6. Conclusion

The rotating machine is a complex product that relies on a wide range of physics to deliver power at the lowest cost to the mass balance.

Design, production and operation are based on the experience and technical and project management know-how of the agencies and their industrial base, enabling us to master these physics in a product that ensures performance, repeatability and reliability under the environments and constraints typical of space.

Conditions specific to the cryogenic turbopump play an important role in the design of the machine, requiring specific skills, infrastructures and implementation methodologies, in order to design, test and operate the product.

Tools from the turbomachinery world represent an excellent starting point for design and analysis, but often need to be adapted and validated. Testing...
