A V-hull, is the shape of a boat or ship in which the contours of the hull come in a straight line to the keel. [1] V-hull designs are usually used in smaller boats and are useful in providing space for ballast inside the boat.
They are usually displacement hulls. V or arc-bottom chine boats have a V shape between 6° and 23°. This is called the deadrise angle. The flatter shape of a 6-degree hull will plane with less wind or a lower-horsepower engine but will pound more in waves. The deep V form (between 18 and 23 degrees) is only suited to high-powered planing ...
The V-hull on the Marine Personnel Carrier (highlighted in green) protects well against IEDs, but raises the center of mass, increasing the likelihood of rollovers.. The V-hull is a type of vehicle armor design used on wheeled armored personnel carriers (APCs), infantry mobility vehicles, infantry fighting vehicles (IFVs) and MRAPs.
A padded V-hull is a hull shape found on both pure race boats and standard recreational craft. A variation of the more common V-hull , which has a V-section throughout the length of the vessel, a padded V-hull has a V-section at the bows and the forward part of the keel which then segues into a flat area typically 0.15 metres (5.9 in) to 0.25 ...
1919 Napier Lion II aircraft engine with three cylinder banks. Any design of motor/engine,be it a V or a boxer can be called an "in-line" if it's mounted in-line with the frame/chassis and in-line with the direction of travel of the vehicle.When the motor/engine is across the frame/chassis this is called a TRANSVERSE motor.Cylinder arrangement is not in the description of how the motor/engine ...
The Marlin was designed as a gull-winged aircraft to place the engines and propellers high above the spray. Power was provided by two Wright R-3350 radial engines . The rear hull did not lift sharply from the water at the tail, instead rising up steadily, a Martin innovation; this gave the aircraft a longer base of flotation and reduced ...
the engine can be mounted in a more space-efficient position. the position of the hull's centre of gravity may be optimised, In all cases, maintenance may be more difficult with a V-drive, since the main propshaft beneath the engine may be somewhat inaccessible. Also, when installing a V-drive, it can be a difficult process to ensure accurate ...
Some engines have used a V-angle of 180 degrees (the same angle as a flat engine), such as several Ferrari V12 engines. [ 7 ] [ 8 ] At the other end of the scale, the 1922-1976 Lancia V4 engine and the 1991–present Volkswagen VR6 engine use V-angles as small as 10 degrees, along with a single cylinder head used by both banks of cylinders.
