Tail Rotor Design Guide

Abstract

The report presents general guidelines for the preliminary design of tail rotors for single-rotor helicopters in low-speed and hover flight. Application of these guidelines should alleviate the directional control problems of single-rotor helicopters under certain conditions of wind speed and direction, height above the ground, gross weight, and altitude. The main data base used to develop the guidelines is the results of a wind tunnel test of a tail rotor helicopter model conducted by Boeing. These tests were conducted in and out of ground effect, in various wind speeds to 35 knots, and with varying wind azimuths.
