For a computer to provide the various capabilities and uses that we rely on in our day-to-day lives, they require different forms of memory. Regarding electronic applications, memory refers to any device that may store data and information for a computer system to use. Computer memory also ranges in its form and application, as memory and data storage may be volatile or non-volatile in its operation and use. Due to the immense importance that computers now serve in modern societies, having a general understanding of the common types of computer memory devices that are used can be useful for anyone operating or owning such systems.
A valve is a mechanical or electromechanical device used to control the movement of liquids, gases, powders, and more, through pipes or tubes or from tanks or other containers. In most applications, valves rely on a plate, ball, diaphragm, or some other type or mechanical barrier that can be inserted to or removed from the flow stream of the material flowing through. Some valves are strictly of the on/off variety, while others allow the user to control the flow rate of the media traveling through it. The type of material a valve is made from also plays an important role in distinguishing valves and ensuring the compatibility of the wetted parts of the valve with the fluid passing through it. Furthermore, sizing is determined by the pipe or tubing diameter, flow rate, and in pipeline valves being installed as replacements, the width between flanges.
In the aircraft construction and repair industry, fasteners are critical tools needed to assemble detailed parts and combine them with other parts to form assemblies. These assemblies are in turn combined to form installations which eventually make up a complete aircraft. Fasteners are found throughout all parts of an aircraft. For instance, there are approximately six million parts used to fabricate a Boeing 747, over half of which are fasteners. Fasteners are used to connect parts in primary and secondary structural areas, pressurized and unpressurized applications, as well as to transfer loads from one part to another in production and repair applications. This blog will provide a thorough look at aircraft fasteners and their uses, types, codes, designs, and more.
When owning or operating a private aircraft, it is crucial that one has easy access to storage, fueling, inspection, maintenance, and other services to ensure that their aircraft are well taken care of.

Fixed base operators are organizations that provide a variety of aeronautical services to customers across the globe, and they are widely used by private jet owners, passengers, and operators.
A wing is a type of fin used to produce lift while moving through air or another type of fluid. Wings feature streamlined cross-sections that are subject to aerodynamic forces and act as airfoils. The aerodynamic efficiency of a wing is expressed through its lift-to-drag-ratio. The lift generated by a wing at a given angle of attack can be one to two orders of magnitude larger than the total drag on the wing. If a wing produces a high lift-to-drag ratio, a significantly smaller amount of thrust is required to propel the wings through the air at sufficient lift.
A propulsion system is an apparatus that converts mechanical power into a propulsive force, pushing or pulling an object to drive it forward. Within the realm of aerospace, the aircraft propulsion system often consists of an aircraft engine to produce thrust, allowing it to achieve sustained, heavier-than-air flight. Depending on the type of aircraft, various propulsion systems may be implemented to achieve flight, and each utilizes varying components and properties for their operation. In this blog, we will discuss two of the most common propulsion system types, as well as some of their various subtypes.
Within the realm of aviation, aircraft tugs and safety equipment are extremely beneficial for flight operations, allowing for aircraft of all sizes to be safely moved around a runway. While many aircraft have the ability of moving themselves backwards through the use of reverse thrust, this poses a number of logistical problems and dangers. With the power produced from thrust, gateways could be damaged, surrounding personnel harmed, and engines may be damaged from debris that is sucked in. Because of this, tugs are widely used for aircraft ranging from light personal planes to jumbo airliners.
A filter element is the central component of any filter, where the actual process of filtration takes place. Generally speaking, filter elements are divided into two classes: surface and depth. Surface filters are made from closely woven fabric or treated paper and feature uniform pore sizes. Fluid flows through the pores of the filter while debris and contaminants are stopped at the filter surface. Surface filters are designed to prevent the passage of a high percentage of solids of a given size.
