A plate (10) closing the main part (5) of a two-part blade. An internal cavity (8) is closed by the plate (10). Around the bearing surface (12) of the plate (10), a groove (14) receives a resilient seal (11), and the outer edge (29) of the plate (10) extends over the groove (14) to compress the seal (11) and ensure excellent leakproofing. The position of the plate (10) can be ensured by centring pins which penetrate into holes adjacent to the seal (11) which then fills them when the pins have been removed, thus completing the closure of the cavity (8). Application: in particular for stationary gas straightening vanes in turbine engines. |
