ARTHUR P. ADAMSON

1919–2014

Elected in 1980

“Creativity, inventiveness, and engineering in the design and development of aircraft gas turbine and other engineering apparatus.”

BY M.J. BENZAKEIN

ARTHUR PAUL ADAMSON died at age 95 on May 3, 2014, in Philadelphia. He leaves behind a unique legacy at General Electric and in the world of aviation.

Art was born March 14, 1919, and raised in rural Kansas, where he was educated in a one-room schoolhouse. Engines and machinery were part of his life since his boyhood on a farm in Coffeyville, Kansas. He said he never had a doubt that he would become a mechanical engineer. “Farm boys always know a lot about machinery,” he said. “I like airplanes in particular. The engines are more fun than anything else.”

It wasn’t long before he succumbed to the call. After high school, he spent two years at a junior college in Coffeyville before packing his bags in 1939 and heading for Los Angeles. He moved in with his aunt and enrolled in the University of Southern California’s mechanical engineering program, supporting himself with summer jobs in an aircraft plant and a part-time job in the engineering school’s mechanical engineering lab. Sydney Duncan became his favorite professor; Thomas (“Pop”) Taylor Eyre, then chair of the Mechanical Engineering Department, was his inspiration. He graduated at the top of his class in 1941.

He joined GE a month after graduation and spent his early years working on rocket and jet engine programs in

Philadelphia and then Schenectady. He also enrolled in GE’s advanced technical training program, which allowed him to move into technical leadership positions. This was the beginning of his four-decade career at General Electric, where he left a remarkable, long-lasting legacy.

In the late 1950s he became a technical leader on GE’s lift fan program and manager of the J85 engine program. He took a young Brian Rowe under his wing, and Rowe recalled him as “probably the most intelligent person working” at GE Aviation.

When the US Army awarded the GE12 demonstrator program in 1967, Art led the team on the radically efficient design. This led to a production contract in 1972, and the GE12 became the first version of the T700 helicopter program—still going strong with more than 15,000 engines in service. He also helped develop the TF34 family of turbofan engines used in the Navy’s antisubmarine aircraft, the Warthog, and in regional commercial passenger jets.

In 1955 he moved to Evendale, Ohio, a suburb of Cincinnati, to oversee rocket engine development. In 1959, while the country scrambled to catch up with Sputnik-era launch capabilities, he became chief engineer of the Vanguard rocket engine program. A successful launch powered the first satellite into an Earth-orbiting trajectory on 24,000 pounds of thrust.

“His creative genius led to several aircraft engine programs,” said USC classmate and fellow GE engineer Robert Hoffman, a resident of Redwood City, California. “One of them was the XV-5A lift fan for vertical launch, high-speed helicopters. That was a very rewarding program and a great vehicle to see take off.”

In 1967 GE Aviation was determined to reenter the large commercial engine market in a big way. The company turned to Art to lead the initial CF6 engine development effort, based heavily on the TF39 military engine. Rowe soon led the CF6 project and worked closely with his engineering mentor, leading to the successful launch of the initial CF6-6 on the DC-10.

But the CF6 really came into its own with the higher-thrust CF6-50. And again Art Adamson played a central role: he

created the design concept that enabled the CF6-50 to grow in thrust while keeping the turbine temperatures manageable. As Rowe later said, the CF6-50 would not have been possible without Art and his design team.

In the 1980s Art led the design team that created GE’s ultra-high-bypass unducted fan (UDF) engine and became the “father of the UDF.” The engine was a revolutionary concept that addressed the needs for low fuel consumption in the industry. Art’s team designed this new propulsion system in cooperation with SNECMA of France. The team demonstrated its performance in flight tests on the Boeing 727-100 and MD 80 aircraft. When fuel prices dropped, interest in the fuel-efficient UDF engine waned and the unique engine never entered airline service. The concept, however, is being revived today in advanced studies at NASA and in the Clean Sky program in Europe.

Art’s technology innovations on the program were extraordinary. For example, without the composite fan blades developed on the UDF, it is unlikely that the GE90 ultra-high-bypass ratio engine for the Boeing 777 airplane would have seen the light of day. He and his team were awarded the Collier Trophy for their achievements.

Art retired from GE in the late 1980s but continued for many years as a consultant. In 1989 he was inducted into GE Aviation’s Propulsion Hall of Fame.

Few engineers have influenced the jet propulsion industry as Art Adamson. And he enjoyed more than most sharing his creativity and wisdom with those around him. His years as a consultant at GE were invaluable. He participated in “technical circuses,” which are technical reviews of newly developed products; his comments were few and to the point. When Art spoke, we all listened.

Through the years, he received some of the most prestigious aviation industry awards around: GE’s Charles P. Steinmetz Award for “concepts in developing electric motors, guided missile autopilots, electronic controls, rocket propulsion systems, and the CF6, T700, and CF34 jet engines”; GE’s Perry T. Egbert Jr. Memorial Award “for outstanding creativity in

the development of the CF6-50 Commercial Jet Engine”; and SAE’s Franklin W. Kolk Air Transportation Progress Award for service to aviation (1985). He was elected to the National Academy of Engineering in 1980, a recognition that he highly deserved.

Art had multiple interests when he was not working; he was a devoted husband and father as well as an avid downhill skier, tennis player, world traveler, wood carver, and prolific reader. He was married for 59 years to the late Florence (Smith) Adamson, of Schenectady, and is survived by son David Adamson, daughter Judith Adamson, five grandchildren, two great-grandchildren, brother Charles Adamson, and five nephews and five nieces.

He will be greatly missed.

This is the 19th Volume in the series Memorial Tributes compiled by the National Academy of Engineering as a personal remembrance of the lives and outstanding achievements of its members and foreign associates. These volumes are intended to stand as an enduring record of the many contributions of engineers and engineering to the benefit of humankind. In most cases, the authors of the tributes are contemporaries or colleagues who had personal knowledge of the interests and the engineering accomplishments of the deceased. Through its members and foreign associates, the Academy carries out the responsibilities for which it was established in 1964.

Under the charter of the National Academy of Sciences, the National Academy of Engineering was formed as a parallel organization of outstanding engineers. Members are elected on the basis of significant contributions to engineering theory and practice and to the literature of engineering or on the basis of demonstrated unusual accomplishments in the pioneering of new and developing fields of technology. The National Academies share a responsibility to advise the federal government on matters of science and technology. The expertise and credibility that the National Academy of Engineering brings to that task stem directly from the abilities, interests, and achievements of our members and foreign associates, our colleagues and friends, whose special gifts we remember in this book.
