CA 2192963

An underwater two-phase ramjet propulsion unit includes an inlet (104) for receiving a flow of water, a compressed gas injector (132, 134) for injecting compressed gas into the flow of water a mixing chamber (106) for mixing the compressed gas with the water to provide a two-phase flow of working fluid, and a nozzle (108) for accelerating the two-phase working fluid to generate a two-phase jet. The propulsion unit can be implemented with fixed geometry or variable geometry. The propulsion unit includes a supersonic gas injector (132) as well as a subsonic gas injector (134). The propulsion unit includes a control system (110) for controlling the compressor (122), supersonic gas injector (132), subsonic gas injector (134), the geometry of the unit, and the direction of the thrust vector.

Une unité de propulsion à statoréacteur biphasique sous-marin comprend une admission (14) de l'écoulement de l'eau, un injecteur à gaz comprimé (132, 134) qui injecte un gaz comprimé dans l'écoulement d'eau, une chambre de mélange (106) mélangeant le gaz comprimé à l'eau afin d'obtenir un écoulement biphasique de fluide actif, et un ajutage (108) accélérant le fluide actif biphasique pour générer un jet biphasique. L'unité de propulsion peut être conçue avec une géométrie fixe ou variable. Elle comprend un injecteur de gaz supersonique (132) ainsi qu'un injecteur de gaz subsonique. Cette unité de propulsion comprend un système de commande (110) qui commande le compresseur (122), l'injecteur de gaz supersonique (132), l'injecteur de gaz subsonique, la géométrie de l'unité et le sens du vecteur de poussée.
