Electromagnetic relays are a common form of electronic control device for circuits, providing management through automatic switching that occurs based on current conditions. Such relays feature a control and controlled system, those of which are respectively known as the input and output loop. With a small current, electromagnetic relay are able to govern a larger current with a higher voltage. With this simple role, electromagnetic relays are used for safety, conversion, and adjustment.

Although many aircraft designs are moving toward jet turbines as their source of thrust, there is still a non-negligible number of vessels dependent on propellers. The propeller design was the first to be implemented on airplanes and has not changed much in its century-old history. When building or repairing an aircraft, one of the most critical factors in determining performance is choosing the right propeller. This determination is entirely-application based, and it is important to know what metrics are involved in choosing an optimal propeller. In this blog, we will discuss everything you need to know about propeller selection.

Aircraft contain complicated electrical systems that are used to transmit data and signals to power up electrical devices through a complex assembly of wires both within and between systems. Since wires are an intrinsic component of all modern aircraft, they should be shielded to protect their core from getting damaged, especially from the flayed ends of the holes through which they are threaded. This is where grommets, not to be confused with eyelets since they share similar functions, come into the picture. Grommets are made of metal, rubber, or plastic, and they are used to protect the holes through which the wires pass. In contrast, eyelets are used to stabilize the sharp edges around the holes. Thus, seeing how grommets and eyelets are fundamental to aircraft safety, this blog shall shed more light on the functionalities of each and explore the differences between them.

Aircraft fabric fasteners are the materials utilized for covering open structures in aircraft. All the supporting materials used during aircraft fabric covering and repairs have to be approved by the FAA, ensuring their airworthiness and reliability. In this blog, we will talk about FAA-approved aircraft fabric fasteners commonly used for fabric covering and their benefits.

Heat shrink tubing is a standard product used in various electrical setups to protect electrical parts from moisture, dust, abrasion, and sharp objects which can damage wires and other electrical components. Heat shrink tubing also helps secure loose binding cables, connectors, joints, and terminals to create organized bundles. In addition, color-coded heat shrink tubing may aid in facilitating wires and the identification of similar components.

Serving as the world's most complex vehicle, the airplane is made up of many parts. As an example, the Boeing 747 contains roughly 6 million individual components. When considering all parts, some play a more significant role than others in holding everything together or for providing safety during flight, such as structural panels and fasteners, for instance.

Radial ball bearings are friction reduction components that are equipped with the ability to carry loads radially around their axis. Serving as a subtype of ball bearings, their design consists of lubricated steel balls that are placed between two grooved rings. As such, they are often called deep-groove bearings or Conrad bearings.

Bearings are an important element of countless systems and machinery, serving to facilitate motion while mitigating friction for the health of the assembly. There are many types of bearings that one may utilize, each varying in its design and capabilities to cater towards certain applications. Needle roller linear bearings, sometimes just called needle roller bearings, are a common component that may be found within automotive and industrial power transmission applications alike. With their compact profile and ample load-carrying capacity, such bearings are quite beneficial.

Can aircraft survive a water crash landing without sinking or capsizing? With the help of modern technology and emergency flotation systems (EFS), certain aircraft like military and large commercial helicopters can stay afloat. Reserved for deployment during controlled ditching or upon a water impact, EFS are designed to minimize the chance of losing an aircraft to water damage so that the vehicle can be saved or salvaged.

Threaded fasteners such as bolts and screws are common to countless assemblies, allowing for two or more pieces to be secured together with ease. When exposed to various forces such as vibration and shock, such fasteners can often become loose over time. To prevent such incidents from occurring, specialized components known as locking fasteners may be used. Generally, these are components that are specifically designed to prevent loosening through various locking schemes. In this blog, we will discuss the most common forms of non-permanent locking schemes, allowing you to find the most optimal locking fasteners for your needs.
