ZEROING OF 84 MM RL

 

ZEROING OF 84 MM RL

Gen

1.      84 mm RL ka agar round ek bar tank par miss ho jaye to ek jagruk tank apko dusri bar us par fire karne ka mauqa nahi dega. Isliye zaruri hai kih iski durust zeroing kari jae.

Zeroing ke Mauqe

2.      Hu-ba-hu anya hathiyaron ki tarah.

Zeroing ka Saman

3.      Launcher ko zero karne ke liye chand ek saman ki zarurat parti hai jo kih launcher ke saath hi hote hain  :-

(a)    Boresight.

(b)    Screw driver.

(c)     Launcher rest.

(d)    RL zeroing tgt.

(e)    Sight bag.

(f)     Bag  No 1 aur 2.

Boresight

4.      Launcher ke saath bag No1 mein ek boresight attachment hota hai jis ke do hisse hote hain, front aur rear boresight :-

(a)    Front Boresight.           Yeh 84 mm RL ke vyas ke khas tarah ka tukra hota hai jiske andar do tikon bane hain. Isko fit karte waqt iska bara katao upar ki taraf hona chahiye aur samtal line zamin ke samananter ho. Yeh muzzle ke taraf fit kiya jata hai.

(b)    Rear Sight.    Rear bore sight mein ek aperture hota hai. Yeh venturi ko khol kar  breech mein fit kiya jata hai. In dono boresighton ke madad se RL ka boresighting kiya jata hai.

Telescopic Sight Zero Karna

5.      Telescopic sight ko zero karne ke liye karawai is prakar karen :-          

(a)    Boresight fit karne ke baad launcher ko rest par rakhen.

(b)    Telescopic sight ko lagaen aur range drum zero par karen.

(c)     Elevation drum par temperature correction ko zero par lagaen.(Normal par)

(d)    Elevation aur deflection drum ke screw ko dhila karen.

(e)    Launcher ke pichhe venturi ke beech se dekhen aur 300m se ziada range par chune hue nishan par boresight ke zariye shist len. Shist milne par stand ko fix kar dein.

(f)     Ab telescopic sight ke zariye dekhen aur check karen kih donon point of aim milte hain. Yani chune hue nishan par telescopic sight mein khari aur pare line ke cross point of aim par milte hain. Agar yeh thik hai to donon locking screw ko kas dein.

(g)    Agar shist thik nahin hai to elevation aur deflection drum ko tab tak harkat den jab tak durust shist na mile. Thik shist milne par locking screw ko kas dein.

 

Open Sight ko Zero Karna

6.      Iski tartib is prakar hai :-

(a)    Telescopic sight ko utaren.

(b)    Open sight ko normal temperature ke liye zero karen.

(c)     Boresight ke beech se durust shist lein.

(d)    Open sight se shist lein aur upar / niche ki galti, range drum ko ghumate hue dur karen.

(e)    Daen / baen ki galti ke liye back sight aperture screw ko dhila karen aur aperture ko daen / baen ko harkat dein. Jab durust shist mil jati hai to screw ko kas dein aur dubara shist check karen.

(f)     Durust zero ho jane ke bad temperature locking screw ko dhila karen aur temperature ke lihaz se manzurshuda nishan ko zero ke samne laga den.

Zeroing 9mm Sub Calibre Adapter

7.      Agar Sub Calibre Adapter aur launcher ke axis of barrel ek sidh mein ho to, durust range lagakar jab HEAT round fire kiya jae to donon  ke round yani ki launcher aur sub calibre adapter ek hi jagah lagenge.

(a)    Zeroing se Pahle.  Isse pahle launcher ko durust zero kiya hua hona chahiye.

(b)    MPI.          Zeroing ka target 300m par agar laga ho to MPI point of aim par banti hai 100-250m tak  zero karte waqt MPI point of aim se 10 cm niche banega. 350m se 20 cm niche aur 400m se 50 cm niche.

(c)     Tariqa.      Zero karne ke liye 9mm tracer round ka paanch round ka ek group fire karen. Agar MPI point of aim par banti hai to sub calibre durust zero hain. Nahin to karwai is prakar karen :-

(i)      Upar / Niche ki galti.        Elevation locking screw dhila karen aur barrel ko elevation screw ke madad se upar niche ki harkat dein. MPI neeche bani ho to barrel ko upar karen aur upar ho to neeche karen. Locking screw kas dein.

(ii)     Daen / Baen ki galti.        Deflection screw ki madad se daen ya baen harkat dein. MPI agar baen le jani ho to barrel ko baen karen aur agar daen le jani ho to daen karein.

(d)    Asar.        Zeroing screw ko ek pura chakkar dene se 300m par MPI 108 cm sarak jaegi aur 100 m par 36cm ka faraq parega.

(e)    Paanch round ka ek group fire karke dubara check karein.
