An application of fast frequency-sweep excitation to the measurement of sub-critical response of a low speed wind tunnel model

C. W. Skingle; D. R. Gaukroger (1976)

The application of the hilbert transform to system response analysis

C. W. Skingle; K. H. Heron; D. R. Gaukroger (1977)

Body freedom flutter of ground-launched rocket models at supersonic and high subsonic speeds

D. R. Gaukroger (1957)

A theoretical investigation of symmetric body freedom flutter of a rocket model is described. The results confirm that structural failures of models were caused by this type of flutter, and an extension of the investigation ...

Comparative flutter tests on two, three, four and five-blade propellers

H. G. Ewing; J. Kettlewell; D. R. Gaukroger (1948)

This report describes comparative flutter tests on two, three, four-and five-blade Duralumin propellers with the same blade design. The tests were made on the No. 3 spinning tower, Royal Aircraft Establishment. Straingauges ...

The development of rapid-testing techniques for flutter experiments

K. W. Newman; C. W. Skingle; D. R. Gaukroger (1974)

Flutter characteristics of a wing carrying a flexibly mounted mass

D. R. Gaukroger (1961)

Calculations have been made to investigate the effects on wing flutter of flexibility between a wing and an added mass. Flexibilities in pitch, roll, and yaw have been separately investigated for a mass carried at the tip ...

Impedance measurements on a spinning model helicopter rotor

R. Cansdale; D. R. Gaukroger (1978)

An investigation of wing-aileron flutter using ground launched rocket models

D. R. Gaukroger; J. K. Curran (1962)

Measurements of fluctuating pressures in and behind the bomb bay of a Canberra Aircraft

C. W. Skingle; N. M. Willcox; D. R. Gaukroger (1968)

The spectra of pressures at points in and behind the bomb bay of a Canberra aircraft have been obtained for a range of flight conditions. The primary objective of the flight measurement programme was to acquire data for ...

Measurements of oscillatory aerodynamic hinge moments from the response of a wind tunnel model to turbulent flow

G. B. Hutton; D. A. Drane; D. R. Gaukroger (1975)

Natural frequencies and modes of a model delta aircraft

D. R. Gaukroger (1950)

Resonance tests on a model delta wing are described. Consideration is given to the effect of inertia distribution on the first three normal symmetric modes of vibration. The mean centre of gravity position, fuselage pitching ...

A preliminary experiment in resonance testing a rotating blade

C. W. Skingle; D. R. Gaukroger; G. A. Taylor (1969)

An experiment to excite the flapping modes of a two-blade nonarticulated model rotor is described. The experiment was designed to develop a method of exciting a blade whilst it is rotating, and to measure the change of ...

Rolling-power tests on an elastic model wing (M-planform) in low-speed flow

D. R. Gaukroger; J. K. Curran; A. T. Marriot (1962)

Measurements and calculations of aileron effectiveness for an elastic model wing in low-speed flow are described. The experimental technique enabled rolling moments due to applied aileron and to rate of roll to be measured ...

A technique for measuring oscillatory aerodynamic control surface hinge moments from forced response characteristics

D. R. Gaukroger; D. A. Drane; R. Gray (1973)

Wind tunnel tests on antisymmetric flutter of a delta wing with rolling body freedom

D. R. Gaukroger; D. Nixon (1955)

Wind-tunnel flutter tests on a delta wing with an all-moving tip control surface

D. R. Gaukroger (1953)

Wind-tunnel tests on a half-span model delta wing, fitted with an all-moving tip control surface, are described. The model, which is flexible, has a leading-edge sweepback of 45 deg; and the control surface, which is rigid, ...

Wind-tunnel flutter tests on a model delta wing under fixed and free root conditions

D. R. Gaukroger; E. W. Chapple; A. Milln (1950)

Wind-tunnel tests on a model wing of delta plan form are described. Tests have heen made with the wing root fixed and also with the root free in pitch and vertical translation. Critical flutter speed and frequency are given ...

Wind-Tunnel Tests on the Effect of a Localised Mass on the Flutter of a Swept-back Wing with Fixed Root

D. R. Gaukroger (1953)

Wind-tunnel tests to determine the flutter characteristics of a model wing, carrying a localised mass, are described. The investigation covers the effects of wing sweepback, and of the magnitude and position of the localised ...

Wind-tunnel tests on the effect of body freedoms on the flutter of a model wing carrying a localised mass

D. R. Gaukroger; E. W. Chapple (1956)

Wind-tunnel test results for the flutter of a swept-back wing carrying a localised mass, and having symmetric or antisymmetric freedoms of the root, are given. The tests were made on a model wing of 23 deg sweepback, the ...

Wind-tunnel tests on the symmetric and antisymmetric flutter of swept-back wings

D. R. Gaukroger (1953)

Wind-tunnel tests to determine the symmetric and antisymmetric flutter characteristics of a swept-back wing are described. The investigation covers the separate experimental treatment of the symmetric and antisymmetric ...
