Compressor Research Based on Aeroengine Product Requirements

The compressor is an essential component of an aeroengine. With the increasing requirements of advanced combat aircraft on aeroengines, it is a major challenge for compressor designers to quickly develop a compressor that fully meets aeroengine product requirements. To ensure that the compressor can fully satisfy aeroengine product requirements, typical characteristics of advanced combat aircraft engines and comprehensive technical requirements for compressors are reviewed, and key influencing factors for the compressor to meet aeroengine product requirements are presented. Research of design methods was conducted, including high efficiency in wide rotational speed range, high stall margin across the full flight envelope, high performance-retention capability, highly reliable blade, highly robust compressor rotor, highly reliable blade angle adjusting mechanism, high safety, and high environment adaptability. The research shows that the requirement-based comprehensive design can ensure the comprehensive performance of the compressor, providing a refer? ence for the design of a compressor that fully meets aeroengine product requirements.
