Preparation of edge wing for space re-entry vehicles

ISTEC designed and produced the material composition and coordinated the activities for the manufacture of a massive piece based on Si3N4-MoSi2 with large dimensions (520x220x150 mm). The production processes, involving mixing-granulation of powders and uniaxial hot pressing, were carried out under the guide of ISTEC. The final prototype was obtained by mechanical machining and was tested in plasma arc jets.
