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 device for fixedly positioning on the landing surface below the propeller; this anchor device 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 connection to the anchor device for holding the propeller and the crankshaft of the engine against rotation in a proper starting position while a rotative device is provided for connection to the anchor device for placing a biasing force on the propeller for rotating it. The anchor device has forwardly extending arms, or members, with an attaching device fixed below the propeller, the holding device and rotative device are each fixed between the propeller and the attaching device. The arms, or members, can be made adjustable to adapt to different width tires and can be foldable lengthwise and in a sidewise overlapping manner to be compact for storing.
