Among the machines in the Royal Air Force display at Hendon will be two standard types of military aircraft fitted with engines consuming heavy r'il which is less inflammable, cheaper and less bulky than petrol. Its advocates believe the introduction of the Diesel engine will make a revolution in aviation. One of the machines is fitted with Rolls Boyce water-cooled engines and is the first Diesel aero engine to pass the Air Ministry type test, involving 5-0 hours’ full-throttle running. The other machine has an air-cooled British Phoenix engine, the most powerful of the kind in the world although weighing only 980 pounds complete. It produces . 3SO horse-power. The Wapiti machine in which this engine is fitted has climbed to over 16,000 feet and the engine lias 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 sixengined flying boat weighing 33 tons. Tt is the largest military aircraft in the world. The world’s fastest military aircraft will be seen in a modified Hawker Fairy aeroplane capable of over 260 miles an hour.
