SPL welcomes Devis Tonon in it’s team

We welcome Devis Tonon as a new team member. He holds a PhD in Applied Physics (Technical University of Eindhoven) and a MSc in Aerospace engineering (Polytechnic University of Turin). He has experience in aeroacoustics, thermoacoustics and fluid dynamics. He will be a great help for us solving the thermoacoustic issues in one of our engines.

10 kN engine at full throttle, modification on test stand

Short summary: The engine ran on Ethanol/LOX, O/F about 1.95, thrust nearly a metric ton and we got a (measured!) ISP of about 232s at a chamber pressure of 21 bar… which is quite a good number! We pushed the chamber pressure further, but ended up with a molten nozzle (for optimizing combustion, short burning times are sufficient… so we only use mild steel nozzles at this state of the tests).
