Description

X wing unmanned aerial vehicle

Technical Field

The invention relates to the technical field of unmanned aerial vehicles, in particular to an X-wing unmanned aerial vehicle.

Background

Conventional fixed wing aircraft require a relatively long runway to achieve take-off and landing. Not only does this mean that large amounts of manpower, material resources and financial resources are required to build the airport, but also in wartime, the airport will become the first target of attack for enemy troops. Once an airport is destroyed, even powerful B2, F22, heroes have no practical place to use. The horizontal flight speed of a helicopter or a multi-rotor aircraft is much slower than that of a fixed-wing aircraft. In order to make an airplane break through the limitation of a runway and realize free take-off and landing, a vertical take-off and landing aircraft VTOL (vertical take-off and landing) is created in the middle of the 20 th century, which is a revolutionary idea.
