When boarding a commercial airplane like a Boeing 737 or an Airbus A350, the first thing that becomes apparent is the sleek and streamlined shape of the vessel’s fuselage. In greater detail, these structural enclosures play a critical role in ensuring aircraft safety, performance, and comfort for all passengers and crew members onboard. In this blog, we will explore four common types of aircraft fuselages–truss, geodesic, monocoque, and semi-monocoque–to gain a better understanding of their importance in aviation.

Choosing the optimal fastener for a specific task requires an understanding of the limitations and benefits of the various devices available. Threaded rods are a type of long, cylindrical fastener that can be easily identified by their characteristic threading on either end. Given their reliability and utility in a wide range of projects, they are commonly employed as an alternative to conventional bolts, screws, and studs. In this blog, we will discuss the hallmark features of threaded rods, alongside their benefits and pitfalls.

The majority of large commercial aircraft feature two or four engines mounted in pods underneath the aircraft wings. However, securely attaching these engines onto an airplane wing requires a complex process and is not as simple as tightly bolting them onto the apparatus due to strict safety precautions. To learn more about how aircraft engines are fixed onto their wings, we encourage you to read on.

Valves are devices that are common to various systems involving the storage, transportation, or use of fluids, capable of controlling the flow rate of gasses or liquids. Whether one is using valves for pharmaceutical applications, food and beverage production, or countless other such operations, there are a number of valve types that one may choose from. One common option is the needle valve, which can manage the flow rate of clean fluids while offering low flow rates and significant pressure drops between the inlet and outlet. In this blog, we will discuss the needle valve in brief detail, allowing you to have a better understanding of its design, use, and functionality.

While much of the time and effort that goes into aviation design focuses on how to keep an aircraft in the air with as much efficiency and power as possible, it is almost equally important that it is able to effectively operate on the ground for takeoff, landing, and taxiing operations. While some aircraft may have skids for operating on water, a majority of modern aircraft feature wheel-based landing assemblies for maneuverability on hard-surfaces like those at runways and airports.

Air traffic management and control mainly involves the control of traffic in and around airports, terminals, and airspace. Working from air traffic control (ATC) towers, air traffic controllers are responsible for ensuring a safe distance between all aircraft in the air and on the ground to prevent accidents. To better understand the integral role that air traffic management control systems play in the aviation industry, this blog will cover their importance.

As commercial aviation continues to grow around the globe, many airports are facing a rise in traffic as aircraft takeoff and land throughout the day and night. With a higher frequency of movement, an increased need for security is required to ensure that every aircraft and all personnel, crew members, and passengers remain safe during operations. This necessitates the wellbeing and reliability of many types of equipment that aid pilots and the management of traffic. During low visibility conditions, one of the most important forms of equipment that increases traffic safety are airfield ground lighting facilities.

Instrumentation amplifiers, or amplifier instruments, are analog subsystems that amplify low-level signals when exposed to high common mode noise, or common mode voltage (CMV). These differential amplifiers are most effective for DC signals and are often characterized by high gain, high input impedance, and a high common mode rejection ratio (CMRR).

Aircraft are equipped with numerous components that allow them to operate optimally. For instance, aircraft require lift to achieve flight. While a majority of the lift produced by aircraft comes from the wings, a portion of it may come from another source: high-lift devices.

Pilots rely on four types of speed measurements when operating an aircraft: ground speed, true airspeed, indicated airspeed, and calibrated airspeed. The difference between airspeed and ground speed when discussing the speed of an aircraft is how the speed is measured. Ground speed is measured relative to the Earth below the plane while airspeed is measured relative to the air through which the plane is flying. Ground speed defines the measurement for how quickly a plane will reach its destination. Airspeed, on the other hand, provides a measurement for the effect of airflow on the plane’s ability to fly.

An aircraft engine is an apparatus that is paramount to carrying out powered flight, serving as the area where fuel-and-air mixtures are compressed and combusted for the means of generating propulsive force and thrust. With the constant ignition of mixtures that create intensive pressurized gasses, aircraft engines regularly face wear and tear over operations. As a result, it is very important that engines are regularly inspected and maintained so that any issues or defective parts can be remedied before they have a chance of becoming a hazard. In this blog, we will discuss the maintenance process known as an overhaul, that of which is a complex process that can extend the life of your aircraft if conducted correctly.
