  • COMPOSITE LAYER SYSTEM HAVING AN ADDITIVELY MANUFACTURED SUBSTRATE AND A CERAMIC THERMAL PROTECTION SYSTEM
    Publication number: 20220381151
    Abstract: A composite layer system is presented. The composite layer system includes a metallic substrate, a structured surface, and a thermal protection system. The structured surface may be additively manufactured onto the metallic substrate and includes structured surface features formed to project above the metallic substrate. Each of the structured surface features are separated from adjacent structured surface features by grooves. The thermal protection coating may be thermally sprayed onto the structured surface and is bonded to each of the structured surface features.

  • Device and system for selectively detecting gas components or concentrations of gas components in gas to be analyzed and method for operating such device
    Patent number: 8916827
    Abstract: A photonic crystal, which is a periodically arranged structure made of free-standing columns, has a base material of at least one metal or a metal alloy. Intermediate spaces between the columns allow passage of a gas to be analyzed. The photonic crystal has predefined imperfections, by which at least one resonator is formed, the resonant frequency of which is in a frequency range which is absorbed by a gas component to be detected. A heating unit heats at least some of the columns and at least one detector element extracts the energy present in the resonator in the heated state under the action of the gas to be analyzed. The device may have extremely small dimensions and very low energy consumption.
