DAWN FOR AIRCRAFT TURBOMACHINE RECEIVER, PROVIDED WITH TWO HOLLOW AMES SUCCESSFUL ACCORDING TO THE SKELETON

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).
