Delta Interim Upper Stage System Study. Volume I. Executive Summary.
Abstract
This study provides DOD with the preliminary design of a Delta IUS system, the identification of IUS/Orbiter and IUS/Spacecraft interfaces, and Delta IUS program definition and costs. The study has shown that with the addition of two inexpensive propellant tanks and other minor stage changes, the basic Delta stage can be easily converted into an IUS stage that can capture all of the DOD and NASA earth orbital missions with ample performance margin (4,820 lb to synchronous orbit). Furthermore, the addition of simple, low-cost auxiliary stages based on existing solid propellant motors, the Delta IUS can capture all of the NASA planetary missions specified. The combinations of IUS elements proposed - the Tri-Tank Family approach - provides the flexibility to select the least expensive IUS suitable for the mission, thus enhancing cost effectiveness.
