TURBINE ENGINE STATOR WHEEL AND TURBINE OR COMPRESSOR CONTAINING SUCH STATOR WHEEL Russian patent published in 2017 - IPC F01D9/04 F01D25/24 

FIELD: engines and pumps.

SUBSTANCE: turbine engine stator wheel comprises plurality of blades and metal assembly ring. Each of blades has internal platform, external platform having locking tabs from outside, and, at least, one aerodynamic surface extending between internal and external platforms. Blade and external platform together with locking tab form single element from composite material. In metal assembly ring blades locking tabs are engaged. Metal ring supports all blades, continuously extends along plurality of adjacent blades external platforms and forms separate assembly part between blades and housing. Other inventions of group relate to turbine and turbine engine compressor containing above mentioned stator wheel.

EFFECT: group of inventions enable to simplify turbine engine stator assembly comprising blades from composite material, as well as reduce leakages along blades external platforms.
