Description
Technical field
The utility model relates to a kind of manpower hydrofoils.
Background technique
Currently, most of waterborne vessel is provided by huge hull enough floating by Archimedes principle
Power, and manpower ship is mostly used arm paddle offer power and also still to overcome very big resistance even water cycle.
Hydrofoil is compact, lighter in weight, runs also do not need to overcome very big resistance in water.Hydrofoil is to utilize
Bernoulli principle enters water section to hull and has done hydrofoil.Hydrofoil is strip, and it is horizontal that section is that be above below arch be,
Known by bernoulli principle, when such structure moves in a fluid, upper and lower surface will receive different pressure, following table surface pressure
Greater than upper surface pressure, and this pressure difference size be mainly it is related with the structure of the hydrofoil itself, also with the relative velocity of fluid
Related, speed is bigger, and top and bottom differing pressure is bigger.In addition, this pressure difference size is also directly proportional to the lower surface area of hydrofoil,
Such as aircraft can reach certain speed by wing, can fly；Meanwhile this pressure difference size and fluid density are also related
System, the density of water are far longer than the density of air, put down so the speed that hydrofoil is far smaller than aircraft can be thus achieved with gravity
