PURPOSE: A hull propeller provides a powerful driving force by applying the hull propeller to a large vessel and to reduce fuel by remarkably increasing the speed of the propeller. CONSTITUTION: A hull propeller comprises a propulsion rod support(10), a propulsion rod(11), a compressed air controller(14), and a propulsion plate(12). The propulsion rod is accepted in the propulsion rod support and performs a forwards and backwards motion. The compressed air controller sprays compressed air to the inside of the propulsion rod support. The propulsion plate is coupled to the rear of the propulsion rod and generates driving force by discharging water from a water inlet(13) to a water outlet(24). |
