    摘要： A tail rotor arrangement for rotary wing aircraft, comprising a tunnel of axis X--X transverse with respect to the aircraft and in which is disposed a multi-blade rotor coaxial with respect to the tunnel and generating a transverse air flow. The arrangement comprises a plurality of fixed blades disposed inside of the tunnel downstream of the rotor with respect to the air flow and arranged in at least substantially radial manner with respect to the tunnel in order to be able to recover, in the form of an axial thrust, the energy of rotation of the air flow at the outlet of the rotor. The tail rotor arrangement provides an increase in thrust of the rotors, particularly paired rotors.
