Perspectives for Exploitation of Thermoelectric Generators on Future European Launchers

Autor: Ralf Knoche, Wolff-Dieter Ebeling, Johannes Sebald

Publikováno v: Materials Today: Proceedings. 2:833-848

Inthis paper, the application of COTS (Commercial of-the-shelf) TEGs (Thermoelectric Generator) of Bi 2 Te 3 type for power supply of autonomous sensors has been investigated. Architecture of a TEG system has been established and the expected electri

Improvement of Oxide/Oxide CMC and Development of Combustor and Turbine Components in the HiPOC Program

Autor: Thomas Aumeier, Dietmar Koch, Ralf Knoche, Thays Machry, Sandrine Denis, Yannick Cadoret, Christian Wilhelmi, Kamen Tushtev, Miklo´s Gerenda´s, Ju¨rgen Go¨ring, Thomas Behrendt

Publikováno v: Volume 1: Aircraft Engine; Ceramics; Coal, Biomass and Alternative Fuels; Wind Turbine Technology.

Three different oxide/oxide ceramic matrix composite (CMC) materials are described. Design concepts for the attachment of the CMC component to the metal structure of the gas turbine are developed in a first work stream focused on the combustion chamb

Evaluation of mechanical properties and comprehensive modeling of CMC with stiff and weak matrices

Autor: Georg Grathwohl, Jürgen Horvath, Kamen Tushtev, Ralf Knoche, Dietmar Koch

The mechanical properties of ceramic matrix composites (CMC) depend on the individual properties of fibers and matrix, the fiber-matrix interface, the microstructure and the orientation of the fibers. The fiber-matrix interface of ceramics with stiff

Ceramic matrix composites life cycle testing under reusable launcher environmental conditions

Autor: Giorgio Tumino, Ulrich Trabandt, Ralf Knoche, Dietmar Koch, Burkhard Esser

This article focuses on the thermal protection system (TPS) and hot structures based on carbon fiber-reinforced SiC (C/SiC) material, which protects the high thermal-loaded areas and control surfaces of a reusable launch vehicle (RLV). The goal of th
