Title: In-Line Electro-Sieve Oil Debris Analyzer
Agency: DOD
Contract: W911W6-11-C-0051
Award Amount: $359,172.00


To address the Army need for nonmetallic/metallic oil debris-monitoring sensors for use on rotorcraft transmissions and turboshaft engines, Physical Optics Corporation (POC) proposes to complete the development of a new in line Electro-Sieve Oil Debris Analyzer (ESODA). ESODA is based on an innovative sensor concept using dielectric properties to reliably identify the debris material. In Phase I POC designed and developed a laboratory prototype, which was used for ESODA feasibility demonstration. The major achievement is demonstration that ESODA interdigital capacitance (IDC) sensors can detect and discriminate ceramic particles in oil flow from metal particles and air bubbles. In Phase II POC will optimize the ESODA prototype with emphasis on its compatibility with the health and usage monitoring system (HUMS) through analysis of HUMS interface requirements, particularly ARINC 429. We will establish cooperation with General Electric, the developer of the avionics HUMS. These Phase II efforts will culminate in a full-scale ESODA prototype for comprehensive testing and demonstration in a rig test. The ESODA GUI prototype developed in Phase I will be upgraded in Phase II in accordance with Army requirements for user-friendly data analysis and diagnostics of bearing health.
