AERIAL RESEARCH.

GERMAN ACTIVITIES. J Treaty Restrictions Cause New Experiments. TAIL-LESS 'PLANE TRIED. I ' ("Times" Cables.) LONDON, September 20. The Berlin correspondent of the > "Times" says the restriction imposed by the Treaty of Versailles upon the construction of military aircraft in Germany is profoundly influencing German research. Aircraft makers abroad aim at obtaining the maximum of performancs through increased engine-power. Germany aims at reducing engine-power to a minimum and improving the aerodynamic qualities of machines. This accounts for the great interest taken in the trial flights of a new Rhonrosittan tail-less aeroplane which has been pronounced satisfactory. The manufacturing company has been prominent in motor-less flying for. a long time. It first tried out man-driven models. Now it has built a machine driven by a ten horse-power "pusher" screw. The surfaces of the 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" aeroplane toward which some firms arc working, including Junkers, whose new all-metal monoplane now being constructed will have engines and some passenger accommodation in the wings. By modifying aircraft design in this way German designers hope to solve the economic problem of commercial aviation.
