Some Planar Motions of Symmetric Bomblets and Magnus Rotors.

Abstract

Linearized equations of motion are derived for small perturbations of a symmetric bomblet about a steady glide. The large yaw equations apply to motions where the spin axis is nominally horizontal and normal to the velocity vector. Use of the symmetry with complex variables is made to reduce the order of the system. Parameters of the resulting sinusoidal motions were related to the coefficients of the differential system in order to obtain aerodynamic coefficients from observed free flight data. The theory is restricted to those applications in which the missile longitudinal velocity remains small in comparison to the velocities along the other two axes and the motion takes place in an essentially vertical plane with the roll rate constant.
