Hovercraft - Ultimate Amphibious Machine
Subscribe to Naked Science - http://goo.gl/wpc2Q1 Every Wednesday we present a new video, so join us to see the truth laid bare... This machine breaks all the rules, it can penetrate some of the toughest terrains on earth, over land, over water, from the polar ice, to the rapids of the Amazon. This is the ultimate frictionless floating machine, the incredible hovercraft. A hovercraft, also known as an air-cushion vehicle or ACV, is a craft capable of travelling over land, water, mud or ice and other surfaces. Hovercraft are hybrid vessels operated by a pilot as an aircraft rather than a captain as a marine vessel. Hovercraft use blowers to produce a large volume of air below the hull that is slightly above atmospheric pressure. The pressure difference between the higher pressure air below the hull and lower pressure ambient air above it produces lift, which causes the hull to float above the running surface. For stability reasons, the air is typically blown through slots or holes around the outside of a disk or oval shaped platform, giving most hovercraft a characteristic rounded-rectangle shape. Typically this cushion is contained within a flexible "skirt", which allows the vehicle to travel over small obstructions without damage. The first practical design for hovercraft derived from a British invention in the 1950s to 1960s. They are now used throughout the world as specialised transports in disaster relief, coastguard, military and survey applications as well as for sport or passenger service. Very large versions have been used to transport hundreds of people and vehicles across the English Channel whilst others have military applications used to transport tanks, soldiers and large equipment in hostile environments and terrain.
Navy LCAC Hovercrafts Docking on USS Kearsarge
Marines assigned to Weapons Co., Battalion Landing Team (BLT) 3/2, 26th Marine Expeditionary Unit (MEU), are transported, via landing craft, air cushion (LCAC), from the USS Kearsarge (LHD 3) to a simulated raid mission and back, near Onslow Beach, N.C. The 26th MEU is conducting Composite Training Unit Exercise, the final phase of a six-month pre-deployment training program. The 26th MEU operates continuously across the globe, providing the president and unified combatant commanders with a forward-deployed, sea-based quick reaction force. The MEU is a Marine Air-Ground Task Force capable of conducting amphibious operations, crisis response and limited contingency operations. Produced by U.S. Marine Corps motion media. Video by Cpl.

LCAC Military Hovercraft - No Beach Out of Reach
Subscribe to Naked Science - http://goo.gl/wpc2Q1 Every Wednesday we present a new video, so join us to see the truth laid bare... This is the state-of-the-art hovercraft known as the LCAC, or “Landing Craft Air Cushion”. A class of air-cushion vehicle used as landing craft by the United States Navy's Assault Craft Units and the Japan Maritime Self-Defense Force (JMSDF). The LCACs weigh 100 tonnes each and carry four gas turbine engines of 4,000 horsepower, a total of 16,000 horsepower. They transport weapons systems, equipment, cargo and personnel of the assault elements of the Marine Air / Ground Task Force both from ship to shore and across the beach. They can carry up to 75 tonnes of equipment over 20 miles. Their moto is “No Beach Out of Reach”. Clip from the documentary “Extreme Machines - Hovercraft”.
