SUBMERSIBLE BOAT AND METHOD OF SUBMERGENCE RACE

摘要

PURPOSE:To enable an underwater movement, by providing submerging blades on both the sides of a motorboat fitted with a waterproof cover, and by coupling the blades to a crankshaft inside the motorboat, and using feet to operate the crankshaft. CONSTITUTION:Submerging blades 2 of appropriate size are provided on both the sides of a submersible motorboat B fitted with a waterproof cover 1. The blades 2 are coupled to a crankshaft provided in the motorboat. A simple method of swinging the crankshaft forward by toes is adopted to incline the leading edges of the submerging blades 2 down into water to enable the motorboat to sink due to the resistance of the water.
