Configuration of cargo air brake cabin of spacecraft

The invention provides a configuration of a cargo air brake cabin of a spacecraft. The configuration of the cargo air brake cabin comprises a cargo air brake cabin column segment, a cargo air brake cabin front-end face, a cargo air brake cabin column back ball, an outer cabin door and an inner cabin door, wherein the cargo air brake cabin column segment forms a closed cylindrical space, the outer cabin door is arranged on the ground-facing side of the cargo air brake cabin column segment, and the inner cabin door is arranged on the cargo air brake cabin front-end face. The inner cabin door after being opened communicates with a sealed cabin so as to form a first load transfer channel, and a load transfer mechanism can extend to the sealed cabin through the first load transfer channel. The inner cabin door and the outer cabin door cannot be opened at the same time. The configuration of the cargo air brake cabin of the spacecraft can automatically transfer large and small cargos into and out of the sealed cabin
