TAIL-LESS AEROPLANE.

CONSTRUCTION IN GERMANY

REDUCING ENGINE POWER.

TEST PROVES SUCCESSFUL.

• (Received September 20, 7-15 p.m.) Times Cable. LONDON, Sept. 19,

Tho Berlin correspondent of the Times says tho restriction imposed by tho Treaty of Versailles upon tho construction of military aircraft in Germany is profoundly influencing German research.

Aircraft makers abroad aim at obtaining the maximum of performanco through increased engine-power, , Germany aims at reducing engine-powor to a minimum and improving tho aerodynamic qualities of machines.

This accounts for the great interest taken in tho trial flights of a new Rhonrosittan tail-less aeroplane which has been pronounced satisfactory. Tho manufacturing company has been prominent in motor-less flying for a long timo. It first tried out man-driven modols. Now it has built a machine driven by a 10 horse-power " pusher" screw.

Tho surfaces of tho wing-tips give direction, elevation and lateral balance. The new machine climbed well and attained a speed of 50 miles an hour. It is an early example of the "flying wing" aeroplano toward which some firms are working, including Junkers, whoso new all-metal monoplane now being constructed will have engines and somo passenger accommodation in tho wings. By modifying aircraft design in this way German designers hopo to solve the economic problem of commercial aviation.
