70 -- EMERGENCY POWER RESERVE & ENGINE MONITORING SYSTEM SOL N00421-96-R-5152 DUE 073196 POC David H. Hess, Contract Specialist, (301) 342-3310 ext 14 Linda Suggs, Contracting Officer, (301) 342-3310 ext 11. The Maritime, Aeromechanical, & Flight Controls (4.11.1.3) competency of the Naval Air Warfare Center Aircraft Division, Patuxent River, MD, has a requirement for an Emergency Power Reserve and Engine Monitoring System (EPR/EMS) for the ES-3A/S-3B/TF34 platform including all derivatives. The EMS shall be capable of monitoring and recording as a minimum, the following parameters, both left and right, relative to time: engine fan speed; engine core speed; engine fan inlet and inter-turbine temperatures; engine fuel flow; engine oil pressure; vibrational frequencies and magnitude emitted from the fan, compressor and turbine; power level angle; aircraft airspeed, altitude, and heading; and, outside air temperature. The ability to record discrete events such as engine start, takeoff, landing, and end-of-flight information, and to calculate engine performance is also required. The system must be able to identify, annotate, and provide diagnostic information for all engine operational exceedances. The EMS must also be capable of monitoring and comparing performance parameters (i.e., fan speed, interturbine temperature, power lever angle, weight on wheels switch position) for both engines and upon detection of thrust degradation in either engine, the system must have the capability to disable the interturbine (T5) control amplifier in one or both engines. The capability for the flight crew to record, at random, engine operating data must be included in the system. Preliminary design concept is oriented toward utilization of an airborne data processing/collection/control unit, of minimal size and weight (approximately 170 cu. in. X 6 lb.), capable of storing data from four 6-hour sorties. The capability to record cumulative engine fan and core speed cyclic data and interturbine temperature excursions is also required. The data must be ''readily'' retrievable by maintainance personnel and capable of being analyzed and displayed using a laptop or personal computer that will be designated as the ''ground station''. Software and hardware design should provide for expansion to include additional sensors/parameters for out year system improvement. System design must be functionally compatible with the S-3 operational environment, shipboard and shorebased. Requests for copies of the solicitation must be sent to David Hess at the address indicated in block 7 of this synopsis or faxed to (301) 342-1161. These requests must be received within 15 calendar days from the date of this notice publication. The cut-off date for receipt of proposals in response to the solicitation will be 35 days from the date of this notice publication. This item will be procured as a 100% small business set-aside with a corresponding SIC code of 3571. To be considered a small business for purposes of this procurement, the business cannot have more than 1000 employees. All responsible sources may submit a proposal which shall be considered by the agency. See Numbered Note(s): 1. (0191)
