Title: DIMENSIONING OF THE SKELETON ANGLE OF THE TRAILING EDGE OF THE ARMS CROSSING THE BYPASS FLOW OF A TURBOFAN
Abstract:
The invention relates to a part (1) or an assembly of parts of a splitter stage of a turbofan, comprising a plurality of obstacles (4, 5, 6a, 6b) including at least one a blade (4) and at least one arm (5, 6a, 6b), and a platform (2) from which the obstacles (4, 5, 6a, 6b) extend, characterised in that said arm (5, 6a, 6b) is defined by a skeleton angle having a trailing value on the trailing edge (BF) of between 3° and 15°.
