Piasecki Aircraft has succeeded in conducting several ground runs of its X-49A SpeedHawk modification of the Sikorsky Aircraft H-60 Black Hawk. In doing so, it met its goal of starting the test cycle for the compound-helicopter demonstrator by the end of May; two ground runs were reportedly conducted in that month. Piasecki is looking to fly the aircraft this month under a program funded by the U.S. Army. The tests are being conducted at Boeing’s flight-test facility in Wilmington, Del. The modifications to the H-60 include 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.
