Abstract
In the framework of the Italian National Space Research Program (PRO.RA), supported by the Italian Ministry of Education and Research (M.I.U.R), a dedicated technology project, managed by the Italian Aerospace Research Centre (C.I.R.A. S.c.p.A.) and aimed to assess the use of ultra high temperature ceramics in the manufacturing of future RLV hot structures, is now running. A multi-material structure, which couple diborides (addressed as the sole materials that can be conveniently employed at temperatures above 2200K) to a C/SiC frame, is under investigation with the aim to demonstrate an innovative concept of nose cap. The current state of the research work is presented and the to-date results are described. Experimental data related to plasma sprayed coatings and self-standing components as well as to hot isostatically pressed samples are reported and discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
