How does the hovercraft come from and what is the principle of how to get off the ground?
The greatest advantage of hovercraft is that it reduces the resistance of navigation because the air resistance is much smaller than the water resistance. Therefore, a higher speed can be achieved
The hovercraft is higher than the atmospheric air in the bottom and the support surface (water or land) is formed between the "air cushion", usually known as the air cushion, and the air cushion support the weight of the hull, so that all or part of the hull from the supporting surface of a new high-speed ship
Second, hovercraft is completely amphibious and suitable for navigating in shallow and shallow waters. The power of the hovercraft's power unit is mainly used for two parts: the power supplied to the air cushion by a cushion lift fan, which is called pad power. The other part is the power required for navigation, called propulsive power.
