摘　　要：为有效预防喘振的发生,确保飞机的飞行安全,设计一种自主飞行飞机喘振自动化控制技术。采用高精度动态压力传感器捕捉并分析脉动压力变化,计算喘振紊流度。采用改进的拉格朗日-欧拉方法,分析飞机在紊流中的动态行为,建立自主飞行飞机喘振运动学模型。通过实时监测和调整飞行姿态与动力输出,避免飞机进入喘振区域,预防飞行性能急剧下降和安全事故的发生。实验结果表明,设计的自动化控制技术,在发动机转速降至75%额定值时,喘振造成的压力波动峰值被显著控制在较低的2.5×10^(4)Pa水平,与实际发动机压力波动率基本一致,展现文章技术在控制喘振方面具有明显准确性。To effectively prevent surges and ensure the flight safety of autonomous aircraft,this study designs an automated surge control technology.High-precision dynamic pressure sensors are employed to capture and analyze pulsating pressure changes,calculating the degree of turbulence associated with surges.An improved Lagrangian-Euler method is utilized to analyze the dynamic behavior of aircraft in turbulent flows,establishing a kinematic model for surge control in autonomous flying aircraft.The concept of surge control margin is introduced,defining the safe distance between the current flight state and the surge boundary,ensuring flight safety.By continuously monitoring and adjusting the flight attitude and power output,the system prevents the aircraft from entering the surge region,avoiding significant declines in flight performance and potential safety incidents.Experimental results demonstrate that the proposed automated control technology effectively controls the peak pressure fluctuations caused by surges at 2.5×10^(4)Pa when the engine speed drops to 75%of its rated value.This result aligns well with actual engine pressure fluctuation rates,highlighting the accuracy and effectiveness of the developed technology in surge control.
