Piasecki Aircraft
Piasecki Aircraft Corporation (PiAC) was founded by American vertical flight pioneer Frank Piasecki to develop compound helicopters and other advanced rotorcraft after he was ousted from the leadership of his first company, Piasecki Helicopter which was renamed Vertol Corporation and later acquired by Boeing.〔Trimble 1982, pp. 257–258.〕
==History==
The company's origins dated back to 1936 with the formation of the P-V Engineering Forum in 1940 and it was renamed the Piasecki Helicopter Corporation in 1946. After a falling out with other owners, Frank Piasecki and some of his design team left to form Piasecki Aircraft Corporation in 1955. Piasecki Helicopter Corporation eventually became Vertol Aircraft Corporation (bought by Boeing to form Boeing Vertol and now called Boeing IDS Rotorcraft Division).
In 2005, the company was selected as prime contractor for two United States Army FCS UAV systems. The FCS Class III UAV system contract was awarded to the company in late 2006 following a competitive downselect of four competing technologies. As part of that effort, the company flew the world's first autonomous autogyro. The company has been developing and flight-testing the X-49 experimental compound helicopter since the mid-2000s.
