| Abstract (English): |
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 method 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 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.
