Small flapping wing type ducted aircraft

Abstract

The invention relates to a small flapping wing type ducted aircraft. A flapping wing mechanism and ducted engines are organically combined, and three ducted engines and the flapping wing mechanism provide power commonly, so that multi-pose and flexible flight can be achieved; the flapping wing mechanism adopts a crank rocker based deformation mechanism to realize bionic flapping wing motion; the three ducted engines are in triangular pneumatic layout, the ducted engine positioned in the middle is a main ducted engine and is immobilized; the other two ducted engines positioned at sides are small ducted engines and can rotate obliquely; the aircraft can realize vertical take-off and landing, and at the moment, the three ducted engines can provide power in a vertical direction; when the flapping wing is immobilized at a horizontal position, the two small ducted engines obliquely rotate to a horizontal position and provide pushing force in a horizontal direction to realize high-speed level flight or steering of the aircraft; and the aircraft can cruise slowly when in a flapping wing movement manner. The small flapping wing type ducted aircraft adopts combination driving and multi-pose flight, so that the flight efficiency and the motility of the aircraft can be greatly improved.

Description

technical field [0001] The invention relates to a small bionic aircraft, in particular to a novel aircraft which combines a bionic flapping wing structure with a tiltable ducted engine. Background technique [0002] Ordinary fixed-wing aircraft have the function of high-speed navigation, but they cannot take off and land vertically and hover; rotorcraft can take off and land vertically, but they cannot fly at high speed. The tiltable ducted aircraft solves the above problems, and realizes that the aircraft can take off and land vertically and fly horizontally at high speed. This type of ducted aircraft has the characteristics of high thrust and high speed, but its outstanding disadvantages are high noise, low efficiency, and short endurance time. In comparison, the flapping-wing aircraft has the advantages of high efficiency and low noise, but its disadvantages of low speed and low thrust also limit its application. Contents of the invention [0003] In view of the above...
