Referring to FIGS. 1 to 5, a multipurpose glide flying drone assembly 10 according to an embodiment of the present invention includes a glide flying drone 200 and a glide flying drone dropping device 100. The gliding flying drone 200 includes a warhead part 210 and a fin part 230 and a body part 220 positioned between the warhead part 210 and the fin part 230.

The fin unit 230 may be located with a control wing 235 built in therein, and may have a control wing hole 230h for deployment of the control wing 235. The control blades 235 may be connected to a driving member for driving them, such as a gearbox, or an angle adjusting member capable of adjusting the angle of the control blades 235 with respect to the flight direction, and may be located in the fin.

The body portion 220 has a glide wing 225 is built into the inside, and may be provided with glide wing holes (220h) for the deployment of the glide wing 225 on both sides. For example, the gliding blade 225 may be provided in a manner that slides 90 degrees around a rotational axis coupled to one end of the gliding blade, or a two-stage or three-stage wing member is combined and protruded to the outside. I can. In addition, it is preferable that the glide wing 225 is located in the center of gravity of the glide flying drone 200 in order to optimize glide flight.

The glide flying drone 200 may include a GPS sensor and a flight control module for location tracking and location detection, and may include a camera module for surveillance and reconnaissance as well as having a precision bomb or leaflet or transport material. Furthermore, the gliding flying drone 200 may be equipped with a parachute, and landing using a parachute at a flight target point is possible, so that a separate large-scale landing space is not required, and thus materials can be efficiently transported.

The gliding drone dropping device 100 is located in the hangar of the transport aircraft, but opens and closes a plurality of cylindrical storage members 110 in which the gliding flying drones 200 are respectively accommodated and an opening formed at one side of the storage member 110 It may include an opening and closing member 120. Accordingly, a plurality of gliding flying drones can be safely accommodated and transported in the transport aircraft to the dropping point due to the gliding flying drone dropping device 100.

The gliding flying drone dropping device 100 may have a predetermined tilting angle θ so that the warhead 210 of the gliding flying drone 200 is upward at the drop point, and the opening/closing member 120 is driven. Thus, the opening of the storage member 110 may be opened so that the gliding flying drone 100 may be discharged to the outside of the hangar. At this time, the gliding flying drone dropping device 200 may include an angle adjusting member 130 at the lower part that provides a tilting angle θ at the drop point. In addition, as another example, the hangar of the transport aircraft may be provided with a dropping device fixing member for fixing the gliding flying drone dropping device 100 or providing the tilting angle θ.

In other words, when one side of the glide flying drone dropping device 100 moves in the upward direction (A) so that the warhead part 210 is upward, the glide flying drone 200 is moved at the resulting tilting angle θ. Gravity is received in the direction, and the glide-flying drone 200 can be dropped to the outside of the transport plane without external power only by opening the opening.

Further, the gliding flying drone dropping device 100 may include a position fixing device that prevents the protrusion of the control blade 235 or the gliding blade 225 before dropping on the inner surface of the storage member 110, For example, a position fixing device may be located on the inner surface of the receiving member 110 corresponding to the position of the control blade groove 230h or the glide blade groove 220h. The position fixing device may be released from the gliding flying drone 200 upon arrival at the dropping point.

The gliding flying drone 100 may be received so that the opening/closing member 120 and the fin unit 230 are in contact with each other, and thus may be discharged from the fin unit 230 to the outside of the hangar.

In addition, after the gliding flying drone 100 is discharged from the hangar, the control wing 235 may be first deployed before the gliding wing 225 is deployed. Therefore, the control wing 235 may be first deployed, thereby aligning the initial flight posture, and thereby, the glide flying drone 100 may have a flight posture like an arrow. In addition, drag may be increased by the control wing 235 and thus the distance from the transport plane may be increased. This also has the effect of securing time and space to protect friendly transport aircraft when the glide-flying drone 100 is equipped with a precision bomb.

The gliding flying drone 200 initially free-falls at a predetermined altitude at the dropping point as shown in 2 of FIG. 2, but may be individually controlled so that the altitudes of the free-fall are different from each other. The gliding flying drone 200 can freely fall to obtain the energy required for flight, and since it is individually controlled so that the altitude is different from each other, it will fly with different energies even if it is dropped from the same dropping point at one time and reach a plurality of target points, respectively. The glide flying drone 200 can reach. Therefore, the gliding flying drone 200 may perform a dropping bomb or material transport through gliding flight without a separate thrust according to the dropping time and the fall altitude. For example, due to the deployment and individual control of the control wing and the gliding wing, long-distance transport (L) or long-distance strike such as target point T1 as shown in FIG. 1 can be performed, and bypass transport (D) as target point T2. Alternatively, you can perform a bypass strike.

