Variable cycle propulsion device for supersonic aircraft having at least one propulsion unit (1) capable of generating thrust for supersonic flight speeds and at least one auxiliary propulsion assembly (16), distinct from the propulsion unit, capable of generating additional thrust for take- off, landing and subsonic flight speeds. The auxiliary propulsion assembly (16) has no gas generator and it is provided with the means (20) of transmission of part of the mechanical power produced by the propulsion unit to the auxiliary propulsion assembly so that the latter generates additional thrust for take-off, landing and subsonic cruise flight, and means for decoupling the means (20) of transmission for supersonic cruise flight.

Dispositif de propulsion à cycle variable pour avion supersonique comprenant au moins un propulseur (1) capable de générer une poussée pour les vitesses de vol supersonique et au moins un ensemble propulsif auxiliaire (16), distinct du propulseur, capable de générer un complément de poussée pour le décollage, l'atterrissage et les vitesses de vol subsonique. L'ensemble propulsif auxiliaire (16) est dépourvu de générateur de gaz et il est prévu des moyens (20) de transmission d'une partie de la puissance mécanique produite par le propulseur vers l'ensemble propulsif auxiliaire afin que celui-ci génère un complément de poussée pour le décollage, l'atterrissage et le vol en croisière subsonique, et des moyens pour désaccoupler les moyens (20) de transmission pour le vol en croisière supersonique.
