   The NASA Glenn Research Center is bringing the excitement of aeronautics and space exploration to Hidden Hollow 2012 with a traveling exhibit! NASA Glenn is responsible for NASA outreach programs and events in Ohio, Indiana, Illinois, Michigan, Minnesota and Wisconsin. NASA exhibits provide unique insights into the past, present and future of air and space travel. For some events, members of their Speakers Bureau and other NASA employees may be present to staff the exhibit and interact with guests. However, at this time we're not sure of what exhibit we will get or if they will provide a representative. Please check back in the future! What we do know at the moment is that NASA Glenn's Community and Media Relations Office and Visitor Center provide a variety of traveling exhibits, including the following:
We are sorry to announce that due to the huge size of the NASA Tour Bus (a semi-trailer) and the huge expense of getting it here and insuring it, we are not going to be able to have the large exhibit. However! Do not count NASA out. We have requested a smaller exhibit and also have a request in for a NASA Glenn guest speaker. We are confident that they won't let us down. Stay tuned and we'll update you as soon as we find out more. And NASA certainly did not disappoint us. We'd like to welcome Dr. David Ellis as a guest speaker!  Dr. Ellis has worked since 1989 developing various high conductivity materials, primarily copper-based alloys and composites. He has contributed to the National Aerospace Plane, SP-100 space power, Generic Hypersonics and Reusable Launch Vehicle Second and Third Generation programs. He was the primary developer of GRCop-84 (?G R Cop eighty-four?), the first new alloy to be developed for rocket engine main combustion chambers in 40 years, and its successor, GRCop-84Z. He has also contributed to development of graphite and multiwall carbon nanotube reinforced copper matrix metal composites for engine applications and space-based radiator systems.
Under the Reusable Launch Vehicle Second Generation Program Dr Ellis led a team comprised of NASA, commercial vendors and end users and academia responsible for scaling up the production of GRCop-84 to a commercially usable scale. The effort was successful, and the rocket engine companies view GRCop-84 as a desirable material for future reusable rocket engines. Dr. Ellis has also worked on superalloys for jet engine disks under the Enabling Propulsion Materials program, a co-operative effort between NASA, Pratt & Whitney and General Electric. He was part of a team that developed the first new disk material to enter use in commercial and military aircraft engines in over 10 years. Currently Dr. Ellis is working on heat rejection systems for the fission power systems. He is working on the heat rejection team for the Technology Demonstration Unit, a concept test bed using full-scale components for a 40 kW electric power generation system. This unit will undergo extensive testing at NASA GRC beginning in 2013. Dr. Ellis is author or co-author of over 45 technical papers and will be giving us a program on the International Space Station! Please make him feel welcome... |
