I'm going to assume you mean that the fuel is not routed around the nozzle to cool it and instead its just using some crazy material to do it.

[@fork9001]

@@Nefville Ablative material, these types of materials flake off when heated to extremely high temperatures, preventing the nozzle from overheating. Same thing is used on the heat shields for every spacecraft that enters an atmosphere so far with the exception of the space shuttle and Buran that uses non-ablative tiles.

Using Ethanol as primary rocketfuel could be quite useful in the future, because supply of alcohol sure won't go down, while RP1 is made out of Diesel which is basically made of oil. So this is even more awesome than just a rocketengine firing!

[@xenotriver]

Or you can just use methane, and produce it with carbon and hydrogen

[@spencer6104]

Ethanol gets gooey in the cold. Not good for a vacuum. Methane is generally a more accepted future renewable fuel, but alcohol rockets could be possible.

[@paulmarchi1393]

It's much less efficient than methane/lox and of course hydrolox though

[@paulmarchi1393]

@@chriseffpunkt4333 Wow relax. Methane and hydrogen are both common and aerospace companies have literally no reason to make large scale ethanol engines due to their immensely lacking efficiency. Their only benefit is that they are easier to design so they can be used to learn to make an engine before moving on to more powerful propellant combinations.

[@makssachs8914]

Ethanol is quite bad as fuels go though and we have better alternatives. For one, theres Methalox and secondly we can use hydrolox first stage engines like the RS-25.

[@Zodliness]

I'm curious to know how much fuel is consumed during one of these tests and the final nozzle temperature?

[@florinmingireanu2843]

Probably around 430-450 kg of propellant (oxidizer+fuel); ball park estimation using the stated 80 seconds of burn-time.

[@Zodliness]

@@florinmingireanu2843 That would equate to around 5.6Kg per second flow rate over an eighty second burn. Drag cars drink through a gallon a second around (3.79Kg) per second! Rocket Boosters consume 11,000 pounds of fuel per second.

[@florinmingireanu2843]

@@Zodliness 12 kN (12,000 Newtons thrust) rocket engine with the abovementioned burn-time (80 seconds) and the LOX/ethanol propellant mixture is expectedto consume 430-450 kg of propellant (O+F) which in turn indeed means an average of 5.375-5.625 kg/s. Of course, this consumption is valid for an average range of specific impulse. Did you detect any errors in my calculation?
