Line Replaceable Modules (LRM)
In recent years, a better approach toward battlefield maintenance has emerged, which utilizes Line Replaceable Modules (LRM) to speed, simplify and significantly lower the cost of system repair. At Curtiss-Wright, we're helping to drive the move toward LRM maintenance through our leadership role in bringing rugged, ESD (electro-static discharge)-protected VPX modules to the embedded COTS market.
The innovative LRM approach promises to greatly reduce the logistics burden by removing and replacing modules such as pluggable processing and I/O boards directly at the platform; this eliminates the traditional step of first removing the system-level "black box" and sending it back to a depot for the eventual replacement of a pluggable circuit board. By designing a system around the concept of LRMs, and holding spares at the LRM level instead of at the box level, the cost, volume, and weight of spares holdings can be reduced.
