the open-source turbomachinery designer

Axial Shaft

Axial Stage Casing

Turbodesigner is a tool that given parameters such as pressure ratio and mass flow rate can generate designs using mean-line design, blade flow analysis, and at the end generate a CAD model that can be exported to STL and STEP files.

Currently this generates axial compressors and with further tweaks axial turbopumps for liquid rocket engines

To avoid feature creep or due to lack of development the following assumption are made:

• Turbomachinery is an axial compressor (will suport more in later versions)
• FlowStation assumes an Ideal Gas
• Mean line is constant and is based on hub to tip ratio
• Blade calculations are base on the mean (rm) station
• Stagger angles are generated with FreeVortex (will support more in the future)
• Blade airfoil is only a Double Circular Arc at the moment since other geometries haven't been implemented
• incidence (i) and deviation (delta) values are defaulted 0 (will get Johnson Method working, but at the moment it is disabled)

There are plans later to make the classes that make calculations extendable for certain circumstances
