Piasecki Aircraft has moved its SpeedHawk compound-helicopter demonstrator to Boeing's flight-test facility in Wilmington, Del. in preparation for ground runs in April. The modified Sikorsky Aircraft UH-60 includes Piasecki-designed fixed wings and a vectored-thrust ducted propeller mounted on the end of the tail boom. Essington, Pa.-based Piasecki aims to achieve speeds in excess of 200 kt with the design. The company in the past developed the design with U.S. Navy funding. The latest work is being done under U.S. Army Fiscal 2007 funding.
