3 wind tunnel.
