I wanna see video of it as it climbs out and pitches over to launch azimuth, though not much may show through the intense yellow-white flames. I see Russians tsking and shaking their heads over not using toroid kero tank in the second stage and nesting the engine inside it, to cut down on the big interstage, and for not using struts there. But I suppose the toroid tank is complicated to make and AlLi/composite materials make up for weight gain. --Damon |

But I suppose the toroid tank is complicated to make and AlLi/composite materials make up for weight gain. It looks like a Zenit sitting on the engine module of a Tsiklon. The reason for all the truss interstage girders on the Russian boosters is to allow the upper stage to ignite while the stage below it is still firing, thereby eliminating the need for ullage motors to seat the propellants. The gas from the upper stage engines exits through the gaps in the truss until the lower stage shuts down and separates. We used the same technique on the Titan II ICBM, which is why it has holes between the two stages. The one that looked really Russian is the Ares 1, which strongly resembles the core and upper stages of the Soyuz booster: http://esamultimedia.esa.int/images/...2A_08182_H.jpg ....right down to having the truss girders between the stages in some of the early iterations (see third from left): http://upload.wikimedia.org/wikipedi..._Evolution.jpg The jettisonable aerodynamic shroud over the Orion CM on the newer versions strengthens the resemblance even more.
