Engine pylon comprising a vortex generator, and method for the production thereof

摘要

The invention relates to a method for manufacturing an engine pylon (7) to be mounted between an engine (1) and an aircraft wing (6), said method comprising: mounting a pylon box (8) around a main structure (9), the box having a substantially oblong shape along which an air boundary layer (C) is formed while in flight; mounting at least one vortex generator (2) onto the pylon box such that a thickness (e) of the boundary layer is changed; and previously determining the shape of the pylon on the basis of the changed thickness of the boundary layer and the position of the vortex generators.

主权项

1. An engine pylon for an aircraft wherein the engine pylon comprises:
a pylon box around a main structure, the pylon box having an oblong shape along which an air boundary layer is formed during a flight of the aircraft; and at least one vortex generator mounted on the pylon box of the engine pylon, to modify thickness of the boundary layer, and in a longitudinal direction of the pylon box the at least one vortex generator is located between upstream and downstream ends of the main structure, and the main structure has a substantially parallelepiped shape with a width enlarged from 1 to 10% at its rectangular surface with respect to a corresponding width of a main structure of an engine pylon without a vortex generator for a same type aircraft as the aircraft, to improve transmission of absorption forces.
