The jet engine was build around a turbo-charger rotor in the early 90’s by Andreas Funke and Klaus Wittig.

Click HERE for the jet-engine-model and documentation. Anyone for making an importer into valculix animation workbench? Open the results with cgx and there type Code: Read more about what I do at my blog. Static, dynamic and thermal solutions are available. Like my FreeCAD work?

The method used is the finite element method. The FE-model was build from scratch with CalculiX and the compressor- and turbine models together with solver input files can be found in the distribution. The driving force is gravity. Click HERE to see the example of the turbo-charger compressor. The surface behavior parameter is way off from the recommendation in the Calculix manual. The contact feature did need tuning. Contact information can be found at the bottom of the “Download” page.


The rigid body concept is used to fix the two bodies in space. After some trial and error I got a working bouncing pendulum with just two finite elements. So I tried to find out, if it is possible to do some basic physics with it.

The input file is given together with two scripts, in order to create an animation with cgx. Click HERE to see the example of the turbo-charger turbine. Did not know that this is possible in CalculiX. In czlculix the eigenfrequencies were calculated to determine possible resonances with the vanes. CalculiX is a package designed to solve field problems.

Both programs can be used independently. The CalculiX package was developed by a team of enthusiasts in their raw spare time. Put all files into one directory. The right and left side of the disks are connected by cyclic symmetry equations which allow to calculate eigenvalues and mode-shapes calcu,ix certain nodal diameters of a rotational symmetric volume based only on a segment of the structure.

CalculiX FE-Model of a jet engine with turbo-charger compressor blue and turbine red. For a quick overview of the capabilities of CalculiX the results of an investigation calcullix a small jet engine are presented.

A simple step reader is included. The compressor is made of casted aluminum alloy AlSi – C and the turbine of a high temperature alloy Inco C.

One degree of freedom is left, so they can rotate about their fix-point. The solver is able to do linear and non-linear calculations.

The calculations were done to determine the burst-speed and the highest allowable rotational speed concerning low cycle fatigue and creep. You do not have the required permissions to calchlix the files attached to this post. The models are meshed with 20 noded brick elements with reduced integration.
