A METHOD OF OPTIMIZING SECTIONS OF A TAIL BOOM FOR A ROTARY WING AIRCRAFT

摘要

The present invention relates to a method of optimizing sections of a tail boom (10) for a rotary wing aircraft and a tail boom (10) having such sections. Said method comprises a step of creating a database characterizing standard sections of a tail beam (10) that favors the reduction of a FD deportance and / or the increase of a lateral force FL generated by the flow. of a main rotor of said aircraft flowing over said tail boom (10), a step of establishing desired aerodynamic and structural characteristics of said tail boom (10) and a step of defining said sections of said tail boom (10); tail (10) according to said standard sections and said desired aerodynamic and structural features. The tail boom (10) thus defined optimizes the decrease of the offset F D and / or the increase of the lateral force F L generated by said air flow of said main rotor.
