Abstract

NEARLY twenty years have passed since the author had the pleasure of giving a paper on the same subject to this Society. Progress in the meantime as regards the means and art of flying has been not only sustained, but rapid, as is brought out by the simple facts contained in Table I. The amazing technology is well represented by the De Havilland Comet, which develops 460 h.p. with a weight ratio of 12 lb. per h.p. It therefore becomes interesting and perhaps useful to determine the extent to which metallurgy has contributed and is contributing.

Abstract

In addition to the metallurgists and engineers, who have to deal with it professionally, almost everyone is familiar with rust, and its appearance no doubt evokes varied responses from different members of the community. The response of some of the makers and users of iron and steel 30 years ago was to find ways of preventing corrosion, which even then was costing vast sums of money in maintenance and replacement of structures. It was with this object in view that the Iron and Steel Institute, together with the National Federation of Iron and Steel Manufacturers, set up a Corrosion Committee in 1928, under the chairmanship of the late Dr. W. H. Hatfield, F.R.S., to study ways of reducing the corrosion of iron and steel to a minimum, either by improving the resistance of the materials themselves or by adopting methods of protection. The Committee decided on a broad scheme of investigation, which included the conduct of both fundamental and applied research. The fundamental researches continued at Cambridge for a period of more than 25 years until the recent retirement of Dr. U. R. Evans, F.R.S., and have resulted in important contributions to our knowledge of corrosion processes.

Abstract

THE oxidation behaviour of low binary iron alloys with aluminium, chromium and silicon in air has been discussed at length. Rather less work has been performed on the ternary systems, Fe‐Cr‐Al and Fe‐Cr‐Si, and very little on Fe‐Al‐Si alloys.

Abstract

THE variation in weight gains of the binary (and ternary) iron alloys with change in the atmosphere composition clearly demonstrates the sensitivity of oxidation behaviour to conditions. In particular it can be seen from Figs. 3 and 4 that the presence of atmospheric pollutants (sulphur and nitrogen oxides, water vapour) markedly increases the oxidation rate in air. This is supported by the further marked increase in oxidation in flue gases produced by the presence of sulphur oxides. Oxidation in flue gases at 700°C is far greater than in air, Figs. 7 and 10 and Table 3. This is due to the formation of wustite which was not present in air‐formed oxide scales.

Abstract

UP to midday on Monday, October 22, the “record” for a flight from England to Australia stood at 6 days 17 hours 45 minutes. Scott and Black, by landing at Port Darwin at 11.8 in their D.H. Comet that morning, lowered this to 2 clays 4 hours 24 minutes—an amazing performance. They finally won the race by crossing the finishing line at Melbourne 2 days 22 hours 50 minutes after their take‐off from Mildenhall. They were followed in order by Parmentier and Moll in the K.L.M.American‐built Douglas, Roscoe Turner and Pangborn in a Boeing 247 Commercial aeroplane, and Jones and Waller in a second Comet—to mention only the first four to arrive. Actually, the previous “record” time for a flight between England and the nearest point in Australia has been beaten by no less than six competitors in the race.

Abstract

ON another page of this issue will be found a description of a novel arrangement of the tail surfaces of an aeroplane which we have christened the “Vee Tail.” Known in Poland, the country of its origin, as an “oblique empennage,” it is, in fact, in the form shown, simply a pair of horizontal surfaces, fixed and moving, set at a positive dihedral angle of about 30 deg. to each other. In itself there would be nothing particularly remarkable in this, but the significant point of the arrangement is that it dispenses with the fin and rudder, there being no vertical surfaces at all.

Abstract

IT rather looks as if the aeroplane was on the point of becoming interesting again. This perhaps appears a somewhat startling statement, and it may be controvertible from two aspects. In the first place, the real enthusiast will no doubt say that the aeroplane is always interesting; whereas others will sec no reason why we should suddenly visualise advances.

Abstract

WE cannot help envying those who have achieved fixed and definite views on the question of education and training. There is no subject on which opinions differ more widely. It is as many sided as a dice—and there are moments of pessimism when we feel that the results depend almost equally on chance. The real truth is, we suppose, that mental outlooks and temperaments differ to such an extent that what is the perfect curriculum for one student is totally unsuitable for another. In a perfect World, where time and expense were limitless, each candidate would follow his own course with tutors specially selected to care for his own particular needs. But unfortunately this is not possible and it is necessary for each student to be treated as one of a mass and pressed into the chosen mould. If he is so unfortunate as to be incompressible into that particular shape, then so much the worse for him and he cannot avoid the fate of being thrown out as a reject.

Abstract

IN modern times, increasing emphasis is being laid on specialization and there is so much research being made into the many intricate details of the most abstruse problems that members of one group of engineers are too often unaware that their own problems, or others closely related to them, have already been investigated.
