Ta stotka su bili BK-5M kojih je 250 komada isporuceno 1961-62 sa prvim primercima T-54A koji su stigli u ove krajeve. Najveci deo je potrosen za testove i rasturen radi kopiranja.
To su bila jedina KZ za tenkove T-54/55 do uvodjenja domaceg KZ M69 - znaci u BK ih nisu imali sve do 1969-70...
Mi smo mogli da vidimo i sta su Ameri uradili na 90mm M431 (3000 komada isporuceno 1956 nakon upada Sovjeta u Madjarsku, sa bukvalno eksperimentalne linije, sa originalnom Txxx oznakom), sa njegovim piezo upaljacem, doduse isti je imao problem pri vecim uglovima, ali kao sto rece, pionirske godine...
122 su dosli sa haubicama D-30, ne sa Gvozdikama, osim ako nesto zesce nisam pobrkao.

bojank ::I sam ima minijaturno kumulativno punjenje (vidi se u preseku), sa polukruznom oblogom. Ideja je da isa pogodi detonator koji je u dnu projektila (opet se vidi na preseku).
Tako da KZ sa istim ima dva kumulativna punjenja...
Ti detonatori sa kumulativnim/MS punjenjem su prije rata rađeni u Pobjedi u Goraždu, pa su u ratu zalihe istih korištene kao eksplozivna punjenja u PP minama Goraždankama. Kako se mina aktivirala nagazom baš na ovu eksplozivnu čauru snaga detonatora je bila dovoljna da probije stopalo i izbaci vojnika iz stroja.
Mislim da je ova mina jedan od najboljih primjera ratne manufaktuire i improvizacije u BiH.

robognus ::
Кориговање даљине са ваздушним кочницама? Занимљиво решење.
Што се тиче ове илустрације, увек се сетим стрипа ”Редов Били” кад генерал гледа совјетски анимирани филм о свемирским летовима и пита се како могу да буду испред у ракетама, а толико су лошији у анимираним филмовима.

Ideja sa kočnicama u upaljaču i nije tako nova. Francuzi su je realizovali kao SPACIDO još pre desetak godina.

Kineski MJ-1 upaljač za raketu 107 mm Type 63 i princip rada.
Citat:Functioning of the MJ-1 fuze:
The MJ-1 fuze is an impact fuze with a graze function. It also has a 0,1 second delay function, enabeling it to “dig in” the ground or a target before exploding. It exists of an upper (1) and lower (2) body. The upper body houses the centrifugal weights (3), the firing pin (4), the firing pin spring (5), the firing cap housing (6), the locking bushing (7) and the locking bushing spring (8). Upon firing, the centrifugal weights (3) are thrown outward enabeling the locking bushing (7) to move upward by means of it’s spring (8), locking the centrifugal weights (3) in their outward position. The firing pin and the firing cap housing are now both released; the firing pin can move down into the firing cap (red), the firing cap housing can move upward when in graze function. The lower fuze part (2) houses the delay screw (9), a brass screw with a centerline channel that can be opened and closed by rotating the screw on the outside of the fuze 90 degrees by means of a key. When closed, the flame of the firing cap has to pass through a brass screw (10) containg a pressed black powder pellet (11) that delays ignition for 0,1 seconds. Above the delay screw the rotation safety slider mechanism is placed. This is a disc (12) containing a slider (13) which is held in place by two spring loaded centrifugal weights (14). Upon firing the weights are thrown outward, releasing the slider (13) to move outward and open the flame channel. The disc is closed by a sheet metal cap (15). On top of the rotation safety two graze weights (16) are placed. These exist of two ring halves with a chamfered hole on the inside that fits over the chamfered edge on the lower portion af the firing cap housing. Both ring halves are lowered two mm on the wide side (see pict.05) enabeling them to move inward upon impact. Upon graze impact the weights –which in flight are thrown outward against the inner wall of the lower fuze housing- are thrown in the direction of where the outer skin of the rocket hits it target, launching the firing cap housing upward into the firing pin.
Upon impact –with either impact or graze- the flame of the firing cap wil move down, through the channel of the opened safety slider (12), through either the opened central channel of thenbrass screw (no delay), either through the delay pellet (11). The flame ignites the detonator (17) which ignites the booster charge (18), which on it’s turn ignites the main TNT charge of the rocket warhead.
Weight of the complete rocket: 19 kg.
Weight of the explosive charge: 1,3 kg TNT.
Vo: 385 mtrs/sec 1260 ft/sec.
Range: 8.050 mtrs.
The twelve rockets can be fired in seven to nine seconds.
