Line Replaceable Unit (LRU) Analysis in the Space Shuttle Orbiter Electrical Power System

The National Aeronautics and Space Administration (NASA) Space Shuttle orbiter, as a test bed for low-orbit space laboratory experiments, needs an orbiter voltage analysis on all orbiter line replaceable units (LRU´s). This analysis should use a mathematical model to predict voltages at the various LRU´s so that voltage drops from a bus to an LRU can then be computed based on calculated resistance of the conductors and load current.
