A control-surface oscillatory derivative rig for use with half-models in high-speed wind tunnels

K. C. Wight; N. C. Lambourne (1976)
The effect of sweepback on the fundamental derivative coefficient for flexural motion

J. B. Bratt; K. C. Wight (1950)

Measurements have been made with new equipment designed for derivative tests in a 9 x 7 ft tunnel, to determine the effect of sweepback on the derivatives for a rectangular aerofoil of aspect ratio 6. Some difficulty was ...
An experimental investigation of wall-interference effects on dynamic measurements on half-models in ventilated tunnels through the transonic speed range

A. W. Moore; K. C. Wight (1967)

Summary. Results are presented of an experimental investigation of ventilated-wall interference on dynamic measurements using half-models in four transonic tunnels, three of which have a slotted roof and floor whilst the ...
An experimental investigation of wind-tunnel wall conditions for interference-free dynamic measurements

A. W. Moore; K. C. Wight (1969)

Results are presented of dynamic tests on two model half-wings performing pitching oscillations in the NPL 24 cm x 24 cm (9½ in x 9½ in) tunnel. The boundary condition at the ventilated roof and floor is varied by fitting ...
Measurements of control-surface oscillatory derivatives on a sweptback, tapered model wing in two transonic tunnels

N. C. Lambourne; K. C. Wight; B. L. Welsh (1976)

Results of measurements of control-surface oscillatory derivatives on a sweptback, tapered half-model of a lifting surface of aspect ratio 2 are presented. The measurements were obtained during the development of a derivative ...
Measurements of the direct oscillatory derivatives for a linear bending mode on four rigid half-span models at subsonic and transonic speeds, in closed and slotted tunnels

K. C. Wight; J. A. Nixon (1963)

Measurements have been made of the direct damping and stiffness derivatives for four rigid half-span models oscillating in a linear bending mode about an axis near the root in high-speed wind tunnels. A Mach number range ...
Measurements of two-dimensional derivatives on a wing-aileron-tab system with a 1541 section aerofoil. Part 1 direct aileron derivatives

K. C. Wight (1952)

Measurements have been made of the direct two-dimensional damping and stiffness derivatives for a 20 per cent aileron on an aerofoil with a 1541 section in incompressible flow. Corrections arising from the apparatus are ...
Measurements of two-dimensional derivatives on a wing-aileron-tab system with a 1541 section aerofoil. Part 2 direct tab and cross aileron-tab derivatives

K. C. Wight (1955)

Measurements have been made of the direct tab derivatives and cross aileron-tab derivatives for a 1541 section two-dimensional aerofoil (N.P.L. 282) with a 20 per cent aileron and 4 per cent (approx.) tab. In addition some ...
On achieving interference-free results from dynamic tests on half-models in transonic wind tunnels

A. W. Moore; K. C. Wight (1969)

Under review
The theory of interference effects on dynamic measurements in slotted-wall tunnels at subsonic speeds and comparisons with Experiment

H. C. Garner; A. W. Moore; K. C. Wight (1966)

Summary. Experiment has already shown that the aerodynamic damping on half-span models in pitching oscillation is subject to interference effects that may exceed 30 per cent in slotted-wall tunnels at subsonic speeds. An ...
