  • Reactants sprayed into plasma flow for rocket propulsion
    Patent number: 9505503
    Abstract: Specific impulse and rocket engine efficiency can be improved by injecting reactants, e.g., a propellant combination or a monopropellant and a catalyst, into a plasma flow of a rocket engine. In some aspects, a catalyst or a propellant is carried by plasma formed by passing a flow of a feed gas through an electrical arc. In some aspects, reactants are combusted in supersonic plasma flow to generate combustion ionization in the plasma flow.
    Type: Grant
    Filed: March 24, 2014
    Date of Patent: November 29, 2016
    Assignee: Lockheed Martin Corporation
    Inventors: Larry D. Knauer, Edward A. Pierson, Vadim Khayms

  • Ceramic coatings to protect cellulosic products
    Patent number: 5707752
    Abstract: A cellulosic substrate is impregnated using a plasma gun. A plasma spray of a ceramic material is applied to a first surface of the cellulosic substrate. The ceramic material improves various properties of the first surface of the cellulosic substrate.

  • White thermal control surfaces
    Patent number: 5567490
    Abstract: The present invention resides in a white thermal control surface resistant to darkening due to exposure to X-rays and ultraviolet radiation. The surface comprises a substrate and a ceramic zirconium orthosilicate coating on said substrate. The zirconium orthosilicate coating is obtained by plasma-spray applying particles of zirconium orthosilicate onto the substrate. The particles of zirconium orthosilicate are doped with an oxide of a +3 valent metal. The metal ions of said +3 valent metal oxide are dispersed substantially uniformly throughout said particles.
