Investigation of the Normal Force Characteristics of Slender Delta Wings with Various Rhom bit Cross-Sections in Subsonic Conical Flow

Experimental Investigation of the Positions of the Leadir/g-Edge Vortices above Slender Delta Wings with Various Rhombic Cross-Sections in Subsonic Conical Flow

The positions of the centres of the leading-edge vortices above four slender wings have been located at several angles of incidence using a Kiel tube probe, and measured using a mutual inductance method of &stance measurement. This method was developed for use in this experiment to provide accurate information about the position of a probe in the flow field by measuring the mutual inductances b...

Experimental 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...

A New Simple Analytical Model for Flow Analysis Over Slender Delta Wings

An Assessment of the Accuracy of Subsonic Linearized Theory for the Design of Warped Slender Wings

SUMMARY A series of warped slender wings has previously been designed using the linearized theory of subsonic flow, as a basis for a systematic experimental investigation of the drag reduction obtainable by warp at low speeds. The force measurements on these wings have now been supplemented by measurements of the pressure distribution over one of them; and the pressure distribution on it has al...

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...
