ZONA Technology, Inc (ZONA) and Arizona State University (ASU) propose a R&D effort to develop a ground flutter testing system without wind tunnel, called the Dry Wind Tunnel (DWT) system. The DWT system consists of a ground vibration test (GVT) hardware system and a real-time unsteady aerodynamic force generation software developed from an aerodynamic reduced order model (ROM). The ground flutter test using the DWT system operates on the real structural model, thereby no scale-down structural model is involved. Furthermore, the impact of the structural nonlinearities on the aeroelastic stability can be automatically included. Moreover, the aeroservoelastic characteristics of the aircraft can be easily measured by simply including the flight control system in the loop. In addition, the unsteady aerodynamics generated computationally is interference-free from the wind tunnel walls. Finally, the DWT can be conveniently and inexpensively carried out as a post GVT test with the same hardware. In Phase I, we will validate this DWT concept on a rectangular flat plate with a reference flutter solution. Through this validation process, the most significant hardware issues will be resolved to pave the way for a successful Phase II validation on a complex structure, such as a real aircraft.

Global Earthquake Hazard Frequency and Distribution is a 2.5 minute grid utilizing Advanced National Seismic System (ANSS) Earthquake Catalog data of actual earthquake events exceeding 4.5 on the Richter scale during the time period 1976 through 2002. To produce the final output, the frequency of an earthquake hazard is calculated for each grid cell, and the resulting grid cells are then classified into deciles (10 classes consisting of an approxiamately equal number of grid cells). The greater the grid cell value in the final output, the higher the relative frequency of hazard posed by earthquakes. This dataset is the result of collaboration among the Columbia University Center for Hazards and Risk Research (CHRR) and Columbia University Center for International Earth Science Information Network (CIESIN).

<p>The purpose of this project is to develop state-of-the-art, green precision cleaning technologies for NASA&rsquo;s 21<sup>st</sup> Century Launch Complex thus eliminating long-term environmental costs to the Program.&nbsp; Precision cleaning is of critical importance in the aerospace industry.&nbsp; Failure to clean to specified levels may result in problems ranging from impaired performance to catastrophic failure.&nbsp;</p><p>Of particular concern is the cleaning of systems containing strong oxidizers such as liquid oxygen (LOX) or hypergolic fuels.&nbsp; Currently, precision cleaning at Kennedy Space Center is performed using dual-solvent process in which the first solvent, Vertrel MCA, is used to clean the component and a second solvent, HFE-7100, is used as a final rinse and analytical test fluid.&nbsp; Highly fluorinated compounds such as those used in Vertrel MCA are extremely persistent in the environment and are potent greenhouse gases. Continued use of this or similar solvents will lead to high remediation costs that must be carried by the Program for years to come.</p><p>Historically, precision cleaning has used chlorofluorocarbons (CFCs), such as Freon, because it was non-toxic and performed extremely wll.&nbsp; When Freon, and other CFCs, were banned due to their harmful environmental effects, new solvents were identified that were similar compounds but were not yet regulated.&nbsp; Eventually, these solvents also become regulated and unavailable for use.&nbsp; This project specifically did not consider halogenated solvents in order to find solvents or technologies that would not face future environmental regulations.</p>
