First Embodiment
Hereinafter, an aircraft according to a first embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1 and FIG. 2, the flying object according to the present embodiment can be advanced in the forward direction D1 (first direction: + Y direction), and backward direction D2 (second direction: -Y direction) Go backwards. In addition, it can rise in the upward direction (third direction: + Z direction), and can descend in the ↓ direction (−Z direction).

  As shown in detail in FIG. 2, the airframe is a combination of the airframe 10 and the appendage 20. Note that other elements may be included as necessary.

  The airframe unit 10 includes a main body unit 13 and a lift generating unit (described later). The main body 13 has a U-like shape. The lift generation unit includes an arm 12 extending from the main body 13, a motor 14 attached to each end of the arm, and propellers 11a to 11d attached to the motor 14, respectively.

  As well shown in FIG. 2, the main body 13 according to the present embodiment has a substantially U shape when viewed from the Z direction. That is, it has a right side portion 13R and a left side portion 13L extending along the Y direction, and a connecting portion 13C connecting the rear ends (ends in the -Y direction) of the right side portion 13R and the left side portion 13L.

  With such a configuration, in the main body portion 13, an enclosed space E surrounded by the right side portion 13R, the left side portion 13L, and the connecting portion 13L is present. In the present embodiment, since the connecting portion 13C is located at the rear end of each of the right side portion 13R and the left side portion 13L, the U-shape of the main body portion has a direction opened forward.

  The main body portion 13 may have, for example, a substantially C-like shape or a substantially U-like shape as long as it has a shape having an open front direction (details will be described later) ).

  The attachment portion 20 according to the present embodiment has a mounting portion 21 and a rod-like frame 22. The mounting portion 21 is fixed near the center of the frame 22.

  The mounting portion 21 has a shape that at least partially fits in the enclosed space E. As well shown in FIG. 1, the mounting portion 21 is mounted at least on the inner side (side surface on the enclosed space side: mounting side surface) of the right side portion 13R and the left side portion 13L. Various techniques can be applied as the method of attachment.

  A camera 23 is provided at the tip of the frame 22, and it is possible to capture the front. The type of camera is not particularly limited, and may be appropriately selected depending on the purpose and application. Also, if necessary, gimbals may be attached to the camera.

  As shown in FIGS. 5 and 6, the aircraft is in a state in which the airframe portion 10 and the appendage 20 are kept horizontal at the time of hovering (FIGS. 5 and 6).

  Also, as shown in FIG. 7, the attachment 20 contacts the ground at takeoff and landing. The legs may be attached separately.

  Furthermore, as shown in FIG. 8, when advancing, by raising the output of the propeller on the rear side, it is in the forward leaning posture.

Second Embodiment
As shown in FIGS. 9 and 10, the flying object according to the second embodiment of the present invention differs from the attachment 20 according to the first embodiment described above in the structure of the attachment 20 '. The other structure is the same as that of the aircraft according to the first embodiment. In the following description, the same elements will be denoted by the same reference symbols, and the description thereof will be omitted.

  As shown in FIG. 9, the attachment 20 ′ according to the present embodiment is connected to the main body 13 by the rotation shaft 30. With such a structure, the appendage 20 'can be rotated in a predetermined range around the rotation axis 30 in the YZ plane.

  As best shown in FIGS. 9 (a) and 10, the appendages are partially located within the enclosed area E.

  In particular, when viewed along the X direction, the attachment portion 20 ′ is formed with a substantially Ω-shaped relief portion 25. According to this structure, even when the long attachment 20 'is used, a collision between the attachment 20' and the main body 13 can be prevented by the relief 25 straddling the connection 13C.

  Although the flying body shown in FIGS. 9 and 10 has the relief portion 25, the relief portion 25 may not be provided when using a short appendage.

  The above-described aircraft has, for example, the functional blocks shown in FIG. The functional block in FIG. 8 is the minimum reference configuration.

  The flight controller can include one or more processors, such as a programmable processor (e.g., a central processing unit (CPU)).

  The flight controller has a memory (not shown) and can access the memory. The memory stores logic, code, and / or program instructions that can be executed by the flight controller to perform one or more steps.

  The memory may include, for example, a removable medium such as an SD card or random access memory (RAM) or an external storage device. Data obtained from cameras and sensors may be directly transmitted and stored in a memory. For example, still image / moving image data captured by a camera or the like is recorded in the built-in memory or the external memory.

The flight controller includes a control module configured to control the state of the aircraft. For example, the control module may adjust the spatial arrangement, velocity, and / or acceleration of an aircraft having six degrees of freedom (translational motion x, y and z, and rotational motion θ _x , θ _y and θ _z ) Control the propulsion mechanism (motor etc.) of the flying object. The control module can control one or more of the mounting unit and the state of the sensors.

  The flight controller can be in communication with a transceiver configured to transmit and / or receive data from one or more external devices (e.g., a terminal, a display, or other remote controller). The transceiver may use any suitable communication means, such as wired communication or wireless communication.

  For example, the transmitting and receiving unit uses one or more of a local area network (LAN), wide area network (WAN), infrared, wireless, WiFi, point-to-point (P2P) network, telecommunications network, cloud communication, etc. be able to.

  The transmission / reception unit can transmit and / or receive one or more of data acquired by sensors, processing results generated by the flight controller, predetermined control data, user commands from a terminal or a remote controller, etc. .

  The sensors according to the present embodiment may include an inertial sensor (acceleration sensor, gyro sensor), a GPS sensor, a proximity sensor (eg, a rider), or a vision / image sensor (eg, a camera).

  The aircraft of the present invention can be expected to be used as an industrial aircraft in research, surveying, observation and the like. In addition, the aircraft of the present invention can be used in the aircraft related industry such as multicopter drone, and furthermore, the present invention can be suitably used also as an aircraft for aerial photography equipped with a camera etc. Besides, it can be used in various industries such as security field, agriculture and infrastructure monitoring.

  The embodiments described above are merely examples for facilitating the understanding of the present invention, and are not intended to limit and interpret the present invention. It goes without saying that the present invention can be modified and improved without departing from the gist thereof, and that the present invention includes equivalents thereof.
