Doesn't a lot of the structural strength derived from the vertically stacked skin and whatever structural elements that are arrayed around the tanks? After all, the majority of mass in the center is literally quite fluid! Were there ever any rockets build that used multiple tanks arrayed around a skeletal core? Can't think of any. Can't think of a reason why that would be advantageous either! Hence the exo-skeletal model will always win over the skeletal model?! Opinions? Hence: Roaches Conquer Space! Dave It is generally the case that the propellant tank skin supports the thrust loads for orbital rockets, often with vertical stringers, or longerons, arrayed internally in the tanks to help support the axial loads. However, I found an image of a proposed design of the Altair lunar lander that shows such a skeletal support strutu http://www.parabolicarc.com/2009/03/...roposal-altair...

Or if google really has competitors for street view compilations. Google uses a variety of vehicles for street view; I've seen something in the Focus/Yaris size range, with either a fancy paint job or vinyl skins in garish green, hyping the Googleness Of It All. Some of the "Google Street View Finds" in various web loggia have part of the camera car in view (directly, like Curiosity filming its fender), the shadow of the car, or a reflection of the car. (Why sci.astro? Hubble doesn't use skeletal tank frames) /dps -- Who, me? And what lacuna? |

And this "octagonal" configuration will still have an engine in the middle no? Or will it just be a ring around the perimeter? It will almost certainly need an engine in the center, otherwise I'd imagine exhaust gas recirculation into the gap left by an absent center engine would be a problem. With an octagonal configuration and nine engines, the ninth engine must necessarily be either inside or outside the octagon.
