How do you make a CH-47 Chinook cruise at 250-knots? Vectored thrusters!
Piasecki Aircraft, the Chinook’s legacy inventor, has filed a patent application for this unusual Chinook configuration.
Two ducted fans, with differential pitch propellers and horizontal vanes, are attached to each side of the CH-47 fuselage. Thrust generated by the fans can be vectored horizontally (to boost speed) or vertically (to increase lift).
