Connector Retention Unit (CRU)

The Connector Retention Unit (CRU) has been designed to actively adjust and retain the electrical umbilical interconnect during loading and release.

The system is designed to accept any MIL-C-38999 Series III connector system including the interconnects called up in MIL-STD-1760.

The system ensures that the vertical store interconnect height is adjusted so that as the store is released it provides a direct pull force instantly. This resolves the problem of the large shell size interconnects used in MIL-STD-1760 interfaces binding together. The threshold for this effect is if the store interconnects exceeds 15 degrees from the vertical. This can be easily achieved if using a standard fixed strong point and a single connector lanyard length.
