| Space Shuttle Orbiter
A verbose index is available for this
- Thermal Protection System
- Various materials applied to the outer structure protect the orbiter
from excessive heat.
Main Propulsion System
- Along with SRBs, provides velocity increment necessary to reach
Orbiter/External Tank Separation System
- Includes system components on both sides of the separation.
Orbital Maneuvering System
- The orbital maneuvering system provides the thrust for orbit insertion,
circularization, orbit transfer, rendezvous, and deorbit.
Reaction Control System
- The RCS units provide the thrust for pitch, yaw and roll maneuvers
and for small velocity changes along the orbiter axis.
Electrical Power System
- EPS subsystems work together to provide electrical power to the
vehicle during all mission phases.
Environmental Control and Life Support System
- ECLSS systems interact to provide a habitable environment for the
flight crew and cooling or heating for various orbiter systems and
Auxiliary Power Units
- The orbiter has three APUs, hydrazine-fueled, turbine driven power
units produce pressure for the vehicle's hydraulic systems.
Water Spray Boilers
- The water spray boiler system consists of three identical independent
water spray boilers, one per corresponding auxiliary power unit and
- The hydraulic system consists of three independent systems, each
providing mechanical shaft power to drive a hydraulic pump.
Landing Gear System
- Each landing gear includes a shock strut with two wheel and tire
Caution and Warning System
- Designed to provide the crew with both visual and aural cues when
a system exceeds predefined operating limits.
- Ground-based, orbiter and satellite systems are employed to keep
the crew in touch with Mission Control.
- Controls, or assists in controlling, most of the shuttle systems.
