The COVID-19 pandemic unquestionably threw many industries into disarray. Commercial aviation was no different. In the early stages of the pandemic, an estimated 16,000 passenger jets around the world were grounded, reducing the amount of jets in service to its lowest point in more than 25 years. To give you an example of the severity of the dropoff in air travel, on January 22, 2020, there were more than 113,000 passenger flights. Just three months later, on April 22, there were fewer than 27,000. However, airlines are not the only companies being affected. Diminished demand has caused leading manufacturers like Airbus group to cut their production by more than thirty percent.

A flanged ball bearing is a configuration of a standard ball bearing that features an extension or lip on the outer ring of the bearing which is designed to aid the mounting and positioning of a bearing in a delicate application. Just as ball bearings are available in sealed or open, they are also available flanged or plain - a flange is simply another option for the design engineer or manufacturer. Flanged bearings are most commonly used in applications where the bearing must be locked in place. Depending on the application, the bearing will need to be locked axially (along the shaft) or radially (perpendicular to the shaft). In either case, a flanged bearing will help withstand axial thrusting.

A grinding machine, also known as grinder, is a machine tool used for grinding. Grinding machines use an abrasive wheel as the cutting tool, with each grain of abrasive on the wheel’s surface cutting a small chip from the workpiece through shear deformation. Grinding is commonly done to finish workpieces that must show high surface quality (surface smoothness) as well as high accuracy of shape and dimension. More often than not, grinding is a finishing operation because it can accurately remove minuscule amounts of metal, at depths of approximately 0.25-0.50 mm. Despite this, grinding is a diverse field and is used in some applications to rapidly remove high volumes of metal.

A damper is a valve or plate that controls the flow of air within a duct, chimney, VAV (variable air volume) box, air handling, or other airflow equipment. Dampers are sometimes used to cut off central air conditioning to an unused room, or to regulate it for room-by-room temperature and climate control. The operation of a damper can be manual or automatic. Manual dampers are activated by turning a handle on the outside of the duct. Automatic dampers are operated by electric or Pneumatic motors, which are in turn controlled by a thermostat or an automation system within the building.

Memory cards use what is referred to as flash technology, which is technology that can archive information and data even after the power is removed. Because of this innovative feature, memory cards are crucial in mobile phones and apps so as to preserve a user’s significant videos, photos, notes, etc. They can also be used to program data, but the major issue with Memory Cards module is being able to choose one of the many that are offered. Some offer more storage but one does wonder if that much storage is really needed. The answer relies on what you will be using this card for and for what device. If you are a casual vacationer for example, you may not need that much memory. If, however, you know that you will be taking many photos on your camera, then a memory card that can preserve a large package of photos is necessary. Below you can find a basic definition of the many kinds of memory cards that you may need.

Visual Flight Rules, or VFR, refers to a set of guidelines under which a pilot operates an aircraft in weather conditions clear enough for the pilot to see where the aircraft is going. VFR requires a pilot to be able to see outside the cockpit, control the aircraft’s altitude, navigate, and avoid other obstacles and aircraft. Different governing bodies have unique requirements for VFR flight, but factors such as minimum visibility and distance from clouds are always taken into consideration. The opposite of VFR flight is IFR, or instrument flight rules, in which the operation of the aircraft is done primarily through the use of instruments rather than visual reference. In modern aircraft, there are many instruments at the pilot’s disposal during both VFR and IFR flight. While VFR flight has the added bonus of visibility, instruments are still key. This blog will cover the primary aeronautic navigation instruments necessary for VFR flight.

When moving an aircraft away from the airport gate or out of a hanger, a towbar is an indispensable piece of equipment. Aircraft engines are powerful, thus if used in close proximity to equipment and structures, they can pose serious damage or safety risks. Engines are expensive to run, and thus it is not beneficial to spend fuel that is best reserved for takeoff and flight. Because of these concerns, towbars along with pushback tractors are used to safely taxi aircraft around a runway. As aircraft come in many types and sizes, choosing the Right Aircraft Towbar for your needs is important.

Heavy lifting is a necessary procedure in almost every industry and plant. Hoists are the main method of being able to move heavy loads and equipment. They often do this though vertical lift, meaning the load is lifted straight up without lateral swinging, and this is achieved through the use of wheels or grooved drums. In regards to electric hoists, the two main types that are most utilized by industries are Chain and Wire Rope Hoists. To choose between them, one should consider a variety of factors including the industry, load capacity, working environment, and more due to their different designs and abilities.

When piloting an aircraft, there are several inspections and checks that must be implemented before taking off. One of the various items to inspect on an aircraft before taking off is the rudder. This is because the rudder is vital for ensuring that you as the pilot are on the centerline of the runway. The right rudder, specifically, is responsible for preventing the plane from veering toward the left outermost edge. Should there be any issues with this part, the chances that your takeoff and landing could be impacted increases significantly. If there is ever an instance where rudder failure is an issue, the best strategy to implement is that which is pre-planned. For those unfamiliar with aircraft and the physics behind how they are able to take flight, it is important to understand why the rudder is so important. Knowing this will help in understanding the reason for an aircraft’s natural tendency to turn left. There are four reasons for this, those being the torque, P-factor, gyroscopic precession, and the spiraling slipstream. For a more detailed outline of these three factors, see below:

When we think of aircraft functionality, we tend to forgo the importance of the wheels and brakes. Although the main functionality of aircraft is to fly, wheels and brakes are what enable the aircraft to both start movement, and safely land at their various destinations. They are expensive and important components, and often are subjected to great deterioration with every flight. With wear and tear of any aerospace part comes the need for maintenance, repair, and overhaul (MRO).

For as long as there has been computing, there has been a need to store the information produced by computing as memory. In this blog, we will explore a brief history of computer memory, from its origins to modern day. The first type of computer memory took the form of paper punch cards. Punch cards were first used in 1725 in the textile industry, to control the mechanized textile looms. In the 1890s, Herman Hollerith used punch cards for census calculation for determining the population of the United States. Essentially a thick sheet of paper with holes punched through it, patterns could be imprinted on the punch card that could be interpreted by a machine. Later, they were used as an input device for computers up to the 1970s.

Memory in a computer is any hardware that can store data for any amount of time. If a computer memory is volatile, the information stored on the hardware is lost after the power source is disconnected. In contrast, non-volatile computer memory retains the stored information. Under these two broad categories are many subtypes of memory.
