Stator of a high-pressure turbine of a turbomachine, and a method of assembling it

A stator of a high-pressure turbine of a turbomachine comprising the following elements:

• an annular casing disposed about a longitudinal axis of the high-pressure turbine;
• a plurality of spacers that are sectored and mounted on the casing and onto which a plurality of ring sectors are secured, said ring sectors being disposed circumferentially about the longitudinal axis of the high-pressure turbine so as to form a continuous circular surface encompassing the rotor blades of a high-pressure turbine rotor;
• a plurality of angular air flow duct sectors disposed circumferentially around the casing and designed to discharge air onto the casing in order to enable clearance at the tips of the high-pressure turbine rotor blades to be tuned;
• and
• a plurality of air supply inlets disposed through the casing and designed to supply air to a low-pressure distributor stage of the turbomachine, said stage being disposed downstream from the high-pressure turbine;
• said stator being wherein the stator elements are distributed angularly about the longitudinal axis of the high-pressure turbine so as to prevent the inter-spacer zones defined between two adjacent spacers being in radial alignment with the duct inter-sector zones defined between two adjacent duct sectors.
