LSAT Caseless Ammunition
LSAT caseless ammunition is caseless ammunition produced as part of the U.S. Army’s Lightweight Small Arms Technologies (LSAT) program. Although less advanced in development than the other ammunition component of the program, the caseless round has already produced significant results. Having replicated Dynamit Nobel's ACR ammunition, the HITP (High Ignition Temperature Propellant, which is hexogen/octogen-based to decrease heat sensitivity) ammunition was modified to a 5.56 mm round. Tests proved the ammunition's usability, and development of the weapon was advanced using knowledge gained from the cased version. History The Alliant Techsystems ammunition production team cut production time and costs by reducing the number of steps used to complete processing from fourteen to two. The second spiral of caseless ammunition was rolled out in 2008, with the necessary facilities to produce the ammunition in bulk completed. It reduced the weight and volume of standard am ...

LSAT Caseless Ammo Packed
The Law School Admission Test (LSAT; ) is a standardized test administered by the Law School Admission Council (LSAC) for prospective law school candidates. It is designed to assess reading comprehension as well as logical and verbal reasoning proficiency. The test is an integral part of the law school admission process in the United States, Canada ( common law programs only), the University of Melbourne, Australia, and a growing number of other countries. The test had existed in some form since 1948, when it was created to give law schools a standardized way to assess applicants in addition to their GPA. The current form of the exam has been used since 1991. The exam has five total sections that include three scored multiple choice sections, an unscored experimental section, and an unscored writing section. Raw scores are converted to a scaled score with a high of 180, a low of 120, and a median score around 150. When an applicant applies to a law school all scores fr ...

Lightweight Small Arms Technologies
The Lightweight Small Arms Technologies (LSAT) program is funded by the U.S. Joint Service Small Arms Program, with the goal of significantly reducing the weight of small arms and their ammunition. Following a series of military programs to investigate advances in small arms ( SPIW, Future Rifle, ACR, OICW), the LSAT program is the US military's latest project to replace existing US small arms. Tactical concepts and the research from the previous small arms programs indicates that lightening small arms is the first significant step towards increasing soldiers' lethality and survivability. Initiated in 2004 (then called the Lightweight Machine Gun and Ammunition program), development is now led by Textron. Development began with two types of weight reducing ammunition, and a light machine gun to serve as a testbed and technology demonstrator. Minimization of program risk is shown by the development of the lower performing but less risky polymer-cased ammunition alongside cas ...

Dynamit Nobel
Dynamit Nobel AG is a German chemical and weapons company whose headquarters is in Troisdorf, Germany. It was founded in 1865 by Alfred Nobel. Creation After the death of his younger brother Emil in an 1864 nitroglycerin explosion at the family's armaments factory in Heleneborg, Stockholm, Nobel founded Nitroglycerin AB in Vinterviken, Stockholm. A year later, having found some German business partners, he launched the Alfred Nobel & Company in Germany, building an isolated factory in the Krümmel hills of Geesthacht near Hamburg. This business exported a liquid combination of nitroglycerin and gunpowder known as "Blasting Oil", but it was extremely unstable and difficult to transport, as shown in numerous catastrophes. The buildings of the Krümmel factory itself were destroyed in 1866 and again in 1870. In April 1866, the company shipped three unmarked crates of nitroglycerin to California for the Central Pacific Railroad, who wished to experiment with its blasting capability ...

