National Stock Numbers make supplying goods easier

National Stock Numbers make supplying goods easier

If you’ve ever purchased anything, you’ve seen a numbers on it that identify the item (a bar code). There is something similar that applies to items that are not used by the general public: National Stock Numbers. This relatively new concept is an important way to identify and obtain important items.

National Stock Numbers are one of the many things to come out of World War Two. With all the complications that were arising from trying to get an item that might be known by a dozen or more names, it was decided that an easier way to obtain these items was needed. That’s when these numbers were created. Legislation was introduced in the early 1950s to put this idea into action.

Blind Rivet – NSN 5320-01-597-4852

5320-01-597-4852 – Rivet Blind

Each National Stock Number is made up of several parts, much like other ID methods, all designed to give more information about the particular item. This includes the country or origin, manufacturer, and product specs/description. While the first two parts of the number can vary from manufacturer to manufacturer—or country to country—the last few numbers are the same for each product. For example, light bulbs will have the last part, or washers, etc. Other items that fall into this category are wire springs, communication equipment, heating components, and much more.

These convenient numbers are used by all Governments and are usually assigned upon the invention of a new part, weapon, or other item that will be used by Federal agencies or Military Services. They are also used to identify items that need to be disposed of in specific ways to ensure the safety of the environment and human health.

These numbers have made certain agencies run in a more efficient manner, while also providing transparency and safety of information. It also flags duplicate items to avoid waste.

F-16 Fighting Falcon

f16

The F-16 Fighting Falcon is a single-engine multirole fighter aircraft and it was originally created for the United States Air Force. Initially it was designed as an air superiority day fighter and it has now evolved into a highly successfully all-weather multi purpose aircraft. Production for the Falcon was approved in 1976 and over 4,500 aircrafts were built since then. Originally produced by General Dynamics, the manufacturing rights were given to Lockheed Martin when General Dynamics sold their business. Although they are no longer being purchased by the United States Air Force, improved versions of the Falcon are still being built for export customers.

The Fighting Falcon has several key features that lead to its exceptional service. Some of these features include a side-mounted control stick to allow for better maneuvering, a frameless bubble canopy for better visibility, and the first recorded use of a relaxed static stability flight, which is used to make it a nimble aircraft. Inside of the F-16, there is a M61 Vulcan cannon and eleven locations for mounting weapons and other missing equipment. Along with active duty in the USAF and the Air National Guard, the Fighting Falcon has also been known to serve in the air forces of 25 other countries.

Epoxy Adhesives

epoxy-adhesive Epoxy is a common name for a strong type of adhesive used for sticking things together and covering surfaces, usually two resins that need to be mixed together before use. Epoxy adhesives are the better choice when performing in heat and chemical resistance than other common adhesives. Epoxies have high melting and boiling points, which makes it useful as a solver as well. One may find popular two-part epoxy adhesives for the home, workplace or hobby activities in various stores ranging in a wide selection of properties. There are several properties to these epoxies including slow or fast curing time, waterproof or water-resistant, opaque or clear and flexible or rigid. Although many people believe that all epoxies are waterproof, many of them are not recommended to be underwater for the long-term. The shelf life for unmixed two-part epoxies is long and there are many reports of epoxies sitting idly for decades and still being used successfully. However, the ones more commonly seen in stores have a one to two year shelf life as published by the product specifications. Epoxy adhesives are an important part of the “structural adhesives” or “engineering adhesives” class. These are high performing adhesives that can be seen in the construction of aircrafts, cars, boats, skis and other applications that require high strength bonds. The adhesives can be developed to fit almost any application and can be used on wood, metal, glass and even some plastics. It is better for these types of epoxies to be cured with heat, as they will be more heat and chemical resistant than ones that are cured at room temperature. Two part epoxy coatings were made specifically for heavy duty service and dry quickly to provide a tough, protective coating with great hardness. The two part epoxies are usually used industrial and automotive applications because they are more heat resistant than other paints. One of the cons to the epoxy paints would be their deterioration due to UV exposure.

Active Military Helicopters

Helicopters (because of their ability to take off and land vertically, hover and fly forward and backward) are often used in congested or isolated areas where fixed-wing aircrafts and many other types of vertical takeoff and landing aircrafts cannot perform. Three very popular helicopters are the Boeing Ch-47 Chinook, Boeing AH-64 Apache, and the UH-60 Black Hawk. These copters are used mainly by the United States military but have been used in other countries.

The Boeing CH-47 Chinook is an American twin engine, tandem rotor heavy lift helicopter. Its primary roles include troop movement, artillery placements and battlefield resupply. It has also been used for medical evacuation, disaster relief, search and rescue, aircraft recovery, fire fighting and even heavy construction assistance. A lot of details go into the Chinook including the wide loading ramp at the rear. It also contains three external cargo hooks and can top its speed at 170 knots. The Chinook is the heaviest lifting western helicopter and it got its name from the Native American people. The helicopter was developed in the early 1960s. Although its first flight was on September 21, 1961, the Chinook’s formal introduction was in 1962.

The Chinook has been sold to sixteen different nations, the U.S. Army and the Royal Air Force being the two biggest users. The CH-47 was seen in the Vietnam War where the crewmembers found it hard to learn at first. Later on changes were made and the CH-47 was seen again in Iran in the 1970s when the Iranian armed forces began using American military aircraft. In the years to follow the Chinook also played a part in the Falklands, Afghanistan and Iraq Wars.

The Boeing AH-64 Apache is a four blade, twin turbo shaft attack helicopter with a tail wheel-type landing gear arrangement. The helicopter started production in April 1986. It has a tandem cockpit for a two-man crew and a nose mounted sensor suite used for target acquisition and night vision systems. Underneath the aircraft’s forward fuselage, one could find a 30 mm M230 chain gear. The United States Army, the primary operator of the Apache, designed the AH-64 to replace the AH-1 Cobra. The Apache became the primary attack helicopter of multiple nations including Greece, Japan, Israel, the Netherlands and Singapore. Other than the U.S. Army, other primary users are the Israel Air Force, Egyptian Air Force and the Royal Netherlands Air Force.

Lastly, the UH-60 Black Hawk is also a four bladed, twin engine, and medium lift helicopter. Originally it was submitted as a design for the United States Army’s Utility Tactical Transport Aircraft System (UTTAS) competition in 1972. The Black Hawk was selected as the winner of the program in 1976 after a fly off competition with the Boeing Vertol YUH-61. The UH-60 was first used as the army’s tactical transport helicopter. Later on it was added to the field of electronic warfare and special operations. The Black Hawk served in combat in Grenada, Panama, Iraq, the Balkans and several other locations.
