70 -- HIGH SPEED EVENT ACQUISITION BOARD SOL F33601-97-R-0140 DUE 030697 POC For copy, G. Johnson/Pkwre/[937]257-6721, For additional information contact G. Johnson/Pkwre/[937]257-6721 This is a combined synopsis/solicitation for commercial items prepared in accordance with the format in Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation proposals are being requested and a written solicitation will not be issued. This solicitation is issued as a Request for Proposal (RFP) and this includes all provisions and clauses in effect thru FAC 90-40. This is a sole source requirement IAW FAR 6.302-1. This RFP has the following line item: 0001 2 EA High Speed Event Acquisition Board is required to gather data from a 12 channel light probe system. This system will be used to acquire data about blade vibration frequencies and amplitudes in a spinning jet engine component. Each light probe delivers a laser beam to the tip of a rotating jet engine fan or compressor blade. The optical signal scattered from the blade tip is collected by the light probe and converted to a TTL level (5 volts) pulse. The width of the TTL pulse will be approximately 3 microseconds. The VME card must also monitor a once per revolution signal. The once per revolution signal is a 0 to 5 volt pluse and will be 10 microseconds wide. The VME card which will gather data from the light probes and the once per revolution signal shall have the following capabilities: (1) the card shall handle output from 12 light probes, (2) the card will measure the time between the once per revolution signal and each of the light probe pulses to a precision of 5 nanoseconds, (3) requires a clock speed of at least 200MHz, and (4) The card shall report both the leading and trailing edge of each pulse. The output of the card shall consist of a 3-byte time stamp for each event and a 1-byte event code indicating which of the 12 light probes had detected a blade passage. The clock shall be reset to zero by the once per revolution signal. The 1-byte event code indicating which of the 12 light probes had detected the blade passage will have its sign bit set if the event is a trailing edge. An engine with 70 blades, and a speed of 250 rev/sec, this will generate 1,680,000 bytes of data per second (70 blades, 12 probes, 4 bytes/event, 250 rev/second, 2 events per blade passage). This data will be stored in an on-board FIFO of at least 320k bytes so that the host computer need not do more than five DMA reads per second. The host must see the data continuously for several hours, there should be no gaps in the data. Item 0002 1 EA 72" Base Equipment Rack. Item 0003 1 EA Equipment Rack Panel, Sides and Fan kit. The approximate issue/response date will be 18 Feb 97. The anticipated award date will be 07 Mar 97. Written procedure will be used for this solicitation. No telephone requests. Only written or faxed requests received directly from the requestor are acceptable. All responsible sources solicited may submit a bid, proposal, or quotation which shall be considered. Authority: 10 U.S.C. 2304(C)(1), Justification: Supplies (or Services) required are available from only one or a limited number of responsible source(s) and no other type of supplies or services will satisfy agency requirements. The proposed contract action is for supplies and services for which the Government intends to solicit and negotiate with only one, or a limited number of sources under the authority of FAR 6.302. Interested persons may identify their interest and capability to respond to the requirement or submit proposals. This notice of intent is not a request for competitive proposals. However, all proposals received within forty five-days (thirty days if award is issued under an existing basic ordering agreement) after date of publication of this synopsis will be considered by the Government. A Determination by the Government not to compete this proposed contract based upon responses to this notice is solely within the discretion of the Government. Information received will normally be considered solely for the purpose of determining whether to conduct a competitive procurement. An Ombudsman has been establishedfor this acquisition. The only purpose of the Ombudsman is to receive and communicate serious concerns from potential offerors, when potential offerors prefer not to use established channels to communicate their concerns. Potential offerors should use established channels to request information, pose questions, and voice concerns before resorting to the Ombudsman. Potential offerors are invited to contact the ASC Ombudsman, Mr. Daniel Kugel, ASC/SY, 2475 K Street, Suite 1, Wright-Patterson AFB, OH 45433-7303, telephone: (937) 255=A93855, with serious concerns only.
