However, their limited range makes long-distance aerial delivery difficult. Furthermore, helicopters and other vertical takeoff and landing aircraft are often limited in their payload capacity and are susceptible to environmental factors such as weather. Fixed-wing aircraft, however, are unable to fly at low altitudes due to terrain and weather conditions, and high-altitude aerial deliveries pose challenges in ensuring accuracy.

DETAILED DESCRIPTION

[0021] The following is a specific implementation method with reference to the accompanying drawings.

[0022] Example

[0023] like Figure 1-6 As shown, in this embodiment, a precision-guided, air-dropped, gliding, and slow-descent transport drone is primarily disclosed. The drone comprises a box body 1, which can accommodate and connect a glider 2. A parachute compartment 3 and a cargo hold 4 are disposed below the box body 1. The cargo hold 4 is detachably connected to the box body 1 and the parachute compartment 3, respectively. The rear of the parachute compartment 3 is electromagnetically connected to a guide parachute compartment 5. A guide parachute 51 disposed within the guide parachute compartment 5 is connected to a parachute 31 disposed within the parachute compartment 3 via a rope. Specifically, the guide parachute compartment 5 is made of ferromagnetic material, and the parachute compartment 3 is provided with an electromagnetic lock connected to the guide parachute compartment 5. The electromagnetic lock can be used to connect or disconnect the power supply to achieve connection or separation between the parachute compartment 3 and the guide parachute compartment 5. It should be noted that this transport drone must be carried by a carrier aircraft and flown to the vicinity of the target airspace. The drone is then launched at an initial speed and altitude. After release, the glider 2 unfolds and glides toward the target area. Upon reaching the predetermined target location and altitude, the guide parachute pod 5 separates from the parachute pod 3. Airflow enters the guide parachute pod 5 from the position between the two, causing the guide parachute inside the pod to inflate and open from the rear of the guide parachute pod 5. Simultaneously, the parachute is pulled out of the parachute pod 3 by the traction of the cable. The airflow then opens the parachute, changing the drone's flight attitude to a vertical landing. The parachute then slowly descends vertically to the target location, effectively improving delivery accuracy. Furthermore, the parachute 31 can be further connected to the cargo hold 4 via a cable to prevent it from slipping. The combined design of the box body 1, parachute pod 3, guide parachute pod 5, and cargo hold 4 facilitates maintenance, replacement, and reuse.

[0024] Furthermore, in specific implementation, Figure 1-6 As shown, the hang glider 2 provided in this embodiment of the present invention includes a left wing panel 21 and a right wing panel 22. The left wing panel 21 and the right wing panel 22 are rotatably connected to a pin 24 provided within the housing 1 via a coil spring 23. Preferably, a wing panel lock 11 is provided within the housing 1 and is electromagnetically connected to the left wing panel 21 and the right wing panel 22. Specifically, the hang glider 2 is also made of ferromagnetic material. The wing panel lock 11 is connected and disconnected by turning the power on and off to lock or unlock the hang glider 2. The coil spring 23 utilizes conventional technology, with its inner end secured to the pin 24 and its outer end secured to the left wing panel 21 or the right wing panel 22. Before the drone is launched, the hang glider 2 is stored in the box body 1, and the wing lock 11 is energized. The left wing 21 and the right wing 22 are both attracted and locked by the wing lock 11. At this time, the coiled spring 23 is rolled and contracted to store elastic restoring force. After the drone is launched, the wing lock 11 loses power, and the locks on the left wing 21 and the right wing 22 are released. Under the action of the elastic restoring force of the coiled spring 23, the left wing 21 and the right wing 22 are respectively unfolded outward.

[0025] Furthermore, in specific implementation, Figure 4 、 5 As shown, the housing 1 provided in this embodiment of the utility model is divided into two layers by a partition 12. The upper housing 1 houses a processing circuit 13, while the lower housing 1 houses a hang glider 2 and a battery 14. The housing 1 is provided with an interface 15, which is electrically connected to the battery 14 via the processing circuit 13. Specifically, the interface 15 connects to the carrier aircraft to charge the battery 14, which also provides power to the processing circuit 13. It should be noted that the interface 15 can be connected to ground equipment. On the ground, an electrical signal can be used to activate the entire circuit, which is powered by the battery 14. This activates the wing lock 11, allowing the hang glider 2 to be stowed into the housing 1 on the ground for easy loading onto the carrier aircraft. Furthermore, flight data can be written to the processing circuit 13 via ground equipment before loading onto the carrier aircraft, making it easier to use on low-end carrier aircraft that cannot transmit data. Furthermore, the interface 15 can also be connected to the carrier aircraft. During flight, the carrier aircraft can send information to the processing circuit 13 via the interface 15 to adjust the target location and altitude to accommodate changes in the mission.

[0026] When launching the drone, the gravity of the drone disconnects the interface 15 from the carrier aircraft. Preferably, a propeller 16 is provided at the front end of the box body 1, and a generator 17 is disposed within the box body 1, rotatably connected to the propeller 16. The generator 17 is electrically connected to the battery 14 via the processing circuit 13. During flight, the airflow drives the propeller 16 to rotate, driving the generator 17 to generate electricity, which in turn powers the processing circuit 13 or charges the battery 14 via the processing circuit 13. This not only provides stable power support but also extends the drone's endurance in low-power mode, maintaining normal operation.

[0027] Furthermore, in specific implementation, Figure 3 、 6 As shown, the hang glider 2 provided in this embodiment of the present invention is flipped and connected to an aileron board 25. A servo 26 is provided below the hang glider 2. The servo 26 pulls a rudder angle 28 provided below the aileron board 25 via a rudder bar 27 to drive the aileron board 25 to flip. Specifically, the servo 26 rotates back and forth, thereby driving the rudder bar 27 to pull the rudder angle 28, adjusting the pitch angle of the aileron board 25, thereby controlling the unmanned gliding posture and ensuring accurate arrival at the target location.

[0028] Furthermore, in specific implementation, Figure 1-5 As shown, the lower portion of the box body 1 provided in this embodiment of the present invention is provided with a hanging ring 6 for clamping and connecting to the cargo hold 4. The front end of the parachute capsule 3 is provided with an anchor point 32 for hanging the cargo hold 4. Specifically, the hanging ring 6 can be in the form of a clamp to achieve a secure connection to the cargo hold 4. Meanwhile, the anchor point 32 is in the form of a buckle to cooperate with the cargo hold 4. This provides a stable and reliable connection to the cargo hold 4, preventing accidental detachment and further ensuring the reliability of the airdrop.

[0029] Further, in the specific implementation, as shown in the box body 1 tail part provided by the embodiment of the utility model is provided with tail wing 10, and the outer wall of the guide parachute cabin 5 is provided with stabilizer surface 50. The tail wing 10 and the stabilizer surface 50 are arranged to enhance the stability of the unmanned aerial vehicle, improve the flight control, so that the high flight stability can still be maintained under the complex climate conditions. Figure 1-5

[0030] The specific working process of the utility model is that after the carrier reaches the predetermined release area, the unmanned aerial vehicle is released, the interface 15 is disconnected with the carrier, the wing plate lock 11 is controlled to lose power by the processing circuit 13, the locking of the glider wing 2 is released, the left wing plate 21 and the right wing plate 22 are unfolded, the unmanned aerial vehicle glides to the target location, when reaching the target position and height, the connection between the guide parachute cabin 5 and the landing parachute cabin 3 is disconnected, and then the guide parachute 51 and the landing parachute 31 are unfolded in sequence, so that the unmanned aerial vehicle slowly lands at the pointed position.​
