Description

[0001] ELECTRONIC-MECHANICAL ARM-FIRE DEVICE [0002]

The present invention relates to electromechanical ignition safety devices for ignition of propulsion engines.

The rocket ignition safety device is a device for preventing the accidental ignition of the missile to fire and for launching the missile when the required input conditions are met according to the planned launch sequence. Ignition safety devices for rockets comply with the design regulations of MIL-STD-1901A, the propulsion engine ignition system safety standard, and generally contain igniters filled with gunpowder for rocket ignition.

The operating state of the ignition safety device can be classified into a safety state, a charging state, and an ignition state. Generally, the safety state is a state in which the ignition safety device is electrically short-circuited without supplying any power, and a mechanical barrier is provided so that ignition energy is not emitted to the outside of the ignition safety device even if the ignition is ignited .

The charging state means a state in which the mechanical barrier is removed by an electric signal supplied from the outside or can be easily removed by the operation of the igniter, and the electrical short circuit of the igniter is released and the ignition power can be supplied from the outside State.

The ignition state refers to a state in which an ignition signal is supplied in a loaded state and a built-in igniter is operated and gas of high temperature and high pressure which is ignition energy is discharged to the outside of the ignition safety device.

The ignition safety device can be classified into mechanical, electromechanical, electromechanical, or electronic depending on the loading method.

The conventional electromechanical ignition safety device has improved safety concept and improved reliability by applying an ignition safety circuit, an optical sensor, a through bulkhead initiator (TBI), and the like.

Electromechanical ignition safety devices consist of safety circuits, torque motors, ignition tubes, and bulkhead ignitors. To enhance reliability, two bulkhead igniters (TBI) are arranged in parallel and a transfer gun (BKNO ₃ ) And the ignition output powder (BKNO ₃ ) are sequentially ignited to form a final ignition output.

Conventionally, as the structure of the bulkhead igniter, a donor powder and an acceptor powder are positioned adjacent to each other with a bulkhead therebetween. Thus, when an ignition signal is applied to the electric ignition tube in the loaded state and the ignition tube explodes, the pressure of the donor gun, the acceptor gun, and the ignition output gun of the bulkhead igniter are sequentially ignited.

Conventional ignition safety devices can produce relatively the same output even if only one of the two bulkhead ignition devices is ignited. However, the transfer gun and the ignition output gun are double contained in the same kind of explosive (BKNO ₃ ) There is a disadvantage that the manufacturing process becomes complicated because the amount of gunpowder to be consumed is increased to deteriorate the structural stability and the size of the ignition safety device must be increased. In addition, when two electric fire extinguishers explode with a time difference, there arises a problem that the other fire extinguishers are damaged by the first fire extinguisher and the fire is not made.

There is a need for a structurally stable ignition safety device so that a plurality of electric fire extinguishers can be ignited while structurally simplifying the amount of gunpowder installed therein.

According to one example related to the present invention, the barrier wall igniter may be mounted such that the donor powder and the transfer powder are opposed to each other.

According to an example of the present invention, the barrier wall igniter may include a cover formed with a notch at one end thereof and for limiting the external exposure of the transfer gunpowder.

According to an example of the present invention, the barrier wall igniter may be formed to have a spiral portion on an outer surface thereof so as to be detachable from the opening portion of the housing.

According to an example of the present invention, the auxiliary PCB may be positioned so as to overlap with the FPCB to prevent a connection portion between the FPCB and the detonating tube holder from being damaged.

According to the present invention having such a constitution as described above, even if there is no ignition output powder, the igniter can be ignited by the donor powder, the acceptor powder, and the transfer powder, so that it is structurally stable against impact and heat.

In addition, it is possible to rotate by an angle set in the clockwise direction or the counterclockwise direction of the electric fire extinguisher installed in the fire extinguisher holder, so that the mutual position with the baffle igniter can be adjusted to form the safety state, the charging state and the ignition state .

