Description

Propaganda shell

Technical field:

The utility model is a kind of enemy of air-drop, can carry out the device of broadcast publicity to the enemy, is applicable to the extraordinary demand that proceeds to certain phase in war.

Technical background:

When in war, carrying out psychological war, need carry out broadcast publicity to the enemy, as broadcasting war progress situation, the war meaning, our policy, international situation and playing back music etc. in order to disintegrate enemy's soldiers' morale, play the effect that weapon does not have.

Summary of the invention:

The utility model purpose is to disclose a kind of propaganda shell.Be to utilize airplane air dropping to arrive the sky, enemy's control district, when dropping to apart from ground certain altitude or certain hour, interior arrangement is opened automatically, and beginning is carried out broadcast publicity from the trend enemy.

The utility model profile such as same piece of GP bomb, the streamlined body that constitutes by bullet and bomb body and form exploding shell by the projectile tail of a plurality of fin blades 10, playing feature is: be equipped with in the body, the built-in shock-absorbing spring 2 of bullet, this spring housing is at a rifled tube 1 that is welded on the bullet cover, rifled tube 1 lower end withstands on the bullet cover inwall, and the other end heads on the power supply fixed head, is connected on the rifled tube by power supply fixed head center pit with a bolt 3.Accumulator 4, power amplifier 5, controller 6 and loudspeaker 8 are housed in the bomb body, and all have a plurality of diffusing sound holes 7 around the housing, lower end power supply fixed head is equipped with two accumulators 4, for controller 6 and power amplifier 5 power supplys, controller 6 is to produce a pressure reduction by pressure transducer, be converted to electric signal, through amplifying and time-delay conducting control MP3 and power amplifier power supply.The parachute storehouse is arranged in the projectile tail, the least significant end of bullet is a fixedly umbrella ring 9 of a ring lock, fixedly in the middle of the umbrella ring 9 groove is arranged, main chute is equipped with in the parachute storehouse, after main chute is packed the umbrella storehouse into, and the extractor parachute of packing into, adorn a coil component spring wire loop 11 on the extractor parachute tail-hood, respectively there is circular hole at its two ends, and in the groove, the other end dispensed device with carrier aircraft and links to each other in the middle of spring steel wire was fixed on ring lock 12 set collars.

Description of drawings

Fig. 1 is the utility model structural representation;

Embodiment:

The utility model profile such as same piece of GP bomb; as Fig. 1,, can be made into large-scale or small-sized as required so claim propaganda shell; large-scale broadcasting power can reach more than 100 watts; by the plug-in input of carrier aircraft, small-sized broadcasting power can dispense device by carrier aircraft and throw in below 100 watts; body structure can be divided into three parts; bullet, bomb body and projectile tail, bullet play protection and damping effect.The built-in shock-absorbing spring of bullet, this spring housing is at a M8 rifled tube 20 that is welded on the bullet cover, and the lower end withstands on the bullet cover inwall, and the upper end heads on the power supply fixed head, be connected on the rifled tube by power supply fixed head center pit with a bolt, adjust 20 elastic space.Bomb body partly is equipped with accumulator, power amplifier, controller and loudspeaker, and on housing, have 16 20MM sound hole that looses, lower end power supply fixed head is except that with the bullet rifled tube is connected, two accumulators also are installed, use for controller and power amplifier a-b power pack, the battery long service life, once charging can be used tens hours, the principle of work of controller is: when carrier flies certain altitude, because the variation of air pressure makes pressure transducer produce a pressure reduction, and this pressure reduction is converted to electric signal, through processing and amplifying, remove to control a chronotron, this chronotron can be set time delay in advance on request, when reaching time delay, circuit turn-on, control MP3 and power amplifier power supply connection work.Power amplifier adopts TDA to debug, and used loudspeaker are the high-fidelity loudspeaker, to reach undistorted and long-distance transmissions.Projectile tail had both played the body equilibrium activity, was again the parachute storehouse.Keep stable landing when dispensing device for body is left, 4 fin blades are equipped with in projectile tail portion.The least significant end of bullet is a ring lock set collar, one groove is arranged in the middle of the set collar, after main chute is packed the umbrella storehouse into, the extractor parachute of packing into, adorn a coil component spring wire loop on the extractor parachute tail-hood, respectively there is circular hole at its two ends, will play rustic fixation with steel wire on the ring lock set collar in the middle of in the groove, the other end dispenses device with carrier aircraft and links to each other.When bullet is cast in dispensing device, promptly be disengaged insurance, spring steel wire coil opens, and relies on the wind-force extractor parachute to be pulled out, and drives main chute and opens.

Claims
