A tail rotor device, which can be attached to a tail boom of a rotary wing aircraft, in particular of a helicopter, encompassing a sheathing, which forms an air flow channel with a channel depth running in the direction of a channel axis perpendicular to the vertical axis and longitudinal axis and an inner channel diameter, so that a tail rotor with rotor blades can be rotatably mounted in the air flow channel, wherein the sheathing is designed in such a way that its channel depth in a negative longitudinal direction tapers toward the back, wherein the objective is to improve the forward flight characteristics during operation and reduce the power consumption of the main rotor. This is achieved by virtue of the selected variable channel depth is always less than one fourth of the inner channel diameter, and the ratio between the variable channel depth of the sheathing in the direction of the longitudinal axis and the inner channel diameter of the sheathing lies between 20.5% and 14%.
