Its final fall was due to the introduction of gunpowder as a propellant.
The suit had been torn in the fall, and some propellant had gotten in through the rents.
Compressed air was the propellant for the Zalinski dynamite gun.
The propellant was taking the rocket almost out of sight when the fuse fired it.
Rick looked up in time to see the rocket split wide open and most of the remaining tons of propellant gush out.
For instance, the one which drives the shell from the gun, known as the propellant, must not be too sudden in its action.
In army usage the term "propellant" includes both smokeless powder and black powder.
It is desired that a propellant shall produce the maximum velocity with the minimum pressure.
Some jerk has redesigned the primer so that the flame misses the propellant!
Clearly, smoke, which is most objectionable in the propellant, is a positive advantage in the bursting charge.
