Three-dimensional Measurement Point Processing and Accurate Calculation of Throat Area for Aircraft Turbine Nozzles
Turbine nozzles were crucial components in aircraft engines,and the throat area was a key parameter that directly affected the engine's power performance.In response to the issues of low efficiency and inaccurate estimation in existing measurement methods for the throat area,a new meth-od for three-dimensional measurement point processing and accurate calculation of the throat area for aircraft turbine nozzles was proposed.Comparative experiments between the proposed method and the CMM method were conducted on a multi-blade turbine nozzle sample.The experimental results show that the throat areas obtained by the proposed method are more accurate,and the results of multiple measurements and calculations have high consistency.
