ERU (Ejector Release Unit)  119

ERU (Ejector Release Unit) No 119 Mk 4.


Ejector Release Units (ERU) are installed in aircraft pylons and are used for the carriage and release of external stores such as bombs and fuel tanks.

Each ERU can be fitted with explosive cartridges which are electrically initiated when commanded by the pilot. Initiation results in an expansion of explosive gases which unlock the ERU jaws (releasing the store) and extend a pair of pistons (pushing the store clear of the aircraft).
