Circuit protectors are essential devices for proper aircraft functioning and are prompted to turn on in a variety of situations. First, circuit protectors are useful in the event of a short circuit which happens because of an electrical disruption between different voltage potentials. This can cause wire overheating and other equipment damage. Another situation aircraft circuit protectors are prepared for is overload, which occurs when devices in a circuit are pulling more current than the system is able to handle all at once. Chronic circuit overloading heats wires in a network and can cause parts to degrade.

If you are considering immersing yourself in the aviation realm, you must familiarize yourself with a few important terms, those of which are hydraulics and landing gear. These terms play an integral role in the overall functionality of aircraft. This blog will provide a general overview of each, allowing you to better understand their importance.

Countless assemblies require bearings or bushings of some kind to ensure that certain components maintain smooth rotation or resist vibration and shock imposed by outside stressors. In this blog, we will be providing a brief overview of each, allowing you to better understand their respective roles, varying types, and common materials. First, it is important to distinguish bearings and bushings from one another, as they are often conflated.

While fiber optic connectors and equipment are not quite a new form of technology, they have found increasing popularity and implementation in recent years through widespread adoption across many industries and applications. In order to install fiber optics within various settings and systems, adapters may be required in order to establish connections. As there are a variety of panels, systems, and components that fiber optic connectors may be paired with, there are multiple adapter types that one may choose from. To help you find the perfect solution for your applications, we will discuss the main types of fiber optic adapters that you may choose from.

Many aircraft are equipped with either a 14- or 28-volt direct current electrical system. Some systems are more advanced than others, but the basic aircraft electrical system comprises the following components: alternator/generator, battery, master/battery switch, alternator/generator switch, bus bar, fuses, & circuit breakers, voltage regulator, ammeter/load meter, and the associated electrical wiring. In this blog, we will discuss the main parts of aircraft electrical systems.

The aircraft hydraulic system is an extremely important element of numerous aircraft, allowing for high amounts of energy to be transferred for the actuation of systems and flight surfaces. As a system that relies upon contained liquids under pressure, hydraulics may be used for opening cargo doors, deploying landing gear, actuating aircraft rudders and spoilers, operating windshield wipers, and much more. As hydraulic systems help both small and large tasks be carried out, their proper functionality is paramount. While a number of factors can affect the functionality of hydraulic systems, the most important are temperature and pressure.

Networks are critical for supporting business, fostering communication, providing entertainment, and beyond. A key component of every network is the network switch, which allows devices within the network to connect to transmit data and share resources. The network switch operates at the Data Link layer of the OSI model (layer 2). It receives packets being sent by devices connected to its physical ports and redistributes them through the ports that lead to the device to which the packet is intended to go. They are also able to work at the network layer, layer 3, where routing occurs. While switches are used in networks based on ethernet, Fibre Channel, ATM (Asynchronous Transfer Mode), and InfiniBand, the majority of switches use ethernet.

Whether they are electromechanical or solid state, relays, solenoids, and contactors are all examples of switches. However, they all have differences and unique characteristics that make them better suited to different applications. This blog will cover all three and discuss certain considerations to make when deciding which device is best for you.

When watching a propeller aircraft begin to operate as the engine is turned on, it can be astounding to witness just how fast propellers can spin. Due to the speed at which propellers are operated at for achieving sufficient thrust, it can be difficult to see which way they are revolving. Furthermore, one may wonder if there is a standard for direction, and whether all move the same way. While a grand number of propellers tend to spin in a clockwise direction, there are some outliers that present the opposite operation.

Flight control surfaces are common aircraft devices that allow for pilots to manipulate the flight dynamics of the vehicle. Coming in the form of aviation parts such as ailerons, elevators, rudders, spoilers, and flaps, flight control surfaces are paramount for the efficiency and optimization of piloting and flight. As aircraft often operate in environments where they may face strong winds, prop washer, or jet efflux hazards, various means of protection are implemented in order to ensure the safety of such components.
