摘要
The present invention relates to a method for optimizing sections of a tail boom (10) for a rotary wing aircraft, and also to a tail boom (10) including such sections. The method comprises the step of: creating a database characterizing standard sections for a tail boom (10) which give precedence to minimizing a negative lift (FD) and/or to increasing a lateral force (FL) generated by air stream from a main rotor of an aircraft flowing over the tail boom (10); a step of establishing searched aerodynamic and structural characteristics for the tail boom (10); and a step of defining the sections of the tail boom (10) as a function of the standard sections and of the searched aerodynamic and structural characteristics. The tail boom (10) as defined in this way optimizes a reduction in the negative lift (FD) and/or increase in the lateral force (FL) generated by the air stream from the main rotor.
