66 -- MISSILE FIN HEAT PIPE SOL F33601-96-R-A014 DUE 012596 POC For copy, ASC/PKWO, Attn: Bldg 260, 1940 Allbrook Dr Ste 3, WPAFB OH 45433-5309, POC: C Marion, 513-257-5184, Fax No 513-257-3926. Purchase of one (1) Missile Fin Heat Pipe to be built inside a NACA 0015 airfoil of chord length 0.1143 m. The total length of the heat pipe will only be a small portion of the 0.254 m span of the fin. The first 0.05 m of the fin will be heated by the exhaust plume. The heat pipe shell will have to withstand a pressure difference of approximately 1.7 atmospheres during flight. The heat pipe will be subjected to a launch acceleration load of 2g along the launch flight path until a maximum speed of Mach 0.75 is reached (i.e., this acceleration is expected to be 20 seconds). The bottom fin on the missile will be placed in an evaporator up configuration requiring the the working fluid to wick up against gravity. Little maneuvering is anticipated until the final few seconds of flight. There must be an axial hole 0.0159 m diameter, though the heat pipe for an actuation rod. Operating temperature: 800-900K, wall material: 304 stainless steel, working fluid: sodium, configuration shape: NACA 0015 (C = 0.1143m), wall thickness: 0.0023m, evaporator length: 0.050m, input power: 3,186 W@ Te = 850K, total fin lenght: 0.254m, acceleration field: short duration 3g, evaporator location: inner most portion of fin. Simplified acquisition procedures are contemplated. This solicitation will be issued approx 96 Jan 11. All responsible sources may submit a bid, proposal, or quotation which shall be considered. No tel requests. Only written or faxed requests received directly from the requestor are acceptable. (0362)
