A Coanda system for controlling directions of an aircraft. The system includes a fluid passage defined in part by a casing wall having an inner surface facing the fluid passage. The fluid passage is configured to pass fluid from a first end inlet to a second end outlet. A fluid control element including a Coanda surface is disposed at the second end outlet. The fluid control element is moveable within the second end outlet to direct the fluid exiting the fluid passage between an upper gap and a lower gap, around the Coanda surface. A contour element is disposed on the inner surface of the casing wall upstream of the fluid control element, and further assists in directing the fluid to the open gap.
