Abstract
A helicopter having a body and a tail boom connected, at the rear end, to an integral tail unit, and on which each of the vertical sections formed through the body and the tail boom presents a profile having a substantially ogival upper portion becoming gradually more pointed the closer the vertical section is to the tail unit, and a substantially flat lower portion blending, to form a substantially sharp edge, with the opposite ends of the upper portion; the connections between the upper and lower portions of the vertical sections defining two continuous edges extending from the front end of the body to the rear end of the tail boom, and intersecting a lower fin on the tail unit, the surface of which is a continuous arrow-shaped wing surface.