Therefore, it has the advantage of being able to carry out dropping bombs or material transport through glide flight without additional thrust, and because it is a non-powered flight, glide flight, it can penetrate into enemy territory through long-distance flight without noise. Supplies can be delivered quickly and accurately, and since long-distance dropping is possible, the survivability of transport aircraft from enemy air defense systems can be improved.

The gliding flying drone dropping device 100 includes the cylindrical storage member 110 in a matrix, and the opening and closing member 120 is sequentially driven from one row to open the opening of the storage member 110. have. Therefore, even if a plurality of glide flying drones 200 are thrown, they do not affect each other's glide flight, and each glide flying drone can accurately reach the target point targeted by the glide flying drone.

Therefore, it is possible to save time and cost by simultaneously transporting from a transport ship or a transport helicopter to multiple targets without restriction by the terrain, and to reduce the interval between the sorting missions of the transport aircraft. In addition, the glide-flying drone assembly 10 may be capable of developing various derivative models such as long-distance precision bomb dropping, leaflet spraying, surveillance and reconnaissance, depending on the purpose.

In the driving method of the multi-purpose glide-flying drone assembly 10 according to the embodiment of the present invention, the multi-purpose glide-flying drone assembly 10 is accommodated in a hangar of a transport aircraft and transported to a dropping point, and the hangar is opened at the dropping point. , Providing a tilting angle (θ) to the gliding flying drone dropping device 100, the opening of the receiving member 110 is opened by driving the opening and closing member 120 of the gliding flying drone dropping device 100 And discharging the gliding flying drone 200 from the storage member 1110 to the outside of the hangar.

When described in detail with reference to FIGS. 1 to 6, the driving method of the multipurpose glide flying drone assembly 10 according to the embodiment of the present invention includes a glide flying drone 200 and a glide flying drone dropping device 100. The multi-purpose glide-flying drone assembly 10 may be accommodated in a hangar of a transport aircraft and transported to the dropping point (S110).

Next, when the transport plane arrives at the dropping point, control of the glide flying drone dropping device 100 can be started (S120). For example, a tilting angle θ may be provided to the glide flying drone dropping device 100. One side of the glide flying drone dropping device 100 is moved upward so that the warhead 210 of the glide flying drone 200 is upwardly provided by the angle adjusting member 130 provided under the glide flying drone dropping device 100. By moving in the direction (A), the tilting angle (θ) can be given, and the tilting angle (θ) is given to the gliding flying drone dropping device 100 through a dropping device fixing member provided in the hangar of the transport aircraft. Can be.

In addition, the storage member 110 of the gliding flying drone dropping device 100 can be opened (S130). That is, when the opening and closing member 120 provided in the opening of the storage member 110 operates to open the opening, the gliding flying drone 100 located in the storage member 110 may be discharged to the outside of the hangar. That is, since one side of the glide flying drone dropping device 100 moves in the upward direction (A) so that the warhead 210 is upward, the glide flying drone 200 receives gravity in the direction of the fin With only opening, the gliding flying drone 200 can be dropped to the outside of the transport aircraft without external power.

Next, as shown in 1 of FIG. 2, the glide flying drone 200 may be discharged to the outside of the transport plane (S140). At this time, the receiving member 110 in which the position fixing tool is located corresponding to the position of the control wing groove 230h or the gliding wing groove 220h, when the opening is opened after arriving at the dropping point, the glide flying drone 200 Can be released from ). In addition, the gliding flying drone dropping device 100 includes the cylindrical storage member 110 in a matrix, and the opening and closing member 120 is sequentially driven from one row to open the opening of the storage member 110. have. For this reason, even if a plurality of glide drones 200 are thrown, they do not affect each other's glide flight, and each glide flying drone can accurately reach the target point targeted by the glide flying drone.