Further, since the ignition portion of the baffle wall igniter is sealed by the lid portion provided with the notch, energy can be effectively transmitted to the outside when the ignition is not exposed to the outside air.

In addition, a separate auxiliary PCB can be reinforced in the holder of an expiratory tube, so that even if one electrical explosive is blown first and the impact due to the explosion is transmitted, the signal can be transmitted more stably to the other holder.

Fig. 1 shows a perspective view of one side of the ignition safety device 100, and Fig. 2 shows a cross-sectional view of the ignition safety device 100. As shown in Fig.

The ignition safety device 100 is a device for preventing the accidental ignition and firing of the missile, and igniting the missile when the required input conditions are satisfied according to the planned launch sequence.

The ignition safety device 100 includes a housing 110, a torque motor 120, an igniter tube holder 130, an ignition safety circuit board 140, and a through bulkhead initiator (TBI) 150 do.

Hereinafter, each configuration of the ignition safety device 100 will be described.

A space portion is formed in the housing 110 and the ignition safety circuit board 140, the torque motor 120, and the detonating tube holder 130 can be mounted. An opening may be formed at one end of the housing 110 and a connector 160 may be coupled to the ignition safety circuit board 140 at the other end to form a moving path of an electrical signal. The housing 110 may be made of a metal material for structural stability.

The torque motor 120 (Torque Motor) is installed inside the housing 110 and serves to transmit rotational force.

The torque motor 120 is an electromagnetic actuator that provides a limited angle of torque and converts the electrical signal into a limited rotation of the rotor 122b. The torque motor 120 is widely used for a scanner, a servo valve, an antenna, a robot driving and the like in the aerospace field due to its simple structure and high reliability.

Fig. 5 shows an exploded view of the torque motor 120. Fig. 5, the torque motor 120 is constituted by a shaft 121, a stator 122a, a rotor 122b, a case 122c, and a coil 122d which form a rotating shaft. An FPCB (Printed Circuit Board) 123 is disposed on the outer circumferential surface of the torque motor 120 so as to be parallel to the shaft 121. The torque motor 120 is fixed to the housing 110. The rotation angle of the torque motor 120 varies depending on the number of poles. In the case of two poles, the rotation angle of the torque motor 120 is within ± 90 ° of the machine angle.

When the charging power is applied to the torque motor 120, the charging state is switched to the charging state within several tens of msec, whereby the electric explosion pipe 131 and the explosive of the bulkhead igniter 150 are aligned.

FIG. 3 is a perspective view illustrating a state where the igniter tube holder 130 is coupled to the torque motor 120, and FIG. 4 is a side view thereof. The igniter tube holder 130 is fitted and fixed to the rotating shaft 121 of the torque motor 120.

The detonator holder 130 serves to support the detonator pipe 131 and the detonator pipe holder 131 is installed inside the detonator holder 130. The electric ignition tube 131 transfers energy for ignition of the baffle igniter.

The rotation shaft 121 of the torque motor 120 is inserted and fixed to the center portion 154 of the armature holder 130. With the rotation of the torque motor 120, the detonator holder 130 can rotate together with the torque motor 120 by a predetermined angle, and the position of the detonator holder 130 relative to the baffle 150 is determined by the rotation of the set angle .

6 is a cross-sectional view showing the internal structure of the electric detonating pipe 131. As shown in Fig.

The electric ignition tube 131 serves to ignite the baffle igniter 150. The electric detonating pipe 131 is spaced radially from the rotating shaft 121 and extends in a direction parallel to the rotating shaft 121.

A plurality of electric ignition tubes 131 may be installed to pass through the ignition tube holder 130 and be spaced apart from the rotation axis 121 of the ignition tube holder 130. Each of the electric fire extinguishers 131 may be symmetric with respect to the rotational axis 121 of the fire extinguisher holder 130 and may be installed to be parallel to each other.

