Abstract : Optimal intercept trajectories in one and two-dimensional situations are investigated. Target evasive maneuvers are not considered. Aerodynamic drag on the rocket is a function of rocket velocity and an exponential atmosphere. Trajectories, often including singular thrusting, are calculated for the one-dimensional case by digital computer using the final rocket velocity as a parameter. Newton-Raphson techniques are used, and prove sensitive to estimates of initial values. The boundary-value problem for the the two-dimensional situation is formulated, but the numerical solution diverged. The difficulty is apparently due to the of Newton-Raphson methods. (Author)
