Abstract

The utility model relates to the field of unmanned aircraft equipment, more specifically to a device for dropping cargo from an aircraft. Also refers to equipment in aircraft that enables the detachment, transportation or dropping of objects. The technical result that the proposed device is aimed at achieving is ensuring the reliability of fixation and undocking of the load when it is dropped. Distinctive features of the proposed device for transporting and discharging cargo from an aircraft are the presence of an ultimate type of fastening for securing the cargo in the device and the presence of a universal connecting unit for power elements.

Description

The utility model relates to the field of unmanned aircraft equipment, more specifically to a device for dropping cargo from an aircraft. Also refers to equipment in aircraft that enables the detachment, transportation or dropping of objects.

A device for securing and releasing cargo from an aircraft is known - invention RU No. 2402460 C1. In a device for fastening and releasing cargo from an aircraft, containing front and rear fastening units made in the form of pneumatic cylinders mounted on the aircraft, the supra-piston cavities communicate with autonomous pyrotechnic devices for supplying compressed gas, the cargo contains fastening brackets, and the outer ends of the rods are equipped with threaded connections for attaching brackets, while the load has contact surfaces to rest against the structure of the aircraft when tightening the threaded connections, the rods are fixed motionless by fastening devices with the possibility of being released due to the movement of the corresponding pistons under the influence of compressed gas pressure and separation together with the load, the front unit is made with the possibility of transmitting to the load a greater impulse of force than the impulse transmitted to the load by the rear assembly, while the load securing brackets and at least one of the rods are equipped with hinges, the rotation axes of which are perpendicular to the repulsion plane. In addition, one of the fastening brackets is designed to compensate for temperature changes in the length of the load.

A significant similar feature of the proposed device is that the useful device has a load securing unit due to fixation in it using an eye mounted on the load itself. The disadvantages of this prototype of the invention can be considered: large overall dimensions; attachment to one type of mechanism that ensures the release of cargo (pyrotechnic devices); possible misalignment of the rod axes, which can lead to blocking of the load in the mechanism.

A device for transporting and dumping cargo is known, containing a load securing unit with a device, an additional cargo securing unit with a device, a power element according to patent RU2244663, selected as a prototype.

The technical result that the proposed device is aimed at achieving is ensuring reliable fixation.

Distinctive features of the proposed device for transporting and discharging cargo from an aircraft are that the cargo securing unit contains levers designed to clamp the cargo eye knuckle, and the additional cargo securing unit is made in the form of a bar with the possibility of its fixation by a spring, the bar being made with the possibility of fixing the levers in the closed position, while the device also contains a mount for the power element.

The proposed technical solution can be used in aircraft, mainly unmanned, for attaching cargo outside the aircraft with the possibility of its rapid separation from the aircraft. The device can be used to transport cargo or to deliver cargo and drop it at the delivery point without the need for the aircraft to land.

The device is shown in Figs 1-6.

In fig. Figure 1 shows a section of the device and the location of the cam of the cargo eye of the load (12) in the internal space of the device. In the initial position, when the fist of the cargo eye (12) is fixed in the device, the levers (4) clamp the fist (12) and do not allow vertical and horizontal movements of the load associated with the fist (12).

In fig. 2-4 element (12) has been removed for clarity of the device. In the closed position, the bar (9) is fixed parallel to the horizontal plane due to the spring (6), at the same time the bar is fixed in the position of the levers (4) as shown in Fig. 3, which prevents the knuckle of the cargo eye of the load (12) from moving in a vertical plane, that is, it fixes the load.

When force is applied to the drive cable (13), fixed to the fork (10), the bar (9) rotates around its axis (11), which is divided into 2 components, fixed in the corners (14), while the bar (9) goes into the open position shown in Fig. 5. After the bar (9) moves to the open position, the spring (7) begins to compress and rotate the levers (4) around their axes (5). Afterwards, the fist of the cargo eye (12) can freely exit the internal space of the useful device. To ensure reliable exit of the cargo eye knuckle (12), guides (15) are provided, mounted on the side plates (2), guides (15) are shown in Fig. 6.