When a current is applied to each of the electric detonating pipes 131 from the ignition safety circuit board 140, after the donor powder 151 is ignited, the acceptor powder 152 and the transfer powder 153 are sequentially ignited The explosion of the barrier wall igniter 150 becomes possible. An optical sensor 133 is provided on one side of the detonating tube holder 130, and the optical sensor 133 serves to recognize the loading state. The detonator holder 130 is connected to the FPCB 123 to receive a signal for detonation.

Referring to FIG. 6, the shape of the electrolytic explosion pipe 131 will be described. The electrolytic explosion pipe 131 is composed of an explosive case and an explosive case (not shown) having a shape to surround the explosive. The electric detonating pipe 131 includes an RF filter 131b, a rubber bearing 131c and a spark ring 131d.

The detonation tube plug 131a has the shape of a wire, and the initiator is positioned adjacent thereto. The ZPP 131f as a high-voltage initiator is a kind of gunpowder, which is filled with high pressure and filled with BN 131e, which is one type of gunpowder, at high pressure so as to cover the ZPP 131f. When the BN 131e is filled on the ZPP 131f, the insulation resistance between the ZPP 131f and the case 122c can be increased. Here, the BN 131e and the ZPP 131f may be the same or different materials.

On one side of the BN 131e, LA (131g) and RDX (131h), which are formed by pressing powder, and which are one kind of explosives, may be located. The detonating tube plug 131a is formed of a wire and functions to introduce a stimulus that can detonate the initiator. Also, in order to prevent static electricity, a spark ring 131d made of stainless steel (SUS303) can be manufactured and inserted to form a discharge gap. The rubber base 131c penetrates the plug 131a and supports the plug 131a. The RF filter 131b prevents the noise of the high frequency from moving when the magnetic pole is introduced, and the RF filter 131b is positioned to be in contact with the rubber bearing 131c.

7 is a cross-sectional view showing the internal structure of the bulkhead icter 150. Fig.

Through-Bulkhead Initiator (TBI) 150 can obtain an output by igniting a gunpowder on the opposite side of the bulkhead using a shock wave generated by explosion of any one of the gunpowder on both sides separated by the metal barrier.

The bulkhead igniter 150 is installed in an opening (not shown) of the housing 110 and is disposed in parallel with the explosion pipe holder 130. A spiral portion (not shown) may be formed on the outer surface of the bulkhead igniter 150 and may be coupled to a spiral portion (not shown) provided on one side of the housing 110. The barrier wall igniter 150 may be detachably coupled to the opening of the housing 110.

A rotary shaft receiving portion 154 is formed at the center of the bulkhead igniter 150 and includes a space portion in which the rotary shaft 121 of the torque motor 120 passing through the center of the explosive tube holder 130 can be received. The rotating shaft receiving portion 154 has a cylindrical shape and has a larger diameter than the diameter of the rotating shaft 121 so that the rotating shaft 121 of the torque motor 120 can rotate.

A donor gunpowder is mounted on one end of the bulkhead igniter 150 and the acceptor gunpowder 152 is separated from the donor gunpowder 151 by a predetermined distance and separated from each other by the partition walls, Respectively. The ignition of the transfer gunpowder 153 can be made after the acceptor gunpowder 152 has been aroused.

The donor gunpowder 151 and the acceptor gunpowder 152 may be made of CH-6 (RDX mixture), and the transfer agent 153 may be made of BKNO ₃ . The donor gunpowder 151 may be installed at a plurality of locations in the interior of the bulkhead igniter 150 so as to correspond to the electric aeration pipe 131.

In addition, an acceptor gunpowder 152 made of CH ₆ may be installed on the front surface of the transfer gunpowder 153. The acceptor powder 152 receives the shock wave due to the ignition of the donor powder 151 and induces the ignition of the transfer powder 153. The transfer gunpowder 153 may be installed at a plurality of locations in the interior of the bulkhead igniter 150 so as to correspond to the donor gunpowder 151 so that shock waves due to the ignition of the donor gunpowder 151 are transmitted.

