Terminal dash can be achieved by varying grain configuration in solid propulsion
There are three types of burns that can be achieved with different grains.
Progressive Burn
Usually a grain with multiple perforations or a star cut in the center providing a lot of surface area.
Digressive Burn
Usually a solid grain in the shape of a cylinder or sphere.
Neutral Burn
Usually a single perforation; as outside surface decreases the inside surface increases at the same rate.
