中国燃气涡轮研究院(以下简称我院)承担着大量发动机型号研制和预研任务,工厂加工完成的每一个涡轮叶片均需要进行气膜孔流量试验,目的是为判定气膜孔加工是否满足设计需求提供依据。在流量试验过程中,涡轮导向叶片流量试验夹具是一套能在常温环境下检测涡轮导向叶片气膜孔流通能力的密封装置,其密封性能是确保试验有效、测量数据准确的关键。加工工厂由于试验条件限制,往往通过水测量叶片气膜孔流通能力,但这与用空气测量情况并
China Gas Turbine Research Institute (hereinafter referred to as our hospital) undertakes a large number of engine model development and pre-research tasks, the completion of each factory turbine blades are required for film flow test, the purpose is to determine whether the gas-hole machining to meet the design Demand basis. During the flow test, the turbine guide vane flow test fixture is a set of sealing devices capable of detecting the flow capacity of the voids of the turbine guide vane at room temperature. The sealing performance is the key to ensure the test is effective and the measurement data is accurate. Processing factories due to test conditions, often through the water to measure leaf vias flow capacity, but this is measured with the air and
