Abstract

The invention discloses a single-lift-force duct vertical take-off and landing aircraft based on a tilting duct and relates to an aircraft. The single-lift-force duct vertical take-off and landing aircraft comprises an aircraft body, two wings, N tilting duct fans, a single-lift-force duct fan and a duct cover. The wings are arranged on the two sides of the rear middle portion of the aircraft bodycorrespondingly, and each wing is formed by means of the method that the wing stretches outwards from the side portion. Each set of tilting duct fans is mounted on the two sides of the aircraft bodycorrespondingly, and each tilting duct fan is rotatably connected with the aircraft body through a corresponding connecting piece. The single-lift-force duct fan is inlaid among the aircraft body andthe two wings. The duct cover is mounted on the upper portion of the single-lift-force duct fan and can be opened or closed. Through the tilting duct fans, posture control in the vertical take-off andlanding stages and propulsion in the horizontal flying stage are achieved. Through the single-lift-force duct fan, main life force in the vertical take-off and landing stages is provided, vertical take-off and landing are achieved, and the lift force and the posture control part are decoupled, so that the complexity of the power characteristic is lowered, and the reliability is improved.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a tilting duct-based single-lift duct vertical take-off and landing aircraft. Background technique [0002] Vertical take-off and landing aircraft usually refers to a type of aircraft that can take off and land vertically like a helicopter, has the ability to hover, and can fly horizontally in the manner of a fixed-wing aircraft. Benefiting from the advantages of convenient take-off and landing and high flight efficiency, vertical take-off and landing aircraft have important application value in the military. There are three types of vertical take-off and landing aircraft: rotor-type vertical take-off and landing aircraft, tilting-type vertical take-off and landing aircraft, and tailseat type vertical take-off and landing aircraft. The following will be described with a tilting vertical take-off and landing aircraft. [0003] Existing tilting vertical take-off and landing aircraft inclu...
