Title: MODULAR TURBINE BLADE HAVING A PLATFORM
Abstract:
The invention relates to a turbine blade (10) comprising a blade (12) and a modular platform (13) which follow one another along a longitudinal axis (11) of the turbine blade (10). According to the invention, in order to provide a modular turbine blade (10) that has an especially plain and simple design and that ensures an especially reliable, long-lasting, durable connection of the individual components among each other, the blade (12) has an extension (26) and the platform (17) comprises an outer platform part (15) and an at least two-part inner platform part (13) which is radial in relation to the longitudinal axis (11) and which lie laterally against the extension (26) of the blade (12), and the outer platform part (15) is designed as an endless platform frame (18) that surrounds the outer edge of the inner platform part (13).
