Can ethanol be used as rocket fuel?
Nitrous oxide and ethanol were shown to perform well as rocket propellants, with specific impulses experimentally measured in the range of 250 to 265 lbf-sec/lbm at ground level operating conditions.
How do ethanol rockets work?
The small amount of fuel is vaporised and mixes with the oxygen in the air and is then ignited. The combustion produces carbon dioxide and water vapour and energy in the form of heat. The heat causes the gas inside the bottle to expand, forcing the gas through the rear nozzle at high speed.
Is alcohol a good rocket fuel?
Kerosene. The V-2 rockets developed by Nazi Germany used LOX and ethyl alcohol. One of the main advantages of alcohol was its water content which provided cooling in larger rocket engines.
Can you run a car on pure ethanol?
However, most cars don’t run on pure ethanol – in fact, running on higher than 15-20% ethanol concentration can cause engine damage because the engine has to be adjusted to account for the differing combustion property of that concentration.
Does ethanol burn faster than gasoline?
The drop in fuel economy is because ethanol has lower energy content per gallon than gasoline. E85 also burns faster than regular gasoline because it vaporizes faster. So your engine may eat through E85 faster than regular gasoline.
How do you make homemade rocket fuel?
To make rocket fuel, start by mixing potassium nitrate and sugar in a container. Then, transfer the mixture to a saucepan and add some Karo syrup and water. Next, heat the ingredients over medium heat for 5 minutes, stirring it constantly as it thickens.
Is water or air a better propellant for a bottle rocket?
Before launch, the bottle is filled with some amount of water, which acts as the “propellant” for the launch. Since water is about 100 times heavier than air, the expelled water produces more thrust than compressed air alone.
How do soda bottle rockets work?
A launcher powered by a hand bicycle pump or small compressor fills a plastic pop bottle rocket with compressed air. When the bottle is released from the launcher, air escapes the bottle. As the bottle pushes out the air, the air pushes the bottle upwards (Newton’s Third Law of Motion).
Is ethanol a moonshine?
After fermentation, moonshine is distilled to concentrate the ethanol and other volatile flavor ingredients. However, ethanol boils at 173.1 degrees Fahrenheit (78.37 degrees Celsius), while methanol boils at 148.5 degrees F (64.7 degrees C).
Can you run an engine on pure ethanol?
Pure ethanol – 100% ethanol or E100 – could theoretically be used to power cars, but generally isn’t, for numerous reasons: Ethanol is bad for cold-starting, because it doesn’t burn as quickly as gasoline. (It has a higher octane, if you’re interested.) Pure ethanol would be useless as fuel in the winter months.
What makes a bottle rocket go higher?
When the bottle is released from the launcher, air escapes the bottle. As the bottle pushes out the air, the air pushes the bottle upwards (Newton’s Third Law of Motion). Increasing the thrust (adding more pressure to the bottle) increases the acceleration.
Can ethanol be used as a rocket fuel?
Ethanol as a Rocket fuel? Wondered if Ethanol would be a good mix into RP-1 for a Rocket fuel. Ethanol delivers decent heat energy (octane in auto terms). E85 used in America works very well in US auto’s. I’ve seen some talk of Methane engines etc. Well Ethanol can be processed out of methane, so is it a better fuel?

How do you make a rocket out of an ethanol bottle?
Place the bottle on the ramp with the base facing the bottom of the ramp. Light the rocket by holding a lit splint attached to a metre rule next to the hole in the bottle. The rocket will fly around 15 m through the air with a high pitched hiss. Any spare ethanol can disposed of down the sink, followed by plenty of water, before firing the rocket.
What would happen if you drank alcohol fuel from a rocket?
If the crews drank the alcohol rocket fuel, they’d get violently nauseaus and puke their guts out… The follow on to V-2, Redstone, used alcohol as fuel. The theoretical ISP is pretty low, though, and so kerosene and other fuels with better ISP soon replaced it.
