Description

Technical Field

[0001] The utility model relates to the technical field of airborne delivery equipment, in particular to an airborne delivery and recovery device. Background Art

[0002] Airborne pods are streamlined nacelles installed on the outside of aircraft such as airplanes, helicopters, and drones, usually suspended under the fuselage or wings. These pods are loaded with specific airborne equipment or weapon systems and are designed to expand or enhance the mission execution capabilities of the aircraft.

[0003] The Chinese patent with application number CN202311332777.3 discloses an emergency pod for unmanned aerial vehicles, including a front pod, a rear pod and an intermediate pod; the front pod, the rear pod and the intermediate pod form a whole; the front pod is composed of a longitudinal beam, a skin and a cover plate; the rear pod is composed of a longitudinal beam, a skin and a cover plate; the intermediate pod is divided into an upper pod and a lower pod, the upper pod is composed of a longitudinal beam, a skin, a cover plate and an upper floor, and the lower pod is composed of a skin and a lower floor; emergency communication equipment is integrated in the whole composed of the front pod, the rear pod and the intermediate pod, which is used to establish an emergency communication guarantee mechanism when a communication failure occurs; connecting fasteners are integrated on the longitudinal beams of the intermediate pod, and the connecting fasteners are used to connect with the hanging points of the unmanned aerial vehicle. The present invention realizes the standardized hanging method of the emergency pod and the aircraft through the connecting fasteners, integrates the emergency communication equipment into the pod, realizes the air emergency communication function, and the skin in the pod plays a rectifying role, reducing the influence of the hanging pod on the flight performance of the aircraft.

[0004] The existing pods still have the following problems:

[0005] 1. In order to reduce the air resistance of the pod as much as possible, the outer shell (skin) of the pod is generally divided into three sections, forming a shell shaped like a bullet. However, since the skin itself is relatively thin, gaps will inevitably exist in the three sections of the skin during the actual connection process, resulting in poor sealing of the shell. When performing a delivery mission in rainy or humid environments, moisture will enter the interior of the shell through these gaps, which will not only affect the delivery of materials, but also affect the electrical components inside the pod, and after a long time, it will cause component failure.

[0006] 2. The replacement of the skin itself needs to be considered. When a drone or helicopter is performing a mission, it is inevitable to encounter a flock of birds. When the pod collides with a flock of birds, the skin on the head can easily collapse, causing a larger gap between the head skin and the middle skin, further reducing the sealing of the pod. At the same time, the skins are generally connected by multiple sets of bolts, and the subsequent replacement of the skins is very troublesome. Utility Model Content
