It relates to a pyro fixed separation device.

In general, for the separation of satellites / projectiles, a separation nut or a separation bolt is often used by separation of the bolt notching site due to the ignition bomber. In this case, the pressure caused by the igniter to cut the tension bolt should be large, the pyro impact caused by the break of the bolt is very large, and there are disadvantages that a lot of debris is generated.

In addition, a separation device that is used in many stages of separation of the projectile is performed by applying a linear powder such as ESMDC or LSC in addition to the separation nut or separation bolt. In case of such a linear gunpowder, the pyro impact caused by the large amount of gunpowder is very large, and there are disadvantages in that a lot of fragments are generated.

The induction of such a large Pyro impact can cause malfunctions of projectiles or satellite-mounted electronic equipments, and further countermeasures have to be prepared, which is disadvantageous in terms of time and cost. Incidental debris can also affect satellites or upper stage payloads during separation, requiring additional structural design to prevent this, leading to increased weight and design complexity.

As the second housing 500 moves downward when the igniter operates, the restraint of the separation nut 400 is released to separate the tension bolt 300.

Although not shown, a female screw portion is formed on the lower inner circumference of the first housing 100, and a male screw portion is formed on the outer circumferential surface of the base 200 to correspond to the female screw portion.

In addition, a male screw portion is formed on an upper outer circumferential surface of the tension bolt 300, and a female screw portion is formed on an inner circumferential surface of the separation nut 400.

The first housing 100 includes a plurality of reference holes 110 spaced apart from each other vertically on the outer circumferential surface; And a coupling step 120 formed at a lower outer peripheral edge thereof.

The present invention may be difficult to know exactly the assembled state of the interior due to the nature of the configuration.

Therefore, as shown in FIG. 1, two reference holes 110 are formed on the outer circumferential surface of the first housing 100, and the two housings are located at the same height when assembling the second housing 500. It is preferable to form a reference groove 510, so that the reference groove 510 can be seen through the reference hole 110.

Here, the separation interval of the reference hole 110 and the reference groove 510 is defined as the distance that the second housing 500 is finally moved when the pyro fixing separator according to the present invention.

 Therefore, in the assembled state, it may be confirmed that the assembly is normally performed only when the reference hole 110 and the reference groove 510 of the second housing 500 and the first housing 100 are exactly matched, and after the separation, the first housing When the reference hole 110 formed in the lower portion of the housing 100 and the reference groove 510 formed in the upper portion of the second housing 500 coincide with each other, it may be confirmed that the correct separation operation is completed.

As shown in FIGS. 1 and 4, the base 200 has a seating support groove 210 in which a lower portion of the second housing 500 is seated and supported when the second housing 500 moves downward.

As shown in Figure 3, the separating nut 400, the protrusions 410 are formed in each of the upper and lower peripheral edges, separated into three pieces at 120 ° intervals, the upper end of the separation nut 400 The protrusion 410 installed at the outer circumference is formed to be inclined from the outer upper portion to the inner lower portion.

In addition, the second housing 500 is formed with a groove such that sealing means is coupled to the contact portions of the first housing 100 and the third housing 600, a plurality of reference grooves at regular intervals up and down on the outer peripheral surface 510 is formed, and a plurality of protruding contact portions 520 contacting the outer circumferential surface of the protrusion 410 is formed below the inner circumferential surface.

In addition, the lower surface of the outer step 610 formed in the lower portion of the third housing 600 is preferably configured to be in contact with the upper surface of the separation nut 400 by inclining from the outer upper to the inner lower.

Therefore, before separation, the coupling (restraint) of the separation nut 400 and the tension bolt 300 is as shown in Figs. 3 and 4, the protruding contact portion 520 to the outer peripheral surface of the protruding portion 410 It is done by contact.

Hereinafter, the operation state of the present invention will be described in more detail through a separation process (see FIGS. 1 to 5).

1) The second housing 500 moves downward by the internal pressure caused by the detonation of the igniter.

2) The lower portion of the second housing 500 is seated in the seating support groove 210, the elastic means 800 is compressed.

3) The contact surface (520) of the protrusion contact portion 520 and the protrusion 410 is released.

4) The third housing 600 is pressurized downward by the force of the compressed elastic means 800, while pushing the separation nut 400 in the transverse direction, the separation nut 300 in the separation nut 400 is separated.

5) The pusher 700 is moved downward by the internal pressure caused by the detonation of the igniter to push the tension bolt 300.

6) the pusher 700 has a lower body 710 which is in contact with the upper portion of the tension bolt (300); An upper body 720 formed above the lower body 710 and supported by the inner step 620 when the lower body 710 moves downward; And a groove formed on an outer circumferential surface of the upper body 720 to which a sealing means is coupled. Thus, the pusher 700 moved downward has a stepped portion formed at a lower portion of the upper body 720. The pusher 700 stops moving while being supported by the inner step 620 of the housing 600.

7) The tension bolt 300 is completely separated.

On the other hand, the contact portion between the groove and the structure may be configured such as sealing means, the friction force between the second housing 500 and the separating nut 400, spring for releasing restraint of the tension bolt 300 The igniter pressure should be selected to cause a load that is greater than the combined load of the load and the frictional force of the seal.

Here, the spring load can be predicted by the design, and the frictional force of the seal or the like is a very small value, which is negligible.

Therefore, if the friction force between the second housing 500 and the separation nut 400 obtained by water calculation or test can be known, it is possible to easily obtain the pressure of the igniter and easily apply it.

The present invention discussed above is a design concept in such a way to release the constraint of the tension bolt 300 and the separation nut 400 apart from the concept of separating the tension bolt 300 or the frame structure to be directly coupled to the separation. Is applied differently than before.

The operating principle of the present invention forcibly moves the second housing 500 downward by the internal pressure caused by the detonation of the igniter, and thus the second housing 500 and the three separation nuts 400. The release bolt is characterized in that the tension bolt 300 is separated.

At this time, the third housing 600 forcibly moves the three separation nuts 400 in the lateral direction by the compression of the elastic means 800 by the movement of the second housing 500. It serves to further assist the release of the tension bolt 300, and forcibly pushes the tension bolt 300 by the lower movement of the pusher 700 by the internal pressure caused by the ignition explosion Separation is carried out by additional detachment of the bolt 300.

In addition, by applying two groups of igniter by the external environment, only one of the igniter can be configured to release the restraint of the tension bolt 300 can be improved reliability for separation.
