Modeling and Performance Analysis of Augmented-fuel Metering Unit for Turbofan Engine

Augmented-fuel metering unit of aeroengine is very important to the accurate realization of the control law of augmented-fuel and the performance of afterburner light-on and cutting off process. In order to analyze the performance of augmented-fuel metering unit of turbofan engine, the simulation model of augmented-fuel metering unit was established by the object-oriented modeling software AMESim. The deep analysis of the dynamic performance, the anti-interference ability, the realization of command pressure and the function of reverse cutting fuel of the unit was conducted. The results show that the performance of the augmented-fuel metering unit can achieve the design requirements. The models provide a reference for the design, the improvement and modification, performance optimization of the augmented-fuel metering unit.
