1922
1922 - 0733.PDF
DECEMBER 14, 1922 Since the war Handley Page, Ltd., have produced a number of commercial types, all being clearly developments of the original 0-400. First of all the firm produced the W.8, with two Napier " Lion " engines, which won the Air Ministry competition (large class) at Martlesham Heath. This machine was for some time put on the London-Paris route, where it made some trips in record time. A later development was the W.8.B, which was fitted with Rolls-Royce " Eagle " engines and carried 12 passengers. For next year's services a further development, the W.8.C will be put on, this machine to have seating accommodation for 16 passengers. Lately Handley Page, Ltd., have turned their attention to the design and construction of torpedo planes, of which mention may be made of the " Hanley," in which, for the first time, use has been made of the slotted wing invented by Mr. Handley Page. A D.H.o was first fitted with slotted ^m wings in order to test the idea, and the results were so promising that a cantilever monoplane wing with slots was fitted to a D.H.o fuselage in order to test the effect of slots on a high-lift wing (the section being airscrew 4). It was found that again the full-size results bore out the model experiments, and consequently the " Hanley " torpedo plane was built to incorporate the slots in a machine designed for a specific military purpose. The first of the " Hanley " machines had rather ugly wing tips and a complicated undercarriage. In spite of these drawbacks the machine had a good performance, and in the latest type of " Hanley " a simpler undercarriage and finer wing tips have resulted in an increase in speed of 10 m.p.h. Concerning the activities of the operational side of the firm, known as Handley Page Transport, Ltd., something will be found elsewhere in this issue. THE HAWKER ENGINEERING CO., LTD. T. O. M. Sopwith, Director. Upon the Sopwith Aviation Co. going into liquidation in 1920, the H. G. Hawker Engineering Co., Ltd., was formed by the late Mr. H. G. Hawker, Mr. F. Sigrist and Mr. T. O. M. Sopwith. The late Mr. Hawker was, as is well known, test pilot to the Sopwith Aviation Co., and Mr. Sigrist was, from the founding of that firm up to 1919, works manager, while Mr. Sopwith will need no introduction, his name being famous all over the world as one of the first British pilots and founder of the Sopwith Aviation Co., whose products during the war were among the first in the world. In the Hawker Engineering Co. Mr. F. Sigrist is managing director, other directors being Mr. T. O. M. Sopwith, Maj. V. W. Eyre, Mr. F. L. Bennett, who is acting as works manager, and Capt. L. F. Peaty, brother-in-law of the late Mr. Hawker. The chief designer of the firm is Capt. B. Thomson. The H. G. Hawker Engineering Co. started at the old works of the Sopwith Aviation Co. at Kingston-on-Thames, and have now taken over the whole of the main premises. At present they are engaged upon re-conditioning a large number of D.H.gA's and Sopwith " Snipes." Two new designs by Capt. Thomson have been submitted to and accepted by the Air Ministry, and are at present under construction. Little may be said about them, except that one is a reconnaissance two-seater cantilever monoplane, and the other a single-seater fighting scout. GEORGE PARNALL AND CO., BRISTOL The Parnalir.Panther " is a ship's 'plane with folding fuselage [instead.of the more usual folding wings. 733 D 2
