Then he served as Chief Scientist for the U.S. Air Force (1950–1954) during which time he did important work on the structure of turbulence. Theodorsen then became the Chief of Research for the Republic Aviation Corporation (manufacturer of the famous P-47 Thunderbolt fighter plane of World War II, and after the war the F-84 Thunderjet and the F-105 Thunderchief) a post from which he retired in 1962 when he became an active consultant to the Sikorsky Helicopter Corporation where he specialized in ducted propeller work and helicopter rotors.

Famous quotes containing the word years:
“As death, when we come to consider it closely, is the true goal of our existence, I have formed during the last few years such close relations with this best and truest friend of mankind, that his image is not only no longer terrifying to me, but is indeed very soothing and consoling! And I thank my God for graciously granting me the opportunity ... of learning that death is the key which unlocks the door to our true happiness.”
—Wolfgang Amadeus Mozart (1756–1791)
“... it is use, and use alone, which leads one of us, tolerably trained to recognize any criterion of grace or any sense of the fitness of things, to tolerate ... the styles of dress to which we are more or less conforming every day of our lives. Fifty years hence they will seem to us as uncultivated as the nose-rings of the Hottentot seem today.”
—Elizabeth Stuart Phelps (1844–1911)
