- THIS NOTICE CONSTITUTES AMENDMENT NO. 002 TO THE COMBINED SYNOPSIS/RFQ FOR ADVANCEDSPIN SLOSH TEST AND DATA ANALYSIS METHODS. Companies shall acknowledge all amendment(s)in their quote. This notice serves as the official amendment to subject synopsis/RFQ anda written amendment will not be issued.The purpose of this amendment is to make the following changes: (1) Change the SecondaryPoint of Contact to Jacklyn L. Norman; (2) Adjust the RFQ final date for questions from8/18/2011 to 8/19/2011; (3) Notify potential offerors of the 8/18/11 posting of theMicrosoft Word version of the Statement of Work with the synopsis/solicitation; and (4)Respond to the following two questions that were submitted for this RFQ.Question 1: What were the scientific/study motivations for selecting the STEREO tanksimulator (16.5 diameter) rather than the DI/PNH tank simulator (~23.125 diameter) asthe test article for the requested study project?Answer 1: The STEREO tank simulator is of a size more representative of the flight tanksused in spinning spacecraft with off-axis mounted tanks. The 23.125' DI/PNH tanksimulator is larger than most off-axis multiple-tank spacecraft configurations. [End ofAnswer]Question 2: Have other researchers conducted research with rigid diaphragm models(intended to mimic the behavior of a metallic diaphragm)? If so, how has the shape as afunction of fill level been determined in developing the models to be used in testingrigid diaphragms? Can you provide a description of the shape expected to berepresentative of metal diaphragms at the requested 30%, 60%, and 90% fill levels?Answer 2: Other researchers are currently working on rigid diaphragm slosh behavior. Mr. Brain Lenahen of Embry Riddle Aeronautical University (ERAU), a student of Dr. SathyaGangadharan mentioned in task 3.8 of the SOW, is building test articles to mimic rigiddiaphragms. Mr. Lenahen is working under a NASA LSP Graduate Student Fellowship for thisresearch. He is using NC machined foam forms and laying up fiberglass over them to makethe shapes. The fiberglass 'diaphragms' are then fitted into the test tank in place of anormal, flexible diaphragm. A different fiberglass diaphragm is required for each filllevel.The shape we are most interested in is the 'crater' shape since most metallicdiaphragms are constructed to collapse in the form of a symmetrical crater at all filllevels. Coordination between contractor, ERAU, and NASA during the design phase of themetallic diaphragm test task will be encouraged and facilitated. [End of Answer]The due date for receipt of offers is not extended.Companies shall provide the information stated in the synopsis/RFQ posted on the NASAAcquisition Internet Service (NAIS) on 8/11/11. Documents related to this procurement areavailable over the Internet. These documents reside on a World Wide Web (WWW) serverwhich may be accessed using a WWW browser application.
