The Comparison of Medieval Gunpowder Explosives toward Modern Day Plastic Explosives

plastic-explosiveDuring the modern day, soldiers use plastic explosives to blast through walls, similar to that of the gunpowder powered cannons of antiquity, but different in the sense that they can be directly applied and finely controlled. Despite these differences, the principle of both weaponry remains the same which is to create a powerful burst of kinetic energy to smash apart solid structures. Soldiers with explosive expertise during the modern day plant explosives in a lowercase “i” or “t” shape format by separating the explosives with a gap in the middle. This design ensures the explosive will blow a hole in the top and the bottom of the blast site, as well as the sides in some instances, leveraging the physics of the shockwaves produced to disrupt the wall and weaken it in the middle. Explosive experts don’t attach plastic explosives at the bottom of walls for two distinct reasons, the first being because the foundation upon the other side of the wall which cannot be viewed has the potential to be higher than the foundation facing the impending soldiers, which means that the explosives would be blasting into solid ground soil which is much less effective than blasting into walls made of concrete or otherwise, and the second being that explosives close to the ground create rubble directly next to the hole created, making forced entry more difficult, especially under siege conditions with active enemy combatants attempting to stop the breach. The main difference between Medieval gunpowder and modern day plastic explosive is the amount of material required to produce the same effect as plastic explosives are an entire order of magnitude more powerful than gunpowder, with 2 kilograms of plastic explosive equating to multiple barrels of gunpowder. Explosives are categorized as either “high explosives” or “low explosives” with high explosives having the front of the chemical reaction travel faster than the speed of sound and low explosives having the front of the chemical reaction produced travel slower than the speed of sound. To provide comparison, modern day C4 plastic explosives have a detonation velocity of 8,092 meters per second whilst gunpowder has a detonation velocity of just 171 – 631 meters per second
