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.
Ammonium perchlorate composite propellant (APCP) is a solid rocket propellant. It differs from many traditional solid rocket propellants such as black powder or zinc-sulfur, not only in chemical composition and overall performance but also by being cast into shape, as opposed to powder pressing as with black powder. This provides manufacturing ...
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.
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.
The first smokeless powder was developed in 1865 by Johann Edward Schultze. At the time of this breakthrough, Schultze was a captain of Prussian artillery. Schultze eventually rose to the rank of colonel. His formulation (dubbed Schultze Powder) was composed of nitrolignose derived from nitrated wood grains, impregnated with saltpetre or barium ...
A British clockwork Time fuze for an artillery shell using the Thiel mechanism, circa 1936 British aluminium No. 25 Mk IV time fuze, using a burning gunpowder timer, circa 1914, used for star shells. Artillery Time fuzes detonate after a set period of time. Early time fuzes were igniferous (i.e. combustible) using a powder train.
The U.S. on Wednesday imposed new sanctions on hundreds of firms and people tied to Russia's weapons development program, more than a dozen Chinese firms accused of helping Russia find workarounds ...
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 ...
