Abstract

Procédé d'occultation des radiations infrarouges émises par des points de sortie de gaz chauds, tels qu'embouts d'échappement de moteurs à combustion interne, pour les rendre imperceptibles à des appareils de détection de rayons infrarouges. Il consiste à entourer l'embout 2 d'un tube extérieur 1 prolongé au-delà de l'embout et incurvé en direction de la sortie des gaz; ce tube extérieur véhiculant un agent réfrigérant gazeux 3 enveloppant de façon laminaire le gaz d'échappement chaud 4. L'invention concerne également un dispositif de mise en oeuvre dudit procédé, comportant éventuellement une soufflante placée en amont de l'embout et dont la vitesse de rotation est réglée en fonction de celle du moteur à combustion interne.
