Problems solved by technology

[0004] Although these two methods can obtain high-precision cold-state models, the first conversion method can basically guarantee the accuracy of axial flow blades, but it is difficult to guarantee the accuracy of centrifugal impellers and centripetal turbine blades; although the second method has high accuracy However, the amount of calculation is large and time-consuming, and it is difficult to meet the needs of rapid conversion in engineering practice

Abstract

The invention discloses a centrifugal impeller and turbine blade profile cold and hot state rapid conversion method, which mainly aims at the problem of large deformation calculation amount of control points of each modeling cross section of a blade profile in an iteration process, comprehensively considers aerodynamic load, temperature field and centrifugal load, and calculates the cold and hot state of the blade profile by calculating the deformation of a mean camber line of each modeling cross section. And carrying out linear interpolation to obtain deformation of each modeling section control point. Therefore, the conversion precision is ensured, and the problem of large calculation amount of a deformation output point can be solved.

Description

technical field [0001] The invention relates to the technical field of design of a centrifugal impeller and a turbine blade, in particular to a method for quickly changing the cold and hot states of a centrifugal impeller and a turbine blade. Background technique [0002] After the aerodynamic design of the centrifugal impeller compressor or turbine of the engine is completed, the given flow passage and airfoil are the hot state dimensions of the design point, and the parts processed according to the design model should be cold state models. If processed directly according to the thermal model, the centrifugal impeller compressor or the turbine rotor will be deformed in the working state, especially the turbine rotor will be significantly deformed under aerodynamic load, high temperature and centrifugal load, and these deformations will affect the aerodynamic performance of the component , performance that deviates from the design point. [0003] Existing conventional metho...
