Jared Needle presented an interesting history of origami along with an impressive array of modern techniques, examples, and anecdotes. His mind-blowing array of artwork was very inspiring. But isn't this just an artform? Why would engineers be interested? Jared covered that, too! From flat-folding emergency structures to automobile impact-absorbing crumple zones to solar arrays and giant space telescopes, the relevance of this math-based artform is astounding.
Please check out Jared on Flickr
to see some of his fantastic artwork. Don't forget to join us at our next social!
This was a Social Event where we honored all of our award winners from the previous year. We attempt to intermingle our High School (Science Fair) winners with our mostly Young Professional (DCASS) winners, with our Professional (Longevity, Associate Fellows and Fellows, National Award, and Section Award) winners. We do this partly through a social in which our Science Fair winners put up their displays and talk to the rest of the attendees. Everyone is allowed time to meet the other award winners and enjoy themselves before the meal and award presentations. We have always cohosted this event with the Dayton ASME section with AIAA performing more of the planning and having more awards to distribute. This year we had nominally 105 attendees. The event was publicized via our newsletters and our website as well as by word of mouth at earlier events as well as by having flyers posted at various offices. All the award winners are also formally invited. It is also broadcast as part of the DCASS conference along with the Call for Section Awards.
There is no other event in Cincinnati like this… it’s all about getting students excited about science, technology, engineering and mathematics (STEM). Hands-on activities had kids of all ages experimenting, watching, touching, and creating. After a very busy day last year at this event, this year we combined Forces with the “Midwest Propulsion Group of Cincinnati to provide a full rocket experience to the students. Students were able to inspect small scale (2 meter) rockets and larger scale rocket components, and talk to engineers about how they work. Then they could build a “straw rocket” of their own and launch it at some targets. Our “ask the engineer” and “hands-on” activities were manned with volunteers from the section for the entire event. About 300 students designed, built, and launched a straw rocket and tried to hit targets with them. The event was promoted on our website and in our newsletters as well as through the many other organizations that participate at this event.
This was a new event for us this year. Space Day was a free, full family fun day for the community, with dozens of hands-on aerospace activities. The day also included a 5k fun run, a 1k kid’s fun run, and presentations from two astronauts. The AIAA section provided our straw rocket design/build/fly activity. In all, the kids (young and old) made and launched about over 200 straw rockets. The organizers thanked the AIAA team profusely for participating in Space Fest 2013, and commented that the straw rockets were very popular. The official door count for the event was 6,350. Museum officials estimate that this number is about 20% below the actual number of visitors, due to errors inherent in the system. More info at http://www.nationalmuseum.af.mil/spacefest.asp
An amazing tour was provided by Mr. Keith Wyman, showing off the extensive engineering and manufacturing capabilities of what many still call "Aeronca." More information about Magellan Aerospace can be found on the web at www.magellan.aero.
Aeronca Inc. is a major supplier of engine and nacelle components, aero-structures, and missile control surfaces for the military and for original equipment manufacturers in the United States and Europe, as well holding STC and PMA certificates for replacement cowl door structures for Boeing 737 -300, –400 and -500 aircraft. Aeronca also maintains FAA Certified Repair Station facilities for aftermarket support of its manufactured products.
Founded in 1928 as the Aeronautical Corporation of America at Lunken Field in Cincinnati, Aeronca was the first U.S. Company to produce and market a truly light airplane for the general aviation market. The Aeronca C-2 aircraft opened up flying to the public and helped make the company a major force in the general aviation market. The company moved operations to its current location in Middletown, Ohio in 1940 and changed its name to Aeronca in 1941.
Dr. Wadia is presently Chief Consulting Engineer – Aerodynamics at GE Aviation in Cincinnati, Ohio and our sections’ most recent AIAA Fellow. In his 29-year career at GE Aircraft Engines, he has been the manager for turbo-machinery aerodynamics, engineering systems program leader for large military engines and he discussed the history of fan aerodynamics technology evolution over the last twenty-five years. He focused on many of the GE engines that he has been involved with balanced by research on fans performed by other engine manufacturers. He outlined the history of fan development starting with shrouded fans on the CF6-80C2. Fan blade material technology developments were then discussed. With the rapid increase in fuel costs in the eighties, Dr. Wadia discussed aviation industry’s response with un-ducted fans (UDF), prop fans and counter rotating fans (CRISP). Wide chord fans (composite blades, hollow metal blades) followed by high flow swept blade technology demonstration and commercialization. He concluded with some multi-stage fan technology evolution and future trends in fan design.
This event was coincident with the 3rd annual student Flight Handling Competition and was co-sponsored by the Society of Experimental Test Pilots (SETP), the Society of Flight Test Engineers (SFTE), and the Royal Aeronautical Society (RAeS)
The U-2, SR-71 Blackbird, B-2 Spirit Bomber, and F-117 Stealth Fighter are some now high-profile examples of once hidden efforts of aircraft development in America. Are there more secret aircraft hiding in the shadows?
What goes on in "Area 51" and what specifically has happened or might now be happening in the secret or "black" world? What new technologies and missions are associated with these planes, where are they built and based, and how many are operational?
The presentation summarized many rumors and review publicly available evidence that suggests the existence of secret aircraft projects. The viability of the rumors and evidence were discussed and some additional ideas were offered.
On 16 March 2013, the Dayton/Cincinnati Section held its March Council meeting at the Midwest Propulsion Group (MPG) facility in Blue Ash Ohio. MPG is a turbine engine and rocket engine club. MPG’s membership is comprised of scientists and engineers from AFRL, GE Aviation and other local companies. It also includes students from University of Cincinnati and other propulsion enthusiasts. Many of its members are AIAA section members. Approximately 10 Dayton/Cincinnati members attended this meeting. Two students from Wright State University attended. MPG gave the section a tour of the facility. During the tour, MPG started and ran a turbine engine rebuilt by the group and test fire two rocket motors they had built. This was a STEM and YP event.
On March 16, 2013, two Section Council members, Oliver Leembruggen and Michael List, judged in the Special Awards category at the Science and Engineering Expo at the University of Cincinnati. This science fair serves as a regional competition for students in the Southwest Ohio area and typically has a large number of students proceeding to the state competition. Three winners were chosen from projects related to topics of interest to AIAA and its membership. These were selected based upon scientific process and method, ingenuity, quality of work, and overall understanding of the results.
For the fourth consecutive year, members went to Montgomery County Science Day held at the University of Dayton to search out the best aerospace related projects and recognize them with special awards. Two section members judged dozens of projects related to the aerospace field prepared by middle school and high school students. Three were selected based upon their work and were honored at our annual awards banquet in May. AIAA was listed in the program as a sponsor, and the AIAA awards were announced at the awards ceremony. The winners were invited to our awards banquet in May, where two of them also displayed their Science Fair work at a pre-banquet social especially for them. Here, they had chance to talk to aerospace professionals about their projects.
