Resistors are common electrical components found in circuitry, serving to implement electrical resistance. Resistors can play multiple roles within a circuit, commonly acting to reduce current flow, divide voltages, manage signal levels, bias active elements, terminate transmission lines, and much more. As a longstanding technology, a number of variations have come about to accommodate particular application requirements or needs. Wirewound, foil, and semiconductor resistors are three common types, each of which have their own unique construction and capabilities that benefit varying needs. In this blog, we will discuss each type, allowing you to best understand their design and applications.

Flight control surfaces permit a pilot to manage the attitude of a fixed-wing aircraft, coming in the form of aerodynamic devices that are spread across the vehicle. Aircraft elevators in particular are flight control surfaces that may be found near the rear end of the aircraft, adjusted by the pilot in order to govern the aircraft’s pitch, angle of attack, and lift. As a device that is commonly relied on during flight operations, pilots should always have a good understanding of its functionality and control so that they may best manage an aircraft safely and efficiently.

There are few things more frustrating than dealing with a tangled mess of cables. Not only are they difficult to untangle, but tangled cables can easily get unplugged in data centers, homes, offices, and so on. In this blog, we will look at five cable management tips to help you avoid such frustrations.

Unsurprisingly, the fuel tank is a critical part of every aircraft. To accommodate the wide range of aircraft types, there are many different types of aircraft fuel tanks. The three most common are rigid removable fuel tanks, bladder fuel tanks, and integral fuel tanks. In this blog, we will discuss each of these three types and their unique characteristics.

Engine valves are mechanical components used in internal combustion engines to control the flow of fluid and gas to or from the combustion chambers and cylinders during engine operation. They perform similarly to many other types of valves, blocking or allowing flow, but differ in that they are purely a mechanical device that works in conjunction with other engine components to open and close in the correct order with the correct timing. Engine valves are found in many types of combustion engines, whether they run off gasoline, diesel, kerosene, natural gas, or propane. In this blog, we will discuss the three main types of engine valves in detail.

When aircraft travel at the high altitudes that are standard for flight operations, the lack of oxygen pressure present in the atmosphere can create deadly environments for unprotected humans. As such, the negative effects of low atmospheric pressure are combated through manipulating air. Whether through increasing air pressure for more optimal breathing or by increasing the presence of oxygen within air mixtures, safe and comfortable environments may be achieved for the benefit of all operators and passengers.

When conducting military operations with aircraft, there are some times in which a particular unit needs to extend its natural range and cover large distances for travel. As fuel tanks are finite in their storage, most aircraft will eventually reach a point in which they need to land and refuel. For some military aircraft, however, advanced technology has allowed for refueling to be conducted mid-flight, permitting an aircraft to continue operations without the need for a landing. While seemingly simple at face value, mid-air refueling requires high amounts of pilot skill and specialty equipment to carry out the procedure.

Within the realm of material handling and construction, rigging refers to the process of setting up materials for lifting and transportation. Through the use of rigging equipment and lifting, the movement of heavy materials can be made quick and efficient. As such, enacting safe and proper rigging for a material handling operation is crucial. To best enact safe practices with rigging equipment, gaining an understanding of what common hardware pieces are and their functionalities should always be the first step for operators. In this blog, we will provide an overview of some of the primary rigging hardware pieces used in material handling, allowing you to improve your operations.

With countless aircraft operating throughout the night across the globe, external lighting on aircraft is important as to provide safety to pilots and others during flight. On almost all aircraft, various types of external lighting may be implemented in order to fulfill various purposes such making the aircraft more visible to others, assisting the pilot with more visibility during critical flight phases, or to provide light for others uses. In this blog, we will provide an overview of the various types of external aircraft lighting, allowing you to better understand their use and importance.

Hydraulic systems are used in a broad range of markets like aerospace, defense, marine, agricultural, plant, automotive, and more. For example, in aircraft, hydraulic systems are used to operate landing gear, flaps, flight control surfaces, and brakes, just to name a few. They generate power by utilizing pressurized liquid through a group of cylinders, hoses, and valves. The complexity of a hydraulic system ranges from those in small aircraft, which are used for manual operation of brakes, to sizeable transport aircraft with large, sophisticated systems. Although the vast majority of a hydraulic system is composed of cylinders and hydraulic hoses, there are many lesser-known accessories which are just as critical to the proper operation of the system. These accessories are pressure switches, hydraulic seals, pressure filters, flow indicators, and plugs. This blog will explain each one and its greater role in the hydraulic system as a whole.
