Abstract
L'invention concerne un moteur combiné cyclique (10) comprenant une section de compresseur et une section de turbine (14, 18), ainsi qu'au moins un dispositif de flux non dérivé (16) fournissant une entrée d'énergie dans la section de turbine (18). La section de compresseur (14) comprime l'air selon un taux de compression PR¿gt?. Le dispositif de flux dérivé (16) comprime également l'air selon un taux de compression volumétrique R¿vc?, PR¿gt? x R¿vc? étant sélectionné, selon un mode de réalisation de l'invention, pour fournir un cycle permettant d'obtenir un moteur combiné cyclique plus compact et léger.
