For miniature black powder rocket motors (13 mm diameter), the maximum thrust is between 5 and 12 N, the total impulse is between 0.5 and 2.2 N·s, and the burn time is between 0.25 and 1 second. For Estes ‘regular size’ rocket motors (18 mm diameter), there are three classes: A, B, and C.
A solid-propellant rocket or solid rocket is a rocket with a rocket engine that uses solid propellants (fuel/oxidizer). The earliest rockets were solid-fuel rockets powered by gunpowder . The inception of gunpowder rockets in warfare can be credited to the ancient Chinese, and in the 13th century, the Mongols played a pivotal role in ...
St. Marks Powder is a subsidiary of General Dynamics Ordnance and Tactical Systems manufacturing ball propellant [1] in Crawfordville, Florida. St. St. Marks makes about 6,000 tons per year, [ 2 ] making it the world's largest producer of propellant . [ 3 ]
Amateur rocketry was an especially popular hobby in the late 1950s and early 1960s following the launch of Sputnik, as described in Homer Hickam's 1998 memoir Rocket Boys. One of the first organizations set up in the US to engage in amateur rocketry was the Pacific Rocket Society established in California in the early 1950s.
Gunpowder is a low explosive: it does not detonate, but rather deflagrates (burns quickly). This is an advantage in a propellant device, where one does not desire a shock that would shatter the gun and potentially harm the operator; however, it is a drawback when an explosion is desired.
Igniferous time fuzes had a powder ring in an inverted 'U' metal channel, the fuze being set by rotating the upper part of the fuze. When the shell was fired the shock of firing set back a detonator onto a firing pin, which ignited the powder ring; when the burn reached the fuze setting, it flashed through a hole into the fuze magazine, which ...

Finnish smokeless powder. Smokeless powder is a type of propellant used in firearms and artillery that produces less smoke and less fouling when fired compared to black powder. Because of their similar use, both the original black powder formulation and the smokeless propellant which replaced it are commonly described as gunpowder.
