FIELD: mechanical engineering; gas-turbine engines and their seals.
SUBSTANCE: proposed seal has first and second loops opposite in axial direction and permanently inter connected by coextensive bridge into common ring provided with ring slot. Two loops have arc-shaped sections with outer and inner sealing portions in radial direction. Bridge is located in radial direction between outer and inner portions. Loops are arranged in corresponding grooves of adjoining members to provide sealing and eliminate radial and axial temperature displacements.
EFFECT: improved sealing at different radial and axial displacements with large shift between components of gas-turbine engine stator.
