For one type range was controlled principally by varying the point in the trajectory where the lift-drag ratio was reduced to maximum negative lift-drag ratio. For the other maneuver range was controlled principally by varying the value to which the lift-drag ratio was reduced. The influence on range of maximum deceleration limit and an error in lift-drag ratio were included; the convective and radative heating to the stagnation point of the spacecraft were also studied. The analysis was made for a spacecraft with a maximum lift-drag ratio of 0.5 entering the earth's atmosphere at parabolic velocity. The results for both types of maneuvers indicate that the spacecraft aerodynamics can provide range up to global range.

Available in PDF, EPUB and Kindle. Book excerpt: This report is organized as follows. A general discussion of optimal control precedes a section devoted to the mathe matical aspects of optimization. Stochastic problems are taken up next and this is followed by a section on two-point boundary problems. In many cases the main problem is to find an extreme value of a function of several variables. There is a section describing methods for doing this. The sections on synthesis procedures, computational studies and conclusions complete the main portion of the report.

This book was released on 1961 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study has been made of a method for controlling the trajectory of a high-drag low-lift entry vehicle to a desired longitude and latitude on the surface of a rotating earth. By use of this control technique the vehicle can be guided to the desired point when the present position and heading of the vehicle are known and the desired longitude and latitude are specified. The present study makes use of a single reference trajectory and an estimate of the lift and side-force capabilities of the vehicle. This information is stored in a control-logic system and used with linear control equations to guide the vehicle to the desired destination. Results are presented of a number of trajectory studies which describe the operation of the control system and illustrate its ability to control the vehicle trajectory to the desired landing area.
