PurposeThe purpose of this paper is to optimize the downrange for hypersonic boost‐glide (HBG) missile under near‐real condition, and to validate the suitability of proposed wall cooling materials.Design/methodology/approachThe tr...... hiện toàn bộ
The mechanism of stress formation in glass under‐going conditions of rapid cooling, and the factors affecting the properties of the toughened glass produced are discussed. The application of techniques for measuring the temperature of glass, to the control and study of the toughening process are described.
FOR aerofoils intended for use at high speeds, it is evident that the maximum lift on the back, consistent with a given maximum intensity of suction, will be attained when the suction, and hence the velocity, over the back is uniform; in other words, for a given mean lift on the back, the greatest suction will be a minimum, and so will the greatest velocity. On the hypothesis that compress...... hiện toàn bộ
The world's first helicopter AEW (Airborne Early Warning) squadron has been formed by the Royal Navy in a commissioning ceremony at RNAS Culdrose, Cornwall, today (November 9).
The effect of moncyclic versus polycyclic aromatic components in JP‐5 fuels, on total flame radiant energy was investigated. Variations in aromatic type and content within the JP‐5 specification had an effect on flame radiation. Polycyclic aromatic fuel blends burn with higher flame emissivities than the monocyclic blends of comparable ASTM Smoke Point. Radiant heating of metal parts was s...... hiện toàn bộ
In a supersonic aircraft, a fuselage, a plurality of aerofoils fixed relative to said fuselage including top and bottom surfaces, said aerofoils being longitudinally spaced from the centre of gravity of said aircraft, means for selectively creating supersonic aerodynamic wave patterns over a major portion of said aerofoils whereby differences in pressure result between the top and bottom s...... hiện toàn bộ
Leading manufacturers and their suppliers have begun to reap the benefits of a radically new way of bringing products to market. As these company's new products — developed using a total product modelling approach — move out into the marketplace, it marks the realization of a fundamental change in new product development thinking first mooted in 1991.
THE opening this month of the A.R.A. establishment at Bedford, which is described in this issue, is the culmination of the first step which the British aircraft industry has taken in the way of a pooling of resources for a co‐operative effort. Many people have been urging such co‐operation for a long time, but an industry which has grown up in an atmosphere of competition between individua...... hiện toàn bộ
