CONTRIBUTIONS TO SCIENCE, ENGINEERING & EDUCATION
By Shao Wen Yuan

　　During his lonq engineerinq career. 　he has unceasingly achieved　innovative concepts for multiple 　areas of engineering and applied　science, both fundamentals and applications , such as :

　　●　Invention and pioneer work on Jet Circulation Control VTOL Rotor .systems. Obtained patents with co-inventor , Dr. Theodore von Karman- this innovative concept has had very significant impact on the current development of high lift device system for STOL aircraft, and has led to the development of the X-Wing program, NASA-DARPA hundred-million-dollar project .

　　●　Founder of the Consortium of Universities for Promoting Graduate AerosPace Studies (CUPGAS) . Most Aerospace Engineering Graduate School　have been experiencing sharp declines in the enrollment of full-time　American students daring the past decade. The situation is causing great concern to the industrial and governmental aerospace eommunity　if the United States is to maintain its preeminent position and　strengthen its national defence capability. The proposed solution 　consists of a combined 5-year program which has been designed to　enable beginning senior physics and mathematics students in liberal　arts colleges to complete a Bachelor's degree and Master's degree　in Aerospace Engineering in two years. Currently. there are over one hundred universities and colleges which are interested in participating　in this timely and vital program, and many liberal arts colleges are　preparing to recruit 1987 freshman students for the CUPGAS program.

　　●　Development of the Glenn L. Martin-Yuan Low Drag Airfoil which was successfully used in both Martin 202 and 404 commercial airplanes and　experimental military planes. It was known to be the most efficient　airfoil in mid-nineteen-forties . In conseqllence of his outstanding achievements, Mr. Glenn L. Martin requested in person to Dr. Theodore　von Karman in 1944 to recommend to Martin Company 10 Ph.D. from Caltech　like Dr Yuan's caliber.

　　●　Pioneered the research work on Mass Transfer Cooling under Project 　SQUID - this work was first to be published in the field. and has had　very significant impact on the development of reentry nose cone cooling　combustion chamber cooling and early heat pipe research.

　　●　 Creative application of mathematics to the solution of thin shell　problems (with Dr. Theodore von Karman) - this research has had very　signiiicant influence on later structural design of nuclear reactor　and offshore drilling platform supportors . After 45 years. this work
is still used by researchers for references and applications.

　　●　 Invention and research work on Wing-tip Vortex Abatement - the NASA　V/STOL tunnel testing resuLts indicate a reduction of wing-tip vortex　strength more than 40% with Yuan's devices on a typicai wing in comparison with those without the devices. The concept also has applications to the abatement of helicopter rotor slap noise. In　consequence of this invention. Mr. James McDonnell of McDonnell-Douglas　Corporation made a special trip to Washington. D.C. on January 27,1975　see Dr. Yuan with regard to using this invention on DC-10 airplanes. Unfortunately, the April 1975 crash of DC-10 in Paris has led to the　sermi-retirement of Mr. James S.McDonnell.

　　Dr. Yuan's pioneering research work and creative achievements in the fields of aerosoace engineerinq and energy have had significant impact upon the advancment of modern technical knowledge . He has published three books and over eighty scientific and technical articles in some twenty-five U.S. and international journals , and has received over twenty U.S. and foreign patents. His book, entitled "Foundations of Fluid Mechanics , has been adopted by universities throughtout the world. He has been invited as a guest lecturer by universities and research institutes in fifteen countries.

　　He is a member in eight honorary societies, a Fellow of American　Association for the Advancement of Sciences and of the American　Institute of Aeronautics and Astronautics. He has been the President　oE the Society of Engineering Science, and was the Founder and　Chairman of the highly successful First U.S.-China Conference on　Energyt Resources, and Environment. He is listed in various　national and international biographies including Who's Who in the World International scholar Directory and Who's Who in America,　and was selected by the Chinese American Society in 1983 as one of　the Forty Outstanding Chinese American in U.S.A. who have won　acclaim and made valuable contributions in their fields. During　his 50th annual class-reunion at both Michigan and Caltech, he wasrecognized by his classmates as one or the most accomplished alumni.

　　Dr. Yuan was a partner of the technical consulting company, von　Karman,Yuan and Arnold, and the Founder of RISE (Residential and　Industrial Solar Energy) , Inc. After his retirement as a Professor　Emeritus of the George Washington University in 1984 , he was　concerned with the sharp declines in the enrollment of American　students in most Aerospace engineering graduate school . Without　any kind of help, he singly established, after two years devoted effortst the Consortium of Universities for Promoting Graduate　Aerospace Studies (CUPGAS) in orer to remedy this Nationl's critical　situation. The Founders Meeting, attended by some twenty mernbers,of CUPGAS was held on December 5, 1986 in Hampton, Virginia.

　　Dr. Yuan married Hui Chih Hu of Hong Kong in 1950. He became an　American citizen in 1954.
　　Currently,establishment of Yuan Fellowship Fund to support　engineering graduate students pursuing a Ph.D. degree is under　discussion with one of his alma maters.
　　The hightlights of his contributions to science, engineering and　education are depicted in the following two pages.
