Description

Technical Field

[0001] This application relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV equipped with a fairing. Background Technology

[0002] In the field of drones, fairings play a crucial role. They not only provide some protection for the internal equipment of the drone, but also effectively guide airflow, reduce air resistance during drone movement, and ensure overall aerodynamic performance.

[0003] In some drone launches using launch tubes, the drone is propelled from the launch tube using gas ejection to give it initial velocity. During launch, the drone must first break through a fragile cover on the launch tube. Due to the high ejection speed, the drone's fairing will collide with the fragile cover first. While fairings are typically lightweight and structurally strong, there is still a chance of damage during the collision, which could affect the drone's internal equipment or degrade its aerodynamic performance. Utility Model Content

[0004] In view of this, this application provides a drone equipped with a fairing, which, by setting a head cover frame that can extend out of the fairing, allows the frame to break through the fragile cover of the launch tube.

[0005] The following technical solution is adopted in this application: A drone equipped with a fairing includes a drone body, a cross-shaped nose cone frame at the front end of the drone body, a fairing fitted on the front of the drone, a cross-shaped slot at the front end of the fairing corresponding to the cross-shaped nose cone frame, and the cross-shaped nose cone frame extending through the cross-shaped slot.

[0006] Furthermore, the side cross-section of the cross-shaped headgear frame is triangular or trapezoidal.

[0007] Furthermore, a viewing window is provided at the lower part of the fairing.

[0008] Furthermore, a reinforcing rib is provided around the inner edge of the viewing window.

[0009] Furthermore, the cross-section of the reinforcing rib is semi-circular.

[0010] Furthermore, the drone body is provided with several locking pins, and the rear end of the fairing is provided with several locking holes corresponding to the locking pins.

[0011] The beneficial effects of this application are: In this application, by setting a cross-shaped head cover frame that can extend through the fairing at the front end of the UAV body, the cross-shaped head cover frame can make contact with the fragile cover first when the UAV is launched from the launch tube, and successfully break the fragile cover, effectively avoiding the problem of fairing damage caused by the fairing body contacting the fragile cover.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0017] To facilitate understanding of this application, the background technology is further explained below. In the field of unmanned aerial vehicles (UAVs), fairings play a crucial role. They not only provide protection for the internal equipment of the UAV but also effectively guide airflow, reduce air resistance during UAV movement, and ensure overall aerodynamic performance. The materials and manufacturing processes used in the fairing significantly impact its quality and performance. Regarding materials, fairings are often manufactured using composite materials such as carbon fiber, glass fiber, and Kevlar to meet requirements for high strength, lightweight, and corrosion resistance. In terms of manufacturing processes, advanced composite material manufacturing technologies are commonly employed, such as automated manufacturing, prepreg technology, and RTM (resin thermoforming). Among these, RTM technology is one of the most advanced and efficient technologies. It enables high-quality, rapid manufacturing of fairings and is also environmentally friendly, largely solving the environmental and cost issues associated with traditional composite material manufacturing processes.

[0018] The main launch methods for drones are as follows: Hand-launched: Simple to operate and suitable for small drones. The operator holds the drone in their hand and throws it directly into the air.

[0019] Zero-length launch: A rocket booster is installed under the drone, and the drone is released after reaching a certain speed.

[0020] Catapult launch: Launching a drone using a catapult, suitable for heavier drones.

[0021] Rail launch: This method accelerates the takeoff of drones using a rail and is commonly used for large drones.

[0022] Vertical takeoff: A takeoff method similar to that of a helicopter, suitable for drones that need to take off in confined spaces.

[0023] Air launch from mother aircraft: The UAV is launched into the air from the mother aircraft and then released.

[0024] Container launch: The drone is stored on a launch vehicle and launched like a cannonball.

[0025] These launch methods each have their own characteristics and are suitable for different types of drones and mission requirements.

[0026] In some drone launches using launch tubes, the drone is propelled from the tube using gas ejection to gain initial velocity. During launch, the drone must first break through a fragile cover on the launch tube. Due to the high ejection speed, the drone's fairing will collide with the fragile cover first. While fairings are typically lightweight and structurally strong, there is still a chance of damage during the collision, potentially affecting internal drone equipment or degrading aerodynamic performance.

[0027] Reference Figure 1-2 This application provides a drone equipped with a fairing 2, including a drone body, a cross-shaped head cover frame at the front end of the drone body, a fairing 2 fitted on the front of the drone, and a cross-shaped slot 21 at the front end of the fairing 2 corresponding to the cross-shaped head cover frame, through which the cross-shaped head cover frame protrudes.

[0028] Specifically, in this application, a cross-shaped head cover frame 1 that can protrude through the fairing 2 is set at the front end of the UAV body, so that when the UAV is launched from the launch tube, the cross-shaped head cover frame 1 can contact the fragile cover first and break the fragile cover smoothly, effectively avoiding the problem of fairing 2 being damaged due to contact between the fairing 2 body and the fragile cover.

[0029] Reference Figure 1 It is understood that the side cross-section of the cross-shaped headgear frame 1 can be triangular or trapezoidal.

[0030] Specifically, the side of the cross-shaped helmet frame 1 described in this application refers to the side of the cross-shaped helmet frame 1 that can directly contact the fragile cover of the launch tube. The cross section of this side is set as a triangle or trapezoid, which can reduce the contact area between the side and the fragile cover, thereby increasing the impact pressure, so that the cross-shaped helmet frame 1 can break through the fragile cover more quickly, allowing the UAV to launch smoothly and avoiding damage to the fairing 2.

[0031] Reference Figure 2 It is understood that a viewing window 22 may be provided at the lower part of the fairing 2.

[0032] Specifically, since a rotating gimbal is usually installed on the body of a drone, and visible light or infrared light guidance equipment is installed on the gimbal to meet the combat needs of the drone, in order to meet the rotational movement of the gimbal, a viewing window 22 can be opened in the lower part of the fairing 2. The size of the viewing window 22 can be set according to the size of the gimbal and the rotation range of the gimbal.

[0033] Reference Figure 2 It is understood that a reinforcing rib 23 may be provided around the inner edge of the viewing window 22.

[0034] Specifically, a reinforcing rib 23 is provided at the viewing window 22 of the fairing 2, where it is easily subjected to large external forces, to improve its strength and stability and ensure that the fairing 2 is firm and reliable under harsh working conditions.

[0035] It is understood that the cross-section of the reinforcing rib 23 can be semi-circular.

[0036] Specifically, the reinforcing rib 23 has a semi-circular cross-sectional shape, which allows it to fit better with the fairing 2 and enhances the connection strength. The reinforcing rib 23 and the fairing 2 can be connected by integral molding, which can eliminate connection gaps and improve the overall integrity and reliability of the structure.

[0037] Reference Figure 2 The drone body may be provided with a number of locking pins, and the rear end of the fairing 2 may be provided with a number of locking holes 24 corresponding to the locking pins.

[0038] Specifically, the fairing 2 is connected to the UAV body by a pin and a hole 24. The pin is inserted into the hole 24. This connection method is simple in structure and easy to operate, and can be easily and conveniently disassembled and replaced when the fairing 2 is damaged.

The embodiments and features described therein can be arbitrarily combined without conflict. The scope of protection of this application should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims.
