Propellers are used to pump fluid through a … See more Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the … See more Shaft protection For smaller engines, such as outboards, where the propeller is exposed to the risk of collision with … See more 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, … See more • Titanic's Propellers • Theory calculation propellers and wings: detailed article with blade element theory software application • "What You Should Know About Propellers For Our Fighting Planes", November 1943, Popular Science See more In the nineteenth century, several theories concerning propellers were proposed.
