1923 - 0005.PDF
JANUARY 4, 1923 the sea should be very remote. Incidentally, it is not without interest to mention that, in addition to the six Caudron C.61 machines ordered by Lateco£re, two more were purchased on December 19 by another firm. We wonder if any other firm can show similar results. DE MONGE^BUSCAYLET, ISSY-LES-MOULINEAUX THE machine exhibited by M. Louis de Monge suffers from being placed in a very unfavourable position underneath the gallery, forming in this respect the " opposite number " of the Handley Page. And about both machines it may be said that they were deserving of a more prominent position. It would appear that both were late in applying for space, and that consequently all the large stands had been allocated. The de Monge machine, designed by M. L. de Monge, and constructed by Buscaylet et Cie., is a parasol monoplane chaser, known as the type "52 C-i." It is built almost it appears that a veryjgreat number of set-screws would need to be undone before one could get at the engine. A feature of the engine housing is that it is entirely closed in front, the propeller shaft projecting through a small opening. On the front of the airscrew, which, incidentally, is one of the all-metal adjustable pitch Lumi£re-Leitner-Watts pro- pellers, built in France under licence, is a small spinner carrying the lines of the fuselage into a neat streamline head. The covering of the fuselage, up to the point aft of the pilot's seat, where the monocoque construction begins, is covered with sheet Duralumin. The undercarriage struts are in the form of box members built-up from Duralumin sheet. Their shape is indicated in some of our sketches. At the top, the " legs " of the undercarriage are joined to the main fuselage bulkheads by transverse hinges, while at the lower end they carry the rubber shock-absorbers and axle. An anti-bouncing device, THE DE MONGE-BUSCAYLET MONOPLANE : This machine is built entirely of metal, mostly Duralumin, with the exception of the rear portion of the fuselage, which is a wood monocoque. entirely of metal, chiefly -.Duralumin, the only exception being the rear portion of the fuselage, which is of monocoque wood construction. The front portion of the fuselage is built-up of box formers or bulkheads of sheet Duralumin, reinforced by internal diagonal members. Carried on cantilever bearers, also of Duralumin, projecting forward from the front bulkhead is the 300 h.p. Hispano-Suiza engine, which is entirely cowled-in, so much so that it was suggested that the only way to get at the engine for any adjustments would be by means of a tin opener. The cowling certainly makes for clean lines, but in the form of a friction damper, is incorporated, and is indicated in a sketch. It will be noticed that the axle is " floating " in its slot, the shock-absorbers sloping upwards and outwards from their attachment. The centre-section of the wing is carried on struts of a construction similar to that of the undercarriage, at any rate, as regards the front spar. The rear spar is supported on Duralumin circular section tubes, and the structure is braced fore and aft by diagonal tubes, forming a letter N in side view. As exhibited, the box struts were uncovered, but it is, we believe, intended to cover the box strut and sloping j -de Monje T/peSS-e-l. THE DE MONGE-BUSCAYLET, TYPE "52 C-l ": The upper sketch shows the undercarriage, while on theleft and right are shown upper and lower ends of the undercarriage box struts. Note the friction device which acts as a damper gear. The small inset shows the front elevation of the machine, with thin centre-section. Thewings have a very pronounced sweep back. .. -
