He meant quantum as in signifi cant, not as in the decisions may play applied physics experiment due to unfold shortly in the International Space Station’s Cold Atom a part in future research onboard Laboratory [See “Quantum Promises,” Page 16]. the International Reagan’s speech illustrates how hard it is to predict the return on investments from space research, Space Station. Por to foresee the research that creative human beings will conceive. Our markets here on Earth aren’t yet teeming with products that “could be only manufactured in space,” as Reagan predicted. Who could have guessed in 1984 that the station would be a venue for quantum physics research that could point to a whole new way of performing deep space navigation? The future of ISS after 2024 will probably be just as hard to predict, even if NASA and its international partners succeed at transitioning this $80 billion conglomeration of modules and living space to the control of a private entity of some kind. One open question is just how much autonomy that private entity would be granted to apply market prin- ciples to the future of ISS. Congress and NASA have constrained the conversation in at least one important way. The “NASA Transition Authorization Act of 2017” envisions NASA becoming “one of many customers of a low-Earth orbit non-govern- mental human space fl ight enterprise.” That sounds like a call for an independent enterprise, except that the station would remain a “human space fl ight enterprise.” A similar constraint is refl ected in NASA’s congressionally mandated “International Space Station Transition Report,” released in March. NASA lays down eight “core princi- ples” for the transition, four of which call directly or by inference for expanding or continuing human space fl ight. This language sounds a lot like offering to privatize a factory so long as the new owner agrees to keep all the workers. We need to remember that we’re living in an age of robotics and artifi cial intelligence. Today’s roles for astronauts on ISS might not apply to tomorrow, depending on how one answers the following philosophical question: Should the astronauts on ISS after 2024 be seen as space explorers or space workers? If they are workers, then business judgment must kick in or the business will be short-lived. A business leader would not care that “astronauts have continuously lived aboard the ISS for over 17 years,” as the NASA transition report gushes. He or she would need to see the business case for continued human occupation and by how many astronauts. Successful businesses do not keep workers on production lines, in coal mines or on space stations for the sake of tradition. And then there’s the mix of research to consider. Will that be decided by how many dollars customers are Ben Iannotta, willing to pay? By the likelihood of a return on investment? Or must the mix cater to the government’s defi nition editor-in-chief, of what “ultimately benefi ts people on Earth,” to use the NASA report’s language? [email protected] These are big questions without easy answers. It’s possible that initiatives like the quantum research in the Cold Atom Lab could be squeezed out by those with deeper pockets and better odds of a return on investment. That’s a bad thing if one’s goal is to open up deep space with fi ndings from this lab. But it could be a good thing if, for example, Parkinson’s disease lies in your future and the entity with the deeper pockets fi nds a treatment because of its research on ISS. Hard choices like this could lie ahead if the market for space research turns as red hot as many hope. ★ 4 | OCTOBER 2018 | aerospaceamerica.aiaa.org CORRECTION 1 Three of the photos on the Looking Back pages in the September issue were placed next to the wrong dates.

  • ACE's Scandinavian Sojourn
    ACE’s Scandinavian Sojourn : A Southerner’s Perspective Story by: Richard Bostic, assisted by Ronny Cook When I went on the ACEspana trip back in 2009, it was by far one of the most amazing vacations I have ever experienced. In addition to getting to visit parks in a different culture than we see here, it is also a great opportunity to spend time with fellow enthusiasts and grow friendships while enjoying our common interests. When Scandinavia Sojourn was announced for the summer of 2011, I knew it was a trip I could not miss. Since the 2009 trip was my first trip to Europe I thought that there was no way the over- all experience could be better in Scandinavia. I was wrong. We landed in Helsinki, Finland around 1300 the day before we were required to be at the hotel to meet with the group. Helsinki is an interesting city and fairly new compared to many cities in Europe. Walking around the city you can see the Russian influence in the city’s architecture. In fact, many movies during the cold war would use Helsinki to shoot scenes that are supposed to be set in the Soviet Union. After making our way to the Crowne Plaza Hotel and getting a quick lunch at the hotel restaurant we decided to spend the remaining time that afternoon checking out some of the sites around our hotel. Some of these sites included the Temppeliaukio Church inside of a rock formation, the train station, Routatientori Square and National Theater, and a couple of the city’s art museums.

  • Limits to Principles of Electric Flight
    AIRCRAFT DESIGN AND SYSTEMS GROUP (AERO) Limits to Principles of Electric Flight Dieter Scholz Hamburg University of Applied Sciences https://doi.org/10.5281/zenodo.4072283 Deutscher Luft- und Raumfahrtkongress 2019 German Aerospace Congress 2019 Darmstadt, Germany, 30.09. - 02.10.2019 Abstract Purpose – This presentation takes a critical look at various electric air mobility concepts. With a clear focus on requirements and first principles applied to the technologies in question, it tries to bring inflated expectations down to earth. Economic, ecologic and social (noise) based well accepted evaluation principles are set against wishful thinking. Design/methodology/approach – Aeronautical teaching basics are complemented with own thoughts and explanations. In addition, the results of past research and student projects are applied to the topic. Find ings – Electric air mobility may become useful in some areas of aviation. Small short-range general aviation aircraft may benefit from battery-electric or hybrid-electric propulsion. Urban air mobility in large cities will give time advantages to super-rich people, but mass transportation in cities will require a public urban transport system. Battery- electric passenger aircraft are neither economic nor ecologic. How overall advantages can be obtained from turbo- electric distributed propulsion (without batteries) is not clear. Maybe turbo-hydraulic propulsion has some weight advantages over the electric approach. Research limitations/implications – Research findings are from basic considerations only. A detailed evaluation of system principles on a certain aircraft platform may lead to somewhat different results. Practical implications – The discussion about electric air mobility concepts may get more factual. Investors may find some of the information provided easy to understand and helpful for their decision making.

