Strut for an intermediate turbine housing, intermediate turbine housing, and method for producing an intermediate turbine housing

A strut for a turbine center frame of a jet engine having a turbine center frame, a housing and a strut casing, the strut comprising:

• a first end for connection to an internal structure of the turbine center frame;
• a second end, disposed opposite the first end, for connection to the housing;
• wherein the second end includes
• a flange-like element having at least one first aperture for accommodating a first attachment element for connecting the flange-like element to the housing;
• a flange having at least one second aperture for accommodating a second attachment element for connecting the flange to the housing;
• and
• wherein the flange-like element is removably connectable to the flange such that, when the flange-like element is connected to the flange, a strut casing may not pass over the flange toward the first end of the strut, but when the flange-like element is not connected to the flange, the strut casing may pass over the flange toward the first end of the strut.

A turbine center frame for a jet engine having a housing and a plurality of strut casings, the center frame comprising:

• an internal structure;
• a plurality of struts, each strut connected at a first end to the internal structure and having a second end radially disposed therefrom for connection to a housing;
• wherein the second end of each strut includes
• a flange-like element having at least one first aperture for accommodating a first attachment element for connecting the flange-like element to the housing;
• a flange having at least one second aperture for accommodating a second attachment element for connecting the flange to the housing;
• and
• wherein the flange-like element is removably connectable to the flange such that, when the flange-like element is connected to the flange, a strut casing may not pass over the flange toward the first end of the strut, but when the flange-like element is not connected to the flange, the strut casing may pass over the flange toward the first end of the strut.

A method for producing a turbine center frame of a jet engine having a housing and a plurality of strut casings, the method comprising the following steps:

• a) providing an internal structure of a turbine center frame and a plurality of struts, each strut connected at a first end to the internal structure and having a second end radially disposed therefrom for connection to a housing, wherein the second end of each strut includes a flange-like element having at least one first aperture for accommodating a first attachment element for connecting the flange-like element to the housing and a flange having at least one second aperture for accommodating a second attachment element for connecting the flange to the housing, and wherein the flange-like element is removably connectable to the flange such that, when the flange-like element is connected to the flange, a strut casing may not pass over the flange toward the first end of the strut, but when the flange-like element is not connected to the flange, the strut casing may pass over the flange toward the first end of the strut;
• b) assembling at least one strut casing on each individual strut, the assembly being performed radially from outside when the corresponding flange-like element are not connected to the flanges;
• c) connecting the corresponding flange-like elements to the flanges;
• and
• d) connecting the second ends of the struts to the housing.
