A rotorcraft is provided and includes a fuselage. The fuselage includes drag generating portions, a main rotor assembly and an auxiliary propulsor having an expected propulsion efficiency. The auxiliary propulsor is disposed to ingest boundary layer flows and in wake regions associated with the drag generating portions and is provided with a corresponding increase in the expected propulsion efficiency thereof.

    Giravion comprenant un fuselage. Le fuselage comprend des parties de production de traînée, un ensemble rotor principal et un propulseur auxiliaire ayant une efficacité de propulsion attendue. Le propulseur auxiliaire est disposé pour ingérer des écoulements de couche limite et dans des régions de sillage associées aux parties de production de traînée et est pourvu d'une augmentation correspondante de l'efficacité de propulsion attendue de celui-ci.
