Vane for receiver of turbomachine e.g. turbojet engine, of aircraft, has blade part including aerodynamic shell that covers structural hollow core, and coatings respectively placed on two longeron outside structural hollow core

摘要

The vane (200) has a blade part (14) including an aerodynamic shell (24) that covers a structural hollow core (34) extending according to a wide span direction of a blade. The hollow core is formed by using a first longeron (38) oriented towards a leading edge (26) of the shell, a second longeron (40) oriented towards a trailing edge (28) of the shell, a third oriented (42) oriented towards intrados (30) and a fourth longeron (44) oriented towards an extrados (32) of the blade. Coatings (50, 52) are respectively placed on the first longeron and fourth longeron outside the hollow core. The coatings are made of shock absorber material that is foam, honeycomb structure material or absorbing gel.
