Abstract : A slide rule is described, which allows the determination of the trajectory data of a free flying body at a time t + delta t starting at the values at the time t and the resistance of the surrounding medium, disregarding the lift. The drag function E = Ma cw rho aoF/2G constitutes an essential basis for the computation procedure. The integration of the system of differential equations leads to a logarithmic function, suggesting a reproduction of the occurring values on the scales of a slide rule. (Author)
