29 -- T-56 ENGINE GEARBOX FUZZ SUPPRESSORS SOL N68335-98-R-0209 POC Marybeth Kacek -- (732) 323-2061 The Naval Air Warfare Center Aircraft Division Lakehurst intends to procure through full and open competition, 171 each Fuzz Suppression magnetic Chip Detector Systems with an option quantity for an additional 75 each for the T-56 Engine utilized in P-3, E-3 and C-2 Aircraft. These aircraft have cockpit indicating magnetic ship detectors to monitor power section and reduction gearbox oil system debris. A warning light in the cockpit indicates debris accumulated on the chip detector and requires in-flight shutdown of the affected T-56 engine. Post-flight inspections of the magnetic plugs frequently reveal only small insignificant particles and hairlike slivers commonly known as fuzz. While chip warning lights provide increased flight safety, they also result in unnecessary engine in-flight shutdowns. The Fuzz Suppression Magnetic Chip Detector System was developed to eliminate nuisance chip lights. It automatically senses and burns away small insignificant fuzz by means of an impulse of electrical charge prior to any chip warning light illumination. The system differentiates between metallic fuzz and larger chips generated in gearbox failures. Failure to burn away a larger predetermined size chip will activate the in-cockpit chip detector light and result in engine shutdown. The proposed system shall require no airframe or engine modifications. The proposed system shall electrically connect to the existing electrical harness and receive power from the aircraft to activate and recharge the system with as little at 8 volts DC. The aircraft electrical system shall not be degraded in any way by the Fuzz Suppression Magnetic Chip Detector System. The proposed system shall have demonstrated 6000 flight hours on the T-56 Engine and meet environmental qualification tests referred to in MIL-STD-810E and Electromagnetic Interference (EMI) tests as referred to in MIL-STD-461C. The proposed system weight shall not exceed two pounds. The closing date for this Request for Proposal is expected to be on or about 9 July 1998. Request copies in writing or by telephone at (732) 323-2060. (0142)
