Collaborative Research into Small Arms Technology (CRISAT) typically refers to initiatives or programs that focus on the study and development of small arms and their associated technologies through collaborative efforts among various stakeholders. These stakeholders can include governments, academic institutions, private industry, and non-governmental organizations (NGOs). The objectives of such collaborative research might include: 1. **Innovating Safer Technologies**: Developing new materials or designs that enhance safety in the use of small arms and reduce accidental discharges.
Centerfire ammunition is a type of cartridge that has its primer located at the center of the cartridge case head. This design contrasts with rimfire ammunition, where the primer is located on the rim of the cartridge. Centerfire cartridges are generally considered to be more robust and reliable than rimfire cartridges, as they can handle higher pressures and are suitable for a wider range of firearms, from handguns to rifles.
Caseless ammunition is a type of firearm ammunition that does not have a traditional cartridge case. In standard ammunition, the cartridge case serves multiple functions: it holds the primer and propellant, provides structural integrity, and ejects from the firearm after firing. In caseless ammunition, these functions are achieved without a separate case. Instead, caseless ammunition typically consists of a propellant that is chemically designed to contain the projectile and primer within the cartridge itself.
A cartridge box is a container used to hold cartridges, which are devices that contain a projectile (such as a bullet), propellant, and primer. Historically, cartridge boxes were used extensively during the 19th and early 20th centuries, particularly in military contexts, to store and transport ammunition for rifles, pistols, and other firearms. Cartridge boxes could be made from various materials, including wood, metal, leather, or canvas.
A cartridge, in the context of firearms, is a complete unit of ammunition that consists of several components assembled together. A typical cartridge includes: 1. **Bullet**: The projectile that is fired from the firearm. It is usually made of lead or a lead alloy, sometimes with a metal jacket. 2. **Propellant**: Usually gunpowder, this substance ignites and creates gas when burned, propelling the bullet out of the cartridge and down the barrel of the firearm.
Cannelure refers to a groove or groove-like feature, often seen on the surface of bullets or casings in firearms and ammunition. These grooves are typically applied to the bullet to serve specific purposes, such as: 1. **Crimping**: The cannelure allows for a crimping process to hold the bullet securely in place within the cartridge case. This helps prevent movement of the bullet under recoil or during handling and ensures consistent performance.
"Caliber" can refer to several different concepts depending on the context. Here are a few common interpretations: 1. **Measurement**: In a general sense, "caliber" refers to the diameter of a cylindrical object, often used in the context of firearms to indicate the diameter of the gun's barrel or the projectile (bullet) it fires. For example, a .38 caliber revolver fires a bullet that is .38 inches in diameter.
Buck and ball is a historical form of ammunition used primarily in smoothbore firearms, particularly during the 18th and early 19th centuries. It consists of a lead ball (usually .69 caliber) and several smaller lead shot (often referred to as "buckshot") packed together in a single cartridge. When fired, the larger ball would travel towards the target with considerable force, while the smaller shot would spread out, increasing the likelihood of hitting multiple targets at close range.
A bourrelet is a specific feature found on the projectile of large-caliber artillery, such as shells and missiles. It refers to a raised band or ring that is located around the circumference of the projectile, typically near its base. The primary functions of a bourrelet include providing a guiding surface that helps ensure better alignment within the barrel during the firing process, minimizing gas leakage, and contributing to the overall stability of the projectile as it travels through the air.
"Bolt thrust" typically refers to the force exerted by a bolt when it is subjected to a load, especially in mechanical and structural engineering contexts. When a bolt is used to fasten two or more components together, it experiences tension or shear forces depending on the application and loading conditions. The term "thrust" often relates to the axial force acting along the length of the bolt.
A "blank" cartridge is a type of firearm ammunition that contains gunpowder but lacks a projectile (bullet). Instead of a bullet, it typically has a wad or a simple plug that seals the case. Blank cartridges are designed to produce a loud noise and a muzzle flash similar to that of regular ammunition when fired, but they do not launch a projectile, making them safer for certain uses.
A black powder cartridge is a type of ammunition that uses black powder as its propellant. Black powder, also known as gunpowder, is a mixture of saltpeter (potassium nitrate), charcoal, and sulfur. While black powder was historically the first form of smokeless propellant used in firearms, it has largely been replaced by smokeless powder in modern ammunition due to its higher energy density and efficiency.
"Black Talon" can refer to different things depending on the context. Here are a few possible meanings: 1. **Firearms and Ammunition**: Black Talon is most commonly known as a brand of high-performance ammunition produced by Winchester. It gained notoriety in the 1990s for its design, which featured a black-coated bullet and a special hollow point intended to expand upon impact.
The term "belted magnum" refers to a type of cartridge design in the field of firearms and ammunition. The term "belted" indicates that the cartridge has a pronounced belt around its case, which serves several purposes: 1. **Headspacing**: The belt helps to provide a consistent and reliable point for the cartridge to headspace (the position in relation to the chamber) when it is chambered in a firearm.
The Beehive round is a type of anti-personnel ammunition used primarily in artillery systems. It consists of a shell that contains numerous small steel balls or projectiles, which are released upon detonation. The design is intended to create a large area of effect to target enemy personnel rather than vehicles or other armored targets. When fired, the Beehive round disperses its projectiles over a wide area, making it effective for suppressing infantry formations or for use in close combat situations.
Bandolier can refer to a couple of different things, depending on the context: 1. **Historical Context**: In a historical and military context, a bandolier is a type of shoulder belt or strap that is used to hold ammunition, usually consisting of several loops or pockets. Bandoliers were commonly used by soldiers to carry cartridge cases or bullets, allowing for quick access to ammunition in combat situations. They can be made from various materials, including leather and cloth.
Armour-piercing fin-stabilized discarding sabot (APFSDS) is a type of ammunition used primarily in modern tank and artillery systems. This projectile is designed to penetrate armor, especially in modern tanks or fortified positions, utilizing both kinetic energy and specialized design characteristics. Here are the key components of APFSDS: 1. **Armour-Piercing**: The projectile is engineered to defeat armored targets.
Armour-piercing discarding sabot (APDS) is a type of ammunition designed to penetrate armored targets, such as tanks and fortified positions. It consists of a projectile (the "dart" or "penetrator") made from high-density materials, typically tungsten or depleted uranium, which is encased in a lightweight sabot. The sabot is a carrier that allows the projectile to be fired from a smoothbore or rifled gun.
An ammunition box is a container designed specifically for the storage and transport of ammunition. It is typically made from materials such as metal, plastic, or wood and is designed to protect the ammunition from physical damage, moisture, and other environmental factors that could affect its performance. Ammunition boxes come in various sizes and styles, tailored to hold different types of ammunition, such as small arms cartridges, shotgun shells, or larger calibers.
