description abstract	Description of Driving Event: To meet Space Shuttle launch requirements, the proportion of dissolved air in the Orbiter's hydraulic fluid must be below 1 volume percent. Early in the Shuttle program, the deaeration system that removed the dissolved air from the hydraulic fluid was found to be unreliable and could not meet this requirement. A greater proportion of dissolved air could lead to pump cavitation and excessive softness in hydraulic-actuator force-versus-displacement characteristics.
