FIELD: gas-turbine engines. SUBSTANCE: packing member is used to seal clearance formed between two relatively movable hot parts with respective opposing groove of part. Packing member is primarily placed crosswise perpendicular to main line along center line; it is toothed structure that has first end, opposing second end, and intermediate area between them. Packing member is most suitable for sealing clearance between guide vanes at high temperature in gas- turbine unit to prevent ingress of cooling gas into hot-gas region.
