Abstract

THE trials of R 100 and R 101, with the consequent revival of interest in airship technical matters, makes the present time not inappropriate for reviewing the alternative methods by which such craft can be propelled.

WHILE the general principles of gas‐fuel propulsion for airships have been enunciated in a former article, there remain to be considered both the gases available and the means whereby they can be procured.

Abstract

THE fifth of these annual conferences was held on 8 and 9 January at Southampton University. As usual the conference opened with a luncheon, at which the then Minister of Supply, the Rt. Hon. Reginald Maudling, was a speaker. The Minister pointed out that the aircraft industry was the object both of immoderate praise and intemperate criticism; in order to make a fair assessment of the industry's achievements it was necessary to compare them with those of other countries, which in practice meant the U.S.A. since no other country about which information was available had an industry of comparable size. Continental countries, although they had made outstanding technical advances, were able to export only a small fraction of the aircraft and equipment which the British industry has sent abroad in recent years.

Abstract

MAN'S increasing power over the physical world has been largely due to his ever‐growing knowledge of the chemistry and physics of materials. From the end of the Stone Age until almost the present, this developing mastery has largely depended on the metallurgist, who first by empiricism and then by the same means, leavened to an increasing extent by Science, has found means of producing, with but little regard to their specific gravity, substances possessing in greater or less degree those two outstanding qualities, hardness and ductility, on which progress, prior to the flying era, so much depended. In a world of over ninety elements, three quarters of which arc metallic, the combinations and permutations open to the experimentalist arc almost infinite. That these possibilities have not been neglected when the urge existed, is shown by a single example, aluminium. This metal, the discovery of which dates back little over one hundred years, now possesses over 600 alloys whose genesis dates from that of mechanical flight.

Abstract

THOUGH the airship is not infrequently described as a lighter‐than‐air craft, the usual meaning attached to the phrase obscures the fact that the vessel, having on occasions to fly cither in the heavy or the light condition, is nearly as dependent as the aeroplane on forces of dynamic origin.

Abstract

WHEN in 1925 the Airship Guarantee Company entered into possession of the remains of the old R.N.A.S. Airship Station of Howden, this once spacious and well‐equipped aerodrome was reduced, as a result of its post‐war vicissitudes, to a single airship shed standing in a sadly reduced area of marsh land, strewn with an infinite variety of debris, which the vendor's once enthusiastic clients had abandoned under the depressing influence of falling prices.

Abstract

NOW that helium is exclusively used in the airships of the United States, whilst its employment in the craft of other Powers has been visualised by Dr. Eckener, it is interesting to examine the history, properties, occurrence, origin, extraction and practical utility of this most remarkable gas, whose discovery is both a romance and a defence, should it be required, of scientific as opposed to industrial research.

Abstract

WHILE owing to helium's absence of chemical affinities it might at first sight be imagined that its separation from a mixture of other gases could best be carried out by effecting chemical changes in the latter, in only a very few cases is this a practical procedure. Indeed, at the present time all helium, which is being recovered from natural gas, is obtained by physical means.

Abstract

THE hull of R 100 is a sixteen‐sided polygon, measuring 709 ft. in length, with a maximum diameter, situated about two diameters, 266 ft., from the nose, of 133 ft., the height of the gas‐space within the framework being about 128 ft. at the maximum diameter. It is built up on a framework of 16 triangular longitudinals with 15 transverse frames, also triangular. No intermediate longitudinals or transverse rings are fitted. Along the centre runs an axial girder, taking the place of the wire rope used in Zeppelin construction, to which is brought the radial wiring forming the bulkhead between each of the gas‐bags. The gas capacity is 5,600,000 cub. ft., giving a gross lift of 160 tons. The transverse frames are not, as in R 101, of the “space frame” type, inherently stiff without bracing (in R 101 the triangular frames have a depth of 10 ft. 6 in.), but are only 2 ft. 6 in. deep, braced by the radial wiring. There are 15 gas‐bags, Nos. 14–15 being interconnected. In accordance with normal Zeppelin practice, automatic valves are fitted at the bottoms of the bags, discharging into fabric trunks leading to the upper surface. Hand‐operated valves are fitted at the top of 11 of the bags. Back as far as Frame 13 the axial girder is of triangular section, but from there aft it is square and forms an integral part of the cruciform fin structure. All girders, from which the longitudinals, transverse frames and axial girder are built up, are composed of Duralumin strip wound and riveted into tubes connected by stamped Duralumin bracing pieces.

Airspeed Limited of Christchurch Aerodrome, Hampshire, announces that Major Hereward de Havilland, D.S.O., hasjoined the Board of Directors of the Company and he and Mr J. Liddell arc appointed Joint Managing Directors. They will share the responsibility for the company's administration. Mr A. Townsley, as works director, will devote all his attention to increasing production activities, which include the contribution made to de Havilland manufacture as a whole. The positions of Mr A. E. Hagg, as technical director, Mr P. E. Gordon‐Marshall, as sales director, and Messrs F. T. Hearle and F. E. N. St Barbe, as de Havilland directors on the Airspeed board, remain unchanged.
