Wing-variable vertical take-off and landing self-grabbing and loading aircraft

Abstract

The invention provides a wing-variable vertical take-off and landing self-grabbing aircraft, and relates to the technical field of aircrafts. The invention aims to solve the problems of flight range, vertical take-off and landing, autonomous cargo grabbing and loading and folding of the aircraft. The aircraft comprises a fuselage, wing root sections, a wing tip section, rotor assemblies, a swing paddle hinge, an orientation hinge, a wing root hinge, a wing middle hinge and a grabbing and loading device, the fuselage is composed of a middle half cylinder and identical streamline half bodies at the two ends, and the plane cylinder wall faces downwards; the wing root sections are symmetrically mounted on the left side and the right side of the fuselage through the left wing root hinge and the right wing root hinge; the wing tip section is provided with a foot, and the root of the foot is installed at the tail end of the wing root section through the wing middle hinge. The rotor assemblies are divided into a left front group, a left rear group, a right front group and a right rear group, and each group can perform swing angle tilting around the swing paddle hinge and the orientation hinge, so that continuous flight, hovering, vertical take-off and landing and folding are realized. The grabbing and loading device is arranged below the belly of the fuselage. The aircraft is suitable for cargo handling.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a variable-wing vertical take-off and landing self-grabbing aircraft. Background technique [0002] Traditional fixed-wing aircraft have the advantages of fast speed and long range, but at the same time have the disadvantage of requiring a runway site for takeoff and landing. The traditional multi-rotor aircraft has the advantages of vertical take-off and landing and flexible flight, but at the same time has the disadvantages of slow speed and short flight range. The existing fixed-wing vertical take-off and landing aircraft combines the characteristics of multi-rotor aircraft that can take off and land vertically and the ultra-long range and large load capacity of fixed-wing aircraft, and is widely used in fields such as transportation, surveying and mapping, agriculture, and disaster relief. In related technologies, fixed-wing vertical take-off and landing aircraft have large...
