When the accompanying objects are thrown out at different speeds and angular velocities, the rocket or aircraft will produce micromotion. By studying the speed and angular velocity of the accompanying objects when they are released, we can study the micromotion boundary conditions of the aircraft or rocket.

[0047] Please refer to Figure 1 and Figure 2, an embodiment of the present invention provides a throwing device, including a launching energy storage unit and a rotating unit;

[0048] The rotating unit includes a cylinder 1 and a covering body 2. The inner wall of the cylinder 1 is provided with a spiral groove 11 spirally distributed around its axis. The inner wall of the covering body 2 includes a cavity matching the shape of the ejection 3. The outer dimensions of the covering body 2 match the dimensions of the inner wall of the cylinder 1. The covering body 2 is provided with a protrusion 21, which matches the spiral groove 11 and is inserted into the spiral groove 11.

[0049] The launch energy storage unit is used to apply a force along the axis direction of the cylinder 1 to the covering body 2 in the cylinder 1;

[0050] When throwing out the ejecta 3, the launching energy storage unit applies a force along the axial direction of the cylinder 1 to the coating 2 in the cylinder 1, so that it is launched to the outside of the cylinder 1. In the process of the coating 2 carrying the ejecta 3 moving in the cylinder 1, the spiral groove 11 and the protrusion 21 cooperate to make the coating 2 carrying the ejecta 3 rotate and obtain an angular velocity.

[0051] In this embodiment, a launching energy storage unit is used to provide power for the coating 2 with the built-in ejecta 3, that is, to provide a linear velocity along the axial direction of the cylinder 1. The launching energy storage unit can be powered by a spring, by gas expansion, or by electromagnetic power. When the coating 2 with the built-in ejecta 3 moves in the cylinder 1, the protrusion 21 will control the rotation of the coating 2 with the built-in ejecta 3 under the action of the spiral groove 11 to obtain an angular velocity. In summary, the device provided in this application can be used to throw an ejecta 3 with a linear velocity and an angular velocity.

The first column 52 is fixedly installed on the bottom plate 12 of the cylinder 1. The first column 52 is provided with a through hole, and the second column 53 is provided with a limiting hole. The locking release column 54 passes through the through hole and enters the limiting hole. The cam 51, the locking release column 54, the through hole and the limiting hole are located in the same plane. The locking support column sleeve is provided with a second spring 55. A power disk 57 is installed at one end of the second column 53. The first spring 4 is between the power disk 57 and the bottom plate 12;

[0056] When the ejected object 3 is not released, the protrusion 21 of the cam 51 abuts against one end of the locking release column 54, and the second spring 55 sleeved on the locking release column 54 is in a compressed state. When the ejected object 3 is released, the servo 56 rotates the cam 51, and one end of the locking release column 54 abuts against the recessed part of the cam 51 under the elastic force of the second spring 55, and the other end of the locking release column 54 pops out from the limiting hole, releasing the connection between the first column 52 and the second column 53. The second column 53 and the power disk 57 are displaced and exerted force under the elastic force of the first spring 4, so that the covering body 2 coated with the ejected object 3 on one side of the power disk 57 is thrown out.

[0057] In this embodiment, the locking and releasing device 5 can be used to lock and release the first spring 4, so that the ejection can be controlled.

[0058] In some embodiments of the present invention, a guide member 41 is disposed outside the first spring 4 .

[0064] In this embodiment, the four groups of components that are evenly distributed can make the overall structure and force generation more uniform.

[0065] In some embodiments of the present invention, the enclosure 2 includes a first half enclosure 2 , a second half enclosure 2 and an annular hoop, on which a protrusion 21 is provided, and the annular hoop is used to tighten the first half enclosure 2 and the second half enclosure 2 .

[0066] In this embodiment, the enclosure 2 consisting of the first half enclosure 2 and the second half enclosure 2 is fastened by an annular hoop, which facilitates the installation and removal of the heavy ejecta 3 .

[0067] In some embodiments of the present invention, four evenly distributed first springs 4 are included.
