- Description
- THIS IS NOT A REQUEST FOR QUOTES (RFQ) OR AN INVITATION FOR BID (IFB), NOR IS IT TO BE CONSTRUED AS A COMMITMENT BY THE GOVERNMENT. NASA/KSC plans to issue a Request for Quotation (RFQ) for a follow-on Research & Development (R & D) study ?Simulation Tool for Spacecraft Lateral Slosh Prediction Study?. The purpose of this study is to understand lateral slosh and to refine techniques for modeling slosh in general. A series of test, utilizing the Spinning Slosh Test Rig (SSTR), will expand NASA?s knowledge of slosh behavior as it is influenced by the presence of diaphragm type propellant management devices (PMDs). Particular emphasis will be placed on diaphragm shape stability for larger size tanks. Of particular interest in this effort is obtaining answers to the following questions: 1. Under launch level random vibrations and spin-up conditions, do larger scale (23?) diaphragms assume a preferred shape? 2. What are the sensitivities in natural frequency, response amplitude and damping to differing lateral acceleration load levels? 3. What are the differences in natural frequency, response amplitude and damping resulting from diaphragm shape variability? 4. Is there a different type of test that can be performed using the Spin Slosh Test Rig (SSTR) that will yield a richer set of information that is more compatible with the Parameter Estimation methods being developed at ERAU and KSC? This procurement is being conducted under Federal Acquisition Regulations Part 13, Simplified Acquisition. NASA/KSC intends to purchase these professional services from the Southwest Research Institute (SwRI), 6220 Culebra Road, San Antonio, TX 78238. This solicitation will be awarded in accordance with the authority of FAR 13.106-1(b), the acquisition of supplies or services determined to be reasonably availably from only one source. In accordance with FAR 13.106-1, a Justification for Other than Full and Open Competition is on file. The primary equipment needed for the testing involved in this study is unique, specialized, one-of-a-kind NASA owned equipment located at SwRI plant in San Antonio, Texas. The Spinning Slosh Test Rig (SSTR) is a large assembly, approximately 10?x10?x10? feet, with power and control wiring hard-wired throughout SwRI?s facility. Interested contractors would have to travel to SwRI to perform this testing, as the SSTR cannot be relocated without incurring significant shipping and labor (disassembly/assembly) costs estimated at $61K. SwRI has the unique expertise as the design agency, and developer of the SSTR. SwRI personnel are expert in the design, operation and test specific modification of the SSTR. This capability was recently demonstrated by SwRI in the SSTR modifications made to perform the Generic Centerline Tank Study. Another contractor would have to duplicate costs to the Government that would not be expected to be recovered through competition. Unacceptable delays in schedule would result due to another contractor having to duplicate the learning already achieved by SwRI. This notice of intent is not a request for competitive proposals. However, all interested organizations may submit their capabilities and qualifications to perform the effort in writing via e-mail or fax to Karim F. Hourani; FAX: 321-867-4848, E-MAIL: karim.f.hourani@nasa.gov not later than 3:30 p.m. local time (Eastern Standard Time) on November 26, 2007. Such capabilities/qualifications will be evaluated solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. A determination by the Government not to compete this proposed effort on a full and open competition basis, based upon responses to this notice is solely within the discretion of the government. Oral communications are not acceptable in response to this notice. An Ombudsman has been appointed. See Internet Note ?B?.
