Stability of Symmetric and Asymmetric Vortices over Slender Conical Wing-Body Combinations
نویسندگان
چکیده
Theoretical analyses of the stability of symmetric and asymmetric vortex pairs over slender conical wing-body combinations consisting of a slender circular or elliptic cone and a flat-plate delta wing under small perturbations in an inviscid incompressible steady flow at high angles of attack with or without sideslip are presented. The three-dimensional flow problem is reduced to a problem in two dimensions, for which a general stability condition for vortex pairs can be applied. The stationary positions of symmetric and asymmetric vortex pairs and their stabilities are examined for various geometric configurations, angles of attack, and sideslip. Results of the analyses are compared with available experimental data and used to help gain insight into the flow behavior.

Stability of Symmetric and Asymmetric Vortex Pairs over Slender Conical Wings and Bodies
Theoretical analyses are presented for the stability of symmetric and asymmetric vortex pairs over slender conical wings and bodies under small perturbations in an inviscid incompressible flow at high angles of attack and sideslip. The three-dimensional problem of a pair of vortices over slender conical wings and bodies is reduced to a problem in two dimensions by using the conical flow assumpt...
متن کاملExperimental Investigation of Asymmetry of Vortex Flow Over Single Delta Wings
It is generally believed that, on slender delta wings, there is a critical state at which strong asymmetric vortices are found along the leading edge on the lee-side of the delta wing. These asymmetric vortices can lead to high lateral forces even when slender delta wing is at the zero angle of yaw. Some experimental studies reported recently, cast considerable doubt as to the validity of the a...
متن کاملStability of Vortex Pairs over Slender Conical Bodies: Analysis and Numerical Computation
A N INITIALLY symmetric vortex pair over a slender pointed body or wing–body combination, such as that shown in Fig. 1, becomes asymmetric as the angle of attack is increased beyond a certain value, causing large rolling moments in the case of swept wings or large side forces in the case of slender bodies, even at zero roll and yawing angles. At even larger angles of attack, unsteady vortex she...
متن کاملDesign of Optimal Wing–Body Configuration to Delay Onset of Vortex Asymmetry
O NE important phenomenon associated with high-angle-ofattack aerodynamics is the sudden onset of vortex asymmetry on the forebody of an air vehicle in symmetric flight. One of the first observations of the onset of vortex asymmetry was reported in 1951 by Allen and Perkins [1]. Interest in the phenomenon has been intensified since the late 1970s as concepts for highly maneuverable aircraft hav...
متن کاملEffect of Wing Sweep Angle on the Vortex Interaction of a Tail-Wing Configuration
The goal of this investigation is to study the effect of wing sweep angle on the horizontal wing-body- tail configurations in subsonic flow. For this purpose, a series of wind tunnel tests were conducted on a model having a moveable horizontal tail and a wing planform with different sweep angles. Tests were performed at different tail deflection angles. Static surface pressure distribution over...
