Description

Rocket launch inspection system and rocket launch inspection method using the same

The present invention relates to a rocket launch inspection system and a rocket launch inspection method using the same. The present invention relates to a rocket launch inspection system capable of integrally inspecting a rocket launch process, and a rocket launch inspection method using the same.

A typical rocket launch process is to mount the rocket on the launch tube of the launch device, connect a micro-resistance meter to the launch device to measure the contact resistance of the igniter, cable, and detent, and then use the launch device to squib the igniter required. When (squib) is supplied, the propellant is burned and the rocket is propelled.

The resistance of the igniter and the current supplied to the squib may vary depending on the specifications of the rocket. For example, in a 70 mm (2.75 inch) new rocket, the internal resistance of the igniter is around 1.0 Ω, and a current of 1.5 A or more must be supplied to stably ignite the motor. Therefore, the launch device of the rocket must supply sufficient current considering the contact resistance of the igniter, the cable and the detent.

However, during actual rocket launch, the resistance value increases due to combustion materials deposited on the launch tube, ignition characteristics of the motor, instability of the supplied current, and poor contact, and the rocket may be launched abnormally. In particular, there are many connection parts such as cables, connectors, and detents between the launch device and the rocket, and bullets may be deposited inside the launch tube due to combustion of the propellant. In addition, due to this, contact failure may occur and the ignition may not be possible.

In addition, when a low-temperature treated rocket is mounted on a launch tube heated by rocket launch, the resistance value may exceed the standard due to condensation. This may result in a hang fire or misfire of the rocket.

However, in the prior art, if the igniter, cable, and detent contact resistance exceed the standard after the rocket is mounted on the launch tube, the rocket is removed from the launch tube and the launch tube detent is cleaned, or the rocket is mounted in another hole of the launch tube and fired. . In addition, since there is no way to check whether the launch device supplies an appropriate squib, a system capable of integrally checking rocket launch is required.

The above-mentioned background art is technical information that the inventor possessed for the purpose of derivation of the present invention or acquired during the derivation of the present invention, and cannot necessarily be said to be a known technique disclosed to the general public prior to the filing of the present invention.

Accordingly, the circuit to which the squib is supplied from the launch device 200 may be configured between the first contact 312a and the second contact 312b or between the first contact 312a and the third contact 312c. . Here, the positions of the second contact point 312b and the third contact point 312c may vary depending on the type of the rocket R to be checked.

That is, the simulated rocket 310 according to an embodiment of the present invention may implement a squib contact portion in which different types of real rockets R come into contact with the launch tube 100 . Accordingly, the rocket launch inspection system 10 according to an embodiment of the present invention performs inspection on different types of actual rockets R without replacing the inspection device 300 mounted on the launch tube 100 . can

In FIG. 4, only two contacts of the second contact 312b and the third contact 312c are shown except for the first contact 312a functioning as a ground, but the number is not particularly limited. For example, if there are three or more types of the actual rocket R to be simulated, the corresponding contact points may also be three or more.

In an embodiment, the squib contact part 312 may be detachably disposed with respect to the housing 311 . That is, the first contact 312a, the second contact 312b, and the third contact 312c of the squib contact unit 312 may be interchangeable.

In one embodiment, the connection part 313 may be provided with a handle (not shown) on the outside. Accordingly, the user can easily insert or remove the simulation rocket 310 with respect to the launch tube 100 by gripping the connection part 313 .

In one embodiment, the connection part 313 may be configured to be detachable from the housing 311 .

The ignition circuit insulation unit 314 prevents the squib supplied from the launch device 200 from electrically interfering with the check circuit 320 to be described later. To this end, the ignition circuit insulating part 314 may be formed of an insulator.

The indicator 315 may be disposed at the end of the simulation rocket 310 to indicate the voltage and current of the supplied squib. For example, as shown in FIG. 4 , the indicator 315 may be connected to an end of the housing 311 through a connection part 313 . In one embodiment, the indicator 315 may be in a state protruding to the outside of the firing hole (110).

The check circuit 320 is connected to a circuit to which the squib is supplied from the launch device 200 , measures the current and voltage of the squib supplied from the launch device 200 , and the launch tube 100 and the check device 300 . It is possible to measure the resistance or the like between the launch tube 100 and the launch device 200 . Here, the resistance between the firing tube 100 and the inspection device 300 may include a contact resistance between the squib contact portion 312 of the firing tube 100 inspection device 300 . Here, the resistance between the launch tube 100 and the launch device 200 may include the resistance of the cable C connecting the launch tube 100 and the launch device 200 .

The check circuit 320 may be disposed inside the simulation rocket 310 , more specifically, inside the housing 311 .

The resistance switching unit 321 controls the resistance of the inspection device 300 . For example, the resistance switching unit 321 may operate to selectively connect an internal resistance unit 322 to be described later to the check circuit 320 .

More specifically, for example, the resistance switching unit 321 may operate such that the check circuit 320 is connected to an internal resistance unit 322 to be described later. When the squib is supplied in this state, the measuring unit 325 to be described later may measure the voltage and current of the supplied squib, and the indicator 315 may display the measured voltage and current of the squib.

Alternatively, the resistance switching unit 321 may operate so that the check circuit 320 is not connected to the internal resistance unit 322 . In this case, the resistance of the inspection device 300 may be substantially zero. Here, the meaning of "substantially 0" includes not only the case where the resistance value is 0 in the strict sense, but also the case where the resistance value has a microscopic size that hardly affects the measurement result. In this state, the measuring unit 325 may measure the contact resistance between the launch tube 100 and the launch device 200 or the resistance of the cable C.

That is, the rocket launch inspection system 10 according to an embodiment of the present invention changes the resistance value of the inspection device 300 using the resistance switching unit 321, and not only the voltage and current of the squib, but also the rocket launch inspection system The resistance of (10) can be measured.
