Machinery often holds pressurized liquids or gasses, and the mating surfaces between such components routinely feature an O-ring or lip ring. While both of these components seal mating surfaces to prevent leaks, they are slightly different from one another. Those interested in learning more about the differences between O-rings and lip rings are encouraged to read the following blog.

When you are working with a hydraulic flow system that depends on fluids, it is important to have a means by which to control the water as it travels. Whether by regulating flow or pressure, flow control valves allow for control over a fluid system, and they typically react to signals generated by flow meters or temperature gauges. Depending on the specific industry and application in which your control valve will be used, different designs with varying levels of complexity are available.

Aircraft come in a large variety of types, including helicopters, airplanes, seaplanes, hot-air balloons, and more. Despite their differences, all of them require some sort of landing gear that is built to handle the force of landing, wherever that may be. More than just satisfying your curiosity, knowing the different types can answer several major questions about why certain aircraft require one type of landing gear over others.

One of the most complex stages of flight includes approaching the runway and landing at the end of it. Ensuring you do this properly guarantees the safety of passengers and air crew alike. However, there are some visual limitations that prevent pilots from taking advantage of any external visual cues. Luckily for us, the Instrument Landing System (ILS) aids pilots in achieving safe approaches and descents towards the landing area in any given situation.

While you may be familiar with the general concept of propeller aircraft and propeller engines, you may not be aware that they are often separated by whether they are designed with a pusher or puller configuration. Both types of layouts come with their own advantages and disadvantages, and the choice between both will often come down to the specific goals and intended application of the design. In this blog, we will discuss the differences between pusher and puller propeller aircraft, allowing you to have a better idea of what each is and which might be best for your needs.

In an electric circuit, a relay is a component used to switch electrical contacts. Specifically, a relay is an electromagnet containing an internal spring-loaded lever. The spring, or coil, energizes the relay by conducting either an alternating current (AC) or direct current (DC) around the core. This small current in turn magnetizes the core which attracts the lever to switch a large electrical current between contacts. The initial current can be sourced from a few places, those of which include another switch, the circuit board the relay is on, or another electrical circuit. To further understand the applications of a relay, this blog will explore the difference between alternating current and direct current as they function to control current through a relay coil.

Bearings are a staple hardware component of assemblies with moving parts, acting to facilitate motion while deterring the amount of friction that is generated during standard operations. There are many types of bearings that may be used for projects, the choice often varying based on the assembly in question and the various loads or forces that it may feature. Ball bearings in particular are one of the most widely used subtypes, finding regular implementation in rotary applications as a result of their ability to provide smooth motion while loads are optimally transferred.

At its most basic form, an aircraft must be able to generate movement, land safely, and maintain flight in various conditions. Dating back to the 1930s, the basic design of aircraft has stayed generally consistent, with engines and other parts following the same general rules of design. The fuselage is the main body of the aircraft where passengers reside and enter through a door or doors that seal at high pressures. The empennage is directly behind the fuselage and the wings are attached to either side. The tail group in the rear houses steering controls such as the stabilizers and the elevators. This blog will examine the general layout of an aircraft and the main components of the complex systems involved with flight.

Aircraft landing gear, often dubbed wheeled undercarriage, consists of brakes, wheels, tires, hydraulics, and energy-absorbing components. Different aircraft landing gears are designed to withstand an airplane's load during landing and surface operations, and are attached to the plane's primary structural configuration.

As aircraft have made it possible for adventure-seekers to travel the world within hours, commercial flight is becoming increasingly privatized for travelers that do not want to deal with airport delays, crowded gates, lost baggage, and more. In fact, private jets are taking over the aviation realm, providing customers a smooth and intimate flying experience. That being said, the world of private jets revolves around mission-based designs, some of which include super fast, ultra-long range, and luxury-focused variations.
