Abstract
A device for starting an aircraft engine which is capable of being started by rotating a propeller connected to the crankshaft of the engine. The device comprises an anchor for fixedly positioning on the landing surface below the propeller; this anchor can be held in place by a portion of the aircraft itself; in one case, the nose wheel and in another case, a separate extension arrangement. A holding device is provided for holding the propeller and crankshaft of the engine against rotation in a proper starting position while a rotative device is provided for placing a biasing force on the propeller for rotating it. When desired, the holding device is remotely released and the propeller is pulled through the compression stroke by the rotative device and rotated in a manner to start the engine by the rotation of the crankshaft. Each of the holding device and rotative device has a propeller tip cap for connection to the propeller, while the other ends are fixed to the anchor.