Next, as shown in 2 of FIG. 2, the gliding flying drone 200 discharged to the outside of the hangar may freely fall at a predetermined altitude (S150). At this time, the gliding flying drone 200 may further secure a flight speed with energy due to a predetermined free fall along with the speed of the initial transport plane, and further, may be individually controlled so that the altitudes of the free fall are different from each other. That is, each of the glide flying drones 200 may individually control the glide flight distance of the glide flying drone 200 by controlling the flight speed by individually controlling the free fall altitude. Therefore, by individually controlling the altitude at which the glide flight starts to be different from each other, even if it is released from the same dropping point, it is possible to glide and fly with different energies, and each glide flying drone 200 can reach a plurality of target points. . Therefore, the gliding flying drone 200 may perform a dropping bomb or material transport through gliding flight without a separate thrust according to the dropping time and the fall altitude. For example, it is possible to perform long-distance transport (L) or long-distance strike such as target point T1 as shown in FIG. 1 by controlling the deployment of the control wing and glide wing, and bypass transport (D) or bypass strike as shown in the target point T2. You can do it.

Next, after securing the flight speed due to the initial free fall, it is possible to control the posture by deploying the control wing 235 as shown in 3 of FIG. 2 (S160). At this time, it is possible to perform initial posture alignment by grasping the current position by the flight control module and GPS installed inside. For example, a glide-flying drone can be upside down or rotate continuously, but by deploying the control wing and adjusting the angle of the control wing, it receives air resistance, so that the posture of the glide-flying drone can be properly positioned. Therefore, the control wing 235 is deployed first, and after the initial posture alignment, the gliding flying drone 100 has a flight posture like an arrow, and the drag is increased by the control wing 235 so that the distance from the transport plane can be increased. . This also has the effect of securing time and space to protect friendly transport aircraft when the glide-flying drone 100 is equipped with a precision bomb.

Next, the gliding flying drone 200 released to the outside of the hangar through the above process analyzes the current position and flight direction of each of the gliding flying drones 200 after aligning the initial posture to detect the altitude, and Likewise, the gliding wings are deployed so that the gliding flight can be performed to the target point (S170). For example, the gliding blade 225 may be rotated 90 degrees in a sliding manner, or may be provided in a manner in which a wing member of two or three stages is combined and protruded to the outside. As a process of guiding the path when the altitude is detected, analyzing the flight line between the current position of each glide flying drone 100 and the path point, and controlling the wing angle or the direction of the wing of the control wing and the glide wing to maintain the flight path. You can control glide flight. And, as a process of following the route point, it is possible to control the flight for guided flight to the route point or the target point.

In addition, the gliding flying drone 200 is equipped with a parachute so that it can deploy a parachute in a section near the target point as shown in Fig. 2, and because a separate large-scale landing space is not required for landing using this, it efficiently transports materials. can do. For example, it is possible to enter the angle of fall (AOF) near the target point as shown in Fig. 2, and hit the target point through vertical fall, expand the range of destruction, or adjust the range of goods transport, deploy the parachute. And so on.

Therefore, in FIG. 2, 1 is an initial fall through discharge from a transport plane, 2 is a free fall to secure the speed of a glide flying drone, and 3 to 4 are glides for initial posture alignment, path guidance and path point tracking. For example, flight, 5 is the rush section of the drop mode.

Next, the gliding flying drone may reach the target point (S180). For example, it is possible to perform long-distance transport (L) or long-distance strike such as target point T1 as shown in FIG. 1 by controlling the deployment of the control wing and glide wing, and bypass transport (D) or bypass strike as shown in the target point T2. You can do it. In addition, it is possible to reach a plurality of target points as targets according to the controlled flight altitude for each glide flying drone. Therefore, it has the advantage of being able to carry out dropping bombs or material transport through glide flight without additional thrust, and because it is a non-powered flight, glide flight, it can penetrate into enemy territory through long-distance flight without noise. Since materials can be quickly and accurately delivered and long-distance dropping is possible, the survivability of transport aircraft from the enemy's anti-aircraft defense system is improved, and various derivative models such as long-range precision bomb dropping, leaflet spraying, and surveillance and reconnaissance can be developed. Furthermore, it is possible to save time and cost by simultaneously transporting from a transport ship or a transport helicopter to multiple targets without being restricted by the terrain, and to shorten the interval between transport aircraft sorting missions.

Although the above has been described with reference to preferred embodiments of the present invention, those skilled in the art will variously modify and change the present invention within the scope not departing from the spirit and scope of the present invention described in the following claims. You will understand that you can do it.
