Aerodynamical Improvement of Delta Wing and Flapping Wing
Volume 1A: Symposia, Part 2, 2015Recently, various studies of Micro Air Vehicle (MAV) and Unmanned Air Vehicle (UAV) have been reported from wide range points of view. The aim of this study are researching the aerodynamic improvement of delta wing and flapping wing in low Reynold’s number region to develop an applicative these air vehicle.

Subsonic wing rock of slender delta wings
Journal of Aircraft, 1985Two recent experimental studies investigated the s elf-excited motion Of a flat deita wing that was free to roll about an axis parallel to its mid-span chord. In this paper these experiments are s imulated numerically. An unsteady vortex-lattice method is used to provide the aerodynamic loads, and the equation of motion is integrated by a prediction ...

Buffeting Flows over Delta Wings
AIAA Journal, 1999Experimental evidence suggests that vortex breakdown is not the only source of buffeting of delta wings and fins. Other unsteady flow phenomena that contribute to buffeting at high angles of attack are fluctuations of vortex breakdown location and vortex shedding.

Wing Rock of Nonslender Delta Wings
Journal of Aircraft, 2000That slender delta wings will experience wing rock is an established fact, and the responsible flow mechanism is well understood. However, the same flow mechanism could not cause wing rock of nonslender delta wings. Thus, the wing rock observed for a 45-deg delta wing must be generated by a different flow phenomenon.

2006 International Forum on Strategic Technology, 2006
A numerical analysis of free roll vibrations of a delta wing in an ideal incompressible flow (wing rock) is performed by solving the coupled dynamic and unsteady-aerodynamic equations. A computational algorithm is constructed on the basis of the vortex-lattice method.

Design of a Delta Wing Aircraft
2017 International Conference on Mechatronics, Electronics and Automotive Engineering (ICMEAE), 2017This work shows a UAV (Unmanned Aerial Vehicle) modeling of a fixed wing type and a delta wing configuration. The selection of an aerodynamic profile and the aircraft dimension was chosen. On a CAD package the geometric design was created, where the finite element analysis and fluid dynamics shows that the behavior of the aircraft follows the ...

44th AIAA Aerospace Sciences Meeting and Exhibit, 2006
The paper discusses the topology of the skin -friction line pattern on a 65 -deg swept delta wing with special attenti on to the flow on the apex that usually is poorly resolved in experiments. A large -scale model of the apex was constructed to obtain a better insight into the flow.

A well-known category of flows where Boussinesq’s hypothesis is expected to fail is vortex-dominated flows. Unfortunately, many of the flows of industrial interest involve vortices, such as those emanating from the roof of a car, or from the wing tips of airplanes. The delta wing is another example of a flow where the accurate resolution of the physics

The delta wing in oscillatory gusts
AIAA Journal, 1980This report describes systematic aerodynamic lift and pitching moment measurements on two sharp edged delta wings of aspect ratio 1 and 2 in oscillatory vertical gusts of varying frequency parameter and gust amplitude. The effects of the nonlinearity associated with the separated flow region are explored and the influence of the potential flow and the ...
