Description

[Detailed Description of the Invention] This invention relates to a device for ejecting a payload such as a smoke marker from an aircraft such as a helicopter.

Conventional marker emitting devices have been designed to eject the markers stored vertically downward while maintaining the same position, resulting in a drawback that the height of the storage container becomes large.

Therefore, the object of this invention is to obtain a firing device that can store a marker horizontally in a container and eject it downward while keeping it horizontal.

To explain this invention based on the drawings, the marker firing device 1 of this invention consists of a container 2 having a cylindrical shape as a whole.
A lug 6 is attached to a beam 5 that runs vertically across the top of the container 2 so that it can be suspended on a pylon 4 of a helicopter 3. The container 2 consists of a main body 9 between the front and rear partition walls 7 and 8, a nose cover 10 and a tail cover 11 at the front and rear thereof. Main body part 9
is divided into two chambers 13 and 14 by a central partition wall 12, and six cylindrical markers 15 (i.e., loaded items) can be stored in each chamber along the inner peripheral surface of the container 2. It's summery. Note that the marker 15 is connected to the guide rail 17 in the front and back direction, and by the guide frame 16 and the cylindrical case 2 in the radial direction.
7 (described later).

At the bottom of the container 2, there is a door 19 for each chamber 13, 14. The door 19 has a size that allows only one marker 15 to pass through, and as shown in FIG.
One side is pivoted parallel to the container and opens downward. A spring 20 is attached to the pivot portion of the door 19, and this spring biases the door 19 in a closed state. 21 is door 1
It is a lock mechanism to keep 9 in the closed state,
By sending air to the door cylinder 22, the lock can be released. Furthermore, an injection cylinder 23 is placed on the center line in each chamber 13, 14 within the container. Air to be supplied to these cylinders is stored in an accumulator 24 housed inside the nose cover 10.

When injecting the marker 15, use the door cylinder 2.
Send air to 2. This cylinder 22 then extends and the locking mechanism 21 of the door 19 is released. On the other hand, almost at the same time as the door cylinder 22 extends,
Air passes through this cylinder 22 and enters the injection cylinder 23 from the pipe 25, and the piston 23a of this cylinder moves rapidly downward. Along with this movement of the piston, the marker 1 directly above the door 19
5 is injected out of the container while pushing open the door 19 downward. (Figure 3 chain line). Next, when the air supply is cut off, the injection cylinder 23 is contracted by the force of the built-in spring, and the door 19 is closed by the force of the spring 20, while the door cylinder 22 is closed by the force of the spring 20.
The locking mechanism 21 is also contracted to engage the door 19.

In this way, after the marker directly above the door 19 has been ejected out of the container, in order to eject the next marker, it is necessary to transfer the remaining marker 15 directly above the door, and then Explain. container 2
A pair of left and right rods 26 are rotatably mounted on the central axis of the cylindrical case 27, and each rod 26 is rotated downward by a spring 28 (see Fig. 1) housed in a cylindrical case 27. is encouraged to do so. The tip of each rod 26 is in contact with the marker 15 at the top, so that the marker 15 in the container 2 is connected to the rod 2.
6 is biased downward. Furthermore, a pair of left and right cams 29 are pivotally attached to the spring case 27 at points 30. Each cam 29 is further pivotally connected at point 31 to a piston rod 32a of a charge cylinder 32. Each charge cylinder 32 is normally extended by the action of a built-in spring, so the cam 29 is in the solid line position in Figure 4, between the loaded object directly above the door and the loaded object next to it. It fits in and positions the marker directly above the door in a fixed position, and when the marker is ejected, it holds the markers on either side of it in that position.

When the marker 15 is ejected and the door 19 is closed and locked, air is sent to the desired charge cylinder 32 on either the left or right side, which contracts.
The cam 29 rotates as shown by the chain line in FIG. 4 and is removed from the marker 15. Then, the marker 19 remaining in the container is sent downward by the rod 26, and the marker 15 is placed directly above the door 19. In this state, the air supply to the charge cylinder 32 is stopped, and the cam 2
When 9 is returned to the solid line position in FIG. 4, preparations for dropping the next marker are completed. In this way, the markers contained within the container are ejected one after another.

As explained above, according to this invention, the loaded object (marker) is stored parallel to the inner peripheral surface of the cylindrical container, so even if the container has a relatively small diameter, the loaded object can be stored. Can store many items. Moreover, when the loaded object is injected by the cylinder, it moves out of the container while pushing the door open, so there is no particular need for a door opening/closing drive device, resulting in a simple structure as a whole. In addition, in order to transfer the loaded items in the container directly above the door, the uppermost loaded item is pushed down using a rod that is biased by a spring, which simplifies the structure.
In addition, since it has a cam that fits between the loaded item directly above the door and the loaded item next to it, not only can the loaded item directly above the door be positioned in a fixed position, but also when the loaded item is ejected, The load can be held in place until the door is closed and ready for reception, ensuring reliable operation.
