When aircraft travel at the high altitudes that are standard for flight operations, the lack of oxygen pressure present in the atmosphere can create deadly environments for unprotected humans. As such, the negative effects of low atmospheric pressure are combated through manipulating air. Whether through increasing air pressure for more optimal breathing or by increasing the presence of oxygen within air mixtures, safe and comfortable environments may be achieved for the benefit of all operators and passengers.

When conducting military operations with aircraft, there are some times in which a particular unit needs to extend its natural range and cover large distances for travel. As fuel tanks are finite in their storage, most aircraft will eventually reach a point in which they need to land and refuel. For some military aircraft, however, advanced technology has allowed for refueling to be conducted mid-flight, permitting an aircraft to continue operations without the need for a landing. While seemingly simple at face value, mid-air refueling requires high amounts of pilot skill and specialty equipment to carry out the procedure.

Within the realm of material handling and construction, rigging refers to the process of setting up materials for lifting and transportation. Through the use of rigging equipment and lifting, the movement of heavy materials can be made quick and efficient. As such, enacting safe and proper rigging for a material handling operation is crucial. To best enact safe practices with rigging equipment, gaining an understanding of what common hardware pieces are and their functionalities should always be the first step for operators. In this blog, we will provide an overview of some of the primary rigging hardware pieces used in material handling, allowing you to improve your operations.

With countless aircraft operating throughout the night across the globe, external lighting on aircraft is important as to provide safety to pilots and others during flight. On almost all aircraft, various types of external lighting may be implemented in order to fulfill various purposes such making the aircraft more visible to others, assisting the pilot with more visibility during critical flight phases, or to provide light for others uses. In this blog, we will provide an overview of the various types of external aircraft lighting, allowing you to better understand their use and importance.

Hydraulic systems are used in a broad range of markets like aerospace, defense, marine, agricultural, plant, automotive, and more. For example, in aircraft, hydraulic systems are used to operate landing gear, flaps, flight control surfaces, and brakes, just to name a few. They generate power by utilizing pressurized liquid through a group of cylinders, hoses, and valves. The complexity of a hydraulic system ranges from those in small aircraft, which are used for manual operation of brakes, to sizeable transport aircraft with large, sophisticated systems. Although the vast majority of a hydraulic system is composed of cylinders and hydraulic hoses, there are many lesser-known accessories which are just as critical to the proper operation of the system. These accessories are pressure switches, hydraulic seals, pressure filters, flow indicators, and plugs. This blog will explain each one and its greater role in the hydraulic system as a whole.

Either prior to takeoff or following landing, taxiing is part of every flight. Whether a small private plane or a Boeing 787, all aircraft must be able to turn while on the ground. There are three main controls that help an aircraft turn: the brakes, rudder, and the tiller. In smaller aircraft, control surfaces are linked to the cockpit controls through a mechanical linkage. So, when the pilot pushes the right rudder pedal, the cables move such that the rudder deflects to the right. In large aircraft, this process is usually carried out by a computer. To help swing the nose in the correct direction, brakes are applied in the direction of the turn.

The air probe is sometimes referred to as an air evaluation, air plug gage, air axle or mandrel. It is built up of a precise and grounded solidified steel body that consolidates for (at least) two air gage spouts. In other words, it is a measuring device that tests the amount or degree of air is passing through to a nozzle. The way this works is by having air sent through the test body to the spouts where a back weight or back pressure is then created by the outside of the workpiece. The shield that can form as a result is punctured which then allows gas or air to stream into the sensor. When utilizing an air/gas test, maintenance workers ensure the test materials are perfect with the gases present in the air that will be measured. These surface tests are utilized to measure the temperatures of surfaces. For a detailed look on such air probe parts, read the article below.

The primary forces that act on an aircraft and affect flight are thrust, drag, lift, and weight. The understanding of and ability to control each of these forces is crucial to proper and efficient flight. This blog will define each of them, provide insight into what makes these forces occur, and describe how they affect an aircraft during flight.

From small consumer products to heavy duty industrial equipment, springs are found in all types of machinery. A spring is a storage device for mechanical energy and is most commonly classified by the way a load is applied to it. Springs have three basic types: compression spring, extension spring, and torsion spring. Compression springs are designed to operate with a compressive load. These are found in things like shock absorbers, spring mattresses, mechanical pencils, and retractable pens. Extension springs are intended to support tensile loads. A fun example of this spring is the Slinky, though they are also found in luggage scales and garage door mechanisms. Torsion springs are designed to operate with torque, and are found in items such as clothespins and mouse traps.

When acquiring new marine engine parts for your vessel, you first have to consider what you most want from the new parts. Some may prefer the power or efficiency, but for many consumers, they are looking for life expectancy. Regardless of whatever type of marine engine that you acquire, the life expectancy is largely dependent on the adverse conditions that surround the engine. If the engine is well maintained, the part can run at great capacity within  1000 hours without any major issues. Some of the more advanced versions even have the capacity to run on up to 1500 miles.
