AI Technical Summary

Technical Problem

Traditional compressor blades with fixed geometry are difficult to achieve efficient and stable power output under multiple operating conditions. Existing research on flexible blades is immature, with complex structures and difficult deformation to achieve and control, thus failing to meet design requirements.

Method used

An adjustable flexible compressor blade is designed by setting a sliding support frame and a flexible blade skin between the inlet and outlet frames. The blade shape is changed by moving the support frame. Continuous smooth deformation is achieved by combining graphite/epoxy resin composite materials and various adjustment and locking components.

Benefits of technology

It improves the efficiency and aerodynamic stability of the compressor, adapts to complex flow field environments, meets the aerodynamic efficiency requirements of a wider range and harsher operating conditions, reduces fatigue load, increases lift coefficient, and ensures service life.
