The story begins with the history of Saunders Roe and their involvement as a result of the discovery by Christopher Cockerell in that big weights could be supported on a cushion of low pressure air and that the concept could be practically has already been written about Christopher Cockerell, later Sir Christopher, and the development of the hovercraft by Saunders Roe, as well as the 5/5(11).

Early air cushion vehicles were conceived with the object of drag reduction for a marine craft. The concept of injecting lubricating air over the wetted surface was replaced by the use of a thicker air cushion.

The chapter deals with the air cushion theory from early research and discusses the flow rate coefficient method. This definitive text describes the theory and design both of Air Cushion Vehicles (ACV) and Surface Effect Ships (SES).

It begins by introducing hovercraft types and their development and application throughout the world in the last three decades, before going on to discuss the theoretical aspects of ACV and SES craft covering their hovering performance, dynamic trim over calm water.

In an American, William W. Humphreys, patented an idea - a 'Pneumatic Spring for Vehicles'. The design consisted of a left and right air spring longitudinally channeled nearly the length of the vehicle. The channels were concaved to receive two long pneumatic cushions.

It is the first production car built with the Air Cushion Restraint System (ACRS) option that was intended for retail sale. On December 6,the first Buick equipped with ACRS was completed at Factory 4 in Flint, Michigan.

It was a Electra Limited that was painted Crystal Lake Blue Metallic. Linderer's airbag (German patent #) was based on a compressed air system, either released by bumper contact or by the driver. Hetrick received a patent in (U.S. #2,) for what he called a "safety cushion assembly for automotive vehicles," also based on compressed air.

air-cushion vehicle (ACV), craft designed to travel close to but above ground or water. It is also called a ground-effect machine or Hovercraft. These vehicles are supported in various ways. Air cushion vehicles are generally of two basic types, one type having a flexible or partially flexible skirt to contain lifting air, which leaks out under the skirt and can be controlled to some.

Air Cushion Vehicles (ACVs) have been developed with either flexible skirts or having fixed side walls with flexible skirts located at the bow and stern of the craft. They have been produced in a wide range of sizes as shown in Fig.

for several fully flexible skirt hovercraft. Furthermore, this figure vividly contrasts the size difference. He started sketching designs for his “safety cushion assembly for automotive vehicles” and patented it in His design included an underhood tank for compressed air and front passenger inflatable bags located on the steering wheel, the middle of the dashboard and the glove compartment.

The Patrol Air Cushion Vehicle (PACV), also known as the Air Cushion Vehicle (ACV) in Army and Coast Guard service, was a United States Navy and Army hovercraft used as a patrol boat in marshy and riverine areas during the Vietnam War between and Six hovercraft were built, three for the Army and three for the Navy.

Air cushion vehicles or also called hovercraft are capable of traveling across both land and water. A large portion of the weight is supported by a cushion of slow moving, high pressure air developed around the craft resulting this vehicle to float but just near the Earth’s surface.

Since air cushion vehicles travel over surfaces, they have. History of the Russian military; Inofficial tests of the newest air defense missile system Bagulnik (domestic variant of the Sosna-R to replace Strela) were successfully completed.

Other articles where Air-cushion train is discussed: air-cushion machine: Air-cushion trains: Once air-cushion suspension was proved practical in Hovercraft, the system was quickly applied to other forms of transport, and it soon became clear that a tracked vehicle, similar to a train or monorail, would benefit considerably from the lack of friction inherent in.

Air-cushion machine - Air-cushion machine - ACV operation: Operations on which air-cushion vehicles have been used have been largely confined to commercial passenger-carrying ferry services across stretches of water, varying between 3 and 25 miles (5 to 40 kilometres) wide, and to certain military operations.
