基于轴流压气机级特性 ,建立了带燃烧室的多级轴流压气机过失速的一维逐级分析模型 ,发展了分析轴流压气机过失速响应的动态滞后方法 ,确定了压气机过失速响应的统一时间常数。并将该模拟技术应用到某压气机中 ,通过调节收敛喷嘴面积和燃烧室燃油流量等措施来诱导压气机失速。压气机旋转失速后 ,压气机流量下降 ,增压能力降低 ,燃烧室温度升高 ,可以通过调节燃油流量等措施来使压缩系统恢复正常工作
Based on the characteristics of axial flow compressor stage, a one-dimensional step-by-step analytical model of stalling speed of multi-stage axial flow compressor with combustion chamber was established. The dynamic lag method of analyzing the over stalling response of axial flow compressor was developed. Uniform time constant of stall response. The simulation technique was applied to a compressor to induce the compressor stall by adjusting the area of the converging nozzle and the fuel flow in the combustion chamber. Compressor rotation stall, the compressor flow rate decreased, reducing the pressure increase, the combustion chamber temperature can be adjusted by adjusting the fuel flow and other measures to make the compression system to resume normal operation
