Before we can dive into how turbofan engines work, we need to first look at the core functionality of a turbojet engine. This is because the only difference between the two is an added fan placed in front of a turbojet’s core engine. This fan is encased in its own inlet and increases airspeed and thus pressure, ultimately resulting in an increase in overall exit thrust. This enhancement occurs without the need of additional fuel, making turbofans the engine standard for airliners because of their fuel efficiency. There are four main parts of a jet engine that air flow passes through that need to be explained to understand just how thrust is produced. These parts are where air enters an engine inlet and meets the compressor to, when it passes through the combustor, turbine, and exits out the nozzle. Read more >>

Aircraft spacers are used to guide wires, keep conflicting wires separated and hold wiring bundles in place. Wire organization is key in aircraft assembly to avoid electrical system malfunction and ensure the longevity of installed wiring. These spacers can be tubing, shafts, piping, or part fitters and come in a wide variety of shapes, sizes, and materials. Their shape can be hinged, hexagonal, cylindrical or flat and some materials used in their manufacturing include steel, aluminum, brass and synthetic materials such as nylon, rubber and plastic.  Read more >>

Within aircraft, there are a multitude of systems that utilize hoses. Hoses can be installed for fuel lines, hydraulic systems, brakes, oil coolers, and more. Flexible aircraft hoses in particular are important in situations where parts may be subjected to vibration or the hose system needs a lot of flexibility. In this blog, we will discuss some of the important considerations and steps that should be taken into account when purchasing and installing a flexible aircraft hose. Read more >>

Hydraulic systems are a widely used, reliable, and cost effective method of creating motion and actuation for various components. They can be utilized for car braking systems, aircraft flight control systems, industrial machinery, and much more. Simply put, hydraulic systems work by pressurizing liquid in an enclosed space, which in turn transfers that pressure equally through the system which can be used to perform various tasks. With hydraulics, it is important that that pressure remains equal and there is a backup in case of leakage or failure. To prevent and solve this problem, many hydraulic systems utilize hydraulic bypass valves. Read more >>

When you’re dealing with complex, highly-engineered, and expensive aircraft, it is important that every single piece does its job. From the engine down to the smallest fastener, each part has an important role to play. Bolts, a small but critical fastener in the construction of any aircraft, are no different. The stress of flight means that non-aviation grade hardware simply doesn’t do the trick. It has neither the strength nor the corrosion resistance to work effectively in flight. This has required aviation authorities to develop strenuous standards for aircraft bolts, as well as an exhaustive description and coding system. Read more >>
