USCLPL Balerion Engine Test Ends in Flames

Not all the flames went the direction they were supposed too!

The Balerion engine is 3D printed from Inconel 718, using a LOX/kero propellant combination and produces 10,008.5 N (2250lbf) of thrust. USCLPL has partnered with the Kyushu Institute of Technology (Kyutech), Japan to provide the engine for their winged reused sounding rocket project #13.

You can read more of the engine technical details here.

A great video lecture on Liquid Rocket Engine Sizing from USC LPL.

If you are struggling to get through the basics of Rocket Propulsion Elements, then this presentation is great to have on while flicking through the book!

Why Rocket Exhausts Look The Way They Do

I have read and been told, a good engineer can tell a lot about how the rocket engine is running by just looking at the exhaust.
Scott Manley goes into some good detail on why rocket engine exhausts look the way they do.

Video Caption: Why does the exhaust from the Space shuttle boosters & engines look completely different? There’s a huge variety in the appearance of rocket exhausts because different fuels, different technologies and different environments make them behave in a different manner.
