Propeller design and manufacturing, design and production of experimental airplanes Ole (Olaf) [ 1 ] Fahlin (May 8, 1901 – January 26, 1992) [ 2 ] [ 3 ] was a Swedish aviator who made his career manufacturing propellers and aviation products in the United States.
Ericsson later presented drawings of USS Monitor, a novel design of armored ship which included a rotating turret housing a pair of large cannons. Despite controversy over the unique design, based on Swedish lumber rafts, [26] the keel was eventually laid down in a New York shipyard and the experimental ironclad was launched on March 6, 1862 ...
John Ericsson, designer and builder of the Monitor, had been born in Sweden, although he had become an American citizen in 1848, and offered to share his design with the Swedes. In response they sent Lieutenant John Christian d'Ailly to the United States to study monitor design and construction under Ericsson.

A cleaver is a type of propeller design especially used for boat racing. Its leading edge is formed round, while the trailing edge is cut straight. It provides little bow lift, so that it can be used on boats that do not need much bow lift, for instance hydroplanes, that naturally have enough hydrodynamic bow lift.
