186 Daniel C. Dugan Daniel Dugan graduated from West Point in 1955 and began his Army aviation career with primary flight training at Gary AAF, San Marcos, Texas. Following various military aviation assignments, he attended Virginia Polytechnic Institute at Blacksburg, Virginia, earning a master’s degree in aerospace engineering in 1963. After serving in Korea, he attended the U.S. Naval Test Pilot School at Patuxent River, Maryland, graduating in 1965. He was then assigned to the Army aviation test activity at Edwards AFB, California, as an experimental test pilot. There he was assigned as the project pilot on the YUH-1C gunship (XM-30), the ACH-47A armed and armored Chinook, and the YCH-47B. After a tour in Vietnam (1968-1969), he was assigned to the Army’s aviation laboratory at Ames Research Center, after completing a year at the Command and General Staff College. At Ames, Mr. Dugan flew the XV-5B lift fan, YOV-10A rotating cylinder flap research aircraft, and was the project pilot for the UH-1 V/STOLAND research helicopter and the XV-15 tilt rotor research aircraft. He remained the NASA project pilot on the XV-15 for 14 years and accumulated 200 hours in this unique aircraft. From 1990 through 1995, Mr. Dugan was assigned to Patuxent River as the NASA member of the V-22 test team. He is currently on the staff of the rotorcraft division at Ames Research Center and is assigned to a civil tilt rotor team for the development of tilt rotor displays, symbology, and operational procedures. Dan has authored over 20 technical reports and papers, many of which are tilt rotor related. He holds airline transport pilot certificates for both airplanes and helicopters and has accumulated over 7,000 hours of flight time.
