EMISSIVITY CHARACTERIZATION OF CARBON SILICON CARBIDE COMPOSITE FOR TPS THOROUGH PLASMA WIND TUNNEL TEST: EXPERIMENTAL VALIDATION

摘要

The properties of a Thermal Protection System (TPS) have crucial impact on the success of a reentry missionand the proper design of a space vehicle. TPS are mainly cooled by radiation, which prevents the temperature ofthe surface material to exceed its melting point. This capability of radiative cooling is strongly dependent on thechemical and on the optical properties of coating.This work reports the result of in-situ measurements of catalytic and oxidative behaviour conducted on TPSmaterial of Dipartimento di Ingegneria Astronautica Elettrica ed Energetica of Sapienza Università di Roma inthe framework of ASA Phase B2 program and cover a large range of typical hypersonic reentry conditions.
