At a firing rate of 3,000 rounds per minute, an M134D will exhaust 50 cartridge cases and links every second. The management of such a high exhaust rate poses unique challenges, and if not done correctly, can cause cases and links to become tangled and cause malfunction. As with all other aspects of the Minigun, Dillon Aero has spent a significant amount of time perfecting its link and brass exhaust solutions.
For aviation, insuring that link and brass exhaust exit the aircraft in a controlled and safe manner is necessary to avoid FOD hazards to aircraft rotor systems and skin. For land and maritime installations, directing the flow of brass away from operators prevents contamination of the vehicle. In certain cases, the addition of a dump tube may be desirable to channel the flow of link and brass even further.
