Children: Ballistics
Internal ballistics is the study of the processes and phenomena that occur within a firearm or artillery piece from the moment the propellant is ignited until the projectile exits the barrel. This field encompasses various aspects, including the ignition of the propellant, the combustion of the propellant gases, the generation of pressure and temperature in the chamber, and the acceleration of the projectile as it travels down the barrel.
A light-gas gun is a type of experimental projectile launcher that uses a combination of gas and light to accelerate projectiles to very high velocities. It is primarily used in scientific research and testing, particularly in the fields of materials science, aerospace engineering, and ballistics. The concept of a light-gas gun was developed to simulate the conditions of high-speed impacts that materials and structures might experience during events such as space re-entry or impact from meteoroids.
Body armor performance standards are established guidelines that determine the effectiveness of ballistic and stab-resistant body armor. These standards help ensure that the armor can provide a specific level of protection against various threats. Here are some of the primary body armor performance standards: ### Ballistic Armor Standards 1. **NIJ Standards (National Institute of Justice, USA)**: - **NIJ 0101.06**: The most current standard for ballistic resistance of body armor.
The term "rangekeeping" is not a widely recognized term in mathematics or related fields as of my last update.
Muzzle energy refers to the kinetic energy of a projectile at the moment it leaves the barrel of a firearm or other launching device. It is an important concept in ballistics, as it helps to determine the potential effects of a bullet upon impact with a target.
The Muzzle Reference System (MRS) is a technology used primarily in the field of artillery and firearms to enhance targeting accuracy and efficiency. It is designed to help ensure that the weapon's aim is accurately aligned with the intended target by providing precise references for the gun's muzzle position. Key features of the Muzzle Reference System include: 1. **Positioning Reference**: It provides a reference point for the muzzle of the weapon, allowing operators to consistently and accurately position the gun for firing.
Muzzle velocity is the speed at which a projectile, such as a bullet or a shell, exits the barrel of a firearm or cannon upon firing. It is typically measured in meters per second (m/s) or feet per second (fps). Muzzle velocity is an important factor in ballistics, as it influences the projectile's trajectory, range, and penetration capability, as well as the overall accuracy of the firearm.
Overall length generally refers to the total length of an object from one end to the other. It is a term commonly used in various contexts, such as: 1. **Transportation**: In vehicles (cars, boats, aircraft), overall length denotes the total length of the vehicle as measured from the front bumper to the rear bumper. 2. **Construction and Architecture**: It can refer to the total length of a structural element, such as a beam or a building component.
The term "overbore" can refer to a few different concepts depending on the context, but it is most commonly used in the fields of mechanics and firearms, as well as in automotive and engineering discussions. Here are a few meanings: 1. **Firearms:** In firearms, "overbore" refers to a situation where a cartridge has a high powder capacity relative to the bore diameter of the rifle barrel.
In the context of weaponry and military technology, "penetration" refers to the ability of a projectile or weapon system to breach or penetrate a target's defenses, which often includes armor, fortifications, or other protective barriers. This term is especially relevant in discussions about armor-piercing ammunition, missiles, and other projectiles designed to overcome obstacles.
Piobert's Law, also known as Piobert's rule, relates to the absorption of light by a medium, specifically in the context of the absorption spectra of certain materials. It states that the absorbance of light by a substance is proportional to the concentration of that substance and the path length through which the light travels.
Point-blank range refers to the distance at which a projectile (such as a bullet) can be fired without accounting for the effect of gravity on its trajectory, allowing the shooter to aim directly at a target without needing to adjust for drop. In practical terms, this range is typically short, usually up to around 25 to 50 yards (or approximately 23 to 46 meters) for handguns and can vary based on the type of firearm and ammunition used.
A projectile is an object that is thrown, launched, or otherwise propelled into motion, often through the air, and continues to move due to its initial velocity and the influence of forces such as gravity and air resistance. Projectiles can come in various forms and can include anything from a thrown ball, a missile, an arrow, or even a spacecraft.
Projectile use by non-human organisms refers to the ability of certain animals to launch or propel objects as a means of predation, defense, or communication. Different species have developed various mechanisms for using projectiles. Here are some notable examples: 1. **Frog and Toad Species**: Some frogs and toads possess specialized tongues that can rapidly extend to catch prey, effectively using their tongues as projectiles. The tongue can be flicked out at high speeds to capture insects.
Propellant refers to any substance that can produce thrust through a chemical reaction or physical process, typically by expelling mass. It is commonly used in rockets, vehicles, and various propulsion systems. Propellants are classified into two main categories: 1. **Chemical Propellants**: These involve the combustion of fuels and oxidizers to produce hot gases that are expelled to generate thrust. Common examples include: - Liquid propellants (e.g.
QuickLOAD is a software program used for firearm cartridge reloading and ballistic calculations. Designed primarily for reloaders and gun enthusiasts, it allows users to simulate and analyze various aspects of ammunition loading, such as bullet performance, pressure levels, and velocities based on different powder types and weights, bullet types, and other factors. The program includes an extensive database of bullet and powder specifications, enabling users to create custom load recipes and evaluate their potential performance.
The range of a projectile refers to the horizontal distance it travels before landing on the ground after being launched into the air. The range depends on several factors, including the initial velocity of the projectile, the angle of launch, and the acceleration due to gravity.
The Reeves AN/TSQ-96 Bomb Directing Central (BDC) is a military system used for directing the delivery of munitions from aircraft to ground targets. It serves as an integrated command and control center, providing the necessary tools and information to coordinate and manage air support operations effectively. Key functionalities of the AN/TSQ-96 may include: 1. **Targeting Solutions**: Offering targeting data and solutions to pilots and ground commanders to ensure precision in munitions delivery.
The term "Ricochet" can refer to several different things depending on the context: 1. **Physics/Projectile Motion**: In physics, ricochet refers to the phenomenon when a projectile (like a bullet or a ball) bounces off a surface after striking it at an angle. The angle of incidence is equal to the angle of reflection. 2. **Movies and TV**: "Ricochet" is the title of various films and television episodes.
Rifleman's Rule, often cited in the context of marksmanship and shooting accuracy, asserts that a shooter should aim to achieve a "grouping" of shots—that is, the shots fired should land closely together on the target rather than being widely dispersed. This principle emphasizes the importance of consistency in shooting technique, including grip, stance, sight alignment, and trigger control.
