  • Method of producing a plug-type heat flux gauge
    Patent number: 5086204
    Abstract: A method of making a plug-type heat flux gauge in a material specimen in which a thermoplug is integrally formed. The thermoplug and concentric annulus are formed in the material specimen by electrical discharge machining and trepanning procedures. The thermoplug is surrounded by a concentric annulus through which thermocouple wires are routed. The end of each thermocouple wire is welded to the thermoplug, with each thermocouple wire welded at a different location along the length of the thermoplug.
    Type: Grant
    Filed: April 8, 1991
    Date of Patent: February 4, 1992
    Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space Administration
    Inventors: Curt H. Liebert, John Koch, Jr.
