NEW AIR PROPELLER
Shown for the first time at the Western Aircraft Exposition at Los Angeles, this reversible propeller, tried out secretly by a naval airplane, opens a whole bag of new aerial tricks. It will serve as a “brake” in the air; it permits a plane to taxi in reverse; and, by increasing and decreasing the pitch while in flight, it permits a motor to function at fullest efficiency at any speed and at any altitude—the latter by “grabbing” more thin air as the plane goes to extreme heights. Aerial combat tactics are influenced by the new “prop” and other minor features are present, such as the no-dust, no-wind conditions as passengers enter or leave the cabin. One of the owners, A. K. McLeod of Los Angeles, is pointing out its mechanical features to a pair of fair flyers.
