摘要
关于单兵多功能供电系统中风机叶片的可靠性问题,为了保证设计质量,选择单兵多功能应急供电系统中风机叶片的翼型(NACA4409和NACA4412)进行分析,并选取了合适的翼型,采用基于贝茨理论,利用几何变换及计算机仿真的方法,运用profili软件获得叶型各截面的初始参数,经坐标变换后得到了三维坐标,并进行分析,得到了扭曲叶片的三维实体模型。仿真结果表明,单兵多功能应急供电系统中风机叶片的整体设计具有低风速启动和整体重量轻的特性,是一种可行的设计方案。
In this paper, individual function of emergency power supply system of fan blade airfoil （ NACA4409and NACA4412） was analyzed in order to ensure the design quality about the multi function power supply system on individual fan blade reliability problems. We selected the right wing based on Bates theory, used the geometric transformation and the method of computer simulation, and the profili software to obtain the initial parameters of each section of the leaf, and finally obtained the three - dimensional coordinates. The analysis was carried on to obtained the twisted blade 3 - D solid model. The simulation results show that individual function of emergency power supply system for fan blade design has the characteristics of starting at low wind speed and light weight, which is a feasible design scheme.
