Vertical take-off and landing aircraft with layouts of tilting ducts and connecting wings

Abstract

The invention discloses a vertical take-off and landing aircraft with layouts of tilting ducts and connecting wings. The vertical take-off and landing aircraft comprises a fuselage, tilting duct fans,the connecting wings, undercarriages and an empennage trim fan. The connecting wings are divided into the front wings and the rear wings; the tilting duct fans are arranged in a bilateral symmetry mode and connected with the middle of the fuselage through tilting structures, and an engine arranged inside the fuselage drives the tilting duct fans through transmission mechanisms arranged in the tilting structures so that upward lift force or forward thrust can be provided for the aircraft; the front wing faces and the rear wing faces of the connecting wing structures have the height difference,wing roots of the rear rings are connected to a vertical empennage, wing tips of the rear wings are connected to the middle sections of the front wings, and full-aircraft lift force is provided at the flat flight stage; and the layout of the tilting duct fans and the layout of the connecting wings are combined, and the wing structures are complete. The vertical take-off and landing aircraft can take off and land vertically and hover in the air and can also take off and land in a sliding mode and cruise at a high speed like a fixed wing aircraft; the duct fan propelling mode is quiet and efficient, and the engine is mounted inside the fuselage; and the aircraft overall layout is compact and reasonable, a transmission device is precise and simple, safety and reliability are achieved, and thus high application value is achieved.

Description

technical field [0001] The invention relates to a vertical take-off and landing unmanned aerial vehicle with a tilting double-duct connecting wing layout, and belongs to the technical field of unmanned aerial vehicle of aviation vehicle technology. Background technique [0002] Tilt-rotor vertical take-off and landing fixed-wing aircraft has both vertical take-off and landing capabilities and horizontal flight capabilities. It is mainly used in complex take-off and landing environments lacking airport support, and has rapid task response capabilities. [0003] At present, the existing thrust-oriented vertical take-off and landing fixed-wing UAVs use multi-rotor systems to provide the pulling force during the vertical take-off and landing stage, and switch to another power system during the level flight stage. The mass of the aircraft is mostly below 80kg, and the payload is 6kg. the following. For example, a fixed-wing unmanned aerial vehicle with vertical take-off and land...

Problems solved by technology

As announced by the notification number CN106167096A, a kind of improved approximate horizontal rotation propeller flap increases the connecting wing aircraft, all the ducted propellers are arranged on the leading edge of the front wing, and the tail only has a trim fan in the opening of the fuselage , the leading edge fan will generate pitching moment that cannot be trimmed during vertical take-off and landing, so that the vertical attitude of the aircraft cannot be maintained
