  • Fin stabilizer and watercraft
    Patent number: 9745031
    Abstract: A fin stabilizer for stabilizing a watercraft against rolling movements includes a main fin configured to be pivoted by a watercraft-side fin drive, a tail fin, and an elastically deformable connection between the main fin and the tail fin, the elastically deformable connection being configured to flex whenever a water force acting on the tail fin is greater than a predetermined amount.
    Type: Grant
    Filed: August 27, 2015
    Date of Patent: August 29, 2017
    Assignees: SKF Blohm + Voss Industries GmbH, Deutsches Zentrum für Luft- und Raumfahrt e. V. (DLR)

  • Method for producing components with a high load capacity from TiAl alloys
    Patent number: 6997995
    Abstract: The invention relates to a method for producing components with a high load capacity from ?+? TiAl alloys, especially for producing components for aircraft engines or stationary gas turbines. According to this method, enclosed TiAl blanks of globular structure are preformed by isothermal primary forming in the ?+?? or ? phase area. The preforms are then shaped out into components with a predeterminable contour by means of at least one isothermal secondary forming process, with dynamic recrystallization in the ?+?? or ? phase area. The microstructure is adjusted by solution annealing the components in the ? phase area and then cooling them off rapidly.

  • Method for producing components with a high load capacity from tial alloys
    Publication number: 20040094248
    Abstract: The invention relates to a method for producing components with a high load capacity from &agr;+&ggr; TiAl alloys, especially for producing components for aircraft engines or stationary gas turbines. According to this method, enclosed TiAl blanks of globular structure are preformed by isothermal primary forming in the &agr;+&ggr;− or &agr; phase area. The preforms are then shaped out into components with a predeterminable contour by means of at least one isothermal secondary forming process, with dynamic recrystallization in the &agr;+&ggr;− or &agr; phase area. The microstructure is adjusted by solution annealing the components in the &agr; phase area and then cooling them off rapidly.
