Based on the calculation theory of StandardBookkeepingMethod (SBM)，the possibility and limitations of SBM using in TPS wind tunnel test was analyzed. For high fan nozzle pressure ratio situation, the flow in the fan nozzle exit plane is always at choked condition. The mass flow ratio and thrust force calculation are independent of the static pressure of the flow at the nozzle exit plane. SBM is suitable for this condition. For lower fan nozzle pressure ratio power setting condition, the flow in the fan nozzle exit plane is subsonic. The mass flow and thrust are a function of the static pressure in the exit plane Pe. And SBM calculated by assuming that Pe is equal to the static pressure of free stream P0. The error introduced by the difference between Pe and P0 could not be neglected for lower fan nozzle pressure ratio situation. The error of the mass flow and thrust caused by static pressure in the exit plane were gave out in this paper. It’s strongly recommended to measure the static pressure in the nozzle exit plane for TPS wind tunnel test.
