A relay is an electrically operated switch consisting of a set of input terminals for one or more control signals and a set of operating contact terminals. The switch can have any variety of contacts in multiple contact forms, such as make contacts, break contacts, or combinations of the two. There are many types of relays classified based on their function, applications, configuration, structure, and more. This blog will look at the most popular types of relays.

Within the electronics industry and electronic manufacturing, resistors serve as one of the most common parts of a circuit. As a passive electrical component, a resistor provides electrical resistance in order to mitigate current flow, divide voltages, change signal levels, and more. Due to their ability to control current and protect components, resistors can serve a variety of applications for electronics. As the oldest form of resistor, the wire wound resistor in particular is one that has served many applications reliably over the years. Though simplistic in its nature and construction, the wire wound resistor is utilized for a multitude of high power circuits, ranging in application from current sensing to space & defense products.

When aircraft operate through cold winter months and hot summer days, the aircraft HVAC system is important for maintaining the comfort of passengers within the cabin. Beyond temperature control, providing a steady supply of air to the cabin also ensures that there is an optimal amount of pressure within the cabin, all while maintaining hygiene through the cycling of older air. In this blog, we will discuss the aircraft air conditioning system, allowing you to better understand how passengers are kept comfortable throughout a flight regardless of the environment outside.

You might have taken note of a few things during your flight travels or when you gaze up at a night sky. The one thing you will definitely have noticed is that the aircraft is geared with a number of illuminating lights. If you are the more detail-oriented type, you might have even noticed that planes flash different sets of lights during landing and takeoff. If you’re an inquisitive type, you probably asked yourself what might the intention and design be behind this design, what does the positioning and different colored lights mean? If you are curious to find out or if you are entering the aircraft industrial industry and want to brush up your knowledge, read the article below and find out why such aircraft lights were put in place and how they air with flight crews.

Air bearings, also known as aerostatic or aaerodynamic bearings, are fluid bearings that utilize a thin film of pressurized gas to provide a low-friction, load-bearing interface between two surfaces. The two surfaces do not touch, therefore avoiding the traditional problems bearings face such as friction, wear, particulates, and lubricant handling. These differ from ball bearings, where the balls are in constant contact with one another and form a solid bridge between the machine elements. Air bearings offer a number of distinct advantages in precision positioning and high speed applications, where they lack backlash and static friction.

Typically, a specific but basic light pattern is required of most marine vessels so that they can be used to show other boats where they are positioned during foggy weather and can among other things prevent boat crash incidents. In the same way that aircraft must have a specific set of patterned lights that alert neighboring aircraft of their position, so too do boats and other marine vessels have various navigational marine lights. For more information on this, read the article below. 

When it comes to construction, early bridges and aircraft are similar in that a number of rivets are used for assembly and for securing infrastructure. In more recent years, many bridge builders have turned to welding instead, forgoing the rivet for new techniques. Despite this, aircraft continue to be manufactured with the use of aircraft grade rivet technology. This is due to the specific stressors and operations that aircraft undergo, requiring rivets to remain safe and intact.

The design of a steam turbine is a very complex endeavor that requires in depth knowledge from many fields of engineering. The development of such a machine is a big investment that is important and crucial for the current economy climate. Micro gas turbines and steam turbines will continue to be present in the industrial manufacturing and aviation sector. The technological innovations currently being developed will continue to improve the efficiency and longevity of steam turbines. For a basic look on micro gas turbines and steam turbines, read on below. 

We’ve discussed aviation lighting when it comes to commercial flight, but what we have not yet gone over are the lighting signals that can be found on helicopters. While a red and green light on a plane might mean one thing, it can signify something totally different on a helicopter. Read on below for more information on the lighting that can be found on helicopters. 

Aircraft deicing is somewhat similar to how one might deice the windows of a car before driving. In concept they are the same, but in practice is where you start to see the differences. To understand those differences, it’s best to first establish what aircraft deicing is and why the need for aircraft deicing systems parts is so important. Aircraft deicing is a procedure involving the heating and applying of deicing fluid onto the aircraft windows and wings. The need is important because this procedures allows for the safe removal of ice or snow that has been frozen onto the aircraft and, if not removed, could compromise the safety of its next flight.
