Abstract: Disclosed is a rifle grenade using a bullet trap. A propellent assembly is formed with a first housing configured to house a trapping unit that traps a bullet shot from a gun to travel from rear to front and absorbs kinetic energy of the bullet, and a second housing configured to house a propelling unit that is disposed in front of the first housing, and is activated by the kinetic energy of the bullet which is absorbed into the trapping unit to provide a propelling force in a trajectory direction of the rifle grenade.

Abstract: The present invention relates to an apparatus for measuring a muzzle velocity of a fired bullet so that the bullet may explode at an accurate location. The muzzle velocity measuring apparatus includes a detector configured to comprise a pair of cores encircled by probe wound coils and installed in two separate positions in an adapter, and to output a muzzle velocity signal based on eddy current signals which are generated by the probe wound coils when a bullet fired from a bullet chamber passes through the adapter, a muzzle velocity calculator configured to calculate a flight speed of the fired bullet based on the muzzle velocity signal; and a transmitter configured to transmit the calculated flight speed to the bullet.
