NEW AIRSCREW

MANY ADVANTAGES CLAIMED.

(Bj’ Telegraph—Press Association—Copyright) LONDON. May 13.

The ' “Daily Telegraph's” aviation correspondent says bench and flight tests have been made of a “contraprop” or co-axial oppositely-rotating airscrew with controllable pitch blades intended considerably to improve the efficiency of aircraft. The contraprop can be visualised as two airscrews close together mounted on two shafts, one running inside the other, turning in opposite directions. It possesses many advantages. The diameter of the airscrew is reduced, for which reason undercarriage design problems are reduced, especially with tricycle undercarriages. In addition the airscrews' pull is true, not inducing a plane to pull to right or left when taking off and it also gives planes greater manoeuvrability in the air.
