2.To investigate viscous flows around low-aspect-ratio wings of a micro-aerial vehicle(MAV) at low Reynolds numbers,experiments are conducted in a wind tunnel using particle image velocimetry(PIV) and a smoke wire technique.应用粒子图像速度场仪(PIV)和烟线两种流动显示技术,测量低雷诺数下小展弦比...
In response to this need, a study of the lift, drag, and pitching moment characteristics of wings of low aspect ratio operating at low Reynolds numbers are presented. Wind-tunnel tests of wings with aspect ratios between 0.5 and 2.0, four distinct planforms, thickness-to-chord ratios of &...
A combined computational and experimental analysis was performed on a tangent ogive body with verylow aspect ratio wingsin the ‘+’ (plus) orientation at Mach numbers 0.1, 0.2 and 0.3, with the aim of developing a database of global force and moment loads. Three different span to body diam...
The flow over a planar low-aspect-ratio delta wing is considered in the strong viscous-inviscid interaction regime. The study is carried out for Newtonian passage to limit, when the adiabatic exponent tends to unity, while the Mach and Reynolds numbers increase without bound. For the flow over...
The unique aerodynamic regime of low aspect ratio (LAR) wings is strongly affected by the phenomenon of roll stall. In this study, it is shown that roll stall induces inherently aerodynamic stability modes on a flat plate wing with an aspect ratio of unity. These modes are seen to create ...
In this study, an experimental investigation of a low aspect ratio rectangular membrane wing with excess length was presented at angles of attack ranging f... Serdar Gen,Mustafa - 《Experimental Thermal & Fluid Science》 被引量: 60发表: 2013年 Roll Stall for Low-Aspect-Ratio Wings. The longi...
3.Neural network control in active vortex control based onlow aspect ratio flying wing;以小展弦比飞翼布局飞机为研究对象,其本体的优化增稳控制器由3个气动舵面(连续控制面)构成。 英文短句/例句 1.Qualities Assesses Criterion of Short Period Mode for Flying Wings with Low Aspect-Ratio小展弦比飞翼构...
Results of an experimental investigation on echelon formations using low-aspect-ratio (AR = 2) flat plate rectangular wings at low Reynolds number (Re 35;000) are presented. One-, two-, and three-wing configurations are tested in a low-speed wind tunnel. To quantify the power savings by ...
A wind-tunnel investigation has been conducted to determine the effect of ground proximity on the aerodynamic characteristics of thick highly cambered rectangular wings with aspect ratios of 1. 2, 4, and 6. The results showed that, for these aspect ratios, as the ground war, approached all wi...
A numerical design study has been conducted to ascertain the potential of winglets as a drag-reducing measure at high subsonic Mach numbers for low aspect ratio wings. The four variants of the winglet concept studied are a 'detuned' wing... JM Kuhlman,MJ Cerney,P Liaw 被引量: 1发表: 1988...
