apart from conventional ceramics the use of advanced fiber reinforced ceramics is also possible which are far better protected from damaging effects in particular of a mechanical nature the shell shaped configuration of the ceramic front edge 3 is well suited to the design having fiber reinforced ceramics in order to understand it better the front edge section 2 of the blade 1 is considered again in fig2 to a larger scale and in so far as necessary is described further fig2 shows the front edge section 2 of the blade 1 as already largely described under fig1 the construction of the hung ceramic front edge 3 as well as the means 6 and 5a 5b respectively provided for this for producing the coupling and a frictional connection and or positive locking connection between the two parts 3 4 are clearly apparent from this figure fig3 shows the ceramic front edge already described under fig1 and 2 in a three dimensional view which ceramic front edge is itemized here by 20 on account of its specific design if the radial stresses occurring inside this ceramic front edge 20 in the fitted state should become too great this can be remedied by the ceramic front edge 20 being split into two or three in the radial direction in which case special measures then have to be provided at the hanging mechanism for the various parts the division of such a ceramic front edge.