7, the donor gunpowder 151, the acceptor gunpowder 152, and the transfer gunpowder 153 may be arranged in a line in the inside of the bulkhead igniter 150. As shown in FIG. In addition, the donor powder 151, the acceptor powder 152, and the transfer powder 153 may each be composed of a plurality of, and the electric aeration tube 131 installed in the explosion holder 130 may include a central portion 154, Two donor gunpowder 151, acceptor gunpowder 152, and transfer gunpowder 153 may correspond to two, respectively.

When the ignition signal is applied to the ignition safety circuit board 140, the igniter tube holder 130 is rotated by a predetermined angle through the rotation of the torque motor 120, The shock wave due to the ignition of the donor gunpowder 151 is transmitted to the transfer gun 153 through the partition wall and is worn to transfer the final output pressure to the igniter.

That is, unlike the conventional invention, the present invention does not have an ignition output powder separately, and has a structure capable of igniting the propulsion engine through the ignition via the transfer powder 153. That is, the transfer gunpowder 153 replaces the role of the ignition output gunpowder to reduce the ignition step, and the transfer gunpowder 153 is used as the final gunpowder. If the ignition output gunpowder is removed, the ignition delay time can be reduced because a space for mounting the ignition output gunpower can be secured. In addition, the size of the ignition safety device 100 can be downsized, and the overall gunpowder amount can be reduced, thereby ensuring structural stability.

The bulkhead igniter 150 is provided with a notch at one end thereof and has a cover portion 155 for limiting the external exposure of the transfer agent 153. Since the explosive is sealed by the lid part 155, the energy can be effectively transmitted to the outside when the explosion is not exposed to the outside air.

An FPCB (Flexible Printed Circuit Board) 123 is provided on the outer circumferential surface of the detonating tube holder 130 to transmit a current for ignition to the electric detonating tube 131. The FPCB 123 has a flexible characteristic.

Also, a separate auxiliary PCB (not shown) is provided separately on the outer circumferential surface of the detonator holder 130 so as to be spaced apart from the PCB, and can transmit a signal to the detonator pipe 131 for evacuation.

Here, the auxiliary PCB is positioned so as to overlap with the FPCB to prevent the connection portion between the FPCB and the detonating tube holder from being damaged. Since the auxiliary PCB has high strength, it plays a role of physically reinforcing the FPCB. Accordingly, it is possible to increase the reliability of the operation so that a plurality of the plurality of the electric aeration pipes 131 located in the explosion pipe holder 130 are all ignited.

 When an ignition signal is applied in the loaded state, electric current is applied to the electric aeration pipe 131 through each PCB.

In the present invention, the electric wake-up pipe 131 is double-structured. In reality, even if the wake-up signal is simultaneously applied, the current applied to each of the electric wake-up pipes 131 is accompanied by a time difference of several tens to several hundreds of microseconds . When one of the electric fire extinguishers 131 is first fired, the FPCB connected to the other one of the electric fire extinguishers 131 which are not fired can be damaged due to the shock, and current may not be transmitted for the fire. Thus, the auxiliary PCB is separately fixed to the outer circumferential surface of the holder 130, so that even if one of the electrical wake-up pipes 131 is first worn, the remaining electrical wake up tube 131, which is not worn, .

Hereinafter, the operation of the ignition safety device 100 will be described.

The ignition safety device 100 may be in any one of a safe state, a loaded state, and an ignited state.

The ignition safety circuit board 140 installed in the housing 110 rotates the torque motor 120 according to the state of the ignition safety circuit board 140, It is possible to adjust the mutual position of the electrical ignition tube 131 and the barrier wall igniter 150.

FIG. 8 is a perspective view showing a state in which the ignition safety device 100 is in a safe state, and FIG. 9 is a view showing the positional relationship between the explosion pipe holder 130 and the bulkhead igniter 150 when the safety device is in a safe state.

