The body 100 may be, for example, a body of a drone.

Specifically, the body 100 includes an upper frame 110 on which the thrust generating unit 200 and the flight control unit 300 are mounted, a lower frame 110 connected to the lower surface of the upper frame 110, And a landing support 130 connected to the upper frame 110 and the lower frame 120 to contact the ground when the body 100 is landed.

2, the upper frame 110 is provided with a first hollow section 112 for mounting the first thrust generating member 210 and a second hollow section for mounting the second thrust generating member 220, A compartment 114 may be provided and a closed compartment 116 may be provided between the first cavity 112 and the second cavity 114.

The first cavity section 112 and the second cavity section 114 may be spaced apart from each other in the longitudinal direction or the first direction of the upper frame 110. In the first cavity section 112, The thrust generating member 210 may be mounted and the second thrust generating member 220 may be mounted at the center point of the second hollow section 114. [

The upper frame 110 is provided with a first arm 1122 and a second arm 1122 extending along the second direction or in a direction perpendicular to the longitudinal direction of the upper frame 110 on the same line as the center point of the first cavity 112, An arm 1124 may be provided.

Likewise, the upper frame 110 is provided with a third arm 1142 and a fourth arm 1142 extending in a direction perpendicular to the longitudinal direction of the upper frame 110 or in a second direction on the same line as the center point of the second cavity section 114, An arm 1144 may be provided.

The first arm 1122 and the second arm 1124 may be disposed to face each other with respect to the first cavity section 112 and the first flight control member 310 And a second flight control member 320 may be mounted on the end of the second arm 1124. [

The third arm 1142 and the fourth arm 1144 may be arranged to face each other about the second hollow section 114 and the third flight control member 330 may be disposed at the end of the third arm 1142. [ And a fourth flight control member 340 may be mounted on the end of the fourth arm 1144. [

However, the shape of the body 100 is not limited to this, and may vary depending on the configurations and arrangements of the thrust generating unit 200, the flight control unit 300, the power unit 400, and the power transmission unit 500 Of course.

As described above, the upper frame 110 may be equipped with a thrust generating unit 200 for taking off or leveling the body 100.

The thrust generating unit 200 may be provided in the form of a large propeller, for example, and may include a plurality of thrust generating members.

Hereinafter, a case where a plurality of thrust generating members include a first thrust generating member 210 and a second thrust generating member 220 will be described as an example.

The first thrust generating member 210 and the second thrust generating member 220 may be driven by the power unit 300. The first thrust generating member 210 and the second thrust generating member 220 may be driven by the power unit 300, .

For example, the body 100 can be taken off by rotating the first thrust generating member 210 and the second thrust generating member 220 at a high speed, and the first thrust generating member 210 and the second thrust generating member 220 are rotated at a constant speed to fly the body 100 at a constant height (or horizontal flight).

The first thrust generating member 210 and the second thrust generating member 220 may be rotated in the same direction or in different directions by the power transmitting unit 400.

For example, when the first thrust generating member 210 rotates clockwise, the second thrust generating member 220 may rotate clockwise or counterclockwise. Or when the first thrust generating member 210 rotates counterclockwise, the second thrust generating member 220 may rotate in a counterclockwise or clockwise direction. Accordingly, the first thrust generating member 210 and the second thrust generating member 220 are rotatable in any direction.

However, when the first thrust generating member 210 and the second thrust generating member 220 are rotated in the same direction, the rotational moment of the body 100 may be canceled to prevent the body 100 from rotating during the flight When the first thrust generating member 210 and the second thrust generating member 220 rotate in opposite directions to each other, the rotational moment of the body 100 is canceled, and the rotation of the body 100 during the flight It can be automatically prevented.

The driving of the first thrust generating member 210 and the second thrust generating member 220 will be described in detail below.

In addition, the upper frame 110 may further include a flight control unit 300 for controlling the posture of the body 100 or the direction of the flight.

The flight control unit 300 may be provided in the form of a small propeller, for example, and may include a plurality of flight control members.

Hereinafter, a case where a plurality of flight control members include a first flight control member 310, a second flight control member 320, a third flight control member 330, and a fourth flight control member 340 will be described as an example I will explain.

