Badanie teoretyczne własności dynamicznych lotu obiektów zrzucanych z samolotu

The paper deals with the dynamics of a freely falling slender body, equiped with control surfaces, body with deflected height control surfaces, and body with the rocket type braking-accelerating unit. The object is concerned as a rigid body with three degrees of freedom. The obtained system of strongly non-linear, ordinary, second order differential equations is solved numerically under prescribed initial conditions. Using the method of freezed coefficients and the perturbation method the stability analysis was reduced to finding the eigenvalues and eigenvectors. Aerodynamical characteristics were obtained as a result of model testing in a wind tunnel.
