Nuts are common hardware components that are paired with fasteners such as bolts and screws to secure an assembly together. With general nut types, such components are installed to the backside of a component after the bolt or screw has been passed through a pre-drilled hole, the two fasteners then tightening to clamp parts together. In the case that parts to be assembled are too soft for accepting a threaded insert, or can only be accessed from one side, a specialty component known as a rivet nut may be used. Developed in the 1930s, rivet nuts, also known as rivnuts or blind rivet nuts, are internally threaded components that may be anchored to one side of an assembly.

Aircraft engines are often subject to major stresses during standard flight operations, taking on a large amount of strain due to the combustion process and the presence of immensely hot exhaust gases. Because of the wear and tear that such assemblies face over time, they regularly need to be inspected to ensure that any issues or damage is remedied before a failure can occur. At certain thresholds of operating hours, intensive inspections must be carried out where the engine is fully disassembled to thoroughly look over each and every component for its health. For the most inaccessible components, a device known as a borescope is commonly used. Featuring a small camera that may be inserted into assemblies for obtaining live images, having an understanding of the basic components that make them up and how they are used can be beneficial for any aerospace engineer.

Used in either air or water, propellers are affixed to many types of vehicles as a means of generating thrust between a fluid and a rotating propeller assembly. Sustaining momentum without putting strain on humans and capable of creating more power than that of a steam-power engine, ship propellers and their revolutionization through decades of research have increased the efficiency of ship performance and travel capabilities. Frequently built attached to a rudder that spins an joined propeller unit, modern marine propellers are often manufactured as rotatable screw propellers that come affixed with helical blades. As there are varying types of propellers for specific applications, we will discuss in detail how marine propellers operate and why their specific design directly correlates to their performance.

Electronic devices and appliances are extremely useful for much of our daily activities, providing us with the means of lighting spaces, operating machinery, communicating with others over distances, entertaining ourselves, and much more. While electrical components and equipment may be advanced and robust in design, they still require regular maintenance and ample protection to maintain their operability and efficiency over time. To help you best protect and maintain the electrical equipment of your space or facility, we will discuss common practices and maintenance procedure that you should be familiar with.

For aircraft to efficiently operate through a range of extreme temperatures, pressures, and humidity, they are held to high standards during their design, construction, and general maintenance. In order to achieve such readiness and reliability, aircraft engines in particular need to be well maintained and protected from heat and lubricant anomalies. To ensure that engine parts are well protected, advanced engine oils and lubricants may be used in order to cool components and mitigate friction. As engine oil is similarly held to high scrutiny for performance, many engine manufacturers will conduct oil analysis as part of engine development and testing.

The process of manufacturing a boat involves many steps including design, fabrication, assembly, testing, and so on. Design, in addition to being the first step, is among the most important. A pivotal aspect of the design process is deciding which material to use for the boat’s hull. In this blog we will discuss the four most commonly used materials for shipbuilding: steel, aluminum, fiber-reinforced plastic (FRP), and polyethylene.

When operating an aircraft, there are various flight characteristics that pilots must consistently monitor and be aware of for both flight efficiency and safety. One of these characteristics is the speed of the aircraft, and this value is used to ensure the aircraft is operating at safe velocities and is following set flight plans for fuel management and scheduling. To measure airspeed, pilots rely on an instrument known as an airspeed indicator (ASI). In this blog, we will discuss how aircraft airspeed indicator functions, as well as the various types of airspeed measurements that can be obtained with their readings.

As artificial intelligence and data science continue to improve, countless industries have revolutionized their operations through its implementation. The airline industry is no exception to this change as technology has enabled many operations to become more efficient and streamlined. From booking flights to managing maintenance schedules and crews, artificial intelligence provides airlines the capability to improve upon procedures that benefit both industry workers and consumers who rely on them for traveling across the world.

A personal electronic device, or PED, is a piece of lightweight, electrically-powered equipment. PEDs most commonly refer to consumer electronic devices such as laptop computers, tablets, e-readers, smartphones, MP3 players, drones, electronic toys, and any other device capable of communications, data processing, and/or computing. Like any electronic device, there is the possibility that the PED can fail and potentially catch on fire. When bringing a PED aboard an aircraft, it is important to know how to prevent these fires, and how to react to one should it occur.

Despite the many impressive advancements made in the field of alternative energies, the vast majority of private and commercial aircraft still run on fuel. The function of an aircraft engine is not much different than that of any other type of engine - they burn fuel within the engine's combustion chambers to create propulsion. However, the biggest difference in the function of these engines comes in the form of the type of fuel they burn. Instead of the fuel used by cars, trucks, and other automobiles, aircraft require a specific type of fuel for optimal performance and efficiency. This is known as kerosene fuel.
