ROTOR ’PLANES
SUCCESSFUL EXPERIMENTS. SHIP TRIALS IN BALTIC. (Sun Special.) LONDON, January 12. The National Physical Laboratory is carrying out special tests for applying Flettner’s rotor principle to aviation. It has been proved that the lift per horse power, with the rotary cylinders exceeds anything hitherto obtained from wings. The laboratory is now experimenting with a view to combining wings and the cylinders. A message from Berlin says that Flettner’s rotor ship averaged nine knots in heavy winds in the Baltic. Herr Anton fHettner is the inventor of a strange ship in which masts and sails are replaced by enormous ribbed cylindrical funnels. It is claimed that the action of the wind on the funnels, which are made to rototate at a great speed, provides power to drive the ship greater than would be obtained by exposing to the wind a sail area ten times greater than that of the cylinders.
