WONDERS FOR HENDON.

RUGBY, June 18

Among the machines which are to take part in the Royal Air Force display at Hendon on June 24 will be two standard types of military aircraft fitted with engines that consume heavy oil, which is less inflammable, cheaper and less bulky than petrol.

The advocates of heavy oil believe its use with 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's type test, which involves 50 hours of full throttle running.

The other machine has an air-cooled British Phoenix engine, the most powerful of the kind in the world. Although it weighs only 9801b complete, it produces 380 horse-power. The "Wapiti machine in which this engine is fitted has climbed to an altitude of more than 10,000 ft and the engine has been run for more than 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 sixengined flying boat which weighs 33 tons. This is the largest military aircraft in the world.

The world's fastest military aircraft will be seen in the modified HawkerFairey aeroplanes. These are capable of attaining a speed of more than 2GO miles an hour.
