Avionics are defined as the electronic systems found on aircraft, spacecraft, and satellites. In fact, it is these systems that make flight possible, allowing pilots to operate aircraft safely. The term “avionics” comes from combining “aviation” with “electronics,” and it is a term familiar to many in the aerospace world. In this blog, we will cover the seven systems that make up the basics of avionics.

If you own or operate an aircraft, it is important that the vehicle is well maintained to uphold performance, safety, and reliability of all parts and systems. It is often required to carry out various types of inspections on a regular basis, and regular maintenance can prevent the chance of needing to carry out costly and time-consuming repairs. As such, one should become familiar with the basic types of maintenance that must be carried out, alongside common tips to extend surface lives and deter wear and tear.

Since engines wear out as a result of high temperatures, vibration, friction, corrosion, and damage from the ingestion of foreign objects, this combination of stressors, coupled with the high speed of the rotating engine, causes mental fatigue over time. To ensure your engine remains reliable and durable, routine engine maintenance is paramount. In fact, maintenance, repair, and overhaul operations can increase the service life of an engine, eliminating the need for extensive and expensive repairs in the long run.

As aircraft are subjected to a wide-range of environmental extremes and unprecedented stressors, they may experience fatigue or structural failure over time. To be considered airworthy, aircraft undergo rigorous testing before being deemed safe and certified for flight. According to Boeing, equipment and structural failure accounts for about 20% of aircraft accidents, while mechanical failure is attributed for nearly 80%.

When certain devices conduct signal transmission for their standard operations, they may take advantage of frequency-domain multiplexing, that of which is a technique that serves to divide the total bandwidth into non-overlapping frequency bands for carrying separate signals. This is highly beneficial when one needs to send multiple independent signals over a single cable or optical fiber, and such multiplexing is made possible through passive RF filters known as diplexers. As a filter component featuring three ports, two frequency bands may share an antenna so that separate signals can be transmitted and received simultaneously. In this blog, we will discuss diplexers in more detail, allowing you to have a better understanding of how they are used.

Compressors, transmissions, drill presses, and other such apparatuses are all important assemblies for various applications and industries, and all of them share a reliance on an often overlooked component known as a quill shaft. Such components are quite small, coming in the form of thin, solid shafts that are designed to undertake the amount of torque that a larger shaft would. This is made possible through their ability to operate at higher stress levels, carrying torque similarly to a torsional spring as it twists along its length. Quill shafts have found implementation in various assemblies pertaining to diverse industries, and it can be useful to have a general understanding of their use.

In the realm of aviation, drag is an aerodynamic force that constantly acts against an aircraft as it traverses the sky. As a type of restrictive force, drag opposes the motion of an aircraft, causing it to lose airspeed. There are multiple types of drag that one may experience during a flight operation, and each differs in its source and characteristics. As a pilot will regularly face all types of drag during their career, it can be extremely beneficial to be aware of each type and their cause.

When implementing numerous electronic systems in a single location, whether for an office or entertainment center, the amount of cables needed for all devices can take up space and quickly necessitate management for proper organization. To best organize cables, three common cable management solutions are commonly used. These include heat shrink tubing, cold shrink tubing, and electrical tape. To help you find which type is best suited for your particular needs, we will discuss each.

A blind rivet, otherwise known as a POP rivet, is a specialized fastener that assists personnel in the assembly of components where there is no access to the rear side of the joint. Standard rivets feature a solid shank and hat, capable of being installed into an assembly by having their tail-end passed through a preformed hole prior to being deformed with the use of a tool. This deformity results in a second head being produced at the rear of the assembly, requiring the individual to conduct the deformation from the opposite side of the assembly. With a blind rivet, however, a tool may be used to pull the mandrel against the hat, allowing for pressure and expansion to increase until the rivet is fully installed.
