Embodiment Construction

[0025] As shown in the figure, this embodiment provides a foldable variable configuration UAV, including a fuselage 10, two pairs of wings 20 rotatably mounted on the fuselage, and forward propellers mounted on the head of the fuselage. 30. The empennage 40 installed at the tail of the fuselage and the ducted fan 50 arranged on the wing, the wing can be driven to rotate approximately parallel to the fuselage to form a folded state or approximately perpendicular to the fuselage to form an unfolded state or to be in an unfolded state with the fuselage The body is oblique to form a half-expanded state.

[0026] A pair of wings here refers to two pairs of wings installed on both sides of the fuselage, and a pair of wings are symmetrically arranged on both sides of the fuselage; approximately parallel means that the wings are parallel to the length direction of the fuselage And a deviation of ±15° is allowed. The corresponding approximate vertical means that the wing is perpendicul...

Abstract

The invention discloses a foldable variable-structure unmanned aerial vehicle which comprises a fuselage, two pairs of wings rotatably mounted on the fuselage, a front propeller mounted at the head of the fuselage, an empennage mounted at the tail of the fuselage and ducted fans arranged on the wings. The wings can be driven to rotate to be approximately parallel to the fuselage to form a folded state or approximately perpendicular to the fuselage to form an unfolded state or obliquely intersect with the fuselage to form a semi-unfolded state. According to the unmanned aerial vehicle, the landing mode and the flight mode can be switched in a self-adaptive mode according to the terrain, the unmanned aerial vehicle can adapt to complex terrains, stable flight in various application scenes can be achieved, and operation is more flexible; when the wings of the structure are folded, the wings are horizontally stored to the two sides of the aircraft body, and the landing occupied area of the whole aircraft can be greatly reduced; the unmanned aerial vehicle with the structure is relatively simple in structure, lightweight design is favorably realized, energy consumption is reduced, the fuselage size of the unmanned aerial vehicle is favorably reduced, and a high space utilization rate is realized.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a foldable and variable configuration drone. Background technique [0002] Unmanned aircraft, referred to as unmanned aerial vehicle, is an unmanned aircraft controlled by radio remote control equipment and its own program control device. UAVs are widely used in various scenarios, such as aerial photography, crop monitoring, vegetation protection, selfie, express delivery, disaster rescue, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspection, and film and television shooting, etc. [0003] Existing UAVs are usually divided into fixed-wing UAVs and multi-rotor UAVs. Fixed-wing UAVs require a longer runway, while multi-rotor UAVs and helicopters require larger aprons. Their take-off and landing all require a specific site, which cannot adapt to take-off and landing on more complex terrain such as cities. [0004] Therefore,...
