Turbomachine with an insert device that can be arranged inside a recess of a wall

Abstract

A turbomachine having a wall that extends circumferentially to a central axis of the turbomachine at least in certain areas, and having at least one insert device that can be connected in a releasable manner to a wall in the area of a recess which is arranged inside the wall. The insert device has a connection device by means of which the insert device can be brought into operative connection with a connection device of the wall. The connection device of the insert device has a projection that extends in the radial direction of the turbomachine at least in certain areas in the mounted state of the insert device, and that in the mounted state of the insert device meshes in a groove of the connection device of the wall. The connection device of the wall has a projection that extends in the radial direction of the turbomachine at least in certain areas in the mounted state of the insert device, and that, in the mounted state of the insert device, meshes in a groove of the connection device of the insert device.

         2 . The turbomachine according to  claim 1 , wherein the projection of the insert device or the projection of the wall has a surface which is also the surface of the groove of the insert device or the groove of the wall. 
     
     
         3 . The turbomachine according to  claim 2 , wherein the projection of the insert device and the projection of the wall are embodied in such a manner that the insert device can be brought in mesh with the wall in a translational motion. 
     
     
         4 . The turbomachine according to  claim 1 , wherein the wall and the insert device respectively have multiple projections and grooves. 
     
     
         5 . The turbomachine according to  claim 4 , wherein the grooves and the projections of the insert device and the grooves and the projections of the wall form a wave-shaped or a jagged profile in cross-section. 
     
     
         6 . The turbomachine according to  claim 1 , wherein the projection and/or the groove of the insert device and/or of the wall is or are arranged at the wall in a circumferential manner with respect to an edge area of the recess or at the insert device in a circumferential manner with respect to an edge area of the insert device. 
     
     
         7 . The turbomachine according to  claim 1 , wherein the insert device is retained at the wall in the area of the recess via at least one attachment means in the mounted position of the insert device. 
     
     
         8 . The turbomachine according to  claim 1 , wherein the insert device has a handle-like element at a radially outer side in the mounted position of the insert device. 
     
     
         9 . The turbomachine according to  claim 1 , wherein the insert device and the wall have a comparable structure in the cross-section and in particular are respectively embodied with a sound-absorbing middle layer, an inner layer, and an outer layer. 
     
     
         10 . The turbomachine according to  claim 9 , wherein the connection device of the insert device and/or the connection device of the wall are formed by the middle layer and/or the outer layer and/or the inner layer of the wall or of the insert device 
     
     
         11 . The turbomachine according to  claim 1 , wherein the projection of the insert device is connected to a web of the insert device, which, in the mounted position of the insert device, is arranged on a side of a web of the wall which is internal with respect to the radial direction of the turbomachine and via which the projection is connected to the wall. 
     
     
         12 . The turbomachine according to  claim 1 , wherein the wall has a frame structure that forms multiple recesses, wherein multiple insert devices are provided which respectively have a shape that substantially corresponds to a shape of a recess of the frame structure, and wherein each insert device can be brought into operative connection with the frame structure in the area of a recess in a releasable manner. 
     
     
         13 . The turbomachine according to  claim 12 , wherein the recesses of the frame structure and the insert devices are configured in a triangle-shaped manner. 
     
     
         14 . The turbomachine according to  claim 12 , wherein the frame structure of the wall completely surrounds an axial area of the turbomachine in the circumferential direction of the turbomachine. 
     
     
         15 . The turbomachine according to  claim 12 , wherein the frame structure forms only triangle-shaped recesses which can be brought into operative connection with respectively one releasable insert device.
