The optimization of functionally graded metal matrix composites (FGMMCs) has long been hindered by the complex interplay between reinforcement distribution, process constraints, and multifunctional performance objectives. Current data-driven and empirical frameworks...
Ultra-low-noise amplifiers developed by European Engineering & Consultancy Ltd. (EECL) are now operating successfully in orbit on the European Space Agency’s HydroGNSS Earth observation mission, marking an early technical milestone for the satellite payloads. The...
Phase-change materials (PCMs) are capable of storing or releasing a substantial amount of thermal energy within a small volume through the latent heat of fusion during phase transitions of melting and solidification, i.e., from solid to liquid or vice versa, in a near...
Récemment, un ressort en titane imprimé en 3D s’est déployé à bord d’un petit vaisseau commercial, le Mercury One. Mais quelle est cette curiosité du Jet Propulsion Laboratory (JPL) de la NASA ? Quelle est son utilité ? Pourquoi un tel projet ? Pour l’agence spatiale...
Spaceborne power systems must operate reliably for decades with minimal maintenance. Thermoelectric generators (TEGs) are intrinsically suited to long-lived missions, but their output remains constrained by available thermal gradients and the limitations of bulk...
Quatre années. C’est le temps qu’il aura fallu pour que le projet Tbatt-Diamond aboutisse à un générateur bêta-voltaïque au diamant-tritium, sous l’égide d’un consortium 100% français. Avec un rendement de conversion de 10,5%, cette batterie nucléaire est en mesure de...
