本次任务使用的新整流罩,复材成型无需高温处理,无金属接头
The Vega fairing shell on the right is made using out-of-autoclave technology and has no metallic joints compared to the heritage version on the left.

《RUAG payload fairing debuts on Vega rocket》
http://www.compositesworld.com/news/ruag-payload-fairing-debuts-on-vega-rocket-
On August 1, Vega flight VV10 started from the launch pad in Kourou. On the top of the rocket, protecting the two satellites, debuted a RUAG (Zurich, Switzerland) Space payload fairing, which was manufactured out-of-autoclave. This advanced process was now for the first time applied to the payload fairing of a Vega rocket – after having succeeded initially on an Ariane 5 about five weeks ago. The new procedure reduces both throughput time and cost – thereby allowing for a higher delivery volume and flexibility.

Peter Guggenbach, CEO of RUAG Space, commented: “The out-of-autoclave process is very advanced, as it responds to the needs of today’s space industry. Shorter lead times, less cost, flexible adjustments and higher delivery sequence – this is our contribution to make access to space more affordable.”

In order to run it, RUAG has invested in a state-of-the-art manufacturing hall in Emmen, Switzerland. Relying on tailor-made machinery and automated processes, the new composite center was inaugurated in 2016.

The carbon-fiber based payload fairing consists of two half-shells, which separate in space. These shells are newly cured in an industrial oven instead of an autoclave. This requires less energy, and – thanks to its size – the industrial oven can cure an entire half-shell in one piece. The costly and time-consuming vertical integration of individual shell elements can be avoided. Overall, the Vega payload fairing is 7.8 meter high, and has a diameter of 2.6 meter at its largest point. Due to the out-of-autoclave manufacturing approach the fairing is around 70 kg lighter as the original fairing, cured in an autoclave.

免去了高温处理这一步,尺寸就不再受限了,可以整体成型。
