A -- DEVELOP AND DEMONSTRATE AND AFFORDABLE ONLINE COMBUSTION PRESSURE DETECTION SYSTEM DUE 032400 POC Jon C. Schultz, Contract Specialist, Phone (216) 433-2764, Fax (216) 433-2480, Email Jon.C.Schultz@grc.nasa.gov WEB: Click here for the latest information about this notice, http://nais.msfc.nasa.gov/cgi-bin/EPS/bizops.cgi?gr=D&pin=22#3-143932. E-MAIL: Jon C. Schultz, Jon.C.Schultz@grc.nasa.gov. NASA/GRC plans to award a contract for affordable on-line combustion pressure detection for general aviation propulsion systems. The contract will acquire services for the development and testing of a unique temperature compensated on-line combustion pressure sensor in a rig and general aviation piston engine environment. The sensor shall be blind hole mounted to minimize impact to the test articles. The testing will consist of 1) a single cyclinder bench test; 2) 25 hours of engine performance testing consisting of a series of fuel mixture runs; and 3) 50 hours of engine endurance testing. Combustion pressure sensor data will be collected along with extensive rig and engine instrumentation data. The performance of the sensor during steady state and transient operation will be evaluated. NASA/GRC intends to provide funds for Phase I of the contract (6 months) with an option for Phase II (6 months) to Textron Lycoming, 652 Oliver St., Williamsport, PA 17701. Textron will subcontract to Oceana Sensor Technologies, Inc. The authority for other than full and open competition is 10 U.S.C. 2304 (c)(1) -- Only one responsible source and no other supplies or services will satisfy agency requirements. The statutory authority cited is applicable due to the unique nature of the pressure sensor being developed by Oceana Sensors Technologies,Inc.. This low cost sensor will have blind hole mounting capability near the combustion chamber surface, and will have an integrally mounted temperature compensation capability allowing it to provide accurate pressure measurements under rapid temperature variations as encountered during engine starting and transient conditions. No other sources are known which can provide instrumentation with these collective features. This technology was defined and initial developmental work commenced under the NASA sponsored Advanced General Aviation Transport Experiment (AGATE) program. To replicate this initial work through another source would come at a duplication of effort and additionalcost to the government. Textron Lycoming, a manufacturer of general aviation piston engines, is uniquely qualified to test and evaluate this instrumentation given their unique capabilities, engine knowledge (including specification drawings, installation requirements, and performance requirements), and test facilities. Interested organizations may submit their capabilities and qualifications to perform the effort in writing to the identified point of contact not later than 4:30 p.m. local time on March 24,2000. Such capabilities/qualifications will be evaluated solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. A determination by the Government not to compete this proposed effort on a full and open competition basis, based upon responses to this notice is solely within the discretion of the government. No RFP will be released because this notice is issued in response to an unsolicited proposal. The Government does not intend to acquire a commercial item using FAR Part 12. See Note 26. All qualified, responsible sources may submit a proposal that shall be considered by the agency. An Ombudsman has been appointed. See Internet Note "B".
