Ro-5 igniter


- metal, mechanical, pressure, instant action. Used only to adjust tank metal mines PT Mi-K.


TTU:
- weight of the igniter ..........0,34 kg
-diameter of the igniter body ........46 mm
- length of the igniter ..............80 mm
- activation force ............1 300 - 1 600 N



The Ro-5 igniter consists of a body, a sleeve, a locking screw, a firing pin, a safety pin, a shear pin, a firing pin spring and a threaded insert. The closing screw is made of bakelite, the other parts are steel. The integral part of the Ro-5 primer is a 125 g action cartridge made of pressed tritol and 2 primer primers. The firing pin is secured with a safety pin for transport.


The operation of the fuze is accomplished by pressing the protruding firing pin head with a force of 1300-1600 N, cutting the shear pin and thus releasing the firing pin, which is thrown by the firing pin spring onto the upper detonator and causing it to explode. The detonation of the fuze gradually causes the action charge and the blasting charge in the mine body to explode.


Ro-5 fuzes are packaged in special boxes of 20 together with four Ro-3, 20 transport fuses and 1 decontaminator.


When transporting, storing and handling the detonators, they must be handled with great care, as just dropping the detonator from a height of l m onto its protruding head can cause it to activate.



Practice igniter Cv Ro-5


The Cv Ro-5 practice igniter is a mechanical, pressure igniter with instantaneous action. It is used to adjust the Cv TP Mi-K training anti-tank metal mine. Use for other purposes is prohibited.


It differs from the sharp Ro-5 only in that it has 3 smoke channels closed by caps on the upper surface and a white intermediate ring around the perimeter marked Cv Ro-5.


The practice igniter consists of a body with 3 smoke channels on the upper surface closed by lacquered paper caps. The firing pin is held in the striking position by a spring in the body of the fuze by a shear pin. Above the shear pin is the firing pin which is secured by a safety pin. A firing pin is located below the firing pin. At the bottom of the firing pin is a threaded insert with a rosette. In the primer housing, instead of a sharp firing pin, there is a smoke insert through the centre of which the firing pin passes.


The igniter is activated by pushing on the protruding firing pin head with a force of l300 - 1600 N , cutting the shear pin, thus releasing the firing pin, which is thrown by the firing pin spring onto the primer. The match gradually ignites the primer on the flue liner, the stem and the flue itself. As the smoke component burns, a thick orange smoke develops which knocks out the paper caps in the body of the igniter and escapes through a smoke channel formed in the camouflage layer of earth to the ground surface. The intense smoking lasts for about 15 s and the smoke is visible at a distance of about 1 km.

The adjustment and de-adjustment of the trainer Ro-5 is the same as that of the live Ro-5. Practice anti-tank metal mines adjusted by Cv Ro-5 must not be lifted immediately after the smoke burns out in the fuse, because in 30-60 s after the smoke burns out, the lower fuse of the fuse explodes within l0 min., knocking out the breech bolt, which can cause injury mainly to the eyes.


Practice fuzes are packaged the same as Ro-5 live fuzes, in special boxes of 20 together with four Ro-3 with 20 transport fuses with 1 arrester. These fuzes are transported and stored as combustibles i.e. separately from explosives and initiators
