Luna Labs has developed a family of devices to track the health of critical US Navy fleet machinery systems such as hydraulic actuators, motors, pumps, and compressor systems.  Our embedded condition-based monitoring (eCBM) technology brings smart maintenance assessments to the surface ships and submersibles to inform maintenance needs, reduce operating costs, and maximize mission readiness.

Laboratory and field testing of Luna Labs’ eCBM units with original equipment manufacturers (OEMs) have demonstrated damage classification accuracies between 92% and 99% for hydraulic actuators and motor-driven machinery. Results have motivated follow-on shipboard testing where we are deploying eCBM devices to monitor equipment in port and at sea. The goal is to provide crew with resources that reduce time spent on manual inspections and allow more focus to be directed to mission needs.

Luna Labs began developing eCBM technologies seven years ago, funded through the US Navy and partnering with OEMs.  We conducted validation testing within the first 24 months on Navy-grade assets, and testing has evolved to warfare center laboratories and recent shipboard opportunities. Luna Labs supports the Navy Surface Warfare Centers in Philadelphia and Carderock, as well as the Office of Naval Research.  We have successfully demonstrated our technologies with Moog Flo-Tork on their next generation hydraulic actuators. These studies considered both prediction accuracy and the minimum number of cycles that must be collected to begin training reliable damage classification algorithms, a key feature when considering how the process can be deployed on shipboard applications.

The general purpose eCBM device supports 6 different sensor types, with up to 13 channels of information. The hardware can gather data over 150,000 cycles and uses ultra-low power sleep states to conserve energy with the goal of 5+ years of operation.  The devices allow predictions to be made locally, significantly reducing how much data is transmitted and stored, while conserving energy on low power battery operated devices.

The general purpose eCBM sensor node can be provided with three enclosure configurations for 1) hydraulic actuation systems, 2) motors and pumps, and 3) vacuum pump systems.  Luna Labs is also generating the compact eCBM device that reduces volume by approximately 60%. Prototypes have been fabricated and are undergoing testing.
