MILITARY AEROPLANES

PROGRESS IN GREAT BRITAIN NEW HEAVY-OIL ENGINES (British Official Wireless.) (United Press Association.) (By Electric Telegraph—Copyright.) RUGBY, June 18. (Received June 17, at 5.5 p.m.) Among the machines in the Royal Air Force display at Hendon this month will be two standard types of military aircraft fitted with engines consuming heavy oil, which is less inflammable, cheaper, and less bulky than .petrol. Its advocates believe that the introduction of Diesel engines will make a revolution in aviation. One of the machines is fitted with Rolls Royce water-cooled engines, and is the first Diesel aero engine to pass the Air Ministry type test, involving 50 hours of full throttle running. The other has an air-cooled British Phoenix engine, the most powerful of its kind in the world. Although weighing only 9801bs complete, it produces 380 horse-power. The Wapiti machine in which this engine is fitted has climbed to over 10,000 feet, and the engine has been run for over 180 hours.

Another prominent exhibit in the display, which, as usual, will afford a striking demonstration of the progress of aviation research, is a short six-engined flying boat weighing 33 tons, the largest military aircraft in the world. The worid's fastest military aircraft will bo seen in modified Hawker-Fairy aeroplanes capable of over 260 miles an hour.
