Piasecki Refreshes Hybrid Chinook Concept
AURORA, Colorado—Piasecki Aircraft says an updated version of long-running concept studies of a radically modified Boeing CH-47 Chinook combining the helicopter’s existing twin-rotor system with a tiltwing and twin tilting ducted fans has become more relevant with the U.S. Army’s growing drive for longer range troop transport and logistics support.

In 2008 Piasecki and Boeing revealed they had worked together on a “minimum” modification of the Chinook, called the Tilt Duct CH-47, which included a simplified version of the Vectored Thrust Ducted Propeller flown on Piasecki’s X-49A Speedhawk. Other proposed changes to the basic CH-47 at the time included bigger engines to drive the rotors and props, relocating the fuel tanks under the cabin, streamlining the aft fuselage and fairing the hubs to reduce drag.
