The physics of the operation of the pop pop boat is similar to that of the Feynman sprinkler, a submerged sprinkler which is seen to turn weakly or not at all as water is sucked in through it. In both cases, the reaction force on the solid device caused by the sucking in of the fluid is balanced by the fluid impinging on the inside of the device.
Proteus is an experimental watercraft developed by Marine Advanced Robotics, Inc. (formerly Marine Advanced Research). It is the first vessel of the wave adaptive modular vessel-type (WAM-V).
Wave-making resistance is a form of drag that affects surface watercraft, such as boats and ships, and reflects the energy required to push the water out of the way of the hull. The hull of a moving watercraft creates waves (a wake ) which carry energy away and resist the motion of the watercraft.
MS Tûranor PlanetSolar, known under the project name PlanetSolar, founded by the Swiss explorer Raphaël Domjan, is the largest solar-powered boat in the world [2] and launched on 31 March 2010. The vessel was designed and engineered by LOMOcean Marine. In May 2012, the vessel became the first solar electric vehicle ever to circumnavigate the ...
This boat was designed by Comte de Lambert. [8] This had 5 variable pitch fins on the hull beneath the water so inclined that when the boat begins to move "the boat rises and the planes come to the surface" with the result that "it skims over the surface with little but the propellers beneath the surface".
While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric motor or internal combustion engine driving a propeller, or less frequently, in pump-jets, an impeller. Marine engineering is the discipline concerned with the engineering design process of marine ...
The turning rotation of a vessel about its vertical/Z axis. An offset or deviation from normal on this axis is referred to as deviation or set. This is referred to as the heading of the boat relative to a magnetic compass (or true heading if referenced to the true north pole); it also affects the bearing.
Rotor ship E-Ship 1. A rotor ship is a type of ship designed to use the Magnus effect for propulsion.The ship is propelled, at least in part, by large powered vertical rotors, sometimes known as rotor sails.
