shovel for rowing canoeing competition for recreational use with longherone superior edge terminal slot directional

摘要

the present invention relates to a shovel from rowing to revolutionary design concept, developed to optimize the system of energy transmission in the dynamic of the vessels.the design of the invention uses constructive technology production of composite materials that constitute the invention in a single part.design specifications for a shovel very static in water in order to make more energy - speed the craft than the "classical" symmetrical or shovelsasymmetric. this is achieved with a shovel having width limited waves to minimize the time of immersion of the shovel in the water, corresponding to the time of the minimum speed of the vessel.they are: (1) higher longherone: directional compensator, compressor, joint expander, a constituent structure. 2) board terminal: compressor, valves, a constituent structure.3) slot: directional compensator pressure.the invention is operationally than the "conventional" shovelshaving reduced the translation of the shovel in the water for loss of load on the blade edges and being perfectly stable and read.
