Tests have been made on a large four-engined flying boat (Solent Mk. 3), to determine the hydrodynamic performance in sheltered water and in open-sea swells. The sheltered water characteristics were investigated over a ...
This report describes an investigation into the hydrodynamic qualities of a Sunderland flying-boat hull, weight 50,000 lb, fitted with a main-step fairing of fairing ratio 17 : 1. The fairing was equipped with ventilating ...
Summary. This report gives further experimental results for compressible turbulent boundary layers with air injection. The experimental arrangement is similar to that used by Jeromin (R. & M. 3526) but, by a slight ...
The wind-tunnel tests on cambered gothic wings reported in Reports and Memoranda No. 3211 have been extended to include the effects of changes in design lift coefficient and of changes in spanwise camber without changes ...
Transient pressures have been measured on the upper surface of a narrow delta wing when it passed through newly sharp-edged upward and downward gusts. Some characteristics of the transient behaviour of the vortex flow on ...
A comprehensive simulation of a slender-wing supersonic transport aircraft during approach and landing has been flown by a number of pilots from airlines and test establishments. The aim of the simulation was to obtain ...
An axially-symmetrical supersonic fully-expanded jet of diameter 0.75 in. was investigated by pitot- and static-tube traverses in the region from the exit to 100 diameters downstream. The investigation is supplementary to ...
The present work was undertaken in order to extend the existing experimental information on the 30 per cent. Griffith suction aerofoil obtained by Richards, Walker and Taylor (1945), in particular: (a) to investigate the ...
Compact devices attached to structures for the remote measurement of displacement and strain, utilising pneumatic principles, have potential advantage in long term creep-fatigue conditions, or at very elevated temperature. ...
The design of a turbine stage is considered on the basis of free vortex flow from the nozzles and blades and some of the factors which limit the design of an efficient turbine stage are discussed. As the flow conditions ...
The effect of a flexible, geared, elevator tab upon the validity of the stiffness criteria for tail-units and rear fuselages is examined. To this end, the distortions of a hypothetical, semi-rigid tail-unit under the air ...
A general method (requiring the aid of a digital computer) is described for deriving the influence coefficients of any type of wing, and hence for evaluating its strength and stiffness characteristics. The method allows ...
Summary. A study of steady lift interference effects in wind tunnels with several different wall conditions has been carried out using a three-dimensional resistance network. The methods by which the various boundary ...
