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.

Aircraft are constructed to meet a specific set of requirements, and each component applied must be individually selected for a particular plane. This means that it is essentially impossible for any given aircraft type to share the exact same characteristics and design.

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.

Hydraulics are extremely useful for a number of applications, providing large amounts of power that can be used for actuating and driving systems. Hydraulics are also commonly exposed to numerous environmental conditions, often coming into contact with dust, dirt, debris, and other various substances. If these contaminants enter hydraulic cylinders and other assembly components, performance can be lost and such equipment may even begin to face damage. With the use of devices known as wiper seals, cylinders and other components can be protected from contaminants with ease.
