Book Description
ATMOSPHERE ENTRY TRAJECTORIES WERE STUDIED TO DETERMINE THE RANGE FOR TWO TYPES OF MANEUVERS. 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.

A Study of Synthesis Techniques for Optimal Controllers
Author: B. PaiewonskyPublisher:
ISBN:
Category : Automatic control
Languages : en
Pages : 204
Book Description
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.
