Based on the existing TG480 ejection release unit, the TG482 was designed in order to eject 250lbs small diameter munitions and to ensure the specific ejection requirements of the same, i.e. :
- an ejection under high velocity that requires a high level of thrust (End Of Stroke velocity up to 8 m/s)
- the low mass/inertia of such munitions requires adding a VE wedge between the ejection pistons and the munition to avoid the yaw movement during the thrust
This device is a pneumatic ejection release unit designed to cope with high level technical and operational specifications (high release speed, for instance). It is equipped, amongst others, with pre constraint device including a torque limiter.
