Performance of an aerodynamic particle separator
Waste Management, 1996Abstract This compact, high-flow device aerodynamically separates small particles from a gas stream by a series of annular truncated airfoils. The operating concept, design and performance of this novel particle separator are described. Tests results using corn starch and post-cyclone coal fly ash are presented. Particle collection efficiencies of 90%

Aerodynamic Design and Performance
Aircraft Engineering and Aerospace Technology, 1965An Outline of the Basic Configuration and Aerodynamic Features of the Argosy including Performance and Flight Handling Qualities. THE basic concept of the Argosy as a medium‐size freighting aircraft with a large capacity fuselage of high cross sectional area and low freight floor defined to a large extent the shape of the aircraft.

The aerodynamic performance of paragliders
The Aeronautical Journal, 1999AbstractAn analysis of paraglider performance has revealed that wing section drag is the most significant contribution to overall drag. Wind tunnel measurements performed on two-dimensional hollow models indicate that intake drag is less significant than previously thought.

Performance of an Aerodynamic Particle Sizer
Applied Occupational and Environmental Hygiene, 1993Abstract In occupational and ambient environments, there is increasing need to monitor the atmospheres in real time so that emission sources are easily identified and exposure episodes can be better understood. Recently, several instruments have been developed commercially for aerodynamic particle-size measurements.

Aerodynamics of High Performance Wing Sails
SNAME 1st Chesapeake Sailing Yacht Symposium, 1974Some of the primary requirements for the design of wing sails are discussed. In particular, the requirements for maximizing thrust when sailing to windward and tacking down wind are presented. The results of water channel tests on six sail section shapes are also presented.

Aerodynamic performance of a winggrid [PDF]
Comprehensive experimental and analytical studies have been conducted to assess the integration of a force balance in a low speed wind tunnel and to measure the performance of a new type of aeroplane winglet called a winggrid. The winggrid is an extension to a wing that utilises a cascade of wings to decrease the induced drag on a wing (La Roche, 2005).

The Aerodynamic Performance of Lotus EMEYA
SAE International Journal of Passenger Vehicle Systems<div>In this article, the aerodynamic features of two configurations of Lotus EMEYA are introduced. The first configuration includes a fixed air dam and an active rear spoiler (ARS) assembly, which has two active blades in order to obtain the aerodynamic drag and lift performance ...

Aerodynamic Performance of Biological Airfoils
2nd AIAA Flow Control Conference, 2004Experimental studies on static, non-flapping dragonfly wings have shown favorable aerodynamic performance at low Reynolds number (Re ≤ 10,000). High lift is hypothesized to arise from the dragonfly’s pleated wing structure. A numerical study of flow past a modeled dragonfly wing section as well as its comparison to a corresponding profiled airfoil and ...

The improvement of aerodynamic performance
2017Since the collapse of the first Tacoma Narrows Bridge in 1941 much research has been focussed on the design of road decks that are secure against wind action. This paper reviews the development of aerodynamically stable deck configurations and the use of devices for improving the performance of large bridges as either retrofits or in original design ...
