Working Detail
Hovercraft is one of the most unusual vehicles that you
can see. Moves on an air cushion of slightly pressurized air that makes it
easily overcomes any slight unevenness and obstacles. It can run on sand,
asphalt and the water are no problem for him or swamps and snow. They belong to
a group of amphibians. Since the air under the hovercraft is not changed in
transit between different surfaces (e.g. between sandy beaches and water) cannot
tell any difference. Hovercraft dynamics is more aircraft than ships and
automobiles.
Hovercraft floats on a cushion of air that is chased by a
propeller craft. After starting to lift the hovercraft and is ready to ride.
The size of stroke ranges from 15 cm in the smallest personal hovercraft to 2.8
meters for large transport machines. The air pocket under the hovercraft is
surrounded by plastic to air from leaking out from under the hovercraft.
Implementation of the mantle differ may be either in the form of a compact bag
or can be divided into individual cells - so-called segments. Most professional
hovercraft using segmented casing, because each piece is in transit through the
inequality diverges separately. It is very convenient, because the lifter loses
only a very small amount of air. After the hoist lifter can move
forward. It must provide a separate air operator, which takes a hovercraft.
Many of the vessels used to move a separate engine, but some have only one
engine for both functions - that is, for blowing air under the hovercraft and
also to move forward. In this case, the airflow split propeller, which in part
drives the flyer for floatability, while majority of the air is used to move
the hovercraft.
