Hydroplane (boat)
A hydroplane (or hydro, or ''thunderboat'') is a fast motorboat, where the hull shape is such that at speed, the weight of the boat is supported by planing forces, rather than simple buoyancy. A key aspect of hydroplanes is that they use the water they are on for lift rather than buoyancy, as well as for propulsion and steering: when travelling at high speed water is forced downwards by the bottom of the boat's hull. The water therefore exerts an equal and opposite force upwards, lifting the vast majority of the hull out of the water. This process, happening at the surface of the water, is known as ' foiling'. Hydroplane design Early designs of the 1920s were often built by amateurs, who employed the lightest materials available to them at the time, which were often glued timber boarding or plywood on the floor, plywood topsides, and varnished canvas decks. Most were about long and stepped hulls were employed with a step to induce air under the hull, to enable the boat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroplane Racing
Hydroplane racing (also known as hydro racing) is a sport involving racing hydroplanes on lakes and rivers. It is a popular spectator sport in several countries. Racing circuits International professional outboard hydroplane racing The Union Internationale Motonautique (or "UIM", headquartered in Europe) sanctions many different hydroplane categories of hydroplane powerboat racing. International UIM F-125, F-250, F-350 and F-500 Circuit powerboat races are very popular in Europe, Asia, and the United States. UIM's O-series hydroplane Formula Circuit racing events are some of the most prestigious Professional Racing Outboard (PRO) hydroplane events in the world. National powerboat racing teams compete for national and international titles in these hydroplane racing circuits. The American Power Boat Association (APBA) sanction similar PRO class national title events in the United States. Professional F-series World Cup Title powerboat races are held at Europe, United States, and w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aquaplaning
Aquaplaning or hydroplaning by the tires of a road vehicle, aircraft or other wheeled vehicle occurs when a layer of water builds between the wheels of the vehicle and the road surface, leading to a loss of traction that prevents the vehicle from responding to control inputs. If it occurs to all wheels simultaneously, the vehicle becomes, in effect, an uncontrolled sled. Aquaplaning is a different phenomenon from when water on the surface of the roadway merely acts as a lubricant. Traction is diminished on wet pavement even when aquaplaning is not occurring. Causes Every vehicle function that changes direction or speed relies on friction between the tires and the road surface. The grooves of a rubber tire are designed to disperse water from beneath the tire, providing high friction even in wet conditions. Aquaplaning occurs when a tire encounters more water than it can dissipate. Water pressure in front of the wheel forces a wedge of water under the leading edge of the tire, cau ...

