10 -- MULTI-ROLE ELECTROTHERMALCHEMICAL ARMAMENT TECHNOLOGY SOL DAAE30-00-R-0332 DUE 091500 POC Sandy Chisholm, Contract Specialist WEB: US ARMY TACOM-ARDEC Procurement Network, http://procnet.pica.army.mil/cbd/RFP/00R0332/00R0332.htm. E-MAIL: Sandy Chisholm, schishol@pica.army.mil. The U. S. Army TACOM-ARDEC has a requirement for Multi-Role Electro-Thermal Chemical (ETC) Armament System for the Future Combat System Science and Technology Objective Program. Subject to J&A approval, the Government plans to negotiate with a single source pursuant to FAR 6.302-1(a)(2)(ii) to modify Contract No. DAAE30-99-C-1090 with General Atomics, 3550 General Atomics Ct, San Diego, CA 92191. It is likely that award to any other source would result in both (A) substantial duplication of cost to the Government that is not expected to be recovered through competition and (B) unacceptable delays in fulfilling the requirements. This effort involves the design and development of Electro-Rheological (ER) fluid controlled recoil mechanisms, Magneto-Rheological (MR) fluid controlled recoil mechanisms and weapon structural components utilizing isogrid structures. This effort supports the Multi-Role ETC Armament System for the Future Combat System (FCS). The contractor will leverage the ongoing Multi-Role ETC Armament System for FCS efforts to develop technologies utilizing ER fluids that assist in mitigating and managing recoil loads in large caliber weapon systems. Technologies to be developed/investigated utilizing ER fluids include soft-recoil mechanisms and active recoil control in conventional recoil mechanisms. In addition, the contractor will conduct a study to evaluate the use of MR fluids in mitigating and managing recoil loads. The contractor shall include in the study a comparative analysis of the benefits and disadvantages of ER and MR fluids. The contractor will leverage the ongoing Multi-Role ETC Armament System for FCS efforts to design and develop an armament turret assembly utilizing isogrid structures. The contractor shall support integration, assembly and developmental testing of the FCS turret assembly. The isogrid structures will provide the strength and stiffness required to support a large caliber armament system while minimizing the overall turret assembly weight. The contractor willdesign the turret assembly to interface the FCS vehicle chassis. In addition, the contractor will compare and contrast Isogrid structures to other structural technologies and investigate alternative materials for use with isogrids. Letter RFP DAAE30-00-R-0332 will be posted with the draft SOW revisions for information purposes at the following website: http://procnet.army.mil. See Note 22. Posted 08/15/00 (D-SN486230). (0228)
