The component characteristics test study of a missile model with complexity configuration in high speed wind tunnel

The component characteristics test of the missile model was conducted in the FL-28 wind tunnel.The missile’s configuration is complicated.The angels of attack ranged from-6°to 10°,and angels of sideslip were from-6°to 6°.Protective cover,left wing and rectifier covers were involved in the test.A 5-component balance was used to obtain force and moment data of protective cover,and the component characteristics was acquired when the test data were correc-ted by the result of pressure measurement of the aperture.Three 3-component balances were used directly to obtain component characteristics data of left wing and rectifier covers.The test result can be applied for structure design of those components.The correction method for the da-ta of protective cover is verified,and it could provide some experience for the later tests.
