Le projet : Je suis Vincent Marsat, cette page est celle de mon projet de diplôme de design en nouvelles technologies que voici Les Dryades sont les gardiennes des pommes d’or du Jardin d’Eden. Le satellite de type “Dryade” est censé protéger l’espace. Petits, légers et lancés aux cotés d’autres satellites, ils doivent atteindre l’orbite des déchets spatiaux pour les attraper, les percer à l’aide de leurs perceuses, puis les coudre ensemble, et les placer sur un module qui sera ensuite détaché du satellite avec son chargement pour aller brûler dans l’atmosphère. Concrètement celui-ci possède 2 paires de pinces (une paire d’accroche, une paire de “bricolage” avec perceuses intégrées), et un chargement de modules. Ces modules sont des cubes de 20cm de coté possédant des amortisseurs, et un système de lancement très spécial: des explosifs sur une plaque de blindage concave, de manière à accélérer via une explosion contrôlée pour économiser la fabrication, et le poids du couple propulseur-réservoir d’ergols (carburant). Que reste-t-il à faire? – Définition des systèmes – Design des bras mécaniques – Placement des caméras – Montage d’un détecteur de distance laser – Module et système de mise à feu et de fixation sur le satellite – Pliage du satellite en vue d’être placé dans la coiffe d’Ariane 5 aux coté d’un autre satellite. La réalisation de ce projet se fera via un prototype et non un modèle réel (trop cher). Certaines contraintes seront donc évitées (utilisation d’arduino et de raspberry au lieu de réels appareils, trop cher). Je souhaites donner la possibilité à chacun de se faire sa propre idée du satellite, et vous aurez à...
