AbstractThe methodology and results of development of the numerical model describing dynamic state of objects externally attached to the wing are submitted. The aircraft impact with a landing strip due to emergency landing is considered. The problem of transitional interaction is solved using finite element method, on basis of which the model of an aircraft carrying externally attached objects is developed. Time dependences of displacements, velocities and accelerations for different points of the objects are obtained.
