The latter chapters describe a design methodology, including design criteria and standard methods for estimating craft performance, lift system design, skirt design, hull structure, propulsion systems and power unit selection. Much technical information, data, and references to further work on hovercraft and SES design is provided.

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 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. The first practical design for hovercraft was derived from a British invention in the s to s. 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.

At zero speed in still air equation The Kj available from typical cushion systems is shown in Fig. At zero speed, the discharge coefficient for the skirt 'nozzle' reduces the available thrust. Air propellers a propeller or ducted axial fan, which may be designed for a given forward speed. Cushion system fans are selected for maximum efficiency when at mean cushion flow, at cushion pressure.

У нее резко запершило в горле, и в поисках выхода она бросилась к двери. Переступив порог, она вовремя успела ухватиться за дверную раму и лишь благодаря этому удержалась на ногах: лестница исчезла, превратившись в искореженный раскаленный металл.

Джабба тяжко вздохнул и повернулся к экрану. - Не знаю. Все зависит от того, что ударило в голову автору.  - Он привлек внимание к тексту на экране.

Мне кажется, я должен вам сказать… что это не случайный набор букв. Все на подиуме воскликнули: - Что. В голосе Беккера слышались извиняющиеся нотки: - Простите, но это определенно осмысленные слова.
