NASA Space Launch System Structural Test Stand
GMC was retained by NASA to provide various architectural and engineering services for the Space Launch System (SLS) Test Stand facility in Huntsville, Alabama. The project included the design development and construction documents for TS4693 for the LH2 tank and forward skirt test stand. The stands were used to test the largest cryogenic fuel tanks ever used on a rocket to ensure that the huge structures can withstand the incredible stresses the skyscraper-size vehicle will experience during launch. The design package incorporates sustainable design principles to reduce life cycle costs, minimize the impact on natural resources and maximize occupant health safety and productivity to the largest extent possible. The overall footprint of the “Two Towers” test stand is 92’-6”x 48’-0” and is comprised of two 48’-0”x 20’-0” wide sections of platforms on either side of a 48’-0”x 48’-0” clear area. Platforms have been provided at approximately 10’-0” on center for the full height of the test stand in order to provide access to the article and to allow for loads to be applied at virtually any elevation. The frame is 212’-0” high at the top of the “roof” level framing (i.e., the highest level of framing). A roof over the article is steel framing is designed to tie the two towers together at the top. Raising and lowering of the load deck was accomplished using external cranes, thereby ensuring some modularity for the test stand concept, while a single permanent hoist helped raise the article into place, although the exact means of inserting the article into the frame is to be determined. Site work has been designed assuming that the test article has been “backed in” to the frame, in lieu of the “drive-thru” concept.
