The Landing Craft, Air Cushion (LCAC) is a high-speed, over-the-beach, fully amphibious landing craft capable of carrying a ton payload. During the advanced development . The air cushion holds it high above waves and land obstructions, making the craft superbly amphibious (equally capable of traveling on land or water or gliding smoothly from one to the other). That's why military hovercraft, designed for swift beach landings, are often called LCACs (Landing Craft Air Cushion).
Air cushion technology allows this vehicle to reach more than 70 percent of the world's coastline, while only about 15 percent of that coastline is accessible by conventional landing craft. Hovercraft float on a cushion of air that has been forced under the craft by a fan. This causes the craft to rise or lift. The amount of lift can range from 6" to " (mm to 2,mm) depending on the size of the hovercraft.
This report provides an overview of the research conducted at the Naval Aerospace Medical Research Laboratory (NAMRL) to improve Landing Craft Air Cushion (LCAC) crew selection. The report includes background information, crew task analysis procedures, identification of critical skills, and the development of selection tests. existing crafts. For this reason, a statistical database has been created using publicly available information. A regression analysis has been performed using the data collected and the trend lines for every case have been derived. For the validation of the code, LCAC (Landing Craft Air Cushion) is used as the reference vehicle.

This book examines the air cushion craft in its various forms and accumulates the results of those who have helped in its development, in order to determine the present state-of-the-art. Naturally, on a subject as broad as this and containing many important details, the study frequently must be selective and sometimes qualitative.
Theory and Design of Air Cushion Craft: Yun, Liang, Bliault, Alan: : by: Get this from a library. Air cushion craft development. [Peter J Mantle; David W. Taylor Naval Ship Research and Development Center. Systems Development Department.]. Development of the air cushion theory is closely related to the development of hovercrafts themselves, particularly of flexible skirts.
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.
A technical summary is given of the development of air cushion craft from their inception to the present day. The designation 'air cushion craft' encompasses any craft that relies on a cushion of air for a significant part of its support and operates in close proximity to the surface.

hovercraft. Powerful blowers are used to force air into the volume underneath the craft. The hovercraft’s skirt, which is labelled in Figure 3, traps much of the air being forced under the craft and creates a ‘cushion’ of air pressure.
The skirt also helps to force air against the surface directly below the hovercraft. A hovercraft, also known as an air-cushion vehicle or ACV, is an amphibious craft capable of travelling over land, water, mud, ice, and other surfaces.
Hovercraft use blowers to produce a large volume of air below the hull, or air cushion, that is slightly above atmospheric pressure. The pressure difference between the higher pressure air below the hull and lower pressure ambient air. A hovercraft uses an air compressor to provide an air cushion contained within a skirt fastened around the craft.
The mass of the craft is kg, and the craft has a pressurized area of 3 m x 8 m, The average clearance above the water surface is 3 cm. The velocity of the air is low at the center of the cushion. Yun L, Bliault A () Air cushion craft.

Type. Air cushion technology at home and abroad has been applied for many years; air cushion technology can be used for the overall movement of drilling equipment. It can be adopted using a non-self-propelled loaded large air cushion platform, and then matched with the appropriate running gear and a large air cushion platform supporting smooth movement for all drilling .WING-IN-GROUND CRAFT.
A wing-in-ground (WIG) craft is defined as a vessel capable of operating completely above the surface of the water on a dynamic air cushion created by aerodynamic lift due to the ground effect between the vessel and the water's surface.
WIG craft are capable of operating at speeds in excess of knots.Search the world's most comprehensive index of full-text books. My library.
