JANUARY 27, 1927 THE BEARDMORE "TYPHOON" MARK I ENGINE Flying in the Avro " Aldershot" IF one were to attempt to sum up the outstanding features ofthe new Beardmore " Typhoon " engine in as few words as possible, it could be done as follows :—" Six Cylinders, 800h.p., 1,350 r.p.m." Yet that would not entirely cover the case, and one should add that the engine is of the invertedtype, facilitating the aircraft designer's work of giving his machine a " clean nose " and the pilot a good view. Under results, not the least important of which is the manner inwhich the engine may be accommodated in the nose of an aeroplane. It is a somewhat curious fact that although the" inverted " type of engine was in use in aircraft long before the war 1914-18 (for instance, there was an inverted Germanaero engine, we forget at the moment whether it was a Mercedes or a Benz), the type has received relatively little attention in The Avro "Aider- shot " with 800 h.p. Beardmore " Typhoon " en- gine. Three- quarter front view. [" FLIGHT " Photograph these four heads, however, is really included all that is essentialin the somewhat radical departure from standard practice which the " Typhoon " represents. It may be recollectedthat in our issue of November 4, 1926, a brief illustrated description of the Beardmore " Cyclone " engine was given.That engine is to all intents and purposes similar to the " Typhoon," except that it is " right way up." The fact of" inverting " the " Typhoon," however, has several important modern times. The Americans have done almost everythingthat it is possible to do with the " Liberty " engine, even to turning it into an air-cooled, and they have also got it to runupside-down in a flying boat. In this country there have been rumours of an engine of the feline tribe being inverted,but Air Ministry7 shyness has prevented any reference to it. Generally speaking, however, very little has been done withthe inverted type of engine for aircraft, and yet when one The Beardmore " Typhoon "is a six-cylinder " in- verted " engine. Our photograph shows it mounted in the Avro "Aldershot ". The radiator is placed aft of and below the engine. [" FLIGHT " Photograph • • • * • 44
