Problems solved by technology

[0003] Traditional fixed-wing aircraft rely on the fixed wing to generate lift at a relative speed to the air. Although the operation is simple, it cannot take off and land vertically, hover and fly backwards. It has high requirements for the take-off and landing site and requires a long and flat runway ; Although traditional helicopters can take off and land vertically, the blades of the main rotor rotate while advancing with the body when flying forward. The combination of these two movements makes the relative air velocity of the blades asymmetrical on the left and right sides of the rotation plane , to be balanced by the waving movement of the main rotor, it is difficult to control and trim, its structure is complex, and its maneuverability and safety are not high.

example 1

[0026] Example 1, using two devices of the present invention with the same structure, looking straight ahead from the rear of the reciprocating-wing aircraft, the two devices are symmetrically arranged on the left and right sides of the upper fuselage of the reciprocating-wing aircraft, the rotating disks of the two devices are inward, and the reciprocating wing Outside, the rotating disks of the two devices are in the same horizontal plane, and the two devices all generate upward lift under the drive of power. The two devices can be driven in synchronous linkage or independently, and have good maneuverability. The linkage of the two devices can be realized by the teeth on the outer periphery of the turntables of the two devices meshing with each other. In this case, the two devices move synchronously and symmetrically to facilitate trimming. When the reciprocating wing of the device on the right side of the fuselage moves to the left, the reciprocating wing of the device on th...

example 2

[0027] Example 2, use four devices of the present invention with the same structure to be arranged in a matrix around the same reciprocating-wing aircraft to form a flying platform. The four devices are symmetrical in pairs, and the rotating disks of the four devices are all close to the geometric center of the reciprocating-wing aircraft. Their reciprocating wings are far away from the geometric center of the reciprocating wing aircraft. The upper surfaces of the turntables of the four devices are in the same horizontal plane. The four devices are driven independently. The flight of the reciprocating wing aircraft can be controlled by adjusting the reciprocating frequency of the four devices. Attitude and maneuverability are good.

example 3

[0028] Example 3, the device of the present invention is conveniently applied to the flying car. Two devices of the present invention are symmetrically arranged on the left and right sides of the top of the flying car. above the window. In the car mode, the reciprocating wings are closely attached to the sides of the vehicle body without occupying space; in the flight mode, the power of the engine is transmitted to the turntable shaft through the transmission shaft, and both devices generate sufficient lift under the drive of power.

Abstract

The invention relates to a moving guide frame type reciprocating airfoil lift force generating device which belongs to the technical field of aircrafts and models thereof. The reciprocating airfoil lift force generating device comprises a rotating disk, a rotating disk shaft, a rotating disk handle, a connecting rod slide block, a moving guide frame, reciprocating wings, an inner attack angle positioning rod and an outer attack angle positioning rod, wherein the moving guide frame comprises a connecting rod with a slot, a front guide rod, a reciprocating wing drive shaft and a rear guide rod; the reciprocating wing drive shaft passes through through-holes of the reciprocating wings and is arranged on the front guide rod and the rear guide rod; the rotating disk is driven to rotate by power to ensure that the moving guide frame does reciprocating translational motions; and the reciprocating wings are driven by the reciprocating wing drive shaft to do reciprocating motions so as to generate upward lift force. The reciprocating airfoil lift force generating device has the advantages of simple structure, convenience in operation and control and higher efficiency and can be used as a lift force device for an aircraft and a model thereof.

Description

technical field [0001] A mobile pedestal type reciprocating wing lift generating device relates to the technical field of aircraft and its models, and can be widely used in the fields of transportation, military affairs, agriculture and forestry, sports entertainment, toys and the like. Background technique [0002] Humans desire to fly freely in the air by driving an aircraft that is simple in structure, safe, reliable and easy to maneuver. [0003] Traditional fixed-wing aircraft rely on the fixed wing to generate lift at a relative speed to the air. Although the operation is simple, it cannot take off and land vertically, hover and fly backwards. It has high requirements for the take-off and landing site and requires a long and flat runway ; Although traditional helicopters can take off and land vertically, the blades of the main rotor rotate while advancing with the body when flying forward. The combination of these two movements makes the relative air velocity of the bl...
