To put it simply, a bearing refers to an equipment component that is utilized to control the movement and limit the friction of a mobilizing part. It reduces relative movement to limit the load placed on the machinery. True to its name (as the term “bearing” is a meld of the words “to bear”) the bearing certainly does bear many components in modern machinery. For a more detailed look at the many different bearing parts, you can read the article below and learn about the variety of options you may find in the bearing market, including but not limited to plain bearings, ball bearings, roller bearings, fluid bearings and magnetic bearings.

When operating an aircraft engine, an immense amount of internal heat is generated, sometimes even reaching temperatures around 2,000 degrees Celsius in certain engines. This is due to the process of fuel combustion that many engines utilize for producing propulsion. With such fuel ignition and heat generation, engines and their surrounding components can heat up very quickly, leading to damage if left unchecked. To mitigate this heat and cool down the engine to acceptable temperature limits, various aircraft cooling systems are in place. In this blog, we will discuss the various aircraft cooling systems that benefit different aircraft, and how they provide for temperature reduction.

To operate heavy, flight-pertinent machinery such as landing gear and main steam system valves, aircraft rely on the hydraulic system. With a hydraulic system, a small volume of fluids may be utilized to transfer high amounts of pressure and force. This is due to the incompressibility of fluids, allowing for force to be equally transferred throughout the fluid as according to Pascal’s law of hydraulics. For hydraulics to be successfully operated, they require the use of aircraft actuators.

Aircraft bolts are a type of fastener that is widely used across the assembly of an aircraft. Fasteners are a type of hardware that allow for two or more components to be secured together either non-permanently or permanently, and they are greatly utilized for aircraft construction. Aircraft fasteners such as the bolt are used in areas where there is a need for high strength that typical screws cannot fulfill. Depending on the application and need, different types of aircraft bolts with varying properties may be used. In this blog, we will discuss some of the main bolt types that are used for aircraft assembly.

A washer is a thin plate with a central hole used to distribute the pressure load between two attached surfaces. They are often used with nuts, bolts, or other fasteners to prevent them from being driven into the material of the surfaces to which they are affixed. General wear and tear from vibration and friction often causes standard threaded fasteners to loosen over time, but the lock washer is designed to resist this. This blog will explain how lock washers work, their types, and how to use them.

With the constant advancement of aircraft technology and global strive for a reduction in the aerospace carbon footprint, the aircraft actuator market is facing a rise in demand. Actuators are simply a component in which an action, movement, or other control can be conducted after given an operating signal. These operating signals can be given via voltage, hydraulics, pneumatics, or by manual human power. From landing gear to aircraft flaps, actuators are vital to a number of flight pertinent operations, and this number will only continue to rise.

The first half of the equation of flight has to do with three factors: lift, force and gravity. To dive into these factors, we need to look into the physics of airplane flight and Newton’s Third Law of Motion: for every action, there is an equal and opposite reaction. The main key here is balance. To achieve flight we must first create forward thrust and lift to generate air pressure beneath the wings that will, in turn, lift the plane. This lift must create an imbalance where there is more lift or force upward than there is gravity pushing downward. Airplane wings are shaped with an angle of attack that maximises the amount of air hitting the bottom of the wing. Too much tilt and the airflow around the wings becomes too choppy and irregular and a plane fails to sustain lift and fly correctly. A 15 degree tilt tends to be the maximum sustainable angle for aerodynamic flight.

From directional control to changes in altitude, an aircraft autopilot system can control many aspects of the flight, aiding the pilot when necessary, as well as making the trek smooth and efficient. Some may be surprised to know that aircraft can even control and execute a landing, though it is very uncommon. Less than 1 in 100 commercial airliner flights are ever landed through autopilot, and it is often reserved for times where visibility is extremely poor. Nevertheless, it is something that many planes are capable of doing, and it can be a very smooth and safe operation due to the expertise of pilots. In this article, we will discuss how autopilot is able to conduct landings by itself.

As aircraft burn large quantities of fuel during flight, the engines generate an intense amount of heat that spreads to the surrounding components. While half of this heat is flushed out as exhaust, the other half remains absorbed by the engine, posing a problem that could lead to damage of parts or even failure of the system as a whole. To mitigate this issue, aircraft utilize lubricant cooling systems to reduce the heat of the engine and its surrounding parts.

Aircraft come in many different shapes, sizes, functions, and applications. Because of this, varying materials are used depending on the plane’s performance needs. Early aircraft such as the Wright Flyer were built with wood and fabric. The aircraft frame was constructed with spruce and ash and much of the surface was covered with muslin, a plain cotton fabric. Modern aircraft are made from metal or composites like carbon-fiber and fiberglass, or a combination of these. Here is a rundown of some of the materials used in aircraft today.

As a plane descends and prepares for landing, it conjures an incredible amount of force around it. Planes are typically traveling at about 200 miles per hour when touching down on the runway; thus, they require a superb braking system. Even when idle, thrust is produced and travels forward as it acts against the deceleration systems. The braking system on aircraft are sufficient enough to stop most aircraft, yet in case of emergency, another deceleration method is needed for safety purposes and to prolong the longevity of the brakes.

Aircraft engines create an immense amount of heat throughout their flight hours. High temperatures necessitate the presence of cooling instruments. An important member of these components is the cowl flap. Dare I reference the Star Wars prequels, an activated cowl flap resembles a mini version of the walkway extended from Padme’s J-type Star Skiff ship in the last scene of Revenge of the Sith. Though a cowl flap doesn’t sound as flashy, the lowering mechanism works almost identically, and is a valuable cooling component.
