FIELD: engines and pumps.
SUBSTANCE: method of cellular seal fixation in gas turbine engine stator main frame consisting of cellular assy and case fitted in turbine stator main frame. Special grooves and through cutouts are made in said main frame. Pins are fitted in said cellular seal. Cellular seal is fixed by turning it relative to stator main frame in direction of turbine rotor rotation unless said pins go against the stop on special surface on said main frame and locked by shaped plate washers fitted in main frame groove before fitting cellular seal in place. Then they are bent over seal case end and turbine stator main frame.
EFFECT: higher reliability and quality of assembly, ease of assembly and repair, lower labor input.
