Abstract
A cascade element for a thrust reverser system of an engine, more particularly a jet engine, comprises a number of mutually adjacent deflecting vanes for deflecting an air flow, at least one of the deflecting vanes being twisted about its longitudinal axis at least along a twist longitudinal portion, and an engine having a cascade element of this type and to a method for producing a cascade element of this type, wherein additive manufacturing is carried out.
Claims17
A cascade element for a thrust reverser system of an engine, comprising:
- a number of adjacently arranged deflecting blades for deflecting an airflow,
- wherein at least one of the deflecting blades is twisted about its longitudinal axis at least along a twisting longitudinal section, and
- wherein at least one deflecting blade comprises a bulge on an edge delimiting the deflecting blade in a direction of downward extent, so that a shape of the edge deviates from a straight line or, in the twisting longitudinal section, from a helix.
An engine having a thrust reverser system, wherein the thrust reverser system comprises at least one cascade element, the cascade element comprising:
- a number of adjacently arranged deflecting blades for deflecting an airflow,
- wherein at least one of the deflecting blades is twisted about its longitudinal axis at least along a twisting longitudinal section, and
- wherein at least one deflecting blade comprises a bulge on an edge delimiting the deflecting blade in a direction of downward extent, so that a shape of the edge deviates from a straight line or, in the twisting longitudinal section, from a helix.
A method for producing a cascade element for a thrust reverser system of an engine, comprising:
- additive production of a number of adjacently arranged deflecting blades for deflecting an airflow, wherein at least one of the deflecting blades is constructed with a twist with respect to its longitudinal axis along a twisting longitudinal section, and wherein at least one deflecting blade is constructed with a bulge on an edge delimiting the deflecting blade in a direction of downward extent, so that a shape of the edge deviates from a straight line or, in the twisting longitudinal section, from a helix.
