JANUARY 29, 1920 " Flight " Copyright THE 160 h.p. BEARDMORE ENGINE : Induction and Exhaust sides them in detail. The new water-cooled engine is, however, a novelty, and possesses several new and inreresting features. As will be seen from the accompanying photograph, the 600 h.p. Anzani water-cooled engine is of the radial type, but differs from usual design, in that the 20 cylinders are arranged in 10 pairs. Each pair has an overhead camshaft, driven by bevel gearing. In external appearance this engine is of extremely clean design. It will be noticed that the distributors are mounted on the front cover of the crank case. Unfortunately particulars as to weight, fuel consumption, etc., of this engine were not available, but later we hope to be able to publish a more detailed description. Beardmore Aero Engine, Ltd. This famous British Aero engine firm had been somewhat unfortunate in the allocation of stands, being hidden away in the upper gallery, where, it is to be feared, it did not attract the attention it deserves. In fact, the representatives of several journals have failed to make any reference to it, although professing to mention all the British engine firms which exhibited at the Paris Show. The fact that Messrs. Bcardmore were not included in the official catalogue may also have been, to some extent, responsible for this omission. The Beardmore exhibits included only those engines which have been in use during the War, and the design of which is already so familiar to readers of FLIGHT as to require no detailed reference here. The 120 h.p. engine was an old and tried friend already before the War, and the 160 has done extremely useful work udering thWar, mainly as installed in the Arm- strong-Whitworth machines, but also in other types, an<although ultimately superseded by more powerful engine the Beardmores were used on night-bombing work up to tlend of hostilities. As regards the commercial possibilities of the Beardmoi aero engine, it may be remembered that some months ago v, published in FLIGHT an account of the purchase by Messr; Beardmore of all the Beardmore engines in existence from th Government, and it was then stated that each engine would r. tested and sent out with its complete test history sheet an a graphic record of the endurance run. As the number c engines purchased back ran into thousands, it will be unde stood that Beardmores are in a position to furnish spare pan at a moment's notice, which, coupled with the fact ths immediate delivery can be guaranteed, should go a longjwa towards popularising the Beardmore engine for use on civilia aeroplanes and seaplanes. For certain classes of work tfc high power of the more modern aero engines will not t required, and it is for this class of work that the Beardmoi engine will be found useful. It is true that the weight pt horse-power is somewhat greater than that of the most moder designs, but, on the other hand, the Beardmore is designe to run comparatively slowly, which means less wear and tea on bearings and reciprocating parts, and the feasibility < using direct drive, thus avoiding the use of reduction gearin; For that matter the weight is not prohibitive, being less tha 8 lbs. per h.p., complete with radiator, water, fuel, oil, an tanks for a six hours' flight. " FSgkt" Copyright THE BREGUET-BUGATTI POWER UNIT : This unit, which is rated at 800 h.p., consists of two Brfeguet- Bugatti engines placed end to end, and one slightly higher than the other, and driving a main airscrew shaft. Automatic clutches throw either engine out of gear in case of a breakdown _ 122
