58 -- FLIGHT DECK SAFETY HELMETS WITH INTEGRAL COMMUNICATIONS CAPABILITY SOL N65236-00-S-0001 DUE 031600 POC Natalie Mueller, Code 514NM, (757)558-6706, FAX (757)396-0411 E-MAIL: click here to contact the point of contact via e-mail., muellern@spawar.navy.mil. SPAWAR Systems Center Charleston is seeking technical descriptive information from potential sources of safety helmets with integral radio communications capability suitable for use in the rugged environment of a U.S. Navy flight deck, characterized by: multiple nearby high-RF sources from HF to Infrared; frequent rough handling/dropping/banging; extremely high ambient noise (up to 140 dB-A sound pressure level); high wind; high moisture/precipitation; frequent exposure to aircraft fuels and lubricants; and high exposure to salt-water spray. The desired helmet has two ear speakers, mike, PTT-switch, and cable to a belt-carried radio. Desirable construction features include: a. replaceable gel-filled earcup seals for user comfort and noise reduction. b. high overall reduction of ambient noise level, both to protect hearing and to maximize speaker intelligibility. c. flexible, rugged microphone boom, with no mechanical parts such as screws, clamps, nuts, etc. Alternate types of microphones, such as throat-mikes or ear-mikes may also be desirable. d. ruggedized PTT-switch and switch-mounting. e. noise-cancelling mike with 5 Ohms nominal impedance at connector. f. non-corroding hardware to eliminate galvanic corrosion and oxidation/rust. g. soft, comfortable, durable padding. h. secure attachment of all parts to eliminate hazards to aircraft from loose parts on deck. i. speakers wired in parallel with 6.5 to 8.5 Ohms nominal impedance at connector. j. minimal vulnerability to audible RF interference. k. flexible radio connection cable with LEMO connector; cable/connector assembly ruggedized to withstand snagging, rough handling, etc. l. high resistance to weathering and exposure to flight deck fuels/lubricants. Interested potential sources are requested to forward technical descriptive data, prices, availability, ordering sources, and information concerning current use in other aviation-related applications, by 3/16/2000, to: (US Mail) -- SPAWARSYSCEN Charleston, ATTN: Natalie Mueller, Code 514NM, PO Box 1376, Norfolk VA 23501-1376; or: (Delivery) -- SPAWARSYSCEN Charleston, ATTN: Natalie Mueller, Code 514NM, Building 172, Wood Road, St Juliens Creek Annex, Portsmouth VA 23702; or: (FAX) to (757)396-0411 ATTN: Natalie Mueller, Code 514NM. Interested potential sources who send the requested information to Code 514NM are also requested to send an information copy of the cover letter (no technical or descriptive information needed) to: SPAWARSYSCEN Charleston, ATTN: Jean Duncan, Code 1115, P.O. Box 190022, N. Charleston, SC 29419-9022. The technical information is requested to allow Code 514NM to compare and evaluate the suitability of commercially available communications headsets for use in the rugged environment of a U.S. Navy flight deck. Small quantities (under 10 quantity) of some headsets may be procured for further evaluation if they appear to be suitable; however, there is no large-scale procurement planned at this time. THIS SYNOPSIS IS FOR INFORMATIN AND PLANNING PURPOSES AND IS NOT TO BE CONSTRUED AS A COMMITMENT BY THE GOVERNMENT. THIS IS NOT A SOLICITATION ANNOUNCEMENT FOR PROPOSALS AND NO CONTRACT WILL BE AWARDED FROM THIS ANNOUNCEMENT. NO REIMBURSEMENT WILL BE MADE FOR ANY COSTS ASSOCIATED WITH PROVIDING INFORMATION IN RESPONSE TO THIS ANNOUNCEMENT AND ANY FOLLOW-UP INFORMATION REQUESTS. RESPONDENTS WILL NOT BE NOTIFIED OF THE RESULTS OF THE EVALUATION. Posted 02/14/00 (W-SN425232). (0045)
