2017 AIAA Regional Student Conferences

Credit: AIAA

The AIAA Regional Student Conferences, technical paper competitions held in each AIAA Region, give undergraduate and graduate students an opportunity to present their research on aerospace topics in a formal technical meeting atmosphere. Students are judged for technical content and clarity of communication by professional members from industry. The conference also provides a venue for students to share AIAA experiences, participate in social activities, connect with professionals, and exchange ideas about current topics in aerospace engineering. Support for the student conferences is provided by the AIAA Foundation and the Region’s professional members.

The AIAA Foundation awards prizes to the top three winners in the Masters, Undergraduate, and Team categories. The first-place winners of the Regional Student Conferences are invited to participate in the AIAA Foundation’s International Student Conference, held each January in conjunction with the AIAA SciTech Forum. This event gives students an opportunity to meet winners from other AIAA Regions, network with professionals from industry, and present their work to a new set of judges. The students’ papers are also published as part of the AIAA SciTech.

(Region VII—Australia Student Conference will take place 23–24 November at Royal Melbourne Institute of Technology (RMIT) in Melbourne.)

AIAA Distinguished Lecturer Bevilaqua Speaks at Western Michigan University

Credit: AIAA

The AIAA Western Michigan University Student Branch welcomed back Dr. Paul Bevilaqua for a second time to share his talk: Inventing the Joint Strike Fighter. Rather than sharing details on the F-35s performance and capabilities, the presentation largely focused on the design process from the early mission requirements from DARPA and the U.S. military up to final detail design and testing. This format was especially interesting for engineering students and faculty alike as this lecture provided real-world applications of the concepts and fundamentals covered in aerospace engineering curriculum. Several concepts ranging from lasers to individual turbines driving the lift fan were discussed. Eventually Dr. Bevilaqua’s proposal of a shaft driven from the main engine to the lift fan was adopted by Lockheed Martin. Thermodynamic cycle analysis of the new propulsion system was also presented, which further reinforced concepts covered in undergraduate engineering courses.

AIAA Student Branch Chair Tyler Wall highly recommends the AIAA distinguished lecture program to other student chapters. Each year, the distinguished lecture manual available is updated and provides a list of speakers and processes to conduct one of these events. Student branches interested in taking advantage of this program should start the planning process early in the fall.

AIAA Delaware Section Participates in Mission: Space

Credit: AIAA

The K–12 STEM Outreach Committee would like to recognize outstanding STEM events in each section. Each month we will highlight an outstanding K–12 STEM activity; if your section would like to be featured, please contact Supriya Banerjee (1Supriya.Banerjee@gmail.com) and Angela Diggs (Angela.Spence@gmail.com).

When the AIAA Delaware Section heard about a program called Mission: Space occurring in its own backyard, the section knew it had to get involved. Bunker Hill Elementary School in Middletown, DE, started the program as an opportunity for its 4th and 5th grade students to use telescopes to examine the stars as part of their science unit on the night sky. The program grew to include all 4th and 5th grade students in the Appoquinimink School District. The students are not only using telescopes, but there are keynote speakers, hand-on activities and other exhibits for the students to explore, all designed to increase excitement and enthusiasm for space sciences.

This year was the first year the AIAA Delaware Section participated. Section Chair Breanne Sutton learned about the event at a STEM Mixer for the state of Delaware, and the section volunteered to host one of the hands-on activities, and Ms. Sutton was asked to be one of the keynote speakers. The planners were very excited to have a female keynote speaker for the STEM event.

On 24 January, over 500 students and parents attended the event at Appoquinimink High School. ILC Dover was in attendance with their display spacesuit, moon rocks were on loan from NASA, astronaut food was for sale, and the students could enter an inflatable planetarium set up in the gym. The AIAA Delaware Section hosted a planetary lander activity, which had detailed instructions, a supply list, and even an instructor worksheet available online (https://www.nasa.gov/pdf/418011main_OTM_Touchdown.pdf). The activity was so popular that the volunteers had to make a mid-activity run to the store for more supplies and set up more tables. The seven volunteers who staffed the activity were busy all night, with students still working to improve and test their landers as the program ended. The section plans to host an activity booth at future Mission: Space events, alternating between two activities so there is a new experience for students each year they attend.

He was the head of the Department of Mechanical, Industrial, and Aerospace Engineering at Rutgers University for 15 years before becoming the Dean of Engineering at Texas A&M University and then held the James M. Forsyth Professor of Mechanical Engineering Endowed Chair until his retirement.

He gained international recognition for his research in flow separation analysis and its application to practical problems. He presented over 170 lectures and over 250 professional papers. Dr. Page was noted for his research and teaching on non-isoenergetic supersonic base flow, thermodynamic second law solution of subsonic base flow, and impingement jet flows. He thought his principal accomplishments were the development of strong, successful engineering education programs.

In 1984, he was honored as the first non-German scientist to be appointed an Honorary Professor at Ruhr University in Bochum, Germany. He was a fellow of the American Society of Mechanical Engineers, the American Society of Engineering Education (ASEE), AIAA, the Accreditation Board of Engineering and Technology, the American Astronautical Society, and the American Association for Advancement of Science. He was awarded the AIAA 50-year pin commemorating his contributions to the advancement of the arts, science, and technology of aeronautics and astronautics at Texas A&M and the Johnson Space Center.

Obituary

AIAA Fellow Tischler Died in January

Adelbert O. “Del” Tischler passed away 12 January.

Mr. Tischler joined the National Advisory Committee for Aeronautics in 1942 at the Aircraft Engine Research Laboratory (AERL). Drafted into the U.S. Air Force, he was transferred back to the AERL laboratory (now NASA Glenn Research Center) to develop fuels of 150-octane rating for wartime aircraft piston engines.

In 1950, Tischler began work to eliminate “screaming” in liquid rocket combustion chambers. These investigations led to methods of limiting the problem in later engines. He also worked with others on design, building and operating rocket combustion chambers using liquid hydrogen as the rocket fuel, with oxygen and fluorine used as oxidizers. He was the safety officer at the research test site for these experimental operations.

In 1958 Tischler began work with other scientists and engineers to lay out a plan for U.S. space exploration. These working groups set forth most of the missions, equipment requirements and basic plans for NASA. Tischler was appointed Director of (Rocket) Propulsion Developments in NASA’s Office of Manned Space Flight (OMSF). He was charged with initiating and developing the F-1, RL-10 and J-2 engines used on the Saturn series of vehicles. In 1960 solid propellant rocket technology was also assigned to his supervision.

He went on to serve as the Director of the Chemical Propulsion Division in the Office of Advanced Research and Technology (1964–1969). Tischler then served as the Director of the Shuttle Technology Office (1970–1972) and worked on several task forces aimed at finding more cost-effective methods for space operations prior to his retirement in 1973.

During the late 1970s and early 1980s Tischler was a consultant to the European Space Agency in the construction of the first reusable SpaceLab system and the follow-on job of generating the first SpaceLab payload. With Dr. Dah Yu Cheng, Tischler formed a company to develop gas turbine systems operating on a new cycle capable of achieving energy conversion efficiencies of fifty-eight. About 100 Cheng-cycle engines are presently in operation, generating electrical power around the world.

During the 1950s, Tischler served a term as president of the Cleveland-Akron Chapter of the American Rocket Society. He received the AIAA Wyld Propulsion Award in 1967. For his work on the Shuttle Technologies program he received NASA’s Exceptional Service Award. He published over 60 reports and journal articles as well as many notes on several topics related to aerospace endeavors.