At this time, the first flight control member 310 and the second flight control member 320 may be disposed to face each other with respect to the first cavity section 112, and the third flight control member 330 and the fourth flight control member 320 The control member 340 may be disposed to face each other about the second cavity section 114. [

Also, considering the momentum conservation, for example, when the first flight control member 310 rotates clockwise, the second flight control member 320 and the third flight control member 330 rotate in the counterclockwise direction , And the fourth flight control member 340 can rotate clockwise.

When the first flight control member 310 rotates counterclockwise, the second flight control member 320 and the third flight control member 330 rotate clockwise and the fourth flight control member 340 rotates clockwise, Can be rotated counterclockwise.

On the other hand, the rotational direction or rotational speed of the first flight control member 310, the second flight control member 320, the third flight control member 330, and the fourth flight control member 340 can be controlled individually , Whereby the posture or flight direction of the body 100 can be controlled.

The thrust generating unit 200 and the flight control unit 300 described above may be driven by the power unit 400.

The power unit 400 may include a plurality of power sources.

For example, the plurality of power sources may include an engine 410 and a motor 420.

The engine 410 is for driving the thrust generating unit 200 and may be disposed in the lower frame 120 of the body 100.

In this case, the engine 410 may be a small engine, and a fuel tank 412 in which liquid fuel (for example, airplane fuel, gasoline, etc.) is stored in the engine 410 is stored in the lower frame 120 .

In addition, the rotation axis of the engine 410 may extend from the lower frame 120 to protrude to the outside so as to penetrate the upper frame 110. The driving force from the engine 410 can be transmitted to the thrust generating unit 200 by arranging the rotation axis of the engine 410.

The motor 420 is for driving the flight control unit 300 and includes a first arm 1122, a second arm 1124, a third arm 1142 and a fourth arm 1144 of the upper frame 110 Respectively.

At this time, the motor 420 may be provided by, for example, a DC motor, and a first flight control member 310, a second flight control member 320, a third flight control member 330 And a fourth flight control member 340 may be connected.

For example, when the first motor 422 is mounted on the first first flight control member 310, the second motor 424 is mounted on the second flight control member 320, and the third motor 426, And the fourth motor 428 may be mounted on the fourth flight control member 340. The fourth flight control member 340 may be mounted on the third flight control member 330,

The driving force from the motor 420 can be directly transmitted to the flight control unit 300 by the arrangement of the motor 420 and the first flight control member 310, the second flight control member 320, The control member 330 and the fourth flight control member 340 may be individually rotated or controlled.

In addition, the motor 420 can receive power from the battery 430, for example, a secondary battery disposed in the lower frame 120, for example. However, the manner of power supply of the motor 420 is not limited to this, and any of them can operate the motor 420.

As described above, the power unit 400 includes a plurality of power sources, and the thrust generator 200 and the flight controller 300 can be driven by different power sources.

For example, when the body 100 takes off from the ground, the thrust generating unit 200 and the flight control unit 300 can be driven by the engine 410 and the motor 420, and the body 100 can be driven from the ground The flight control unit 300 can be driven by the motor 420 when the posture of the body 100 or the flight direction is required to be controlled after taking off. When the body 100 makes horizontal flight in the air, the thrust generating unit 200 can be driven by the engine 410.

In this case, by using different power sources, for example, the power of the battery 430 that supplies power to the motor 420 can be minimized or the use of the fuel used in the engine 410 can be reduced , The flying time of the body (100) or the body time can be increased.

Meanwhile, the power transmission unit 500 may be disposed on the body 100 to transmit the power from the power unit 400, particularly the engine 410, to the thrust generating unit 200.

4, the power transmitting portion 500 may include a power transmitting member 510, and the power transmitting member 510 may transmit power generated from the engine 410 to the first thrust generating member 210 And the second thrust generating member 220 to rotate the first thrust generating member 210 and the second thrust generating member 220 in the same direction.

For example, the power transmitting member 510 may be provided with a plurality of belts.

The belt may be provided with a timing belt or a poly-V (V) belt.

The timing belt is a belt having grooves with an equal interval on the inside so as to accurately engage grooves of belt pulleys having equally spaced grooves as gears, so that the rotation of the parts can be more accurately transmitted.

In addition, the poly V (V) belt has a flexible cross-sectional shape of a V-shaped cross-sectioned belt with no joints, and is made by pressurizing synthetic rubber with pores.

