Snecma Contributes to Successful Launch of Ariane 5 ECA

18 February 2005

The successful launch of Ariane 5 ECA on February 12 is a major milestone for the European space industry, and especially for the Snecma group.

Snecma Propulsion Solide was just one of five group companies which made major contributions to the success of Flight 164.

Snecma Propulsion Solide designs and manufactures the nozzles for the MPS solid rocket motors. Each nozzle is made of three tons of carbon composite and phenolic silicon materials to stand up to temperatures reaching 3,000°C. The nozzle is also fitted with a flex-bearing so it can be swiveled to steer the launcher for the first two minutes of flight.

The other companies involved were Snecma Moteurs, which conducted the Vulcain 2 engine modification program in conjunction with EADS ST in Germany and Volvo Aero in Sweden. Techspace Aero, Europropulsion, and Techlam also made telling contributions.
