for Critical Debris Detection
Luna is developing a debris detection system that saves size and weight, and captures virtually all circulated bearing debris.
Bearings and gears within high performance aircraft and rotorcraft powertrains are subjected to significant loads that can result in premature failure of these components. Small amounts of wear debris may indicate initiation of bearing and gear failure processes. Current failure detection methods suffer from poor debris capture efficiency (i.e. magnetic chip collectors) and may require significant mechanical modifications for retrofit (i.e. particle counters).
To address the need for improved sensing techniques to detect initial stages of engine component damage, Luna is developing a debris detection system utilizing the propulsion system’s main lubricant filter as the primary sensing element. This strategy saves size and weight by employing existing fluid connections and components, and captures virtually all circulated bearing debris. The patent pending advanced oil filter monitoring system detects small levels of critical system debris and is designed for straightforward retrofit into existing aircraft and rotorcraft propulsion systems.
