The self-generated pressurizing scheme of the liquid rocket uses a high-temperature pressurizing medium led out by an engine to pressurize the storage tank, and the self-generated pressurizing pipeline bears the main function of conveying the pressurizing medium to the storage tank. The autogenous pressurizing pipeline of the existing carrier rocket mostly adopts the layout form of branch pipes, multiple channels and a collecting pipe, and pressurizing mediums generated by an engine are collected through multiple channels so as to realize the conveying of the pressurizing mediums required by the storage tank.
The novel high-thrust carrier rocket adopts the structure layout that more than seven engines are connected in parallel, and the great increase of the number of the engines leads to more limited space in the engine cabin of the novel high-thrust carrier rocket compared with the traditional model.

On the one hand, the traditional autogenous pressurizing pipeline layout form is difficult to meet the limit of a limited space and the requirement of compensation quantity under the high-temperature high-pressure large-deformation condition; on the other hand, the increase of the number of engines causes the increase of the flow rate and pressure pulsation of the pressurizing medium in the self-generating pressurizing pipeline, and the balance is poor.
