R -- AUTOMATION OF INFLIGHT REFUELING DUE 091297 POC For copy, Ramos, D./sfk/[210]925-1175, For additional information contact Ramos, D./sfk/[210]925-1175 Automation of Inflight Refueling Transactions/Request For Information: The purpose of this request is to determine the availability and economic feasibility of off-the-shelf technology that,with minimal adaptation, could automatically capture data for processing inflight refueling transactions. Data requirements from the receiving aircraft are estimated at 400 bytes and include customer (home station and Major Command) identification, tail number identification, aircraft MDS, organizational code, signal code, fund code, product code, alternative products codes, and billing address. Data requirements from the dispensing aircraft are estimated at 205 bytes and include identification of product grade, quantity of fuel dispensed, product grade code, transaction date, tanker MDS, and tanker tail number. (Many tankers provide fuel transaction data via the 1553 data bus used with the Fuel System Advisory System (FSAS). Total memory requirement per transaction is estimated at 605 bytes. If the data is stored and downloaded for each mission, then total memory must permit storage of 20 transactions. U.S. Air Force tanker aircraft dispense fuel to receiver aircraft, including other military service and foreign government aircraft. The equipment used must be able to operate with high reliability in the inflight refueling environment involving speeds in excess of 400 knots, temperatures ranging from -60 degrees to +130 degrees centigrade, and with minimal light The technology must permit the independent identification of two aircraft receiving fuel simultaneously while other receiver aircraft in the immediate vicinity await service. Since the technology must be compatible with both refueling boom and probe and drogue refueling methods, contract data transfer technologies may not be feasible. For electromagnetic technologies, the data transmission distance is estimated to be 150 feet. However, since refueling may occur during periods when electronic transmissions are not allowed, the signal strength must not pass beyond1,000 feet. A messaging system is also needed to communicate the daily transaction data from the aircraft to the home station or a central billing activity. All responses to this request should be written and should be received not later than September 12, 1997. (THIS DATE HAS BEEN EXTENDED FROM SEPTEMBER 2, 1997.) The POC (point of contact) is David Ramos/SFK/PHONE:(210)925-1175/(210)925-7248/FAX (210)925-9758/Directorate of Aerospace Fuels. Proprietary information will not be disseminated outside of government agencies without your approval. All comments will be reviewed and will be considered for incorporation in the draft (if issued) and final Request for Proposal (RFP) (if issued). NOTE; THIS REQUEST IS FOR INFORMATION ONLY AND IS NOT TO BE MISCONSTRUED AS A SOLICITATION FOR ___ __ __ __ __ ____ PROPOSALS. NOTE: THIS REQUEST IS FOR INFORMATION ONLY AND IS NOT TO BE MISCONSTRUED AS A SOLICITATION FOR PROPOSALS. The approximate issue/response date will be 04 SEP 97. No telephone requests. Only written or faxed requests received directly from the requestor are acceptable. (0248)