Ruthenium is a chemical element from the periodic cable, existing in the form of a rare transition metal that belongs to the platinum group. Ruthenium is considered chemically inert, meaning that it does not undergo any reactions when it comes into contact with most chemicals, whether in nature or during the manufacturing process. While tarnish may not result from ruthenium being in a room temperature environment, it may be explosive from oxidation, and may be attacked by hydroxides and halogenics. Ruthenium was discovered in Kazan, Russia in 1844, and it is most often found as a part of platinum ores. Ruthenium may present use across a variety of applications ranging from benefitting chemical process catalysts to combining with platinum and palladium to manufacture electrical contacts. They are also very useful for a number of aerospace and aircraft manufacturing, due in part to their high melting point and robustness among other properties.
A CAGE code, or Commercial and Government Entity code, is a unique 5 character alphanumeric code that can be given to a business as a unique identifier. CAGE codes are important as they are the way that an entity is able to do business with the United States government and identify themselves. In this blog, we will discuss the various facets of CAGE codes and why they are important for an entity to have.
Aircraft cabin air systems are key in the reduction of dust, fibers, bacteria, and other microorganisms that would otherwise be present in an aircraft fuselage. They also play an important role in the simple act of breathing itself. At 35,000 feet, a fairly average cruising altitude, air pressure is low enough that even breathing pure oxygen would not provide your body with a sufficient amount of air. For this reason, all airline cabins are pressurized and require an intricate air system to pump in breathable air for passengers and all others aboard.
In our modern society, electricity has become nothing less than a necessity for both the functionality of our businesses and our homes.

These mil-spec parts are components that have been manufactured to meet comprehensive requirements that have been set out by the Department of Defense in an effort to create standardization and interchangeability of parts. Mil-spec components are often denoted by a prefix (i.e. AN, MS, NAS, or NASM) before a part number.
All aircraft engines require regular maintenance to ensure safe and healthy performance, and proper maintenance requires having the proper tools. If you have a turboprop engine like a Pratt and Whitney PT6A, this list of essential tools will help you keep it running healthy for its full lifespan.
Powered aircraft obviously require fuel to achieve flight, and these systems must be both safe and efficient in how they transfer fuel from the tanks to the engines. The design and complexity of these systems, however, largely depends on the aircraft itself, with the size and layout being the most critical factors. A high-wing aircraft will use a different fuel system from a low-wing aircraft, for instance, and engines with carburetors will have different requirements compared to those with fuel injection.
Computer memory can be an overwhelming topic especially when faced with the seemingly never-ending list of acronyms such as RAM, ROM, DRAM, SRAM, DDR, SDRAM etc. The easiest way to decide which computer memory is right for you, is to think about your own basic requirements. For most, the basic considerations are the standard of memory, the capabilities of their computer’s motherboard, and the speed of memory they require.
No matter their design or model, all aircraft require airplane fuel to achieve flight. This makes fuel an extreme necessity, but the price of fuel is not a fixed point. Prices increased twenty two percent over the course of 2018 and accounted for 20% of air companies overall operating cost. Airlines can do their best to avoid these hefty prices by becoming more fuel efficient. However, there needs to be a balance between fuel economy and consistent on-time operations.
One way to maximize the lifespan of hydraulic components is the ensure the internal sliding parts are sufficiently lubricated to minimize friction and corrosion. Due to the cost of repair or maintenance, some parts are considered more vital to the overall functioning more so than others; pumps and valves are critical components. Hydraulic fluids serve multiple purposes. The major function is to provide energy transmission throughout the system which enables motion to be accomplished; however, hydraulic fluids are also responsible for lubrication, heat transfer, and contamination control. Which type of lubricant you decide to use is significant as well.
Propellants are used in the production of pressurized gas or energy. The gas or energy is then used to propel a vehicle, projectile, or other objects. The most common propellant is fuel, whether it be gasoline, jet fuel, rocket fuel, etc. When propellants are decomposed or burned, they release the propellant gas. Some propellants are liquids that can be vaporized. Propellant gas, or exhaust, propels object forward by using a chemical reaction or combustion which increases its pressure.
The colors and symbols used on an aircraft are instantly recognizable. At this moment, even mentioning the name of American Airlines, Mango Airlines, or Southwest airlines brings an assortment of imagery and colors to my mind.
