A -- THERMOCHEMICAL AND THERMOPHYSICAL PROPERTIES OF FLUIDS, LUBRICANTS AND RELATED MATERIALS SOL F33615-95-R-5027 DUE 061395 POC Lt John Van Huffel, Contract Manager, WL/MLKN, (513) 255-5051; Frederick D. Rueth, Contracting Officer, WL/MLKN, (513) 255-5051. Wright Laboratory is soliciting proposals for the research effort described below. This solicitation and resulting award shall be made in accordance with the Research and Development Streamlined Contracting Procedures (RDSCP) described in DFARS 235.70. This is the solicitation, there will be no formal RFP or RFQ. The name, address and telephone number of the representative of the contracting officer for this solicitation is shown as POC above. This solicitation consists of this notice, any subsequent amendments, and a supplemental package which is available by writing to the above address. Offerors who did not respond to synopsis MLK-95-02 published 94AUG17 should provide, in writing, their complete address information to Wright Laboratory (see above address) in order to receive the supplemental package and any subsequent amendments(if applicable). All of the mandatory terms, clauses and provisions at DFARS 235.7006, Research and Development Streamlined Contracting format, and the following optional items are incorporated by reference: B.3, B.6, C.2, E.3, E.4, F.1, G.2, H.3, i.42, I.43, I.44, I.53, I.66, I.68, I.70, I.74, I.76, I.85, I.87, i.88, I.89, I.94, I.97, I.100, I.107, I.108, I.127, I.129, I.144, i.153, I.154, I.156, I.162, I.164, I.165, I.167, L.14, M.2. This solicitation includes clauses and provisions from FAR 1990 edition updated through FAC 90-25 and DFARS 1991 edition updated through DAC 91-6. The standard evaluation factors found in Section M of DFARS 235.7006 apply. A Cost Plus Fixed Fee (Completion) type contract is contemplated. The estimated period of performance is 53 months commencing on or about 95JUL17 which includes 5 months for writing and reviewing the final report. It is expected that this contract will be awarded based upon a determination that there is adequate price competition, therefore, the offeror is not required to submit or certify cost or pricing data with its proposal. If, after receipt of the proposals, the Contracting Officer determines that adequate price competition does not exist in accordance with FAR 15.804-3, the offeror shall provide certified cost or pricing data as required by the Contracting Officer. To be responsive to this solicitation, submit 6 copies of your Technical proposal no later than 1500 hours, 95JUN13, addressed to: Wright Laboratory, WRIGHT LABORATORY BLDG. 7, Attn: Frederick D. Rueth, WL/MLKN, 2530 C ST. AREA B, WRIGHT-PATTERSON AFB OH 45433-7607. Submit 6 copies of your Cost proposal and one copy of your Small and Small Disadvantaged Business Subcontracting Plan (if applicable) no later than 1500 hours, 95JUN27, to the same address. The page limitations for technical and cost proposals are specified in DFARS 252.235-7006 (L.24). A Contract Security Classification Specification (DD Form 254) is in the supplemental package. The DD Form 1423, Contract Data Requirements List, is included in the supplemental package. The technical requirements, including the reporting requirements, are contained in the supplemental package. The objective of this effort is to award a 53 month program for the determination of thermophysical properties of advanced Air Force functional fluids and lubricants using existing methods where available and developing new methods where needed. The research efforts of the WL Materials Directorate's Nonstructural Materials Branch produce a wide variety of base fluids, additives and formulations. The anticipated chemical class of the majority of the anticipated candidate materials is the perfluoropolyalkylethers. Their unique chemistry results in many of the existing test methods, which were originally developed to study hydrocarbon-based fluids, to be not applicable. An example of this is the four ball wear test (ASTM D2266) which usually predicts the boundary lubricating ability of candidate lubricants quite well. This test method predicts that the perfluoropolyalkylether fluids would function quite well in boundary lubrication regimes, but when attempts are made to use them in applications where the primary lubrication is the boundary lubrication regime, they are totally unacceptable. Other thermochemical and thermophysical properties include: thermal and oxidative stabilities up to 425 degree C, corrosion-oxidation stability up to 400 degree C, pressure-viscosity coefficient for pressures from 0 to 30000 psia at temperatures up to 315 degree C, isothermal secant and adiabatic tangent bulk moduli, oxygen absorption characteristics at temperatures of 160 degree C to 425 degree C, thermal conductivity, specific gravity, kinetic and absolute viscosities from -54 degree C to 400 degree C, corrosion inhibition properties, vapor pressure up to 400 degree C, pour points down to -70 degree C, lubricity up to 400 degree C, oxygen sensitivity and metal analysis. The lubricity test methods must be capable of determining wear as a function of actual time, measuring coefficient friction and fluid and metal specimen temperature. All of the techniques used to determine the properties must be capable of using as small of a volume as possible since these candidate materials will typically be available in small quantities initially. Bearing tests of candidate advanced greases will be required. Approximately one man-year of technical effort per year is required. Responses must fully describe the appropriate equipment, facilities, background and expertise of responding organizations. (0129)
