A plurality of cascade vanes (28, 29, 30) for directing a flow of gas (20) is provided with at least one flow regulating vane (36) which counterrotates with respect to the cascade vanes (28, 29, 30) over a gas flow vectoring range of motion. The cascade vanes (28, 29, 30) and flow regulating vane (36) corotate when moving through an adjacent stowing range of motion for achieving a stowed, gas flow blocking arangement.
