法德趋向于阿丽亚娜6火箭使用固体发动机

美国航空周刊报道，法国和德国研究了三种可能的构型。它们都是在最上级
使用液氢液氧发动机，在第一级的助推器使用固体发动机。但是在第一和第二主发动机上，两种使用全固体，一种使用液氢液氧。
文章提到目前阿丽亚娜火箭不堪成本太高，政府补贴太昂贵，日本的h2运载火箭也是同样问题，但是美国的spacex的煤油液氧发动机成本就低了。

If things had gone according to plan, Europe would be flying a more powerful and efficient version of its Ariane 5 rocket today, one that could compete in the commercial market without public subsidies, and development of a next-generation launcher would be well underway.

Instead, the Ariane 5 suffered a serious failure in 2002 that slowed plans to boost its performance and shelved what were mostly French ambitions to start work on a less costly successor.

An evolution of the Ariane 5 ECA that now delivers roughly half of the world's communication satellites to orbit each year, the enhanced Ariane 5 ECB would have entered service in 2006. But it was 2008 before the European Space Agency (ESA) approved low-level funding for early development.
