Abstract
A vertical tail of a helicopter has a leading edge and a trailing edge concave toward the leading edge. The helicopter includes a main rotor and a tail rotor for generating anti-torque to cancel torque generated by rotation of the main rotor. The trailing edge is concave within a range within which the vertical tail overlaps a circular region, formed as a rotation range of the tail rotor, in a rotation axis direction of the tail rotor.
