| الوصف: | The aerodynamic coefficients of the M483A1 have been refined based on analysis of 65 BRL Transonic Range tests. Both the original M483A1 tests (1975) and the latest tests from 1987-1989 were analyzed utilizing a six degree-of- freedom technique during September-October 1990. The Magnus moment was found to be extremely nonlinear with angle of attack and Mach number. The size of the slow arm limit cycle was computed along the region of dynamic instability due to a large positive Magnus moment at moderate yaw levels. The values of the axial force, normal force, pitching moment, damping moment, and Magnus moment are presented. |
