Status of the Advanced Reusable Technologies Project

Abstract

The Advanced Reusable Technologies (ART) Project, part of the Advanced Space Transportation Program Office at the NASA's Marshall Space Flight Center in Huntsville, Ala., focuses on future reusable technologies beyond those being pursued by X-33. The prime objective of the project is to dramatically reduce the cost of access to space. In April 1996, an NRA was issued soliciting proposals for tasks focusing on rocket-based combined cycle propulsion system (RBCC). In August of 1996, five contractors were selected for a two year period to design and ground test their RBCC engine concepts. The work on these contracts should be completed by the end of this year. In March of this year, another NRA was issued to solicit inputs for reusable vehicle and propulsion technologies applicable to earth-to-orbit and in-space transportation. The current RBCC effort is the first of three phases leading to a large scale flight demonstrations of the technology for space launch vehicle propulsion. This first phase will provide initial verification of proposed concepts through ground demonstration of combined rocket/air breathing propulsion technologies. Using the most promising concepts identified in the first phase, the second phase will design, manufacture and ground test flight-type engine(s) to demonstrate actual design weights and performance. In the third phase, the first flight of a sub-scale integrated X-vehicle is planned for 2002. This paper describes the current status, plans and progress of the ART Project.
