Cupped washers, also known as dished washers or Belleville washers, are a unique type of washer used in various applications to provide a spring-like effect in fastening assemblies. These components play a critical role in ensuring that fastened joints maintain their integrity under different loads and conditions. In this blog, we will delve into the role and functionality of heat sinks, which is crucial for anyone involved in designing, building, or maintaining electronic systems.

Cupped washers are distinguished by their conical shape, which allows them to compress and deflect under load. This design enables them to act as springs, providing a consistent tension in a joint. Unlike flat washers, which merely distribute the load of a bolt or screw, cupped washers add a level of elasticity to the assembly. This elasticity is particularly useful in applications where vibrations or thermal expansion and contraction could otherwise cause the joint to loosen over time.

In the realm of fluid power systems, pneumatic and hydraulic valves play crucial roles, with each type being tailored to specific applications and operating conditions. While they both control the flow of fluids within a system, there are significant differences between pneumatic and hydraulic valves that stem from the properties of the mediums they handle, which we will cover in this blog.

To understand the variances between pneumatic and hydraulic valves, let us begin by discussing the former. Pneumatic systems as a whole utilize compressed air as their working fluid. This air is typically generated by a compressor, which pressurizes the air to a level suitable for the application or need. Pneumatic valves, therefore, are designed to regulate the flow of this compressed air within the system.

Popularly known as planar cables or flat ribbon cables, ribbon cables are wide, flat, rectangularly shaped cables that resemble ribbons. Generally, each ribbon cable features a parallel wire that runs on a flat plane; this distinct design allows them to be used in compact operational environments. To learn more about these electrical components, this blog will provide a brief overview of how ribbon cables work and where they are used.

Rain, snow, and ice create dangerous conditions for the majority of vehicles. Airplanes in particular are impacted by icy conditions because when there is moisture in the air, along with freezing temperatures, ice can quickly build on airfoils, air inlets, and leading edge surfaces. Water droplets in the air are supercooled to below freezing temperatures, and when the surfaces of an aircraft disturb these droplets, they turn to ice. To learn more about aircraft ice control and detector systems, read through the following blog.

PVC valves are an essential aspect of countless plumbing and fluid systems, allowing for the flow of water to be managed in various ways through sealing capabilities. While such valves all perform a similar role, they can vary in their specific styles. As such, it is very important that one determines what type of valve is best for their given operations and needs, ensuring optimal performance and safety. In this blog, we will discuss PVC valves and their common variations, allowing you to have a better idea of your potential options.

Connectors are essential for most electrical devices and systems, serving to establish connections for the transfer of audiovisual and power signals alike. Depending on the application in question, one may take advantage of various electrical connector types, as each will tend to vary in its design, capability, and space restrictions. One common type of electrical connector is the D-sub type, that of which is known for its D-shaped metal shield that protects the contacts. D-sub connectors may be male or female, depending on whether they have pins or sockets. Nevertheless, the two types will always be designed in such a way that they can mate with one another to ensure signal transfer.

Lubrication is a process that controls the effect of friction and reduces the level of wear experienced by two or more surfaces that are in close contact to each other. There are a myriad of substances used as lubricating agents, but the most effective are oil or grease-based. Often employed in various machinery, lubrication systems deliver a precise amount of a particular lubricant when the machine is in operational mode.

Electric fuel pumps are tools used to power automotive engine systems by providing fuel through electronic means. The electric pump is an innovation that came about after WWII, making care for such components more efficient, reliable, and affordable. Since then, it has served as an alternative to manual fuel pump systems and is widely considered more convenient for the function and operation of motor vehicles.

Since the world of aviation has so many acronyms, it can be confusing to distinguish important terms from one another, and V speeds are no exception. With “V” meaning “velocity,” V speeds are defined as the standard airspeeds that each aircraft can operate at while achieving the highest possible performance level within safety standards. That being said, V speeds are determined by manufacturers once they have performed test flights and have identified an aircraft’s limitations. The main focus of these test flights is to provide pilots with insight as to the best practices for the operation of the aircraft they are flying.

An aircraft transponder, short for transmitter-responder, is an electronic device that transmits a four-digit code, or squawk code, enabling aircraft to be identified by Air Traffic Control (ATC). In the cockpit, pilots enter this code, which is assigned to them by ATC, into the transponder. Once this has been done, the aircraft is displayed on the Air Traffic Control radar screen.

A rectifier is an electronic device that converts the power generated by an engine, APU, or Ground Power Unit (GPU), typically, 120V AC to 28V DC power for various electrical components available in aircraft. The most common type of rectifiers used in aircraft are dry disk rectifiers and solid-state rectifiers. As commonly used rectifying methods in modern aircraft are half-wave and full-wave, we will be looking at these particular methods in more detail to better understand how they compare and contrast.

As aircraft continue to advance with new and improved technology being implemented all the time, many models are becoming increasingly electrified. While early aircraft were primarily mechanical, modern assemblies take advantage of electrical systems to position flight controls, measure atmospheric conditions, drive HVAC systems, and much more. Magnetism is another major element of aircraft system operations, magnetic fields often being used to create energy and power that is necessary for electronic systems to function as intended. As a result of the extensive use of electronic components and magnetic fields, it can be useful to have an understanding of electromagnetic induction and its effects.
