Description
The use of premium mechanical properties for materials, in lieu of minimum guaranteed properties, will result in substantial weight and overall Shuttle program cost savings. To obtain materials with premium mechanical properties (properties that exceed present minimum guaranteed values) will require negotiation with the material suppliers; the prime objective is to obtain the highest supplier guaranteed mechanical properties at an acceptable additional raw material cost. To illustrate the potential benefits of typical properties a study involving a Space Shuttle orbiter wing resulted in a total program cost reduction of $39.3 million, and a weight saving of 1414 Ibs. Suggested means of quality control, inspection and controlled in plant use of premium materials are covered.
