FROM: Dakota Collins/409 SCMS/GUME TO: DLA Aviation Procurement Operations at Warner Robins (SPRWA1) LOCATION: Robins AFB, GA 31098-1813 FBO Post Title: Request for Interested Manufacturers, 30MM GAU-8 Entrance Drum Cover NSN 1005-00-570-3715, Part Number 198F288 SUBJECT: The Government is conducting market research to identify potential sources that may possess the expertise, capabilities, and experience to meet the requirements for qualification and production of the 30MM GAU-8 Entrance Drum Cover NSN 1005-00-570-3715. NAICS: 332994 Item Description: NSN: 1005-00-570-3715 The A-10 aircraft drum cover assembly is mounted on each end of the outer drum. The exit end drum cover assembly (exit cover, P/N 198F216-1) is identical in function to the entrance end drum cover assembly (entrance cover, P/N 198F288-1); however, the exit cover is designed to carry all axial loads imposed on the drum. The entrance materials/composition is cast from entirely Aluminum (AL); MIL-A-21180, A356 Class 11 that is precision machined to tolerances up to two decimal places and surface tolerance up to three decimal places. All cast surfaces to have a 500 finish. Casting shall not be shot blasted. The exit and entrance covers are not interchangeable because of the differences in material and load bearing capacity. When the system is operating in the firing direction, round/spent cases are handed off from the entrance unit to the entrance cover. From the entrance cover the round/spent cases are handed off to the scoop disc and from the scoop disc to the drum and helix. At the exit end of the drum, the scoop disc picks the rounds/spent cases from the helix and hands them off to the exit cover. The exit cover feeds the rounds/spent cases to the exit unit. When the system is operating in the reverse (clearing) direction, all handoffs are the reverse of those just described. Retainer partitions, mounted on a retainer gear in each drum cover, control the rounds between the scoop discs and the entrance and exit units. A spring loaded timing pin on each cover is used to time the drum for installation of the entrance and exit units.
