Pretty darn good! The first white steam and oxygen jet lasted too much before ignition when the fuel kicked in... But thats a great propulsion yield. Also all the temperature sensors showed a little rough vibration but nothing that a careful fuel and oxidizer mixing wont fix. What are you using to avoid burning instability? Or... I suppose at this scale that doesnt surface as a problem.
@@romoalex concentration and chamber pressure are pretty basic design parameters. besides i recognize this project from papers I've read. These guys are based out of Korea (KAIST I think?) and they've published a few papers notably "Effects of Transverse Jet Penetration on High-Test Peroxide/Kerosene Bipropellant Thruster" and "Performance Characteristics of Hydrogen Peroxide/Kerosene Staged-Bipropellant Engine with Axial Fuel Injector" which indicate a baseline engine design for 90% h2o2 concentration and 30 bar chamber pressure.
SO silent and great stability

Yes, good work.
Wow
Extremely cool. But you're not getting good htp decomposition.
Hello Guys,
What is a concentration of HTP you used with what chamber pressure?
sure like theyre going to just reveal their years of work and research in the comments

what are the dimensions and flow rate?
how is the combustion chamber cooled?
nice run
Very nice! !
