Supersonic flight expert dies

Wallace Hayes, professor of mechanical and aerospace engineering, emeritus, who made numerous fundamental contributions to the understanding of supersonic flight and supersonic aircraft design, died March 2 in Hightstown, N.J., after a long struggle with Parkinson's disease. He was 82.

A memorial service is planned for 1:30 p.m. Sunday, April 22, at the University Chapel.

In a series of publications beginning in 1947 with his Ph.D. thesis at the California Institute of Technology, Hayes developed a theory of supersonic flow called the "supersonic area rule" which strongly influenced the design of high-speed aircraft. His work also provided the first understanding of the behavior of delta wing aircraft flying just above the speed of sound.

He followed his work in supersonic flow with groundbreaking studies in the late 1940s and early 1950s in hypersonic flow, which is considered to begin at about five times the speed of sound, or Mach 5. He developed the "Hayes similitude principle," which enabled designers to take the results of one series of tests or calculations and apply them to the design of an entire family of similar configurations where neither tests nor detailed calculations are available. Many of his developments appeared in his classic book "Hypersonic Flow Theory," co-written with Ronald Probstein and first published in 1959.

Always cognizant of the critical problems of supersonic flight, he made important contributions to the understanding of sonic booms and served on numerous National Aeronautics and Space Administration advisory committees on the subject.

Hayes earned his B.S. in physics in 1941 and his Ph.D. in physics, magna cum laude, in 1947 from the California Institute of Technology. After working in the aircraft industry and in the U.S. Office of Naval Research in London, he came to Princeton University in 1954 and taught until 1989. He also taught at the California Institute of Technology, Brown University, Delft Technical University, the Ecole Polytechnique and the University of New Mexico at Holloman Air Force Base.

He was honored for his work by election to the National Academy of Engineering, the American Academy of Arts and Sciences, the American Physical Society and the American Institute of Aeronautics and Astronautics, which honored him in 1965 with its Research Award.

Hayes was an active member of the Sierra Club since 1942 and an avid outdoor sports enthusiast enjoying rock-climbing, hiking, water sports and skiing. He was also a glider pilot and small airplane flight instructor.

Survivors include his former wife, Laura; and three daughters, Carolyn, Judith and Barbara Hayes. In lieu of flowers, the family asks that donations be sent to the Sierra Club Memorial Program, 85 Second St., Second Floor, San Francisco, CA 94105-3441.
 


Donavan was versatile coach

Edward Donovan, 91, a longtime coach at the University, died March 15 at his home in Princeton.

Over a period of 55 years, Donovan coached baseball, football and basketball and taught squash, tennis and golf. He continued to work with student athletes until he was 88.

"Ed Donovan was a terrific leader," said Gary Walters, director of athletics. "He was a man of few words, but of great character. By his actions, he spoke volumes."

Walters said Donovan inspired others with his versatility. "Most of us, as we get older, suffer from psychosclerosis -- I'm inventing words -- a hardening of the attitudes," said Walters. "Eddie continued to grow as a person in his retirement in ways that continue to influence Princetonians far and wide. He was the antithesis of the specialist -- he was multi-dimensional. He was in contact with the great figures in Princeton's sports history."

Donovan came to Princeton in 1943 to take charge of athletics in the Navy V12 program, assisting the coaches of the football, baseball and basketball teams. He was the head baseball coach from 1952 to 1975. He also coached the junior varsity football and freshman basketball teams and scouted for the varsity basketball team during his tenure. In addition, he taught squash, tennis and golf in physical education department from 1946 to 1998. In collaboration with his wife, he wrote a book about his experiences at the University titled "My 55 Years at Princeton," which was published last year.

Donovan was a member of Springdale Golf Club, the Nassau Club and St. Paul's Roman Catholic Church.

Survivors include his wife, Betty Whelan Donovan. A memorial service is scheduled for 10:30 a.m. Saturday, April 14, at the University Chapel; it will be followed by a reception. There will be a tribute to Donovan at the Columbia-Princeton baseball game at 1 p.m. that day.

Memorial contributions may be made to the Edward Donovan Baseball Fund in the Department of Athletics or to the Hospice Program at the Medical Center at Princeton.
