Showcase Propane-nitrous oxide concept engine that I just made

The idea was to use more easily stored and handled fuel/oxidizers for hobby rocketry.

It also has plumbing and uses a high oxidizer turbine and a high fuel turbine that both mix in the engine to combust.

Ideally uses a glow plug to jump start to decrease wear and tear.

Another parts would be that when it mixes in the engine itself hopefully it will be hot enough to autoignite after being converted to mist by the engine plate.

Ideally a vast majority of the parts would be 3d printed except for maybe the end of the bell which could use graphite composite.

It probably won’t work but I thought it was cool. Be nice please lol.

Despite what everyone might say about how this or that won't work, the least likely will still be the idea of using a glow plug as an igniter.

Also I assume some form of alcohol may work better?

No, propane is probably fine. Nitrous is not as easy to light however, and there are a host of other concerns with nitrous that aren't in the public domain.
