66 -- PROPELLANT TEST SYSTEM SOL N68936-00-R-0075 DUE 051900 POC Maggie Green, Contract Specialist, (760) 939-4274, Doreen Robbins, Contracting Officer, (760) 939-9665 The Naval Air Warfare Center Weapons Division, China Lake, CA intends to enter into negotiations on an other than full and open competition basis with MTS for a propellant test system. MTS is the only company capable of providing the required system, as it must be compatible with an existing MTS DAQ and Control system with TESTSTAR II software. The software can only communicate with the servo- and pressure valves used in the MTS 810 Load Frame with chamber. The system shall consist of (1) 810 Load Unit. The unit shall include a MTS Model 318.10S 2-column Load Frame [free-standing, self-supporting unit requiring no special foundation with a nominal dynamic load rating of +/- 22000 lbs., movable crosshead, integral actuator, nominal frame stiffness of 1.5 x 10E6 lbs./in based on a crosshead position of 48.5 inches above the platen, a test space of 21 inches x 5.75 to 63.5 inches (W x H) with an overall height of 119 inches and a base dimension of 33.25 inches X 24 inches (W x H) and crosshead hydraulic lifts, locks and controls]. The unit also shall include a MTS Model 244.12 Hydraulic Actuator [with a nominal dynamic force rating of +/- 5500 lbs., a total displacement stroke of 6 inches, coaxially mounted full stroke linear variable displacement transducer for measurement and/or control, and internal threads in the piston rod for mounting a grip of load cell], and a MTS Model 661.9E-04X Load Cell [internal fatigue rate to +/-5500 lbs., an accuracy of +/- 0.5% or better, high output for the best possible resolution and precision, symmetrical output between tension and compression for accurate through-zero testing, 150% static overload capacity of rated load, pressure compensated for use in pressure vessel and internal mounting threads]. The system shall also consist of one (1) MTS 298.12 Hydraulic Service Manifold. Components from the existing MTS load frame shall be utilized. Manifold shall have the capability of close-coupled accumulators (allowing maximum high frequency response of servovalves). Off/Low/High pressure control, slow pressure turn on, and fast emergency unload for system depressurization. Also, the system shall be rated for 30gpm flow at a maximum operating pressure of 3000psi. Included in the system's package shall be one (1) MTS 252.24 Servovalve rated for 10 GPM, and has high response and 5-port mounting; one (1) MTS 506.00, 25-foot Hydraulic Hose Set [which includes two (2) 3/8-inch drain hoses, two (2) 1-inch pressure and return hoses, and fittings]. System integration of the existing MTS hardware at China Lake with new components and subsystems shall be provided by MTS, including a Single Bay Console for electronics, a System Operator Panel, Temperature and Pressure readouts, TESTSTAR rackmounting and integration, digital oscilloscope integration, interface to on-site HPS unit and system cabling. MTS shall also provide factory calibration, which includes four ranges (100%, 50%, 20%, and 10% of full scale). Calibrations shall be performed at the factory prior to shipment in accordance withMTS calibration procedures. Also included in this package, shall be one (1) MTS 632.12E-20 Axial Extensometer having a 1.00-inch gauge length with a strain range of +50% and -10%, and capable of operating within a temperature range of -150 to 300 degrees F, and a pressure range of 0 to 2000psig. This includes quick attach springs for round and flat specimens. MTS shall conduct the TESTSTAR Calibrations on the MTS 632.12E-20 Axial Extensometer for two ranges. With the extensometer, MTS shall provide one (1) TESTSTAR Extensometer cable, 30'(10m). As for the MTS propellant test pressure vessel, it must be/have: (a) able to condition between a temperature range of -70 to 200 degrees F, and pressurize from 0 to 2000 psig, (b) minimum internal diameter of 200 mm (7.9 inches), (c) made of stainless steel construction, certified with an ASME stamp, (d) a rupture disk safety system, (e) of an interlocked breach-lock enclosure design, (f)a 2-inch diameter observation window and a 1-inch diameter window for an external light source, (g) able to utilize existing supplied liquid nitrogen for cooling and dry nitrogen for pressurization, (h) an internal load reaction from designed to accommodate a 6-inch JANNAF rail specimen. MTS shall also provide one (1) MTS vessel temperature and pressure control system. Chamber and control system shall be integrated to new load unit. Delivery shall be 4 months after award of contract. Requests for this solicitation may be requested from Maggie Green at (760)939-4274 or FAX (760)939-4241. All responsible sources may submit a proposal which shall be considered by the agency. Responses to this intent to solicit, other than MTS, must be submitted in accordance with Note 22. See Numbered Notes: 22 & 26 Posted 04/18/00 (W-SN446152). (0109)
