After seeing the design of the transport spacecraft, Jiang Chen almost laughed out loud.
These Russians just changed the rocket in the middle, lined up four rockets together, then removed the third-stage rocket. They placed the fuel tank at the bottom of the middle section of the spacecraft while the cargo was above. Although the overall layout surpassed the standards of the times, the power system still used the original chemical fuel engine.
The advantage of this cuboid aircraft was the longitudinal acceleration which could effectively alleviate the load on the aircraft's outer casing during the acceleration phase. But at the same time, a problem also arose in which if the spacecraft wanted to turn a corner in space, it would be extremely difficult. It'd be like holding a toothpick, sticking to the wall, it'd be hard to break the toothpick, but it wouldn't take much effort to break it by pinching the two ends.
