The pressurized propulsion section to the right of axis a is divided into a gradient pressurized propulsion section G3 and a gradient pressurized propulsion section G5.
The gradient pressurizing propulsion sections on the left side and the right side of the central axis A are respectively and symmetrically arranged.
