Early life and education


Born in Philadelphia, Pennsylvania to an immigrant Polish tailor, Piasecki worked for autogyro manufacturers while still attending Overbrook High School,[3] then studied mechanical engineering at the University of Pennsylvania before graduating with a bachelor's degree from New York University. He was employed by the Platt-LePage Aircraft Company as a control engineer on their XR-1 twin-rotor project.[4] In 1940, he formed PV Engineering Forum with former Pennsylvania classmate Harold Venzie.[5] He built a single-person, single-rotor helicopter designated the PV-2 and flew it on April 11, 1943. This helicopter impressed the United States Navy sufficiently to win Piasecki a development contract.[6]


Career

The name PV Engineering was changed to Piasecki Helicopter Corporation in 1946. After a boardroom dispute, Piasecki was forced out of Piasecki Helicopter in 1955, and formed the Piasecki Aircraft Company.[7]

At Piasecki Aircraft, he participated in the development of the Piasecki 16H-1 the world's first shaft driven compound helicopter, the PA-59K/VZ-8P Flying Geep (also known as the AirGeep) the Piasecki PA-97 Helistat heavy vertical airlifter and the Piasecki X-49 experimental compound helicopter.


Personal life


Piasecki married Vivian Weyerhaeuser on December 20, 1958.[8] They had seven children: Nicole, Frederick, John, Lynn, Frank, Michael, and Gregory.[7]

His son John W. Piasecki is now President and CEO of Piasecki Aircraft. His son Fred W. Piasecki is Chairman of the Board and Chief Technology Officer of Piasecki Aircraft.[9] His daughter Nicole Piasecki is vice president and general manager of Propulsion Systems for Boeing Commercial Airplanes.[10]


Later life and death


Piasecki died at his home on February 11, 2008 of a heart attack after a series of strokes. He was 88.
