This is my second rocket motor.
The first used potassium nitrate and sorbitol. This motor uses potassium nitrate and erythritol. It doesn't absorb moisture from the air once cooked, and the slower burn rate allows for greater core-to-nozzle throat ratios. It has proven to be harder to ignite, so I need to work on that. I do like the castability of the fuel, it pours well with 1% glycerine added and there were no voids.
Повторяем попытку...
