    Applying Taguchi Methods To Brazing Of Rocket-Nozzle Tubes (1995)
    In:  Other Sources
    Details
    Publication Date: 2019-07-13
    Description: Report describes experimental study in which Taguchi Methods applied with view toward improving brazing of coolant tubes in nozzle of main engine of space shuttle. Dr. Taguchi's parameter design technique used to define proposed modifications of brazing process reducing manufacturing time and cost by reducing number of furnace brazing cycles and number of tube-gap inspections needed to achieve desired small gaps between tubes.

    Alignment Tool For Welding Sensor (1992)
    In:  Other Sources
    Details
    Publication Date: 2019-07-12
    Description: Alignment tool enables accurate positioning of optoelectronic sensor measuring weld penetration. Designed for use on tungsten/inert-gas welding apparatus, used to adjust position of sensor so photodiode puts out maximum signal. Tangs of slotted cap bent slightly inward to provide spring force holding cap snugly on sensor mount. Tool installed and removed without aid of other tools. Length of pointer adjusted with set-screws. Used with variety of gas cup and electrode lengths.

    In Situ Robotic Inspection Of Welds (1992)
    In:  Other Sources
    Details
    Publication Date: 2019-07-12
    Description: Automated system reduces delays in inspection and rework. System reduces inspection-and-rework delay from days to hours. Path of inspection sensors taken directly from welding path saving time in programming for inspection. Inspection data stored so not lost as inspection equipment turned off. Same robot welding workpiece used to inspect it. In preparation, welding tool mounted on end effector of robot replaced with eddy-current or ultrasonic sensor. Robot recalls welding path from memory and retraces it, recording sensor output as it proceeds.

    Robotic System Would Inspect Tubes And Fillets (1993)
    In:  Other Sources
    Details
    Publication Date: 2019-07-12
    Description: Proposed robotic system inspects arrays of brazed tubes being fabricated for use in heat exchangers and similar objects. Arrays contain coolant tubes mounted in nozzle of main engine of Space Shuttle. Other versions used to inspect components of terrestrial heat exchangers for powerplants, vehicles, and refrigeration equipment. Inspection system provides for automated, complete, objective, and efficient inspection of arrays of coolant tubes. Computer executing image-processing algorithms extracts profiles of tubes and braze fillets and identifies flaws.

    Adaptive Machining Of Large, Somewhat Flexible Parts (1996)
    In:  Other Sources
    Details
    Publication Date: 2019-07-13
    Description: Adaptive machining is method of machining large, somewhat flexible workpieces to close tolerances. Devised for machining precise weld lands on aft skirts of rocket nozzles, but underlying concept generally applicable to precise machining of any of large variety of workpieces deformed by thermal, gravitational, and/or machining forces. For example, in principle, method used to bore precise hole on unanchored end of long cantilever beam.
