Description

technical field [0001] The invention relates to a water flow measurement device and method for turbine cooling blades of a gas turbine. Background technique [0002] In the design of aero-engines and ground gas turbines, with the continuous development of science and technology, the temperature in front of the turbine is also increasing, which not only depends on the improvement of the process level, but also requires the improvement of the structural design, so the cooling of the turbine blades The design and cooling effect tests are also being continuously improved. Its patent number is 02280657.1, which is a device for detecting the water flow of turbine blades, which is used for the cooling test of aeroengine turbine blades. Compared with the aeroengine turbine blades, there is a big difference between the ground gas turbine blades and the aeroengine turbine blades. The gas turbine blades are especially Turbine cooling blades of heavy-duty gas turbines have large blades...
