摘要
The invention relates to a gas-turbine blade ring (90) having a supporting structure (80) and gas turbine blades (50) fastened thereto. The gas turbine blades have a blade root (52), adjoining which one after the other are a platform (54) and then a blade profile (56) curved in the longitudinal direction (L), wherein the blade root (52) runs in the longitudinal direction (L) of the blade profile (56), and the platform (54) has two platform longitudinal edges (55) running in the longitudinal direction (L) and curved in parallel. In order to specify an alternative gas-turbine blade ring (90) with simplified fitting, it is proposed that the blade root (52) be formed in such a way that the suction-side or pressure-side blade root surface (72) of the relevant platform longitudinal edge (55) is curved convexly or concavely, respectively. In addition, the invention relates to the use of such a gas-turbine blade ring (90).
