RV-Tの実フライトの極低温推進剤タンクに複合材タンクが使用されて空を飛んだ例としては世界初かつ原稿執筆時点（2018年８月）でも世界唯一であり、複合材タンク開発の大きな金字塔です。 0735名無しさん＠お腹いっぱい。2018/10/17(水) 18:32:48.76ID:tkUHtjy6>>733のソース it has developed carbon fiber composite tanks that are compatible with the liquid oxygen component.
SpaceX will have to launch at least half of its constellation of Ku- and Ka-band satellites within six years of today, per the agency’s recently revised rules, or its authorization freezes at the number of satellites in operation at that date. The FCC in September relaxed its deadline, giving operators nine years to launch their full constellation, but even those rules are stricter than what SpaceX would refer. The launch-provider-turned-satellite operator asked the FCC for an okay to launch 1,600 satellites in six years — just over a third of its full constellation.

Phantom Express will rely on advanced composite tanks holding the supercold Liquid Hydrogen fuel and Liquid Oxygen oxidizer consumed by the AR-22 engine on the plane’s business end.
ちなみに，耐熱システムもかなり充実している．
The hybrid composite-metallic wings and control surfaces for atmospheric flight will have to withstand temperatures over 1,100°C during the hypersonic flight regime and re-entry, using third-generation thermal protection systems. 0759名無しさん＠お腹いっぱい。2018/10/17(水) 20:14:49.16ID:RZH7SrMf>>758 ・ボーイングにそんなカネ無い。 ・DARPAは技術実証のみで、後始末はしない。 0760名無しさん＠お腹いっぱい。2018/10/17(水) 20:20:53.72ID:+lWAi6hg>>751 アレスもな。 それらのせいでアメリカは、時間と、お金と、威信と、自信を失ったよね。
ASAP member Don McErlean outlined several issues that SpaceX’s Crew Dragon spacecraft needs to overcome, including a lack of a final resolution on the root cause of the failure of a composite overwrapped pressure vessel (COPV) that led to the pad explosion of a Falcon 9 more than two years ago. That is linked, he added, to the use of “load-and-go” fueling of the rocket that would take place, on commercial crew missions, after astronauts have boarded the spacecraft.
The use of additive manufacturing is a key element in Aerojet’s updated version of the engine, the RL10C-X, intended to lower its cost without compromising reliability or performance. 0806名無しさん＠お腹いっぱい。2018/10/18(木) 00:59:33.10ID:8U9gnOEZ>>804 マーク 0807名無しさん＠お腹いっぱい。2018/10/18(木) 01:22:21.62ID:kw6JCZI+>>804 得意技とか意味の分からないことを喚かれても困るんだが… 大方お前が自分に批判的なのは同一人物だと勝手に思い込んでるだけだろうが
