The aerodynamic shape for airborne Electric-Optic(EO) turret has great impact on the aerodynamic characteristics of the plane,the precision of rotation of turret itself and the measurement results of the system performance.An optimal scheme for aerodynamic shape design is presented from the viewpoint of engineering practice.Based on the analysis to aerodynamic shape and aerodynamic characteristics, we proposed several possible aerodynamic shapes,among which an optimal design of turret was obtained through theoretical analysis and CFD simulation experiments.In addition,the application of the proposed method in practice was demonstrated by taking a certain type of helicopter airborne EO turret as an example.
