The Vinci from Arianespace is a Satellite Launch Vehicle Engine with a vacuum thrust of 130-180 kN. It has a specific impulse of 457.2-458.2 s and a combustion pressure of 45-60 bar. This engine has a mixing ratio of 5.5-6.1 and a nozzle outlet diameter of 1.84 m. It has a TPH rotation speed of 70,000-90,000 rpm and a TPO rotation speed of 14,000-18,000 rpm. The Vinci engine is reignitable in light and intended for the new upper stage of the Ariane 6 launcher and uses LOX - LH2 as its propellant. It represents the latest generation of cryogenic upper-stage engines for space launchers and is designed to be simple to build and operate. This cryogenic launcher has a propellant flow rate of 24.20-34.11 Kg/sec and is ideal for space launchers.
