Whether an aircraft features a gas turbine or reciprocating engine, most aircraft engines require some sort of assistance in initiating their starting process. Known as starters, such devices are electromechanical mechanisms that produce the mechanical energy required to rotate an engine before it becomes self-sustainable. As different engines require varying amounts of force and rotation to begin their operations, there are numerous engine starting systems that may benefit particular aircraft types. In this blog, we will provide a brief overview of the common aircraft engine starting systems so that you may find what is best for your particular needs.

During standard flight operations, pilots regularly use their radio equipment in order to establish and maintain communication with Air Traffic Control personnel and others for the means of safety. As radio interference can affect the quality and capability of communication, it is essential that engineers enact proper measures to suppress electromagnetic fields and electrostatic interference. While some interference may manifest as audible noises from communication systems, large static electricity discharges can present a hazard to sensitive components if they are unprotected. Across most aircraft, the most common methods of reducing radio interference include shielding, isolation, bonding, and static discharge wicks.

In order to produce a safe, efficient and productive environment suited for utilizing high-powered electrical devices, the act of grounding is a necessary and crucial one. In the case that equipment or an electronic device breaks down or malfunctions enough to start spewing a harmful amount of current, the act of grounding allows the circuit to safely dissipate the excess charge. Grounding prevents harm to surrounding devices, but along with this, grounding can prevent harm such as shock or electrocution from coming to people. However the process of grounding is made much more complicated with aircraft as they can be cruising at an altitude of around 35,000 feet or higher. This begs the question, how is any aviation expert / engineer able to produce grounded electrical circuits in aircraft that are designed to fly above ground?

The resistance temperature detector (RTD) and thermocouple are two examples of devices used to monitor temperatures. Because their function is so similar, the two are often mistaken. Despite this, the RTD and thermocouple have distinct differences in their principle operation. An RTD uses a single piece of metal whose changes in resistance represent the changes in temperatures. On the other hand, a thermocouple uses two metallic wires which generate a difference in voltages at the junction which corresponds to the change in temperatures. This blog will explain both RTDs and thermocouples in depth, as well as their many differences.

Electrical connectors are used as a type of electro-mechanical trigger that serves to combine electrical circuits. This mesh of electrical circuits acts as a connector and interface and it is achieved by the use of mechanical assembly. These connectors are made up of jacks, those of which have a male end and plugs with a female end. The electrical connectors are a crucial component because they can be utilized alongside an adapter for a short term solution as well as a permanent solution. For more information on electrical connectors, read on below.

Electrical connectors are a type of hardware that joins with a device to complete an electrical circuit and transmit electricity to a piece of equipment. This connection can be either wire to wire or wire to terminal. The process of joining the wires to each other or a terminal is called crimping. Crimping occurs when one piece of metal is deformed and compressed tightly with another piece of metal. The process does not necessitate soldering, but does involve specific steps and equipment.

Regardless of whether you’re a novice in the aviation industry or well versed in the mechanics of the industry, it’s worth knowing about the APU, or auxiliary power unit, in an aircraft. Put simply, the APU acts as an extra source of power for the main engines on a business jet or airliner. Equipped with an additional electrical generator, the APU is designed to produce sufficient fuel for the aircraft’s galley electrics, cockpit avionics, onboard lighting and more. It is also manufactured to heat up and cool down the aircraft by way of drawing bleed air from its own compressor.

The production cost of an aircraft is staggering, thus, training an inexperienced pilot in one is counterintuitive. The cost of human lives is also something to consider; would-be pilots don’t have enough experience and have the potential to damage the aircraft or injure themselves. Therefore, a flight simulator is the perfect solution. Flight simulators recreate the experience of flying an aircraft by utilizing virtual reality software for the purpose of pilot training and technical development. The aircraft systems, flight controls, and air conditions are all replicated, allowing the pilot to experience different flight scenarios. Simulators can range from full-sized cockpits on hydraulic actuators with state-of-the-art technology to desktop computer-based games.

Light-emitting diodes (LEDs) are currently the most efficient light bulb on the market, often out-performing formerly popular compact fluorescent lamps (CFLs) and incandescent bulbs. The lights have the potential to create a more sustainable future for energy in the United States. It is estimated that if every American replaced one conventional light bulb with an LED, the energy savings would be equivalent to removing the greenhouse gas emissions of 800,000 cars. Let’s take a look at the history of LEDs, and how their technology has the capacity to change power consumption in the United States.

Have you ever wondered why the phrase “the nuts and bolts of it” exists? The reasoning might help in remembering the biggest difference between screws and bolts. A bolt is defined as a threaded fastener with a nut and a flat bottom. It requires a nut to secure it to a material. The bolt can only be loosened when torque is applied to the nut. A screw, for all intents and purposes, is a threaded fastener without those attributes— it is defined as a screw head with a circular helical ridge. Screws are fastened by applying torque to the head.

Gears are little confusing. There are so many different terms that can be used for the same thing, and there are so many slightly different things that the same general term can refer to. And “gearbox” is one of those terms. Despite the fact that they actually refer to slightly different gear arrangements, gearboxes are other interchangeably used with “gearhead” and “gear reducer”.

Fasteners are typically small hardware pieces such as washers, screws, studs fasteners and more. Fasteners are used in several different industries including aerospace. One of the oldest and most common fasteners on the market is the nail. The standard nail is made of a shank, or a metal rod, and is flat at the top with an end that is pointed. Nails are typically hammered into wood, drywall, etc. and are used to fasten materials together. The standard nail is made from steel, but other variations include aluminum, brass, bronze, iron, or copper. The United States alone has over 300 different types of nails manufactured, most of which are used in residential construction.
