在某型涡扇发动机气动失稳特征的基础上,建立了航空发动机失速/喘振特征工程数学模型,研制出发动机消喘系统数字仿真平台,完成了消喘系统的方案优化设计,并在地面台架和飞行台试验中得到了验证。其气动失稳工程数学模型、数字仿真优化设计技术和试验验证方法可广泛应用于航空发动机、地面和舰船燃气轮机、以及其它民用叶轮机械气动失稳测控设计领域,同时也为制定航空发动机消喘系统设计规范奠定了坚实的技术基础。
Based on the aerodynamic instability characteristics of a turbofan engine, a mathematical model of aeroengine stall / surge characteristic engineering is established, a digital simulation platform for the engine anti-asthma system is developed, and the scheme optimization design of the anti-asthma system is completed. Bench and flight test has been verified. The aerodynamic instability engineering mathematical model, digital simulation optimization design techniques and experimental verification methods can be widely used in the field of aerodynamic instability measurement and control of aero-engines, ground and ship gas turbines, and other civilian impeller machinery, and also for the development of aeroengine anti-asthma System design specifications laid a solid technical foundation.
