E-MAIL: Patricia B. Nickells, pnickel@pica.army.mil. Interested parties are being sought for the continued development of an elastomer type breech seal for the XM297 Cannon, which utilizes a 2 piece breechblock. This cannon will be used in the Crusader 155mm self propelled howitzer. This seal must be fabricated from a compound which will provide sealing upon closing and retain resiliency upon opening. It will be required to operate in an extremely harsh environment sealing in propellant gases at a chamber pressure of 58,800 psi while encountering high levels of residue from the burnt propellant. In addition, the breech seal must meet requirements for rates of fire of 12 rounds per minute, 448 rounds fired prior to cleaning, and a seal life of 6 battlefield days or 2688 rounds. To maintain current contract schedules, the seal must be developed by the end of April 1998. This market survey does not constitute a solicitation for proposals. All information required in Numbered Note 25 should be submitted to: US Army TACOM ARDEC, AMSTA-AR-PC-E, Bldg 10, ATTN: Patricia Nickells, Picatinny Arsenal, NJ 07806-5000. See Numbered Note(s): 25.
