JANUARY 14, 1926 THE NEW BRISTOL "CHERUB Series III Light 'Plane Engine Passes 100 Hours Type Tests As a result of the outstanding successes of the original Bristol " Cherub " engines in the 1924 and 1925 Lympne Light 'Plane meetings, and other competitions in Germany and the United Stales of America, the Bristol Aeroplane Company decided to develop this engine further, with the idea of putting it on a basis fully equal to the best modern large aero engines as regards reliability and performance. Although there were those who doubted the possibility of obtaining real reliability in a small very high speed light 'plane engine, the Bristol Company has managed, by taking advantage of their valuable experience gained in competition work, by careful re-designing, and as a result of nine months of development work, to produce a small light engine, which compares well with aero engines of more than ten times the power. Thus the " Cherub" series III develops a normal power of 33 b.h.p. at 2,900 r.p.m., and a maximum of 36 b.h.p. at 3,200 r.p.m. The weight of the engine is only 951b., or 2*88 lb. perh.p. on normal power. At the same time the fuel and oil consumptions are low, the former averaging 2 galls, per hour and the latter 1 pint per hour, both at normal speed and power. That the relia- bility claimed for it has been attained in the " Cherub " III is proved by the fact that one of these engines has passed THE LATEST " CHERUB " : These three views illustrate the Series III engine, which has recently passed the Air Ministry's 100 hours' type test. 19
