Method for measuring air flow of turbine blade machined holes

Abstract

The invention relates to a method for measuring air flow of turbine blade machined holes. The method comprises the following steps: step A, square yellow wax with side length of 10 mm or more is pressed into a double cone shape, and the distance between two cone tips is from 3 mm to 6 mm; step B, the double cone-shaped yellow wax produced in step A is pressed into a blade tip slot, so that the blade tip slot is filled with the yellow wax; step C, plugged turbine blades in step B are placed in a thermostat while maintaining blade tips upwards, the temperature of the thermostat is adjusted to 50DEG C, and the plugged turbine blades are taken out after being heated for 30 seconds to 60 seconds and then placed in a constant temperature of 20 DEG C for about 20 minutes, so that the yellow waxis completely cooled and solidified; step D, flow measurement is performed; step E, the yellow wax in the turbine blades is removed to complete the measurement. The method can be used for directly measuring flow data of a back cavity machined vent hole, thereby effectively ensuring measurement accuracy.

AI Technical Summary

Benefits of technology

This patented technology allows us to accurately determine how well two parts are doing together when they work properly without any mistakes from converting them into another form or adding extra components like holes on their surface.

Problems solved by technology

This technical problem addressed in this patents relates to improving the efficiency and durability of aerospace engines' (a type of aircraft) aerodynamic vane used during flight operations such as takeoff or landing. To improve these properties, certain materials like ceramic fiber reinforced plastic ("CFRP") may be added into the interior space between two layers called chambers. These components help distribute the loadings evenly throughout the entirety of the component while maintaining sufficient coolant flows within specific areas. However, current techniques require multiple steps before reaching steady conditions, leading to increased time delays and decreased reliability.
