Until recently Hamilton has had a virtual monopoly of the propeller business. Lately, however, it and its most formidable rival, famed old Curtiss-Wright Corp., have been seeking another propeller improvement-full feathering of the blades. Curtiss-Wright devised an electric motor which nestles in the hub of the propeller and changes the pitch to any angle from o° to 90° whenever the pilot wishes. If an engine fails, the pilot merely adjusts the propeller pitch to 90°, which means that the blades feather (present a streamlined knife-edge to the wind), do not revolve. This...
...cooling air is not so effective as it is later when the plane is flying faster but when the engine needs less cooling because it is throttled down. To meet these shifting conditions the NACA has devised a shifting cowling with two nose slots. Air enters around the propeller hub, flows back over the cylinders, then is turned forward and issues from a small slot running the entire circuit of the cowling front. A gearshift makes this slot movable, so that air pressure on the engine can be controlled and adjusted to any cooling requirement...
