航空发动机燃油阶跃试验供油规律
Fuel supply law of aero-engine fuel spiking test
摘要
Abstract
In order to analyze the influence of fuel supply law of aero-engine in the fuel spiking surge test,a hybrid exhaust turbofan engine with a small bypass ratio was taken as the research object.The engine was modeled as a typical system composed of essential components and built an equilibrium equation considering the rotor dynamics equation and volume effect.The fuel spiking surge process of the engine was simulated.The error between the simulation result and experimental data was within 4%,which verifies the accuracy of the calculation method.The key influencing factors of the step fuel supply law were obtained through the simulation.The simulation results can provide a theoretical basis for the fuel spiking test of the engine and reduce the risk of overtemperature and overturning during the fuel spiking surge process,which has certain engineering significance.关键词
