A STUDY OF TIME-OPTIMAL INTERCEPT IN TWO DIMENSIONS (VOL 2)
Abstract
A planar time-optimal formulation is used to study the terminal phase of interception above the atmosphere in a uniform gravitational field. The dependence on initial conditions of the optimal steering angle is examined for initial relative velocities ranging from 5,000 ft/sec to 50,000 ft/sec and initial distances up to 500,000 ft. Results are presented in graphical form for two typical rockets showing: (1) the range dependence of terminal error sensitivities to errors in measurements of initial conditions taken along the initial rectilinear coasting path and (2) the variation in these terminal error coefficients along optimal interception paths. Some interceptions with proportional control systems were made and compared with the optimal paths.
