The invention provides a common-bottom storage tank propelling system applied to a spacecraft. The common-bottom storage tank propelling system comprises a parallel cross gas path system, a cross supply liquid path system, a double-layer common-bottom storage tank, a pressure supplementing and releasing system of the double-layer common-bottom storage tank and a surplus measuring system. The parallel cross gas path system is used for realizing gas path cross supply to the double-layer common-bottom storage tank; the double-layer common-bottom storage box supplies liquid path propellants to the engine in a cross mode through the cross supply liquid path system. The pressure supplementing and releasing system is used for adjusting the common-bottom pressure difference and the absolute pressure of the double-layer common-bottom storage tank; and the residual amount measuring system is used for measuring the residual amount of the in-orbit propellant. The double-layer common-bottom storage box is adopted and serves as a force bearing structural part, the space layout is fully utilized, and the use safety is high; the reliability and safety of on-orbit use of the common-bottom storage tank are controlled in a system self-feedback adjusting mode, and meanwhile the system has the functions of gas-liquid path main and backup multiple switching, fault isolation and system reconfiguration.
