- TL;DR Summary
- Is it that what increases propellants' specific impulse makes it proportionally a more powerful gun propellant?
Black powder has specific impulse of around 80s, while rocket candy has up to 130s of specific impulse. Does that mean I could replace the propellant in a BP cartridge with 80/130 of the weight in rocket candy and obtain the same performance in an idealized gun? (as in without considering burnrate, peak pressure and pressure vs time dependence)
Or is it that what increases propellants' specific impulse isn't making it proportionally a better gun propellant?