8, the safety state is a state in which the electric ignition pipe 131 of the explosion pipe holder 130 and the donor powder 151 of the baffle wall igniter 150 are not aligned with each other, ) And the donor gun 151 are not aligned and become obstructed by the internal partitions of the barrier wall igniter 150. The internal partition wall of the baffle igniter 150 may be made of metal. As shown in FIG. 9, in the safe state, the gunpowder of the bulkhead igniter 150 and the electric detonating pipe 131 are not aligned at 60 degrees in the circumferential direction.

FIG. 10 is a perspective view showing a state where the ignition safety device 100 is in a loaded state, and FIG. 11 is a diagram showing a positional relationship between the explosion-proof holder 130 and the bulkhead igniter 150 in a loaded state.

The loaded state means a state in which an electric signal can be received from the outside so as to enable the explosion of the baffle igniter 150.

When DC power is applied to the torque motor 120 through the ignition safety circuit board 140 of the ignition safety apparatus 100, the torque motor 120 is rotated by a predetermined angle, The tube holder 130 rotates by this angle so that the electric aeration tube 131 can align with the baffle igniter 150. As shown in FIG. 10, when the electric igniter 131 and the donor gun igniters 151 of the barrier wall igniter 150 are aligned in a line, the explosive power is applied to the gun igniter 150, The ignition safety circuit board 140 is installed inside the housing 110 so as to be adjacent to the torque motor 120 and receives an electric signal according to the loading state or an electrical signal corresponding to the ignition state from the outside And serves to generate a torque in the torque motor 120. [

The ignition safety circuit board 140 is provided with a logic circuit for normally operating the safety device only when the charging signal and the ignition signal are sequentially applied with a time difference, and the electric switching function can be performed through the MOSFET.

A sensor for detecting the rotation of the torque motor 120 is installed on one side of the ignition safety circuit board 140 to sense the rotation of the torque motor 120 and to detect the rotation of the ignition safety circuit board 140 Lt; / RTI >

The electric ignition tube 131 is configured to be connected to the torque motor 120. In the safety state, as shown in Figs. 8 and 9, the electric ignition tube 131 is not aligned with the gunpowder 150 at 60 degrees in the circumferential direction. 10 and 11, when the charging power source is applied to the torque motor 120 within several tens of msec, the ignition safety device 100 is switched to the charging state and the electrical ignition tube 131 and the explosive- Is aligned and becomes ready for exploitation. This is referred to as the loading state of the ignition safety apparatus 100. A tension spring (not shown) is built in the rotary shaft 121 of the torque motor 120 to return to a safe state when the power is shut off.

Specifically, when a signal for a charging state is applied to the ignition safety apparatus 100, when a constant charging power of approximately 20 to 30 volts (Vdm) is applied to the torque motor 120 through the ignition safety circuit board 140, The torque motor 120 rotates by 60 degrees so that the electric aeration pipe 131 and the barrier wall igniter 150 can be aligned in parallel.

When a constant ignition power source is applied to the electric ignition tube 131 after the ignition safety device 100 is placed in a charged state, the donor gun powder 151 installed in the bulkhead igniter 150 is ignited, Is transferred to the acceptor gun and the transfer gun 153 is atomized to obtain pressure for ignition of the igniter. If the ignition power source is first applied, the torque motor 120 is not operated, and therefore, the ignition source is not put in the ignition state and the explosion-proof igniter 150 is not ignited. However, if the charging power is applied again after stopping the application of the ignition power source, the torque motor 120 can be operated normally. That is, the ignition safety device 100 according to the present invention has an advantage that stability can be ensured because the ignition safety device 100 can be operated only when the charging signal and the ignition signal are sequentially applied with a time difference.

The present invention is not limited to the above-described embodiments, and various modifications and variations of the present invention may be made without departing from the scope of the present invention as defined by the appended claims.
