Interconnecting the electrical systems in your aircraft is a crucial part of certification. Aircraft EWIS requirements are mandated by US Federal Aviation Regulations (FAR) Part 25 - Subpart H for all transport type planes. To best avoid the risk of part failure, designers must now consider component design limitations, functionality, and susceptibility. One such important element of electrical wiring interconnect systems is shielding, that of which is used to control the electromagnetic interference characteristics of subsystems and equipment. While shielding is a crucial part of many electrical assemblies, some aircraft wiring will require shielding, while other wires will not. This blog will shed light on the several considerations that will help you determine when you should shield aircraft wiring. To begin, let us understand why we need aircraft shielding for wiring in the first place.

As our homes are being filled with different video sources and other equipment like receivers and projectors, your remote control system can quickly become an inconvenience. While you may want to hide equipment away to minimize the electronic clutter in your home, covering up the infrared receivers built into your devices renders remote controls useless. The solution to this: IR (infrared) repeaters.

Hydraulic technology has become a mainstay in a wide range of industries, powering tools, vehicles, and power transmission systems. One such application, in particular, that has recently become popular is the hydraulic jack. These machines can be used to lift heavy loads with unmatched efficiency and minimal energy input. In this blog, we will discuss the design and numerous applications of hydraulic jacks across the several industries in which it is implemented.

Pilots need a vehicle that can withstand the rigors of flight and keep on working. Nuts are the fasteners that hold together different parts of an airplane. Nuts for aviation use come in many different sizes and styles, with the most common being hardened steel or corrosion-resistant metal types. They can also be made from various materials, including stainless steel (which has high durability), tempered titanium aluminum alloys, and more. The aviation industry is filled with many different types of nuts, those of which  can be divided into two categories: Non-self-locking nuts, called standard nuts, and self-locking nuts. In this blog, we will be discussing these two categories and the types of nuts that belong to them.

Non-Self-Locking Nuts

Pressure is an important aspect of combustion engine operations, allowing for the belts and pulleys of alternators, AC units, and other systems to be driven. While this pressure is crucial for the functionality of systems, it also needs to be safely released to prevent damage or various hazards. For most vehicles, this is done with the use of a vacuum pump. In diesel engines, vacuum pumps will also serve other roles such as powering the brake system and air conditioning unit, furthering their importance. Just like any mechanical part, vacuum pump components are subject to wear and tear over time, leading to the possibility of an eventual breakdown. In this blog, we will discuss some of the most common signs of a faulty or failing vacuum pump, ensuring that you always know when it is time to make a replacement.
