תיאור
A massive steel mortar enclosed by a projectile is suspended from the pendulum axis by a long pendulum arm.
The explosive charge of a given mass is initiated in the mortar cavity.
Due to the explosion of the detonative sample, the projectile is fired out of the mortar, whereas the mortar is swung backwards from its position by the counteracting force.
The maximum swing of the mortar is recorded and it serves as a measure of the explosive power.
The device consists of a ballistic pendulum, a steel projectile and basic accessories for chargé preparation. Mass of the sample is in the range of 2 – 10 g TNT eq.
