[Prior art]
Conventional flying device with combustible medicine package has been devised to eliminate the residue after burning of combustible medicine package part due to the characteristics of the flying device, but signal lines etc. necessary for timed function remain. It was difficult to provide such a detonation mechanism with a timed function, because it would cause a problem. Further, direct contact of the signal wire with the explosive may cause unintended ignition of the explosive due to heat generation or spark when power is supplied to the detonating mechanism, which is difficult in terms of safety.

[0029]
FIG. 6 is an electric signal transmission block diagram of the explosion mechanism 16 with a time limit function incorporated in the flammable medicine packaged flying object device 10 having the above-described configuration. As can be understood from the drawing, one end of each of the three types of first to third signal lines 21a to 21c is connected to the explosion mechanism 16 with a time limit function via a second signal line connector 22 which is a rotary connector. The other end of each of the signal lines 21 a to 21 c is connected to the end of the wing 15 and the first signal line connector 19 fixed to the cylindrical connecting member 40 for the third signal line of the metal medicine package bottom 32.

[0030]
The first to third signal lines 21 a to 21 c are respectively connected to ring-shaped electrodes 36 to 38 formed on the outer surface of the metal medicine package bottom 32 via the third signal line connector 39. As described above, when the tail plug device 52 is closed, the electrodes 36 to 38 come into contact with the tail plug device side signal line electrodes 54 to 56, and various data are transmitted to an external data input device (not shown). To the detonation mechanism 16 with a timed function via the first to third signal lines 21a to 21c.
[0031]
The first signal line 21a is used for transmitting a time data signal, the second signal line 21b is used for charging, and the third signal line 21c is used for a common ground of 21a and 21b.
[0032]
FIG. 7 shows an electric circuit block diagram of the explosion mechanism 16 with the timed function applied to the present invention, and FIG. 8 shows an operation flow of the explosion mechanism 16. The electric circuit includes a collision detection circuit section A and a timed circuit section B.
The collision detection circuit section A includes a piezo generator A1 dedicated to collision detection, which generates power in response to a shot impact of a shell. The electric power generated in the piezo generator A1 is charged in the collision detection operation power supply capacitor A2.
[0033]
The power supply capacitor A2 for collision detection operation is charged, and when this charged voltage reaches a predetermined value, a trigger signal is sent to the timer circuit B6. The timer circuit B6 starts timing using this signal as a trigger signal, and at the same time, the ignition capacitor A3 for the main flying head starts to be charged by the current from the power supply capacitor A2. The stored firing capacitor A3 for the main vehicle head enables the blast circuit A4 for the main vehicle head to operate, and the blast circuit for the vehicle head receives a blast signal from the collision plug-out device 13 when the blast signal is received. For the first time, the main body head detonator A5 is activated to explode the flying body part 11.
[0034]
On the other hand, in the timed circuit section B, a time data signal is input from the outside to the data input / output I / F circuit B1 in the timed circuit section B via the tail plug device 52, and the timed data signal in the timed circuit section B is also input. A required amount of electric power is supplied to the wire capacitor B2 for the timed circuit. The power discharged from the time-limit circuit power supply capacitor B2 operates the constant voltage circuit B4. The constant voltage power output from the constant voltage circuit B4 activates each circuit in the timed circuit section B.
[0035]
The second data input to the data input / output I / F circuit B1 is stored in a data storage circuit B3. The output from the constant voltage circuit B4 activates the reference clock generation circuit B5 and the clock circuit B6. The timer circuit B6 waits for a trigger signal to be sent from the power supply capacitor A2 for collision detection operation in the collision detection circuit unit A as described above, and starts time measurement. A signal is output to the blasting circuit A4 for the head of the main body of the collision detection circuit A via the safety mechanism B8 in association with the data signal from the data storage circuit B3. The primer A5 is activated and blasts.
[0036]
The safety mechanism B8 receives a signal from the determination circuit B7 and also receives a signal from the S & A (safety device) installed in the detonation mechanism 16 that the flying head can be blasted. Even if the signal of the blast OK is received from the determination circuit B7, when the signal indicating that the flying head cannot be blasted is received from the S & A, the signal from the determination circuit B7 is blocked, and the main flying head described above is blocked. A blast signal is not sent to the part blasting circuit A4 to prevent unnecessary explosion.
[0037]
Also, should the landing occur before the measurement time elapses, the collision detection device 13 installed at the tip of the flying head 11 is activated, and the main flying head of the collision detection circuit unit A is operated. A signal is sent to the part blasting circuit A4, and the blasting is performed via the main flying head detonator A5.
[0038]
Now, after the projectile device 10 with a combustible medicine package having the above-described configuration is loaded into the explosive chamber 51 of the acceleration tube 50, the tail plug device 52 is closed. Here, first, power is supplied from a power supply (not shown) provided outside to the power supply capacitor B2 for the timed circuit via the second signal line 21b, and then the constant voltage circuit is driven to operate the timed circuit section B. Let it start.
[0039]
Next, while measuring the distance to the target, the flight time of the flying body unit 11 to the target is calculated, and the measurement data signal and other necessary data signals are transmitted to the first input device (not shown) from an external input device (not shown). The signal is sent to the detonation mechanism 16 with a time limit function via the signal line 21a, and stored in the detonation mechanism 16.
[0040]
When preparation for firing such as power supply and transmission of data is completed, the firing pin 53 is operated to ignite the explosive via the electric ignition device 34, leaving the metal medicine package bottom 32 of the combustible medicine package 30. The medicine package body 31 burns, and the flying body 11 is fired.
[0041]
Simultaneously with the launch of the flying body portion 11, the piezo generator A1 provided in the collision detection circuit portion A receives the pressure at the time of firing and generates power, and the electric power is supplied to the collision detection operation power supply capacitor A2. The current is supplied from the supplied power supply capacitor A2 for collision detection operation, and the charged current is sent to the ignition capacitor A3 for the main flying head of the collision detection circuit unit A as described above. A trigger signal is sent to charge the ignition capacitor A3 for the main flying object head, and at the same time, the timer circuit B6 is activated to start timing.
[0042]
In this manner, when the explosive device 16 is loaded in the explosive chamber 51 and the tail plug device 52 is closed, the power supply and measurement data are supplied to the detonation mechanism 16 having the timed function of the flammable medicine packaged flying object device 10. Since signals and the like can be input, it is possible to promptly input a distance measurement result and to quickly fire.
[0043]
Further, the first to third signal lines 21 a to 21 c connecting the metal medicine package bottom 32 and the detonating mechanism 16 with the time limit function are inserted into the signal line insertion holes 18 of the wing seat 14, and the rear end of the wing 15 Since the signal line 21 is connected to the first signal line connector 19 through the space provided at the center of the portion, the signal line 21 does not come into contact with the explosive, thereby preventing accidental ignition of the explosive due to heat generation or sparking, and safely. Electric power can be supplied to the detonation mechanism, and blasting is realized according to the set time when the flying object portion 11 is fired without leaving the signal line 21.
[0044]
