  • Patent number: 11365637
    Abstract: A method for profiling blades of an axial turbomachine includes preparing a geometric model of a blade profile; determining an oscillation mode of the geometric model; calculating a time profile of a position-dependent disruptive pressure in a channel between two adjacent blade profiles over an oscillation period of the oscillation belonging to the oscillation mode, changing the geometric model and determining a different oscillation mode for the modified geometric model; and determining the damping of the oscillation using the disruptive pressure profile calculated previously and accepting the modified geometric model for the case that the damping of the oscillation turns out to be greater than calculated, otherwise repeating the last two steps with another modified geometric model.

  • Publication number: 20210271789
    Abstract: A method for designing a turbomachine vane, in which predefined input parameters are transmitted to a neuronal network system and vane parameters are determined and output by the neuronal network system based on the transmitted input parameters. The neuronal network system has several separate neuronal networks each with an output layer, each of which determines one or more of the vane parameters and outputs same via the output layer. A first neuronal network and a second neuronal network belong to the separate neuronal networks of the neuronal network system and the vane parameter(s) which are determined by the first neuronal network and output via the output layer of said neuronal network differ(s) from the vane parameter(s) that are determined by the second neuronal network and are output via the output layer of said neuronal network.

  • Patent number: 10563511
    Abstract: A method for profiling a turbine rotor blade for an axial flow machine, having the following steps: providing a geometric model of a blade profile, having a camber line of a profile section of the turbine rotor blade; determining boundary conditions for a flow flowing around the turbine rotor blade; changing the camber line such that the flow which is adjusted by the boundary conditions produces the maximum of the difference of the isentropic mach number between the pressure side and the suction side of the turbine rotor blade in a blade section which extends from the blade trailing edge in the direction towards the blade leading edge and the length of which is 65% of the length S of the blade chord.
