Safe temperatures |
The burning rate of propellant powders changes with temperatures and pressure - the higher temperatures and pressures causing more rapid burning. If rockets are fired at temperatures higher than those for which they are designed, the pressure may build up faster than the nozzle can release it, perhaps bursting the round. At temperatures below the safety limit, there will be back blasts of flame with burning fragments of powder. |
