Aerodynamic performance of Parastoo UAV
Aircraft Engineering and Aerospace Technology, 2013PurposeThe purpose of this paper is to investigate the flow around Parastoo UAV's wing, with the aim of improving its aerodynamic performance. A major source of concern is the use of relatively large flaps in the original design. This unmanned aerial vehicle (UAV) operates at low Reynolds numbers of below 500,000 and was designed for short‐range ...

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.

High-Performance-Rotor Aerodynamic Testing
Proceedings of the Vertical Flight Society 73rd Annual Forum, 2017A whirl and wind tunnel test was conducted to measure performance and stall vibration benefits associated with a novel Retreating Side Blowing (RSB) concept, Miniature Trailing edge Effectors (MiTEs), and Lateral Lift Offset (LLO) trim. A new 28 ft diameter rotor mounted to an articulated S-76R rotor hub was flown at the National Full Scale ...

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 ...

AC75 Aerodynamic Performance Prediction via BEM
Journal of Sailing TechnologyAbstract The AC75 class, used in the America’s Cup, is a hydro-foiling racing sailing yacht powered by a double-skin main sail and a single-skin jib. The boat performance is typically predicted by a Velocity Prediction Program (VPP). The aerodynamics are usually modeled with surrogate models of data points collected

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.

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.

Turbine Aerodynamic Performance Measurement Under Non-Adiabatic Conditions
Volume 6: Turbo Expo 2007, Parts A and B, 2007The practical performance, both the efficiency and durability, of a High-Pressure (HP) turbine depends on many interrelated factors, including both the steady and unsteady aerodynamics and the heat transfer characteristics. The aerodynamic performance of new turbine designs has traditionally been tested in large scale steady flow rigs, but the testing ...
