Abstract

Dans une mémoire pour un enregistreur de données de vol (10), les unités de mémoire à semiconducteurs (26) sont encapsulées dans une cire organique synthétique (28) qui présente une transition solide-liquide à une température : (a) supérieure à la température de fonctionnement normale de la mémoire (10) et inférieure à la température de crete acceptable pour les unités de mémoire (26). La cire (28) est entourée par un garnissage isolant (18). Une enceinte métallique (12) contient et protège le tout.In a memory for a flight data recorder (10), the semiconductor memory units (26) are encapsulated in a synthetic organic wax (28) which exhibits a solid-liquid transition at a temperature: (a) higher than the normal operating temperature of the memory (10) and lower than the peak acceptable temperature for the memory units (26). The wax (28) is surrounded by an insulating lining (18). A metal enclosure (12) contains and protects everything.
