Patent number: 7399164Abstract: A turbine engine and a rotor for a turbine engine are provided. Several adjacent turbine blades are positioned in the circumferential direction of the rotor, each turbine blade having a blade root, each turbine being fixed in a retainer groove, running in the circumferential direction of the rotor, by means of the blade root. Each turbine blade may be introduced, by the blade roots thereof, into the retaining groove, by means of a filling groove, whereby the width of the filling groove is matched is matched to the width of the blade roots. The width of the blade roots (13, 14) and the width of the, or each filling groove (17) in the circumferential direction is greater than half the width of a desired nominal blade pitch (18), whereby in the region of the, or each filling groove (17), a first number of turbine blades (11) with desired nominal blade pitch (18), is exchanged for a second number of turbine blades (12), with increased blade pitch (19), the first number being greater than the second number.Type: GrantFiled: October 2, 2004Date of Patent: July 15, 2008Assignee: MTU Aero Engines GmbHInventor: Richard Scharl
