Back with another static engine test of an #SRAD micro-liquid #rocket #engine designed and researched by #students.
The #nozzle of the engine is made of aluminum alloy and is powered by ethanol and compressed air. In this test, we used "the most scientific temperature measuring technique"βthe #marshmallowtest
The results were surprising, to say the least. We found that you definitely don't want to put your hand in the exhaust of a rocket, even if you don't see a flame, as the temperature can reach up to 2000Β°C.
Additionally, we noticed a fascinating and somewhat concerning greenish flame at the end of the engine. In terms of efficiency, the rocket's #performance was somewhat negative, but we believe that using nitrous oxide and methanol instead of a colossal amount of compressed air and some ethanol could yield better results in the next iteration of the engine and of course a better ignition system!
And let's not forget, this rocket could also double as a marshmallow roaster! https://youtu.be/dM_Ymi_zLxI
