The first full-scale model of the rocket motor that will propel Ariane 6 and Vega-C into orbit has been cast and filled with inert propellant for testing at Europe's Spaceport in French Guiana. The P120C is the largest solid-propellant rocket motor ever built in one segment.
Each P120C will hold over 140 tonnes of propellant in a carbon fibre casing almost 11.5 m long and about 3.4 m in diameter. It is derived from Vega's current first stage motor, the P80, which holds 88 tonnes of propellant.
The design builds on existing expertise and lessons learned with Vega's P80, and it increases Vega performance with Vega-C. Two or four P120Cs will be strapped onto Ariane 6 as boosters for liftoff.
The model casing, shipped this summer from Avio in Italy, took about 36 hours to fill with inert propellant blended at Europe's launch base in Kourou.
Using non-ignitable fluid that has a similar density to the real propellant meant that engineers could safely test all the new equipment and procedures.
Filled and sealed, the fluid in the casing could stabilise, cool and harden - the curing process - which took 10 days.
Further tests on the motor, now horizontal, will confirm that it is ready to be integrated with other structures in January.
These tests are a step towards casting active propellant in November with a P120C development motor that will be static fired in April.
Vega-C is expected to debut in mid-2019, increasing performance from Vega's current 1.5 t to about 2.2 t in a reference 700 km polar orbit.
Ariane 6's maiden flight is planned for 2020. This new launch vehicle will be gradually phased in to succeed Ariane 5.
Moscow (Sputnik) Oct 10, 2017
Russia may adjust its federal space program to facilitate funding of the construction of a super-heavy-lift launch vehicle (SHLLV), General Director of Russia's Rocket and Space Corporation Energia Vladimir Solntsev told Sputnik on Tuesday. Solntsev said that Energia is jointly working with Roscosmos "on proposals to amend the federal space program" to get the necessary funding for the pro ... read more
