Description

Technical Field

[0001] The invention belongs to the field of aircraft, and in particular relates to an adsorption-type variable-wing rotor aircraft. Background Art

[0002] Rotorcraft has the advantages of safety, low take-off and landing requirements, and simple operation. According to analysis, the highly symmetrical structure of rotorcraft is the safest of all aircraft. A person only needs about half a day to learn and can basically operate it independently. Therefore, rotorcraft has always been considered the most ideal choice for novice pilots or individual reconnaissance.

[0003] In the field of reconnaissance and eavesdropping, the aircraft is required to be adaptable to the environment, that is, to be able to take off and land and fly in harsh environments; the aircraft is also required to be secretive, that is, small in size, with low aerodynamic noise during flight and no noise during eavesdropping; it is also required to have endurance, that is, to be able to fly and eavesdrop for a long time; in addition, the aircraft is also required to be easy to control, convenient to transport, and low in cost. However, rotorcraft has the following disadvantages: the speed of rotorcraft is difficult to increase, the flexibility is poor, and the number of flight actions that can be realized is small; and due to low aerodynamic efficiency, the endurance of rotorcraft is poor. Summary of the invention

[0004] The present invention provides an adsorption-type variant rotorcraft, which solves the problem of poor endurance of the rotorcraft by using vacuum pressure difference adsorption technology, and the rotorcraft has the ability to deform and change shape, so that it can be better used in the fields of reconnaissance and eavesdropping.

[0005] To achieve the above objectives, the present invention adopts the following technical solutions:

[0006] A suction-type variant rotorcraft comprises: a fuselage 1, a rotor arm shaft 2, a rotor arm 3, a rotor 4, a rotor arm lower cover 5, and a rotor arm lower cover shaft 6; a plurality of rotor arms 3 are evenly mounted on the edge of an upper plane of the fuselage 1 through the rotor arm shaft 2, the rotor 4 is mounted inside the rotor arm 3, and a plurality of rotor arm lower covers 5 are evenly mounted on the edge of the bottom of the rotor arm 3 through the rotor arm lower cover shaft 6.

[0007] In the above structure, there are four rotor arms 3; each rotor arm 3 has four rotor arm lower covers 5; the material of the rotor arm 3 is carbon fiber; the top material of the rotor arm 3 is rubber; a camera 9 is installed on the lower surface of the fuselage 1, and several camera covers 7 are evenly installed on the edge of the lower surface of the fuselage 1 through the camera cover rotating shaft 10; there are four camera covers 7.

[0008] Beneficial effects: The present invention provides an adsorption-type variant rotorcraft, which not only utilizes the advantages of convenient take-off and landing and easy control of the rotorcraft, but also combines the vacuum pressure difference adsorption technology to make up for the disadvantage of poor endurance of the rotorcraft. At the same time, the rotorcraft of the present invention has the ability to deform and change, and has a transportation state, a flight state and an eavesdropping state, which respectively correspond to the functions of storage and transportation, take-off and landing, and reconnaissance and eavesdropping. When in the eavesdropping state, the aircraft can be adsorbed on the ceiling, which enhances the endurance of the aircraft. Moreover, the top of the rotor arm is made of rubber material, which is elastic and can adjust the adsorption under the action of external pressure. Even if the ceiling is uneven, the aircraft can be adjusted to be adsorbed on the ceiling, so that it can be better used in the fields of reconnaissance and eavesdropping.

DETAILED DESCRIPTION

[0015] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments:

[0016] A suction-type variant rotorcraft comprises: a fuselage 1, a rotor arm shaft 2, a rotor arm 3, a rotor 4, a rotor arm lower cover 5, and a rotor arm lower cover shaft 6; a plurality of rotor arms 3 are evenly mounted on the edge of an upper plane of the fuselage 1 through the rotor arm shaft 2, the rotor 4 is mounted inside the rotor arm 3, and a plurality of rotor arm lower covers 5 are evenly mounted on the edge of the bottom of the rotor arm 3 through the rotor arm lower cover shaft 6.

[0017] In the above structure, there are four rotor arms 3; each rotor arm 3 has four rotor arm lower covers 5; the material of the rotor arm 3 is carbon fiber; the top material of the rotor arm 3 is rubber; a camera 9 is installed on the lower surface of the fuselage 1, and several camera covers 7 are evenly installed on the edge of the lower surface of the fuselage 1 through the camera cover rotating shaft 10; there are four camera covers 7.

[0018] The rotorcraft has a transport state, a flight state, and an eavesdropping state, which respectively correspond to the functions of storage and transportation, take-off and landing flight, and reconnaissance and eavesdropping. The positions of the components of each state of the aircraft and the movement of the components when each state is transformed will be described in detail below:

[0019] Transport state: Figure 3 As shown, the aircraft occupies the least space when in transport state, and is suitable for transportation and storage; the four rotor arms 3 are all above the upper plane 8 of the fuselage, all the rotor lower covers 5 are in a closed state, all the rotors 4 are stationary, and the four camera covers 7 are all in a closed state.

[0020] Flight state: When the aircraft is in flight state, it can start flying; Figure 4 As shown, when the aircraft changes from the transport state to the flight state, the four pairs of rotors 4 begin to rotate, and at the same time the four rotor arms 3 rotate 135° around their respective rotor arm shafts 2, and then the four rotor arm lower covers 5 under each rotor arm 3 rotate downward 90° around the rotor arm lower cover shaft 6 to allow air to pass through the rotor arms 3.

[0021] Eavesdropping state: The aircraft can start eavesdropping when it is in eavesdropping state; Figure 5 As shown, when the aircraft changes from the flying state to the eavesdropping state, the upper plane 11 of the rotor arm is close to the ceiling. At this time, the rotor arm 3 is equivalent to a vacuum pump, which extracts the air above the rotor 4. At the same time, the four rotor arm lower covers 5 under each rotor arm 3 rotate upward 90° around the rotor arm lower cover shaft 6. When the rotor arm lower cover 5 is completely closed, the rotor 4 stops rotating. Because the air in the rotor arm 3 is thinner than the outside air at this time, the pressure difference between the arm and the atmospheric pressure will suck the aircraft to the ceiling. After that, the camera cover 7 rotates 90° around the camera cover shaft 10, the camera 9 starts working, and the eavesdropping work begins.

[0022] The above description is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
