METHOD for the stress analysis of the circular conical fuselage with flexible frames, subjected to a fairly general type of load distribution, was recently developed by the present writer in a paper published in the Journal of the Royal Aeronautical Society. This paper did not, however, make any...
THE paper by Thompson, Wadsworth and Louat on The Origin of Fatigue Fracture in Copper contains much valuable information which, together with other recent work of the same nature, affords a basis for reviewing various theories concerning the mechanism of fatigue. In the light of recent...
Sandwich construction with aluminium honeycomb cores bonded to faces with the adhesive films Redux 775, 775R and Bloomingdale FM47 is discussed. Drawings showing its applications to a series of components for various hypothetical aircraft arc included. Sandwich materials for supersonic aircraft...
WHEN selecting alloys for use in structures whose life would be limited by fatigue, the choice is greatly aided by consideration of fatigue tests on simple testpieces in which the effects due to stressraisers, fretting, temperature, etc., are dealt with under idealized conditions.
The pressure control valve is a possible means of overcoming the effects of compliance between a hydraulic servo and its load. The valve consists of two stages an opencentre flow control valve schematically analogous to a resistance bridge, and a splitslider valve. In order to study the dynamics...
This is a reprint of a book that was first published in 1932. As there has been no revision of the contents since the original publication, no work done in the last twentyfive years is included. Nevertheless, the book includes a considerable amount of material that is still of interest.
Under this heading are published regularly abstracts of all Reports and Memoranda of the Aeronautical Research Council, Reports and Technical Memoranda of the United States National Advisory Committee for Aeronautics and publications of other similar Research Bodies as issued.
Angula Engineering Co. Ltd., Glaskin Mews, Pembury Road, Clapton, London, E.5 have introduced a straightedge of new construction for the drawing board. As shown in FIG. 1 the ruling edge is of clear Cobex, gripped in an aluminium alloy extrusion, to which a mahogany rail is attached. It is...
In order to procure a sequence of superimposed still photographs showing the tumbling or gyrations of a pilot's ejection scat, a droppable fuel tank, or bombs after release from a model in a wind tunnel, Chance Vought Aircraft, Inc., have developed a simple technique. Small scale models were...
The blades 16 of a torquecompensating rotor for a helicopter are connected by a pair of parallel flexible steel strips 28 which are arranged to be substantially undeflected when the blades are at their maximum pitch setting. By this means as the pitch is reduced the twist set up in the strips 28...
