- Abstract
Smart materials and systems could represent an interesting alternative to current TPS for future RLVs(reusable launch vehicle).Smart systems can be defined as systems able to “feel” their thermo-mechanical environment and to change their basic physical properties to “react or adapt” to the environment so that the effects are reduced. A ESA Contract work has been performed by INASMET-TECNALIA to study smart TPS concepts based on EVEREST SSTO laucher specifications. The identification of smart concepts, study their feasibility and selection by comparison to a selection criteria list. The Smart active TPS studied were: Sensor/actuator to vibration damping control by piezoceramics able to sustain 650ºC. TPS Health monitoring within piezoelectric based on emitted/received microvibrations. Actuation (moving, tilting, owering) “morphing” tiles for aerothermodynamic changes. TPS monitoring: thermal sensitive coatings. Phase change materials for temperature control (hot/cold parts attachments). In situ repair: Self-healing materials (micro-capsules dispersed on metallic parts, doped ceramics to react with oxygen producing glasses) Materials with adaptable properties (FGM) functional graded materials Adapting CTE on stand-offs. Tailoring thermal conductivity A proof-of-concept of the two most promising smart concepts selected were manufactured and evaluated on representative environment.