However, the type of the belt is not limited thereto, and any type of belt can be used as long as it can transmit driving force or rotational force from the power source 400 to the thrust generating unit 200.

One of the plurality of belts may transmit the power generated from the engine 410 to the first thrust generating member 210 and the other of the plurality of belts may be generated from the engine 410 And transmits the generated power to the second thrust generating member 220.

A belt pulley may be provided on the rotation axis of the engine 420, the rotation axis of the first thrust generating member 210, and the rotation axis of the second thrust generating member 220 for mounting the belt described above.

The belt pulley is a wheel attached to a shaft for the purpose of engaging the belt when the belt is driven, wherein one of the plurality of belts spans the first belt pulley 5122 and the second belt pulley 5124, May pass over the first belt pulley 5122 and the third belt pulley 5126.

A plurality of belts may be arranged in a multi-stage configuration on the belt pulley provided on the rotary shaft of the engine 420 so that the first thrust generating member 210 is disposed above the second thrust generating member 220 .

Referring again to FIG. 1, the power transmitting member 510 may further include a plurality of idlers 512.

The plurality of idlers 512 may be disposed in contact with the plurality of belts on the closed section 116 of the upper frame 110. For example, a plurality of idlers 512 may contact a surface of the belt that is not in contact with the belt pulley.

At this time, the plurality of idlers 512 may play a role of keeping the tension of the plurality of belts constant.

The first thrust generating member 210 and the second thrust generating member 220 can be rotated as follows by the configuration of the first power transmitting portion 510. [

For example, when the rotational axis of the engine 420 rotates in a clockwise direction, one of the plurality of belts may rotate according to the rotational direction and rotational speed of the rotational axis of the engine 420, The rotating shaft of the generating member 210 can also rotate at the rotating direction and at the rotating speed of the rotating shaft of the engine 420. [

On the other hand, when the rotational axis of the engine 420 rotates in the clockwise direction, the other one of the plurality of belts can rotate according to the rotational direction and rotational speed of the rotational axis of the engine 420, The rotational axis of the member 220 can also rotate at the rotational direction and rotational speed of the rotational axis of the engine 420. [

The power from the engine 420 can be simultaneously transmitted to the first thrust generating member 210 and the second thrust generating member 220 by the power transmitting member 510 at the same time. In other words, the rotational axis of the engine 420, the rotational axis of the first thrust generating member 210, and the rotational direction and rotational speed of the rotational axis of the second thrust generating member 220 may all be the same.

Further, by using a belt such as a timing belt or a poly-V belt, the rotational speeds of the first thrust generating member 210 and the second thrust generating member 220 can be kept the same.

When the first thrust generating member 210 and the second thrust generating member 220 are rotated in the same direction, the first thrust generating member 210 and the second thrust generating member 220 rotate to rotate the body 100, A rotational moment may be generated in the body 100 and the body 100 may rotate. In this case, rotation of the first to fourth flight control members 310, 320, 330, and 340 of the flight control unit 300 can be separately controlled to prevent rotation of the body 100.

5, the power transmitting portion 500 may include a first power transmitting member 520 and a second power transmitting member 530. [

At this time, the first power transmitting member 520 transmits the power generated from the engine 410 to the second thrust generating member 220, and the second power transmitting member 530 transmits the power generated from the engine 410 1 th force generating member 210 as shown in Fig.

The first power transmitting member 520 receives power from the rotational axis of the engine 410 and rotates about the first rotational axis X1 to rotate one of the plurality of thrust generating members such as the second thrust generating member 220 And the second power transmitting member 530 rotates about the second rotation axis X2 disposed apart from the first rotation axis X1 to rotate the other one of the plurality of thrust generating members, The first thrust generating member 210 can be rotated.

For example, the first power transmitting member 520 includes a first belt 522 connected to the rotation axis of the engine 410 and the first rotation axis X1, a first rotation axis X1 and a second thrust generating member 220, And a second belt 524 connected to the rotational axis of the second belt 524.

The first rotating shaft X1 and the second thrust generating member 220 may be provided with belt pulleys for supporting the first belt 522 on the rotating shaft of the engine 410 and the first rotating shaft X1, And a belt pulley for supporting the second belt 524 may be provided on the rotation shaft of the second belt 524, respectively. At this time, a plurality of belt pulleys may be spaced apart from each other along the longitudinal direction of the first rotation axis X1 on the first rotation axis X1.

