By incorporating an articulating and telescoping duct into the flow path of the reaction drive it is possible to route the exhaust gases from the engine to the rotor blades with less total duct length and with fewer bends than was heretofore possible, thereby reducing the total losses associated with the ducting with a concomitant increase in aircraft efficiency.
