The second ignition test of the Zefiro-40 engine of the European Vega-C launcher was also successful, in the new version that is defined with an improved nozzle design: Avio tested it at the Salto di Quirra inter-force testing facility to qualify it for a return to flight by the end of 2024, after the stop due to the failure of its second launch in December 2022. This was announced by the European Space Agency.
This second firing test follows the first one performed last May and concludes the qualification tests for the new Zefiro-40 design, which is used to launch satellites into space.
“Engineers are analysing the motor’s performance, with the initial post-test review indicating that the new nozzle assembly and motor performed as expected,” ESA wrote in a statement. “While the first test in May was performed at high operating pressure and with a short burn time, today’s test was conducted at low operating pressure and burned for longer, as expected and in accordance with the test predictions. The two burns are a standard procedure when preparing solid rocket motors for operations, enabling Vega-C to be launched by the end of 2024.”
The Zefiro-40 is a 7.6-meter-tall rocket engine loaded with over 36 tons of solid propellant. For this test, the engine was installed on a horizontal test stand.
Vega-C is the largest evolution of the Vega rocket family. The original Vega was launched in 2012 and has flown 22 times. The last flight was on 4 September for the launch of the third Sentinel 2 satellite. Vega-C is set to take its place, giving Europe independent access to space, together with the Ariane rocket family, to launch any satellite into orbit.
