Abstract

L'invention concerne un ensemble de propulsion (1) pour un aéronef à décollage et atterrissage verticaux, comportant une hélice (2) apte à être entraînée en rotation autour d'un axe (X) par un moteur (3), et un carénage (5, 9) entourant ladite hélice (2), caractérisé en ce que ledit ensemble (1) comporte au moins une partie mobile (9) apte à modifier la distance axiale (d) entre l'hélice (2) et l'extrémité aval du carénage (5, 9).The invention relates to a propulsion unit (1) for a vertical take-off and landing aircraft, comprising a propeller (2) capable of being rotated about an axis (X) by an engine (3), and a fairing (5, 9) surrounding said helix (2), characterized in that said assembly (1) comprises at least one movable part (9) capable of modifying the axial distance (d) between the helix (2) and the end downstream of the fairing (5, 9).