  • Robert Channing Seamans, Jr
    Daniel Guggenheim Medal MEDALIST FOR 1995 For lifelong technical contributions and technical leadership in academia, industry and government as NASA Deputy Administrator during the Apollo program and in several other government positions. ROBERT CHANNING SEAMANS, JR. Robert Seamans played a major role in the Apollo Program, which brought preeminence to the United States as a “manned space faring nation.” He graduated from Harvard with the class of 1940. He and a fellow classmate decided to look into the possibilities of an advanced degree in engineering from MIT. Seamans was admitted as graduate student Professor Draper’s multi-disciplinary program called “The Instrumentation Program” program. This was the beginning of a long and fruitful relationship between Draper and Seamans, who ultimately earned an SM and ScD in Instrumentation in 1951. His thesis involved the dynamic coupling between an airborne gunsight and airplane dynamics. Typically, for a Draper supervised thesis, Seamans verified his calculations with a flight test program, in which he innovated the use of a rapid change of the position of a control surface followed by a rapid restoration to the original position, which enabled him to determine the aircraft dynamics from flight data. This control motion has become standard and is called a “doublet.” During WWII Seamans was an instructor in the Department of Aeronautics and on the staff of the Draper Laboratory. He taught members of the Navy V-7 program and worked on or led several important classified fire control projects for the Navy and the Army Air Corps. In 1950 he became program manager of a joint MIT-lndustry project to develop an air to air missile, which was called the ‘Meteor.’ In 1954 he was hired by RCA and established the Airborne Systems Laboratory.

KERREBROCK Biographical Memoirs, VOLUME 78 PUBLISHED 2000 BY THE NATIONAL ACADEMY PRESS WASHINGTON, D.C. JEROME CLARKE HUNSAKER August 26, 1886–September 10, 1984 BY JACK L. KERREBROCK HEN JEROME C. HUNSAKER died in September 1984 at the Wage of ninety-eight, his illustrious career had spanned the entire existence of the aerospace industry, from the very beginnings of aeronautics to exploration of the solar system. His colleagues had extended from the Wright Brothers to Charles Stark Draper, and included virtually all of the founders and leaders of aeronautics and astronautics. Be- ginning with important technical contributions, he soon turned his attention to creating and managing the new in- stitutions needed to deal with the growth of the aeronau- tics industry. By the early 1930s he was at the pinnacle of the aeronautics industry with leadership roles in academia, government, and industry. In recognition of these achieve- ments, in 1933 he was awarded the prestigious Guggenheim Medal, the fifth such recipient after Orville Wright, Ludwig Prandtl, Fredrick Lanchester, and Juan de la Cuerva. His career continued at this level for nearly three decades. Even after his retirement in 1951 as head of the Depart- ment of Aeronautics at the Massachusetts Institute of Tech- nology, a department he founded in 1939, Hunsaker con- tinued as chairman of the National Advisory Committee for Aeronautics (NACA) until 1956, a position he had held 95 96 BIOGRAPHICAL MEMOIRS since 1941. Recognized the world over for his contributions to aeronautics, Hunsaker was also well regarded in the larger society.

  • H. Julian Allen
    Daniel Guggenheim Medal MEDALIST FOR 1969 For personal contributions to outstanding research and development leading to vastly improved re-entry bodies, missiles, satellites and spacecraft, and for leadership in directing and inspiring a large group of men at Ames Laboratory. H. JULIAN ALLEN A selfless, dedicated scientist whose personal reward was the safety of America’s astronauts—that was H. Julian Allen. It was Allen who, in 1952, conceived the concept of bluntness as an aerodynamic technique for solving the severe re-entry heating problem then delaying the development of ballistic missiles. His experiments revolutionized the fundamental design of ballistic missile re-entry shapes and were later applied to spacecraft. At the time he originated his research, Allen was a top engineer on the staff of the National Aeronautics and Space Administration’s Ames Research Center at Moffett Field, California. He had gone to Ames from the Langley Research Center, where his work with NASA had begun in 1936, and became chief of the High-Speed Research Division in 1945. Allen, a graduate of Stanford University, received in 1957 the Distinguished Service Award, the highest honor of NASA’s predecessor agency, the National Advisory Committee for Aeronautics, but his re-entry work was but one of his accomplishments. He developed a well- accepted theory for predicting forces at supersonic speeds on bodies at angles of attack, guided the experimental investigation of heat transfer and boundary layer development at supersonic speeds, and did important research into shock-wave boundary-layer interaction—all areas leading to vital progress in supersonic and hypersonic aerodynamics.
