SUMMARY

The recommended burn temperature for G2 model rocket engines, specifically when using ethanol as fuel, is best determined by contacting the manufacturer for the precise 'flame temperature' or 'adiabatic flame temperature.' The discussion highlights the importance of knowing the chemical composition of the fuel to provide an accurate approximation. For a single-stage rocket with a 3-inch diameter and one gallon of ethanol, the estimated altitude is around 17,000 feet.

PREREQUISITES
  • Understanding of model rocket engine types, specifically G2 engines.
  • Knowledge of combustion chemistry, particularly regarding ethanol as a fuel.
  • Familiarity with rocket design principles, including dimensions and staging.
  • Ability to interpret technical specifications from manufacturers.
NEXT STEPS
  • Research the specific flame temperature of ethanol for accurate combustion data.
  • Contact G2 engine manufacturers for detailed specifications on burn temperatures.
  • Explore rocket design software to simulate performance based on fuel type and dimensions.
  • Study the effects of different fuels on model rocket performance and safety.
USEFUL FOR

Hobbyists and engineers interested in model rocketry, particularly those building rockets with G2 engines and using ethanol as fuel.

Hey guys,
I am new here. A firend and I have decided to build our own rocket. adn we were wondering if any of you knew what the brun temp. in celsius was for a model rocket engin. We are looking at the G2's. any help would be great here. thanks a lot!

A quick google search isn't giving any results.

Your best bet would probably be to contact the manufacturer. You'll be asking what the 'flame temperature' or 'adiabatic flame temperature' is.

If you know the chemical composition, I may be able to come up with a first cut approximation for you if that doesn't work.
 
We are thinking about using eathanol. with a gallon of fuel, and a 3" diameter... single stages estimates are around 17,000 feet so that's what we want to do.
