SUMMERY OF THE UTILITY MODEL

The utility model discloses it is lower to solve prior art gyroplane flight speed, and the lift is less, and the less problem of payload provides a gyroplane with collapsible telescopic fixed wing.

The above technical problem of the present invention can be solved by the following technical solutions: the utility model provides a gyroplane with collapsible telescopic fixed wing, includes gyroplane body, a plurality of to the wing, is used for making the first joint motor that the wing was put perpendicularly or level and be used for making the wing is along horizontal axial pivoted second joint motor, connect through first joint motor and second joint motor between wing and the aircraft body.

The utility model relates to a gyroplane with collapsible telescopic fixed wing, gyroplane are when vertical lift, shut down state, and the wing is the contraction state, puts perpendicularly. When the rotor plane flies flatly, the wings are extended through the telescopic mechanism, the wings are placed in a horizontal state through the first joint motor, and the wings rotate around the horizontal axial direction through the second joint motor, so that the flying actions such as climbing, steering, decelerating and the like are realized. The wings are extended when in a flat flying state, so that the aircraft can obtain vertical lift force additionally, the load capacity of the rotor type aircraft is improved, the inclination angle between the rotor wing of the aircraft and the horizontal direction is increased through axial rotation, larger forward thrust can be obtained, and the flying speed is improved.

As a preferred scheme, the wing comprises a telescopic mechanism and a wing shell, and the telescopic mechanism is arranged in the wing shell.

As a preferable scheme, the wing shell is formed by combining a plurality of outer skins which have the same cross section shape and sequentially reduced sizes.

As a preferred scheme, the telescopic mechanism is formed by combining a plurality of hydraulic cylinders which are sequentially nested in size.

As a preferable scheme, the outer skin is correspondingly provided with a hydraulic cylinder, so that the outer skin of each wing except the outer skin close to the airplane body can stretch, the stretching of the outer skin is driven by the stretching of the hydraulic cylinder, and the stretching of the wing is realized.

Preferably, the wings are symmetrically arranged on two sides of the airplane body or on the lower portion of the airplane body, and balance and stability are achieved.

As a preferable scheme, the cross section of the wing is flat at the bottom and convex at the top, so that a larger lifting force can be obtained in the flying process of the airplane.

Therefore, the utility model has the advantages that: simple structure and low manufacturing difficulty. The rotary wing aircraft can obtain extra vertical lift force, the load capacity of the rotary wing aircraft is improved, larger forward thrust is obtained by increasing the inclination angle between the rotary wing of the aircraft and the horizontal direction, and the flying speed is effectively improved.

Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

Example (b):

the rotor plane with the foldable telescopic fixed wings comprises a rotor plane body 1, a plurality of pairs of wings 2, a first joint motor 3 for enabling the wings to be vertically or horizontally arranged and a second joint motor 4 for enabling the wings to rotate along the horizontal axial direction, wherein the wings and the plane body are connected through the first joint motor and the second joint motor, as shown in the attached

drawings

1, 2 and 3.

The utility model relates to a gyroplane with collapsible telescopic fixed wing, this gyroplane are when vertical lift, shut down state, and the wing is the contraction state, puts perpendicularly. When the rotor plane flies flatly, the wings are extended through the telescopic mechanism, the wings are placed in a horizontal state through the first joint motor, and the wings rotate around the horizontal axial direction through the second joint motor, so that the flying actions such as climbing, steering, decelerating and the like are realized. The wings are extended when in a flat flying state, so that the aircraft can obtain vertical lift force additionally, the load capacity of the rotor type aircraft is improved, the inclination angle between the rotor wing of the aircraft and the horizontal direction is increased through axial rotation, larger forward thrust can be obtained, and the flying speed is improved.

The wing comprises a telescopic mechanism and a wing shell, and the telescopic mechanism is arranged in the wing shell.

The wing shell is formed by combining a plurality of outer skins which have the same cross section shapes and sequentially reduced sizes.

The telescopic mechanism is formed by combining a plurality of hydraulic cylinders which are sequentially nested in size.

The outer skin is correspondingly provided with the hydraulic cylinder 5, so that the outer skin 6 of each wing except the outer skin close to the airplane body can stretch out and draw back, the outer skin is driven to stretch out and draw back through the stretching of the hydraulic cylinder, and the stretching of the wings is realized.

The wings are symmetrically arranged on two sides of the airplane body or on the lower portion of the airplane body, and balance and stability are achieved.

The cross section of the wing is flat at the bottom and convex at the top, so that the airplane can obtain larger lifting force in the flying process.
