Description

Ferry airship

Technical Field

The invention belongs to a water surface take-off and landing aircraft, in particular to a ferry airship for providing a take-off and landing platform for an aircraft on water surface.

Background

When the airplane takes off and lands on the land, a special runway and peripheral dispatching facilities need to be constructed on an airport. However, the site selection of the airport and the construction of the runway are not only influenced by the landform and the terrain, but also have very high construction and operation costs, so that the application range of the airplane is greatly limited. The development of seaplanes and aircraft carriers has solved the problem of airport restrictions.

Seaplanes are not comparable to airplanes in terms of speed and endurance due to their special hull structure and large weight.

The aircraft carrier is an effective way for realizing take-off and landing of the aircraft on the sea, but the aircraft carrier is high in manufacturing cost, huge in construction difficulty and limited in the number of carried shipboard aircraft.

Aiming at the problems, no simple, reliable and economic solution exists at present.
