Successful qualification firing test for Zefiro 23

02.04.2008
On 27 March 2008, the second stage motor for Vega - Europe's new small launcher - successfully completed a static firing test at the Salto Di Quirra Inter-force Test Range in Sardinia, Italy.
Ignition of the qualification model of the Zefiro 23 solid-propellant rocket motor occurred at 13:15 CET. In just 14 seconds, the thrust reached 930 kN, equivalent to nearly 95 tonnes of force.

This was the second and final firing test for the Zefiro 23, in which over 24 tonnes of propellant was consumed with a flame temperature of over 3000 K. The burn lasted approximately 75 seconds and initial results show the test to be a success.

Performance as predicted

The combustion chamber pressure and motor thrust were well within the test prediction. Large amplitude movements of the thrust vector control system were executed - simulating worst-case manoeuvres - and the performance was very satisfactory. Additionally, modifications implemented in the nozzle design following the anomaly experienced during the previous Zefiro 9 test were proven to be effective.

“The success of this test demonstrates the soundness of the design and rewards the enormous efforts of the team that has worked on the project,” stated Francesco Betti, Head of the Design Department at Avio's Space Division.

The motor will now be transported back to Avio's facility at Colleferro (Italy) for a thorough inspection of all its components and the data obtained from the 400 sensors deployed during the test will be analysed in more detail.

“The project team will rendezvous at Salto Di Quirra in June for the Zefiro 9 firing test,” announced Paolo Bellomi, Technical Director of ELV, the Vega launcher prime contractor.

Two motors now qualified

In the past 27 months, four Vega test firings have taken place at Salto Di Quirra, each one a milestone in the development of the Vega launcher. The Zefiro 23 is the second Vega solid rocket motor to achieve qualification, following the P80 first stage motor, which completed qualification testing in December 2007.

“The teams of Avio, ELV, SABCA APP and of the Integrated Programme Team of ESA, CNES and ASI did a great job. This success paves the way for the Vega maiden flight,” said Stefano Bianchi, Head of the Vega Programme at ESA.


About Vega

Vega is a single body launcher composed of three solid-propellant stages and a liquid-propellant upper module. It is approximately 30 metres high, and weighs a total of 137 tonnes at lift off. Vega's reference launch capacity is to carry a 1500 kg payload into a 700 km-altitude polar orbit, but the launcher is also designed to serve a wide range of scientific and Earth observation missions.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
