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.
(1) Theoretical consideration of aerofoils of limited span led, in Article III, to a need for some assumption as to lift‐grading along the span, to give the span‐grading of circulation. Fig. 1 shows at (a) the experimental distribution of lift along a rectangular aerofoil of 7·6 per cent camber and aspect ratio 6, at an angle of incidence of 6 deg. At (b) elliptic loading is shown, which, ...... hiện toàn bộ
PurposeNowadays, many micro‐satellites rely on three‐axis stabilization using at least three reaction wheels (RWs) for attitude control. Typically, RWs are mounted separately within the satellite and leads to long wires from each RW to the associated electronics. Placement and other constraints may also arise during integra...... hiện toàn bộ
