Fully loaded with solid fuel, the P120C rocket motor common to Europe’s future launchers Vega-C and Ariane 6, held vertically in the test stand, awaits its first hot firing on 15 July 2018. Sensors will gather about 600 measures during the test.
The P120C is 13.5 m long and 3.4 m in diameter, contains 142 tonnes of solid propellant and provides a maximum thrust of 4615 kN (in vacuum) over a burn time of about 135 s. It is the largest-ever solid rocket motor built in one piece
The design builds on existing expertise and lessons learned with Vega’s P80 first stage motor. P120C will replace P80 as the first stage motor of Vega-C. Two or four P120Cs will be strapped onto Ariane 6 as boosters for liftoff.
