Study of Post Stall Control during Turbofan Engine Startup Based on Correlative Dimension

Considering the correlative dimension of the pressure inside compressor is sensitive to engine stall,the control of the starting post stall of turbofan engine based on correlative dimension was investigated.The examples show that the post stall during turbofan engine startup can be controlled through ascertaining the occasion of the turbofan engine's post stall from the correlative dimension of the pressure inside compressor and adjusting the fuel flux of combustor at engine starting.
