US 11,028,801 B2 · Grating for the formation of a reverse flow of an aircraft turbofan engine

Abstract

A grating for the formation of a reverse flow of a turbofan engine and comprising fins of a first type having a curved profile whose rounding is oriented aft and whose center of curvature is forward relative to the fin of the first type, fins of a second type having a curved profile whose rounding is oriented aft and whose center of curvature is forward relative to the fin of the second type. In this grating, each fin of one of the two types is inserted between two fins of the other type moving from forward to aft and the cord of the fins of the second type is smaller than the cord of the fins of the first type.

A grating for forming a reverse flow of a turbofan engine having a forward longitudinal end and an aft longitudinal end and a lateral width, the grating comprising:

fins of a first type having a curved profile when viewed in a lateral direction relative to the grating, a rounding of the curved profile being configured to be oriented aft and whose center of curvature is forward relative to the fin of the first type,
fins of a second type, wherein a chord of the fins of the second type is smaller than a chord of the fins of the first type,
wherein the fins of the first type and the fins of the second type are disposed in an alternating arrangement along the grating, and
wherein each fin of the second type has a curved profile when viewed in a lateral direction relative to the grating, a rounding of the curved profile being configured to be oriented aft and whose center of curvature is forward relative to the fin of the second type.
