Abstract

A multiple-flow turbojet with adjustable bypass ratio comprising a low pressure spool and a high pressure spool casing. Aerodynamic surfaces mechanically integral with the high pressure spool are disposed in a cold secondary flow whose characteristics vary as a function of the setting of a guide means and cause a variation in the bypass ratio.