Floatplane
A floatplane is a type of seaplane with one or more slender floats mounted under the fuselage to provide buoyancy. By contrast, a flying boat uses its fuselage for buoyancy. Either type of seaplane may also have landing gear suitable for land, making the vehicle an amphibious aircraft. British usage is to call "floatplanes" "seaplanes" rather than use the term "seaplane" to refer to both floatplanes and flying boats. Use Since World War II and the advent of helicopters, advanced aircraft carriers and land-based aircraft, military seaplanes have stopped being used. This, coupled with the increased availability of civilian airstrips, have greatly reduced the number of flying boats being built. However, numerous modern civilian aircraft have floatplane variants, most of these are offered as third-party modifications under a supplemental type certificate (STC), although there are several aircraft manufacturers that build floatplanes from scratch. These floatplanes have found thei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flying Boat
A flying boat is a type of fixed-winged seaplane with a hull, allowing it to land on water. It differs from a floatplane in that a flying boat's fuselage is purpose-designed for floatation and contains a hull, while floatplanes rely on fuselage-mounted floats for buoyancy. Though the fuselage provides buoyancy, flying boats may also utilize under-wing floats or wing-like projections (called sponsons) extending from the fuselage for additional stability. Flying boats often lack landing gear which would allow them to land on the ground, though many modern designs are convertible amphibious aircraft which may switch between landing gear and flotation mode for water or ground takeoff and landing. Ascending into common use during the First World War, flying boats rapidly grew in both scale and capability during the interwar period, during which time numerous operators found commercial success with the type. Flying boats were some of the largest aircraft of the first half of the 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gallaudet Hydroplane
The Gallaudet Hydroplane ( Gallaudet Wing-Warping Kite or Hydro-Bike) is an early aircraft employing the use of wing-warping for roll control. Development The Gallaudet Hydroplane was built in Norwich, Connecticut by Edson Fessenden Gallaudet Edson Fessenden Gallaudet (April 21, 1871 in Washington, D.C. – July 1, 1945 in Pine Orchard, Connecticut) was a pioneer in the field of aviation. He was best known for his development of practical airfoils and aircraft propulsion syst .... The principle of wing-warping was independently applied to this kite/aircraft/glider several years before the Wright Brothers applied it to their Wright Flyer. (along with Jean-Marie LeBris, John J. Montgomery, Clement Ader, D.D. Wells, and Hugo Mattullath). The Wrights later applied for a patent on wing-warping, which led to the widespread use of the aileron control method to avoid the Wright's airplane patents. Gallaudet generically employed the name hydroplane to many of his future seapl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrofoil
A hydrofoil is a lifting surface, or foil, that operates in water. They are similar in appearance and purpose to aerofoils used by aeroplanes. Boats that use hydrofoil technology are also simply termed hydrofoils. As a hydrofoil craft gains speed, the hydrofoils lift the boat's hull out of the water, decreasing drag and allowing greater speeds. Description The hydrofoil usually consists of a winglike structure mounted on struts below the hull, or across the keels of a catamaran in a variety of boats (see illustration). As a hydrofoil-equipped watercraft increases in speed, the hydrofoil elements below the hull(s) develop enough lift to raise the hull out of the water, which greatly reduces hull drag. This provides a corresponding increase in speed and fuel efficiency. Wider adoption of hydrofoils is prevented by the increased complexity of building and maintaining them. Hydrofoils are generally prohibitively more expensive than conventional watercraft above a certain disp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Planing (boat)
Planing ( ) is the mode of operation for a waterborne craft in which its weight is predominantly supported by hydrodynamic lift, rather than hydrostatic lift (buoyancy). Many forms of marine transport make use of planing, including fast ferries, racing boats, floatplanes, flying boats, seaplanes, and water skis. Most surfboards are planing or semi-planing hulls. Beyond planing, fast vessel designs have seen a transition to hydrofoil designs. History The earliest documented planing sailboat was a proa built in 1898 by Commodore Ralph Munroe. It was capable of speeds of more than twice the hull speed. Planing a sailing dinghy was first popularised by Uffa Fox in Britain. In 1928 Fox introduced planing to the racing world in his International 14 dinghy, ''Avenger''. That year he gained 52 first places, 2 seconds, and 3 third places out of 57 race starts. This performance was noticed by other designers who further developed them. Over the years many dinghies have acquired ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seaplane
A seaplane is a powered fixed-wing aircraft capable of taking off and landing (alighting) on water.Gunston, "The Cambridge Aerospace Dictionary", 2009. Seaplanes are usually divided into two categories based on their technological characteristics: floatplanes and flying boats; the latter are generally far larger and can carry far more. Seaplanes that can also take off and land on airfields are in a subclass called amphibious aircraft, or amphibians. Seaplanes were sometimes called ''hydroplanes'', but currently this term applies instead to motor-powered watercraft that use the technique of hydrodynamic lift to skim the surface of water when running at speed. The use of seaplanes gradually tapered off after World War II, partially because of the investments in airports during the war but mainly because landplanes were less constrained by weather conditions that could result in sea states being too high to operate seaplanes while landplanes could continue to operate.

Diving Plane
Diving planes, also known as hydroplanes, are control surfaces found on a submarine which allow the vessel to pitch its bow and stern up or down to assist in the process of submerging or surfacing the boat, as well as controlling depth when submerged. Bow and stern planes Diving planes are usually fitted in two pairs, the '' bow planes'' at the front of the submarine and the ''stern planes'' at the rear. The stern planes function in much the same way as an aircraft's elevator. As the planes are a long distance fore-and-aft from the hull's centre of buoyancy, they introduce a pitching moment. Ballast tanks within the submarine adjust buoyancy to be neutral, making the boat controllable. The position of the planes controls the pitch of the boat and, with the forward motion of the boat, this controls depth. If not carefully controlled, this could lead to a 'porpoising' motion whereby the planesman continually hunts for a stable combination of depth and pitch. For easier berthi ...

Hydroblading
A hydroblade is a figure skating edge move or connecting step in which a skater glides on a deep edge with the body stretched in a very low position, almost touching the ice. Several variations in position are possible, but one commonly performed by singles skaters is on a back inside edge with the knee of the skating leg deeply bent, the free leg crossed behind and extended outside the circle, and the upper body leaning into the circle with two, one, or no hands skimming the ice. History Although they did not invent the element, it was popularized in the early 1990s by the Canadian ice dance Ice dance (sometimes referred to as ice dancing) is a discipline of figure skating that historically draws from ballroom dancing. It joined the World Figure Skating Championships in 1952, and became a Winter Olympic Games medal sport in 1976.
