[Mathematical modeling of the kinematics of a pilot's head while catapulting into an air stream]. / Matematicheskoe modelirovanie kinematiki golovy letchika pri katapul'tirovanii v vozdushnyi potok.

The trajectories of head movements in the helmet and velocities of impact contact with the seat and anterior of the cockpit were calculated as applied to every stage of the catapulting process and mass-inertia parameters of helmets taken into account. Kinematic models were used to describe biomechanic parameters of the head-neck system. Special attention was given to the case of catapulting to the air flow. The effect upon the nod of aerodynamic forces acting on the human body and the catapult ejection seat at air flow velocities of 700-800 and 1300 km/hr was calculated.

[Mathematical modeling of the kinematic reaction of the human body to impact accelerations]. / Matematicheskoe modelirovanie kinematicheskoi reaktsii tela cheloveka na udarnye vozdeistviia.

This paper considers the problem of selecting the structure of a mathematical model that describes the kinematic reactions of the human body during traffic accidents. The paper presents a calculation procedure and a program that allow selection of a structure (up to 17 elements) without deriving repeatedly equations of motion as well as automatic recalculation of all inertia and size parameters.
