Design and Experimental Investigation of Anti-surge System for Turbofan Engine

Based on the aerodynamic instability characteristics of a turbofan engine,the engineering mathematical model of turbofan engine stall/surge characteristics was developed.A digital simulation platform of the engine anti-surge system was constructed.The optimizing design of the anti-surge system scheme was completed and verified on the ground and flight test bed.The engineering mathematical model of aerodynamic instability,the optimizing design technology of the digital simulation and the method of test verification were applied widely in the measurement and control of aerodynamic instability for aeroengine,land-based and marine gas turbine,and other civil turbo machinery.And it laid a solid technical foundation for the formulating the design specifications of the turbofan engine anti-surge system.