The second power transmitting member 530 may include a third belt 532 connected to the second rotation axis X2 and the rotation axis of the first thrust generating member 210. [ At this time, a belt pulley for supporting the third belt 532 may be provided on the rotation axis of the second rotation axis X2 and the first thrust generating member 210, respectively.

Thus, the second power transmitting member 530 may not directly transmit the power generated from the engine 410 to the first thrust generating member 210.

The first power transmitting member 520 and the second power transmitting member 530 are respectively provided with a first gear 526 and a second gear 526 for transmitting the power generated from the engine 410 to the first thrust generating member 210. [ A second gear 534 may be provided.

The first gear 526 may be disposed on the first rotation axis X1 between the first belt 522 and the second belt 524 and the second gear 534 may be disposed on the second rotation axis X2 1 gear 526, as shown in Fig. It is to be understood that the first gear 526 and the second gear 534 may have different gear ratios or the same gear ratios.

The second gear 534 may transmit the power generated from the engine 410 to the first thrust generating member 210 by engagement with the first gear 526. Therefore, the first thrust generating member 210 can indirectly receive the power generated from the engine 410.

The first and second power transmission members 520 and 530 are provided with gears 526 and 534 that rotate in mesh with each other so that the first thrust generating member 210 and the second thrust generating member 220 Can rotate in different directions.

Specifically, the first thrust generating member 210 and the second thrust generating member 220 can be rotated by the engine 410 next.

When the rotation axis of the engine 410 rotates clockwise, the first belt 522, the first gear 526, and the second belt 524 can rotate clockwise. At this time, the second gear 534 and the third belt 532 can be rotated counterclockwise by the clockwise rotation of the first gear 526.

The second thrust generating member 220 associated with the second belt 524 rotates in a clockwise direction while the first thrust generating member 210 associated with the third belt 532 can rotate in a counterclockwise direction .

On the other hand, when the rotation axis of the engine 410 rotates counterclockwise, the first belt 522, the first gear 526, and the second belt 524 can rotate in the counterclockwise direction. At this time, the second gear 534 and the third belt 532 can be rotated clockwise by the counterclockwise rotation of the first gear 526.

The second thrust generating member 220 associated with the second belt 524 rotates counterclockwise while the first thrust generating member 210 associated with the third belt 532 can rotate clockwise .

When the first thrust generating member 210 and the second thrust generating member 220 are rotated in different directions as described above, the momentum conservation law is satisfied, and the rotation of the body 100 during flight can be automatically prevented .

Further, by using a belt such as a timing belt or a poly-V belt, the rotational speeds of the first thrust generating member 210 and the second thrust generating member 220 can be kept the same.

As described above, in the air vehicle 10 according to the embodiment, the power transmitting portion 500 transmits the power from the engine 410 to the thrust generating portion 200 using a belt and a belt pulley, for example, The configuration of the power transmitting portion 500 is not limited to this, and any configuration is possible as long as the power from the engine can be efficiently transmitted to the thrust generating portion 200.

Although it has been described that the power from the engine 410 is directly transmitted to the second thrust generating member 220 and indirectly transmitted to the first thrust generating member 210 by the gear engagement structure, 410 may be directly transmitted to the first thrust generating member 210 and indirectly transmitted to the second thrust generating member 220 by the gear engagement structure.

In addition, the air vehicle 10 may further include a control unit 600 disposed at a lower end of the lower frame 120 according to an embodiment of the present invention.

The control unit 600 includes a wireless communication device for controlling the attitude of the body 100 and transmitting and receiving signals wirelessly, an electronic transmission (or electronic speed control board) for controlling the speed of the motor 420, a power controller, (FC), or a video transmitter for capturing and transmitting images to and from a camera.

However, it is needless to say that the configuration of the control unit 600 is not limited to this, and additional configurations may be added to suit the intended use of the air vehicle 10 according to the embodiment.

As described above, in the airplane according to the embodiment, the thrust generating unit and the flight control unit are driven by different power sources to extend the flight time of the airplane, and the flight control unit controls the posture of the body or the direction of the airplane, You can induce a flight. Further, by using a small-sized engine as a power source, it becomes lighter, and a simple structure can be provided to facilitate maintenance.
