Description

reconnaissance drone The present invention relates to a reconnaissance drone for reducing the probability of detection by an enemy. The importance of reconnaissance drones is increasing due to recent conflicts such as the war in Ukraine and the Israeli-Hamas dispute. While most existing reconnaissance drones are of the fixed-wing or rotary-wing type, it is necessary to plan for the development of reliable tactical equipment that reduces the probability of detection by the enemy during low-altitude flights, taking into account the mountainous terrain of Korea in particular. FIG. 1 is an explanatory diagram of the reconnaissance drone and controller of the present invention. FIG. 2 is a top-view center perspective view of a reconnaissance drone with its wings removed according to the present invention. FIG. 3 is a frontal perspective view of the reconnaissance drone of the present invention. FIG. 4 is an explanatory diagram of the link unit of the present invention. FIG. 5 is a perspective view of the body unit and tail unit of the present invention. Fig. 6 is a front view of Fig. 5. Using FIGS. 1 to 6, the reconnaissance drone (10) of the present invention will be described. The first direction (x-axis direction) axis can correspond to the rolling axis among the aircraft's rotation axes, the second direction (y-axis direction) axis can correspond to the pitching axis, and the third axis (z-axis direction) axis, which is the vertical axis, can correspond to the yawing axis. Referring to FIGS. 1, FIGS. 2, and FIGS. 5, the overall structure of the reconnaissance drone (10) will be explained. FIG. 1 is a real photograph of a reconnaissance drone (10) with a portion removed and a controller (50) controlling the drone (10), FIG. 2 shows the state in which the components (e.g., control unit (120) or wing motor (130)) or wings (310) of the receiving space (112) in FIG. 1 are removed, and FIG. 5 may show the state in which the wings (310) or link unit (400) are removed. The reconnaissance drone (10) may include at least one of a body unit (100), a tail unit (200), a wing unit (300), and a link unit (400). The control unit (120), wing motor (130), or tail motor (230) related to the flight operation of the drone (10) may be controlled or commanded by the controller (50). The controller (50) may include a terminal such as a mobile phone or a PC. The controller (50) communicates wirelessly with the control unit (120) and can issue commands/instructions to the control unit (120), the wing motor (130) may receive control signals from the control unit (120), and the tail motor (230) may receive control signals from the control unit (120) or directly from the controller (50). As a result, the drone user can freely operate the wings (310) or the tail (210) through an interface such as a UI of the controller (50). The body unit (100) may include at least one of a body part (110) which serves as the central frame of the drone (10), a receiving space (112) formed inside the body part (110), a control unit (120) which controls the overall operation of the drone (10), a wing motor (130) which drives a link unit (400) so that the wing (310) can move up and down, a gear (150) which receives driving force from the wing motor (130) and transmits it to the link unit (400), a gear hole (170), and a sensor hole (190). The control unit (120) or the wing motor (130) may be housed or embedded in the receiving space (112). The gear hole (170) or sensor hole (190) may be located on the front of the drone (10), body unit (100), or body part (110). The shaft or axis of the gear (150) can pass through the gear hole (170). The shaft or axis of the gear (150) passing through the gear hole (170) can be connected to the shaft or axis of the wing motor (130) of the receiving space (112) through a coupler (not shown), etc. In the drawing, the body part (110) and the link unit (400) are exposed to the outside, but the final finished product of the drone (10) may have a head part (not shown) corresponding to a bird's head in the front direction of the body part (110) or the body unit (100). The head part may be equipped with various sensors for monitoring the surroundings or collecting information, and power lines may be required to operate the sensors or the head part as needed. In this way, a sensor connection line connecting the sensor of the head part to the control unit (120) housed in the body part (110) or the housing space (112), and a power line for driving the head part may pass through the sensor hole (170). The tail unit (200) may include a tail (210) that changes the direction of the drone (10), or a tail motor (230) that drives the tail (210). The tail motor (230) may receive a command for a rudder amount from the control unit (120) or the controller (50). The rudder amount varies depending on the rotation angle of the tail (210), and the degree of direction change may be determined. The rudder amount may be related to direction change or
