Three-airfoil layout vertical take-off and landing general aircraft

Abstract

The invention discloses a three-airfoil layout vertical take-off and landing general aircraft, which comprises a wing, a fuselage, a tail wing, a duck wing, a power device, a connecting device, a propulsion system and a duck wing coaxial rotating device. The power device comprises a first power device, a second power device, a third power device and a fourth power device; the top of the fuselage is provided with the duck wing. Both ends of the duck wing are respectively provided with the first power device and the second power device. Both sides of the outer part of the fuselage and below theduck wing are respectively provided with wings. A connecting device is arranged below the wing. Both sides of the connecting device are respectively provided with the third power device and the fourthpower device. The bottom of the fuselage is provided with the tail wing. The control device is arranged inside the fuselage. The aircraft solves the problems of insufficient lift force, without direct force control, low static instability, low take-off and landing performance, poor safety reliability, heavy wing load, low take-off load and high use cost of the general aircraft.

Description

technical field [0001] The invention relates to the field of general-purpose aircraft, in particular to a vertical take-off and landing general-purpose aircraft with three-plane layout. Background technique [0002] The take-off and landing of general-purpose aircraft have conditional constraints, such as the need for a wide take-off runway, special site requirements, and a larger take-off site; general-purpose aircraft power devices are mainly turboprop engines and turboshaft engines with single power. Due to the limitation of power, the power cannot be tilted. [0003] The conventional layout of a general-purpose aircraft refers to the layout of the wing and the empennage. The conventional layout plus a horizontal front wing constitutes a three-plane layout, which not only can still maintain the beneficial interference of the canard detachment vortex at a short distance, but also improves the control efficiency and reduces the trim resistance by simultaneously operating t...
