摘要:
格宽翼弦比是影响栅格翼气动特性的一个重要几何参数。为研究它对栅格翼气动特性的影响规律,本研究采用风洞实验的方法对3种不同格宽翼弦比的栅格翼在亚、跨、超声速3个马赫数下进行了气动特性的研究。结果显示,在所选择的格宽翼弦比范围内,格宽翼弦比对阻力的影响不大,对法向力有明显的影响,格宽翼弦比越小法向力特性越好。
Abstract:
The width to width rat io of grid fin was an important parameter influencing the aerodynamics of grid fins. In order to research the aerodynamic characteristics of grid fins effected by width to length ratio, the grid fins of three hight to width ratios were adapted in wind tunnel experiments at subsonic, transonic and supersonic speeds. The results show that the drag of grid f ins is little affected by width to chord rat io, the normal force of grid fins was large, and that the smaller was the ratio, the better was the characterist ics of the grid fins. s normal force in tested sizes of width to chord ratios.
