During standard operations, aircraft engines make loud noises that can be heard from far away. This continual and often disruptive aircraft noise can cause several issues for those living and working nearby. One primary concern is the health status of airfield employees who are constantly exposed to the loud sound of engines cutting off or surpassing their capping speed during takeoff/landing procedures.

Despite needing power for tests, turnovers, and other processes, engine operations can put surrounding individuals and buildings at risk with various safety hazards. As a result, operators must take advantage of either an Auxiliary Power Unit (APU) or an Aircraft Ground Power Unit (AGPU). Despite these options, some aircraft may not feature an APU, and APUs are loud during operation and utilize engine fuel. As such, the AGPU is the optimal option for powering aircraft electronics while the aircraft is situated on the ground.

In the realm of motion control, permanent magnets are a fundamental component that assist in the functionality of couplings, motors, stators, and other various components. Generally, magnetic assemblies provide torque and motion that is ample enough for standard system operations despite their compact packaging. As permanent magnets can present various safety concerns when they begin to reach the end of their service lives or when damaged, it is important that they are well maintained and protected. In this blog, we will discuss the common materials that are used for magnetic assembly construction, as well as some of the various safety precautions that should be followed to prevent hazardous conditions.

Rotors are components that are found in various assemblies and machinery, used to transform electric or electromagnetic energy into rotational motion. In order for such equipment pieces to perform optimally, they must maintain an even balance and distribution of weight across their rotational axis. The unbalancing of weight on a single side can happen to rotating parts of any assembly, and uneven mass distribution will result in the misalignment of a component’s rotation center in regard to the geometric axis. This can deter proper efficiency and safety, and as thus proper balancing should always be maintained. With rotor balancing, noise, vibration, and other various issues can be deterred for the health of a system.

Like a transformer used to distribute power for residential and commercial purposes, an audio transformer functions similarly and is specifically designed to be implemented in audio circuits. Used to carry audio signals, audio transformers are electromagnetic systems applied to provide corresponding parts with filtered input and output signals. Within this blog, we will go over the different types of audio transformers and their primary functions.

Used to simultaneously control multiple in-flight functions automatically, autopilot systems are growing in number among many modern models of fixed-wing aircraft. Though not in all aircraft, autopilot systems and the components that comprise them can also be found in electric vehicles, ships, spacecraft, and more. Specifically in aircraft, the parts that make up the autopilot system frequently encompass items that track, maintain, and adjust trajectory in place of the pilot. Within this blog, we will highlight the main devices that comprise an autopilot system, how they assist a pilot in flight, and why they are growing as a staple within the aviation industry.

An electron tube, vacuum tube, valve (Britain), or tube (North America) is a device that is capable of managing the flow of electric current in a high vacuum. Before the advent of semiconductor technology, electron tube parts were present in countless electronic circuits through the first half the 20th century. While they originally served numerous applications such as early televisions and digital computers, they can still be found in a number of military and aviation assemblies to this day due to their consistent advancements and unique capabilities.

A bearing is a hardware component that serves assemblies in friction mitigation, and they can come in a variety of types depending on the need of the assembly. Roller bearings are a common variation, and they utilize rolling elements placed between races in order to minimize the forces of friction. Roller bearings are the oldest form of rolling-element bearing, and they come in a few common forms. The cylindrical bearing in particular is one in which cylinders are used as the rolling element. As bearing parts that excel under high speed and heavy radial loads, cylindrical roller bearings may be very beneficial for a number of applications.

The cockpit is the section of an aircraft that provides visibility to the front and sides while housing the pilots and other crew members. The cockpit also contains the display, control, and communications equipment that crew members need to operate and navigate the aircraft on the ground or in the air, talk to ground facilities or other aircraft, and monitor or control onboard systems and equipment such as engines, fuel tanks, air conditioning, and so on. In this blog, we will discuss cockpits in detail.

A Zener diode is a type of diode designed to allow current to flow backwards once a certain voltage, known as the Zener voltage, has been exceeded. Zener diodes are used throughout electronic equipment of all types and are considered a basic building block of electronic circuits. Due to their ability to reverse a portion of a current, Zener diodes offer many advantages over traditional diodes.

Despite not being essential for flight, landing gear is among the most critical components of any aircraft. In fact, landing gear makes up approximately 7% of an aircraft’s weight as well as 20% of its maintenance costs. The largest manufacturer of aircraft landing gear is Safran Landing Systems, who operate worldwide. The process of producing landing gear components involves precise engineering of high-quality materials. For example, the strut, considered the heart of the landing gear, is machined out of a solid column of high strength steel. In this blog, we will discuss the main functions of aircraft landing gear.

Stud bolts and hex bolts are used throughout the petroleum and chemical industries for flanged connections. The stud bolt is a threaded rod with two heavy hexagon nuts, while the hex bolt features a head with one nut. Nuts and heads are both six-sided. The amount of bolts needed for a flange connection is determined by the number of bolt holes in the flange. The diameter and length of bolts depends on the flange type and the flange’s pressure class. Stud bolt lengths are determined by ASME B16.5 standards. The length, in inches, is equal to the effective thread length measured parallel to the axis, from the first thread to the thread without chamfers (or points). The first thread is defined as the intersection of the diameter of the thread with the base of the point.
