This engineering effort is to reverse engineer the core of the B?2 Load Heat Exchangers, develop disassembly process to remove defective cores, develop a stacking, vacuum brazing and welding process to manufacture new heat exchanger cores and to develop a welding process to install the new cores on existing B?2 Load Heat Exchangers. The requirement includes reverse engineering the re?core process for the B?2 Load Heat Exchangers. The B?2 Load Heat Exchanger (NSN 1660?01?350?8209FW) uses air and Ethylene Glycol Water (EGW) liquid to produce cold air for the cooling system.
