A semiconductor device is a device that is made from material which is neither a good conductor nor a good insulator. Its conductivity is generally between that of a typical insulator and most metals, due either to the addition of an impurity or because of temperature effects. Semiconductors are widely popular in a wide variety of applications due to their reliability, compactness, and low cost.
Avionics radios are extremely important for the safety of any aircraft and pilot during flight operations. Aircraft radios allow for navigation during flight and establish two way communication with flight controllers and personnel. While most aircraft are designed with a panel mount radio for navigation and communication already installed, it is highly recommended to also have a handheld radio on hand for emergency purposes. Some aircraft also may not have panel mount radios installed, thus avionics handheld radios can be a cost effective entry to provide the radio functionalities needed for safe flying. Lastly, students can also benefit from handheld radios to train and familiarize themselves with radio communication. In this article, we will discuss avionics handheld radios, as well as important information on their types and components to help you familiarize yourself with them.
When inevitable issues arise in your electronic system, the age old answer is always “did you try turning it on and off again?” While this may be a suitable answer for a personal computer or mobile phone, this is not always acceptable for servers and networks where downtime warrants major issues and setbacks for a company or service. When these systems eventually need parts replacement, additions, or removals, they need to be serviced in a way that does not require powering down or interrupting the system. Luckily, the solution to this problem comes in the form of hot swap connectors and hot swapping.
When thinking about an aircraft engine, we are often familiar with some of the basic components. We know of the combustion chamber, cylinders, and other various engine parts. Not often though are people aware of what houses all these parts together. The aircraft crankcase is the “house” or “body” of the engine, holding all the various engine parts that work together to provide flight. Beyond housing parts, the crankcase also contains the engine oil lubrication system containing lubrication assembly parts that keeps components clean and cool, and attaches the powerplant to the aircraft.
Having a robust fire protection and prevention system in place is important for any building, commercial or residential. Fires can do more harm than just to humans and animals; they can destroy personal belongings, damage or destroy buildings, and cost a lot in repairs. That is why automatic fire fighting methods in buildings are designed to put out fires before they have time to cause much damage, often before or immediately after combustion. In this blog, we will be discussing how fire systems and fire sprinklers work together to protect buildings, livelihoods, and all inbetween.
To successfully power a turbine engine and produce flight, an aircraft needs a combustion engine to mix air and fuel, as well as ignite it. From their inception, combustion chambers have been an evolving technology. Through the history of aviation, three main types of combustion chambers have been prominently used, including the can, cannular, and annular combustors. In this blog, we will give a short overview of how these combustors work to produce energy for an aircraft.
If you’re in the aviation industry, you may have heard the term “shroud.” The term alone refers to an object that obscures something from view. In the aeronautical industry, there are different types of shrouds that can be utilized for different functions, such as exhaust shrouds for carbon heat and cabin heat in light planes. But in this piece, we’ll discuss briefly the definition and functions of the most commonly used shroud in aircraft.
Whether an aircraft’s cockpit utilizes a steam gauge or is a modern glass panel, the functionality and principles of the airspeed indicator mostly remains the same. Airspeed indicators are critical to the operation of a flight, enabling pilots to maintain safe operating speeds through speed measurements. In this article, we will discuss how airspeed indicators function and how readings are made.
For aircraft construction, bearings and seals are almost always utilized in rotating or rolling components. Bearings are utilized to constrain movement to specific motions and axes, and work to reduce the friction between moving components. Bearings can also work to disperse stress of the component loads. Seals on the other hand, help prevent contamination, such as dirt, from entering the bearing gaps, as well as encases bearing lubricant inside. So what are some examples of the types of bearings and seals that can be used?
Turbojet engines are truly fascinating pieces of machinery. An array of tiny, individual pieces combine to form something greater than the sum of its parts. While it would be irresponsible to imply that they are simple machines, when you break down a turbojet engine, they are surprisingly easy to understand. Turbojet engines consist of just five primary components. These are the intake, compressor, combustion chamber, turbine, and exhaust.
