1. **Wireframe of the turbine section. The outer diameter is 82 mm.

2. **Deformation due to 110000/min of rotational speed. The
amplification factor is set to 20.

**Picture
3. **Von Mises stress due to 110000/min rotational speed.
Plastification is considered but no creep had taken place. The values
along the blade-root are uncertain because the fillet-radius is not
modeled.

4. H**eat transfer coefficients, calculated with duns (CFD) based
on a simplified 3D-model and interpolated to the fe-model

**Picture
5. **Steady state temperature distribution used for the burst and
creep calculations using the above shown heat transfer coefficients.

6. **Equivalent plastification vs. rotational speed. Save operation
is possible below 180000/min.

**Picture
7. **Equivalent plastification at the last converging time-step of
the burst calculation at about 215000/min.

**Picture
8. **Equivalent creep strain in the blade over 100 h of operation
at 110000/min. CalculiX provides an interface for user-written
subroutines which was used for this calculation.

9. **Equivalent creep strain after 100 h of operation at 110000/min

10. **Frequency diagram of the turbine-blades. Resonances with the
vanes can not be avoided. Stress stiffening due to the rotational
force and the increase in temperature with the rotational speed is
considered.

11. **Modeshape of the first bending mode with five nodal diameters
(1F-5ND). This mode could be triggered by the five hollow vanes used in the gas-turbine. For this
calculation the cyclic symmetry capabillity of CalculiX was used.
