A -- COMPOSITE GUN BARREL TECHNOLOGY DEVELOPMENT-RESEARCH AND DEVELOPMENT DATA SOL N00178-95-R-1025 DUE 022495 POC Roger J. McAughan, Contract Specialist, Code S116, (703) 663-7478. Composite Gun Barrel Feasibility Demonstration which will entail the production of high strength filament wound composite materials developed for use on the Army HICAP Projectile and currently being used in the state-of-the-art gun barrel development for the Navy's composite gun barrel technology project. The contractor shall work with Naval Surface Warfare Center, Dahlgren, Division, Dahlgren, VA, and Army Research Laboratory (ARL), Aberdeen, MD to implement a timely and cost effective project. The following tasks will be conducted: (1) Complete the detailed design of the composite gun barrels and document the results. This entails completing the second iteration of the barrel design, factoring in the results of the pressure wave propagation analysis performed by ARL, and delivering the results to ARL in a form compatible with their three dimensional finite element modeling program to do a full model of the composite barrel. This design shall take into account both structural and thermal loading to which the composite barrels will be subjected. The contractor shall coordinate with both NSWCDD, and ARL to assure that the most efficient and cost effective use of facilities and manpower is obtained. (2) Develop and document the procedures and fixtures necessary for manufacture of the composite gun barrels at production rates on commercial filament winding apparatus. This effort will eliminate the need to conduct a manufacturing technology development program in order to build the barrels in production. (3) Formulate a development test program for the composite barrel design validation and a demonstration test program for the final composite barrel demonstration prototypes. All tests will be conducted at one of the aforementioned facilities. The contractor shall be required to assist the government in developing the details of the tests, monitoring the testing, and analyzing the results of the individual tests. (4) Provide training to government personnel who are doing the filament winding operation during the manufacture of test hardware and prototypes. This training will be in the areas of procedural training and use of developed fixtures necessary to produce the high strength composites. (5) Provide limited test hardware and/or prototype manufacture. This task will be used only if the government facility is not available, or use of contractor facilities is necessary to meet the project schedule. The proposed contract shall be negotiated with Custom Analytical Engineering Systems, Inc. (CAES), Star Route Box 4A, Flintstone, MD 21530 as CAES has developed a proprietary 3-Dimensional analysis code capable of meeting the composite material design applications necessary for the successful development of the composite gun barrel technology demonstration hardware.
