Research On Aircraft Engine Fuel Control System For Stage Combustion

As people’s environmental awareness increasing，the engine of civil aviation alsorequires the development of high efficiency, low pollution, sustainable. The engine ofdouble annular combustor matches with the requirements of the development, so thisarticle designs a kind of fuel control system for this combustor, and uses AMESimsimulation software to verify the feasibility and optimal design for this system.First of all, the distribution ratio is got by the analysis for fuel distribution of doubleannular combustor. Modeling and parameter calculation of fuel distributor are based onthis ratio. Secondly, according to the calculation model, the AMESim simulation model isdesigned, and then robustness, dynamic and static are analyzed in different status for thismodel. Parameter optimization design is based on the result of simulation in order torevising and improving model. Furthermore this article expects a physics experimentplatform for distributor and designs a kind of distributor experimental system. Finally, byanalyzing the fuel coke mechanism, a number of measures to prevent the fuel coke areproposed.Through comparing simulation results and raw data, the validity of the model isverified. Parameters of optimized design improve the accuracy of the model, so that atheoretical support for the design of the distributor is provided. The design ofexperimental platform provides a reference for future experimental verification of thedistributor. The measures of preventing fuel coke improve the accuracy of the fueldistributor at working.
