| Abstract: | The lifesaving whim system is an asymmetric-mounted external hanging device,mounting of which will bring about asymmetric aerodynamic forces and moments,thus affect the helicopter's aerodynamic characteristics,and control and stability.Through wind-tunnel tests,the longitudinal and lateral aerodynamic force and moment characteristics and static stabilities are compared with them after mounting of the lifesaving system in terms of different angle-of-attacks,sideslip angles and wind speeds,and finally the effects of the lifesaving whim system on helicopter's aerodynamic characteristics,and control and stability are determined. |
