FIELD: foundry, possibly manufacture of blades of aircraft gas turbine small-size engines and of engines of ground mounted aggregates.
SUBSTANCE: plant includes ceramic mold having starting cavity, blade cavities and seed cavity communicated with starting cavity. System of horizontal and vertical gating having relation of their cross section areas in range 1 : (1 - 2) provides smooth melt supply to each blade cavity.
EFFECT: improved quality of cast blades, less loss of yield by structure of cast blades, enhanced efficiency of process.
