The T-tail configuration in civil aircraft can reduce downwash and speed inhibition at the horizontal tail,and has higher efficiency.However,this configuration also leads to can constitute a serious asymmetric load situa-tion on the vertical tail.This paper proposes a theoretical calculation formula for the horizontal tail lift under side-slip conditions about T-tail aircraft,obtaining an equation describing the variation of the horizontal tail lift with sideslip angle.Subsequently,the CFD method is employed to simulate and analyze the asymmetric load on the T-tail under crossflow,verifying the accuracy of the proposed calculation formula.Furthermore,by combining the theoretical calculation equation with the results of CFD flow field simulation of the whole aircraft,the impact of dif-ferent variables on the asymmetric load of the T-tail is determined,providing a basis for the design of asymmetric load for T-tail aircraft.
