Description
The passive External Tank(ET) is a very active ingredient in the overall Shuttle performance improvement program. Currently, the ET is successfully achieving a 6000 pound weight savings program with the first Lightweight Tank scheduled for delivery in June 1982. Weight savings are being accomplished by: 1) an unique approach to factor of safety, 2) design optimization and 3) reducing large margins. Future performance improvements include studies that develop: 1) an improved Thermal Protection System (TPS) for the aft dome, 2) improved propel 1 ant management, 3) potential use of composites, 4) use internal wiring to eliminate the cable trays, and 5) elimination of the slosh baffle in the L02 Tank depending upon the results from the DDT&E flight test program. All of the ET performance improvements are compared and selected on the basis of non - recurring and recurring costs and technical risk.
