This is the second of the two extreme cases listed at the start of the last section. Highly loaded aircraft withlow aspect ratio wingsflying at high altitudes will tend to conform with the motion described in this section. The equation for the rolling moments is(11.29)with the damping in ro...
Numerical Simulation of a High-Aspect-Ratio Wing Using High Fidelity Aero-Structural Coupled Method High-aspect-ratio wings, with the inherent nature of maximizing the lift-to-drag ratio, have been widely employed in modern airplanes. However, highly flex... ZH Wang,MY Lv,JH Meng,... - 《...
A numerical analysis is performed to study the flow around low-aspect-ratio (LAR) wings and more particularly the resulting lift-and-drag force. The research is focused on low-Reynolds-number aerodynamics, as LAR wings are crucial for the development of microa r vehicles (MAWs). The How aro...
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...
Wind tunnel tests were conducted on low aspect ratio wings in order to: (1.) Measure the oscillatory aerodynamic lift forces, pitching moments, and hinge moments acting on rectangular wings of aspect ratio 1 and 2, due to the harmonic vibration of flap or tab; (2.) Measure similar data ...
Therefore, it is concluded that CVPs play an important role in mitigating the flow separation for wings with leading-edge tubercles. 展开 关键词: Leading-edge tubercles Low-aspect-ratio Flow separation DOI: 10.1016/j.taml.2022.100386 年份: 2023 ...
The design of micro aerial vehicles requires a better understanding of the aerodynamics of small low-aspect-ratio wings. An experimental investigation has focused on measuring the lift, drag, and pitching moment about the quarter chord on a series of thin Rat plates and cambered plates at chord...
An investigation was made in the Langley 24-inch high-speed tunnel to determine the effect of leading-edge shape and section profile on the aerodynamic characteristics of two thin wings of aspect ratio 4. Lift, drag, and pitching-moment data are presented for a range of angle of attack from...