Advanced Combat Rifle
The Advanced Combat Rifle (ACR) was a United States Army program, started in 1986, to find a replacement for the M16 assault rifle. Under the stress of battle the average soldier with an M16 may shoot a target at 45 meters, but hit probability is reduced to one out of ten shots on target by 220 meters. Because of this, the ACR program was initiated in the late 1980s to create a weapon that could double the hit probability. The ACR program was preceded by older programs such as the Special Purpose Individual Weapon. The program ended in 1990 after an expenditure of approximately US$300 million. Phase I and II Phase I of the program started in February 1986 when development contracts were placed with six companies: AAI Corporation, Ares Incorporated, Colt's Manufacturing Company, Heckler & Koch (H&K), McDonnell Douglas Helicopter Systems (MDHS), and Steyr Mannlicher. Two weapons were cut from the list before Phase II started. The companies started an appeals process and were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hexogen
RDX (abbreviation of "Research Department eXplosive") or hexogen, among other names, is an organic compound with the formula (O2N2CH2)3. It is a white solid without smell or taste, widely used as an explosive. Chemically, it is classified as a nitroamine alongside HMX, which is a more energetic explosive than TNT. It was used widely in World War II and remains common in military applications. RDX is often used in mixtures with other explosives and plasticizers or phlegmatizers (desensitizers); it is the explosive agent in C-4 plastic explosive. It is stable in storage and is considered one of the most energetic and brisant of the military high explosives, with a relative effectiveness factor of 1.60. Name RDX is also known, but less commonly, as cyclonite, hexogen (particularly in Russian, French, German and German-influenced languages), T4, and, chemically, as cyclotrimethylenetrinitramine. In the 1930s, the Royal Arsenal, Woolwich, started investigating cyclonite to use aga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Octogen
HMX, also called octogen, is a powerful and relatively insensitive nitroamine high explosive, chemically related to RDX. Like RDX, the compound's name is the subject of much speculation, having been variously listed as High Melting Explosive, Her Majesty's Explosive, High-velocity Military Explosive, or High-Molecular-weight RDX. The molecular structure of HMX consists of an eight-membered ring of alternating carbon and nitrogen atoms, with a nitro group attached to each nitrogen atom. Because of its high molecular weight, it is one of the most potent chemical explosives manufactured, although a number of newer ones, including HNIW and ONC, are more powerful. Production HMX is more complicated to manufacture than most explosives, and this confines it to specialist applications. It may be produced by nitration of hexamine in the presence of acetic anhydride, paraformaldehyde and ammonium nitrate. RDX produced using the Bachmann Process usually contains 8–10% HMX.

National Defense Industrial Association
The National Defense Industrial Association (NDIA) is a trade association for the United States government and defense industrial base. It is an 501(c)3 educational organization. Its headquarters are in Arlington, Virginia. NDIA was established in 1919 as a result of the inability of the defense industry to scale up the war effort during World War I. Founding In 1917, Brigadier General Benedict Crowell was called to active duty and served on the General Munitions Board. As a board member, he established a relationship with the steel industry and was almost immediately appointed Assistant Secretary of War and Director of Munitions. As Director of Munitions, Crowell was a significant catalyst in improving the country's capability to produce arms and ammunition. However, he recognized the nation's need for an association that fostered cooperation between civilian industry and government in support of industrial preparedness. He founded the Army Ordnance Association (AOA) in 1919 an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ablation
Ablation ( la, ablatio – removal) is removal or destruction of something from an object by vaporization, chipping, erosion, erosive processes or by other means. Examples of ablative materials are described below, and include spacecraft material for ascent and atmospheric reentry, ice and snow in glaciology, biological tissues in medicine and passive fire protection materials. Artificial intelligence In artificial intelligence (AI), especially machine learning, Ablation (artificial intelligence), ablation is the removal of a component of an AI system.

Caseless Ammunition
Caseless ammunition (CL), or rather caseless cartridge, is a configuration of weapon-cartridge that eliminates the cartridge case that typically holds the primer, propellant and projectile together as a unit. Instead, the propellant and primer are fitted to the projectile in another way so that a cartridge case is not needed, for example inside or outside the projectile depending on configuration. Caseless ammunition is an attempt to reduce the weight and cost of ammunition by dispensing with the case, which is typically precision made of brass or steel, as well as to simplify the operation of repeating guns by eliminating the need to extract and eject the empty case after firing. Its acceptance has been hampered by problems with production expenses, heat sensitivity, sealing, and fragility. Its use to date has been mainly limited to prototypes and low-powered guns, with some exceptions. Internal propellant caseless ammunition Description Older caseless ammunition typically ...
