The compressor blades of aero-engines are the key components for aero-engines to generate thrust through gas. The R&D and manufacturing of high-temperature turbine blades involves complex technologies such as precision casting, thermal barrier coating, and film hole processing.
China’s leading manufacturer of aero-engine compressor blades: WXHY Aerospace Technology Corporation, due to its own production needs, has independently developed an integral blisk double-axis CNC pressure shot peening machine. The shot peening machine can blast glass pellets with a diameter of 0.3 mm to At a speed of 20 million pieces per minute, the spray gun hits the blades of the aero-engine compressor, forming a layer of 0.1 mm compressive stress on the surface of the blades, increasing the service life of the overall blades by 10 times.
The blisk and blade surface strengthening technology is recognized globally as a major technical problem for aero engines. The blisk double-axis numerical control pressure shot peening machine successfully developed by WXHY has made new breakthroughs in this field.
About WXHY
WXHY is a specialized enterprise that develops and produces aero engine compressor blades with precision forging manufacturing technology; blades produced by precision forging technology have always been aero engine compressor blade manufacturers due to their high reliability, high performance, and high efficiency. At present, more than 90% of the world’s aero engine compressor blades are produced using precision forging manufacturing technology.
The company has successfully developed the aero engine compressor blades for LEAP series of Safran and GE (this engine is the mainstream engine type in 150-seat single-aisle passenger aircraft such as French Airbus A320, American Boeing 737, and COMAC C919), CFM56 series, CF34 , CF6, PP20, LMS100, LM9000 and other compressor blades, covering more than 50 stages of blades.
As of the end of 2020, the company has delivered more than 1.3 million compressor blades to Safran and GE Aviation; at the same time, it has also participated in the high-pressure and low-pressure compressors of China's high-performance engines and the domestic CJ-1000/CJ2000 engines of C919/CR929 large aircraft. The task of blade development.
