SECRETS OF FLIGHT

A SENSATIONAL DEVICE

(By Air Mail—From Our Own Correspondent)

LONDON, 20th February

Sensational claims are made for the latest novelty in aviation equipment, This device is a twin air-screw with what is technically described as a differential self-balancing transmission. It is said to add up to 50 per cent to engine power and speed of plane. So far it has been tested, only theoretically, by ground experiments with airscrew models, but there will be further practical tests in the air when a machine has been built with the new equipment of propeller lilades. Tlie inventor, whose name is being kept secret, is understood to be a Russian emigre, who has done other work' for the British Government, including important machine-gun gadgets. It is early to speak with confidence of the new idea, but experts have long believed that only by slow degrees, as in the case of other forms of mechanical transport, shall we wrest the bird’s secret Of flight from Nature. Possibly this may be an important advance in that direction. If existing air speeds can bo doubled, amazing potentialities open up at once.
