Almost
every spacecraft requires and active attitude stabilization and control
system during atmospheric entry to steer the vehicle, to prevent undesired
vehicle oscillations, to align the vehicle for terminal landing, and to
steer the vehicle along a flightpath where aerodynamic heating and load
limitations will not be exceeded.
The entry-control
system is closely coupled with the entry-guidance system, and should make
effective use of sensing, data processing, display, and control equipment
required for other mission phases, so that a minimum of additional equipment
and expendables is required for entry control. This document describes
in detail how to design entry control systems for all kinds of entry vehicles
that used aerodynamic forces for deceleration. It covers systems
to orient the vehicle for entry into the atmosphere and guide it to 100,000
ft altitude or deployment of the terminal-landing device.
Discusses
design and operation of the entry control systems used by Mercury, Gemini,
Apollo, X-15, ASSET, PRIME, and other important spacecraft. Includes
flight and mission experience analysis. Contains functional diagrams,
entry-control jet configurations, vehicle trim conditions, critical trajectories,
and other key engineering information.
