基于AMESim的热气防冰系统笛形管设计与仿真

Design and Simulation of Piccolo Tube of Hot Air Anti‑icing System Based on AMESim

笛形管是飞机热气防冰系统的重要组成部分,笛形管上的孔径、孔间距以及笛形管的引气入口参数决定了防冰供气流量的大小及分配,从而影响防冰性能。本文基于多学科系统建模仿真平台AMESim,建立了笛形管流量分配仿真分析模型,对机翼热气防冰系统笛形管结构参数进行迭代设计。设计参数包括笛形管管径、喷孔孔径及孔间距等参数,最终获得了能够平衡设计状态点防冰热载荷的结构参数和引气流量分配,得到了防冰系统的引气压力制度。本文提出的基于AMESim的笛形管迭代设计方法可为热气防冰系统中笛形管的设计与优化提供参考。

The piccolo tube is an important part of the aircraft hot air anti-icing system.The diameter and spacing of the holes on piccolo tube and the inlet pressure of hot air determine the amount and distribution of the supplied anti-icing hot air,thus affecting the anti-icing performance.Based on the multi-disciplinary system modeling and simulation platform AMESim,the flow distribution simulation model of piccolo tube is established,and the structural parameters of piccolo tube of wing hot air anti-icing system are iteratively designed.The design parameters include diameters of piccolo tube,orifice diameter and spacing.After several iterations,the values of structural parameters and bleed air flow distribution that can balance the anti-icing thermal load at the design state point are obtained.Furthermore,the pressure schedule of bleed air for the antiicing system is determined.The proposed iterative design method of piccolo tube based on AMESim can provide reference for the design and optimization of piccolo tube in hot air anti-icing system.
