From Prototype to Progress: Cryogenic Turbopump Tests

Описание: Testing is coming to an end for our in-house #Turbopump now implying cryogenic fluid ❄️ at our Titan Research & Test Center.

As a critical component of our launcher's propulsion system, the turbopump ensures optimal performance by supplying each Navier #RocketEngine with the right propellant flow and pressure ⬆️🔥⬆️ Such a hardware gives us full control over the launcher's #Propulsion system, allowing it to be more flexible and affordable to a variety of #SmallSats launch missions ✅

Now that initial tests are achieved, we have transitioned to testing with liquid oxygen (LOx), a far more challenging cryogenic fluid ⚠️ Managing LOx requires precision to prevent gas formation and avoid cavitation, a phenomenon that could impact the turbopump’s efficiency.

Another key focus of the campaign is verifying the turbopump’s mechanical resilience under extreme temperatures🌡️ We are also analyzing the output to ensure consistency of flow rates and pressures, as well as validating the system's seal integrity between LOx and lubricants 📈📊✅ To enhance safety during this phase, RP1 is not yet introduced.

The data collected from these tests have enabled our #FluidAndPropulsionSystems team to improve the design of the flight-ready turbopump 🔄 🔜 This updated version is currently being directly integrated into the Navier engine flight combustion chamber for upcoming testing on another dedicated #TestBench.

We would like to thank ‪@CnesFrance‬ for their incredible expertise and advice 🙏
