Cutaway model of a Chinese 82mm Dk82 type 65 HEAT cartridge. This cartridge is a fin stabilized shaped charge anti-tank cartridge.
The nose spike, body and tail are made of pressed and machined steel parts. On top of the nose spike an anti-ricochet cap is crimped in place, of which the top rim is hardened.
The ignition charge in the tail houses 46 grams of black powder.
The main charge in the warhead is consists of 418 grams RDX and a PETN booster below the wave shaper.
The lower part of the warhead (around the fuze) houses a black plastic filler piece.
The cone is made of red copper.
Functioning of the fuze:
A : Fuze body
B : Firing pin
C : Arming piston housing
D : Locking ball
E : Arming piston
F : Arming piston spring
G : Torque spring
H : 180 degrees radial rim
On the inside of the Bakelite fuze body (A), a longitudal slot is machined, housing the locking ball (D), fixating the arming piston housing (C) from moving forward and rotation. A pin on the backside of the arming piston housing (C) also locks arming piston housing from forward movement. This pin rests on a rim (H) in the fuze body that only covers 180 degrees.
Two spring can be observed; the arming piston (F) setback spring in the arming piston housing which keeps the arming piston (E ) inside the arming piston housing in the forward position, and a torque spring (G) at the base of the arming piston housing.
Upon firing, inertia moves the arming piston (E ) backward, riding the arming piston spring (F). This allows the locking ball (D) to roll inward, allowing the torque spring to rotate the arming piston housing, and allowing the arming piston housing to move forward upon impact. The rotation of the arming piston housing (C) causes the pin on the backside of the arming piston housing to rotate in such a way that it is placed in the 180 degrees section that is not covered by the rim (H), enabeling the arming piston housing to move forward.
Weight of the cartridge : 3,3 kg
Diameter : 82mm
Length cartridge : 583 mm
V0 : 240 mtrs/sec
Penetration : 356 mm RHA
