Vane for receiver of turbomachine e.g. turbojet engine, of aircraft, has structural hollow secondary core arranged at downstream of structural hollow main core and formed by using four longerons

摘要

The vane (200) has an aerodynamic shell covering a structural hollow main core (34) extending according to a wide span direction of a blade, where the main core is formed by using longerons (38, 40, 42, 44). A structural hollow secondary core (34') is arranged at downstream of the main core. The secondary core is formed by using a first longeron (38') oriented to a leading edge (26) of a shell, a second longeron (40') oriented towards a trailing edge (28) of the shell, a third longeron (42') oriented towards an intrados (30) and fourth longeron (44') directed towards an extrados (32).
