- This notice is a combined synopsis/solicitation for commercial items prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; offers are being requested and a written solicitation will not be issued. NASA Ames has a requirement for Diagnostic Ports for Arc Driven Shock Tubes. This notice is being issued as a Request for Quotations (RFQ) for three types of instrumentation ports for the NASA Ames Electric Arc Shock Tube (EAST) facility. Each port shall be a complete assembly that will attach directly to the test section of the driven portion of the shock tube. Shock Tube Environment Specifications: The driven portion of the shock tube operates as both a vacuum and pressure vessel. The base pressure of the driven tube is < 5x10(to the -7th power) torr. All components of the shock tube are rated to a maximum allowable pressure of 4.85 MPa (700 psia). The shock tube is exposed to a variety of pure gases, gas mixtures, and their reaction products. These include the following: Air; N2; N2/CO2 mixture; CH4/N2 mixture; H2/He mixture. Reactive species from these gases are produced by the shock wave. Shock speeds up to 30 km/s have been achieved. The shocked gases can reach temperatures approaching 15,000 K for brief durations (milliseconds) before heat dissipation. Under normal operating conditions, the post-shock pressure can reach 200 kPa. The electric arc driver of the shock tube also produces super-heated gases and vaporized solids that will reach the driven tube and test section following passage of the shock wave. These include helium, argon, nitrogen, Teflon, tungsten, mylar, and aluminum alloys. The diagnostic ports will be mounted to a 6061 aluminum alloy test section that is part of the driven tube. The inner diameter of the shock tube is 4.0? (10.16 cm). Port materials: The metallic surfaces of the ports exposed to the interior of the shock tube shall be made of 6061-T6 aluminum alloy. The vacuum/pressure sealing o-rings shall be perfluorinated elastomers (Parker Parofluor or equivalent). The window materials for the ports shall be 1) fused silica, for ultraviolet to infrared transmission and 2)either magnesium floride (MgF2) or lighium floride (LiF)for vacuum ultraviolet transmission. Port vacuum, pressure, and temperature performance: Vacuum pressure < 10(to the -8th power) torr (1.33 x 10 (to the -6th power) Pa); Positive pressure (> or = to) 4.85 MPa; Leak rate < 10 (to the -8th power) atm cm(to the 3rd power)/s He; Bakeout temperature (> or = to) 80 degrees C; Operating temperature (> or = to) 25 degrees C. Requirements for this study are as follows: Vacuum leak rate and static pressure testing to the above specifications is required for acceptance. Each complete port assembly shall be tested and documented. A description of the test apparatus is required. All machining shall be performed using tools and methods compatible with ultra high vacuum service. Port specifications applicable to all configurations are listed below: The port design shall have a primary insert body attached with fastening bolts to the shock tube test section. A secondary insert containing the relevant diagnostic hardware (window, fiber optic collimator, pressure transducer) shall be inserted into the primary insert body and attached with fastening bolts. The secondary inserts will be removed after every experiment for cleaning. The seals between 1) the primary insert and shock tube test section, and 2) secondary and primary inserts shall meet the pressure and vacuum specifications listed above. The inner surface of the inserts shall be conformal with cylindrical wall of the shock tube test section; the inserts shall not introduce protrusions or recesses in the shock tube wall. The radius of the conforming wall of the primary insert, defined by the circular shock tube cross section, shall be 2.0?. The insertion depth shall be 1.750? as measured from the bottom of the primary insert flange to the apex of the conforming wall. The thickness of the primary insert flange shall be 0.5?. All fasteners shall be 1/4 -28 screws. The primary insert shall have 316 stainless steel threaded inserts for the secondary fasteners. The ports shall have internal 120 VAC bakeout heaters where possible. All vacuum sealing surfaces shall be polished to a surface finish compatible with the above vacuum leak rate requirement. Two spare o-ring kits shall be provided for each complete port assembly. Detailed specifications of the port types are listed below: Rectangular window port: Two (2) rectangular window ports are required. One shall have a fused silica window, and the other shall have either an MgF2 or LiF window. The windows shall be mounted in the secondary insert with a retaining o-ring. The fused silica window secondary insert shall have a clear aperture 0.5? high and 4.75? long. The MgF2 or LiF window secondary insert shall have a clear aperture 0.5? high. The length of the window shall be the maximum possible with commercially available crystal boules, but must be at least 2.9? long. The long dimensions of the windows shall be oriented parallel to the shock tube axis. The inside window face shall be tangent with the cylindrical wall of the shock tube. The window mounting scheme must be designed to allow the windows to withstand the impulsive pressure load from a shock wave traveling across the window. The dimensions of the primary insert inset shall be 1.75? high, 4.75? long with 0.875? radius ends. The dimensions of the primary insert flange shall be 3.75? high, 4.75? long with 1.875? radius ends. The port flange shall have face seal and fastening bolt provisions for connection to an external vacuum chamber. Access to the fastening bolts for this connection shall be external to the chamber. The thread inserts shall be 316 stainless steel. Two (2) blank secondary inserts are required (solid ? no window). Three (3) spare fused silica windows are required. Three (3) spare MgF2 or LiF windows are required. Circular diagnostic ports: Two types of circular diagnostic ports are required: window and pressure transducer. Both types shall have a common primary insert ? the secondary insert containing the window or pressure transducer will fit in any circular primary insert. The primary and secondary inserts shall have the following common specifications: The diameter of the primary insert inset shall be 1.1875?. The diameter of the primary insert flange shall be 2.1875?. The thickness of the secondary flange shall be 0.5?. Circular diagnostic port type one - window ports: Twelve (12) circular window ports are required. The windows shall be mounted to the secondary insert with a retaining o-ring. The window secondary insert shall have a clear aperture of 0.5? diameter. The window secondary insert shall place the inside window face tangent with the cylindrical wall of the shock tube. The outer face of the secondary flange shall have four 316 stainless steel threaded inserts for 4-40 threads in a square pattern. The fastener insert locations on the secondary flange shall be compatible with the 16 mm cage construction system of Thorlabs, Inc. (part no. SP03). The center of the SP03 plate shall be coincident with the central axis of the secondary insert. Fifteen (15) fused silica windows (11 + 4 spares) are required. Three (3) MgF2 or LiF windows (1 + 2 spares) are required. Circular diagnostic port type two - pressure transducer port: Eight (8) pressure transducer ports are required.
