When securing materials together for an aircraft assembly, mechanical fastening serves as the most commonly used method. Fasteners are hardware devices that can affix parts together in a permanent or non-permanent fashion, and they can come in a variety of shapes, sizes, materials, and types to accommodate different needs and structures. Regarding the construction of aircraft, rivets, bolts, nuts, bearings, and other fasteners all work together to provide rigorous assemblies that can withstand the forces of flight.

Actuators are important components for the operation of machinery, allowing for actions to be carried out through the use of control signals and energy. From the simple operation of opening a valve to rotating an automobile wheel, actuators serve many roles and applications with their various types. Additionally, actuators can be powered through multiple means such as hydraulic pressure, pneumatic pressure, and electrical current. Due to their simple but crucial role in the operation of machinery and systems, understanding their functionality and varying types can be useful for ensuring that the right components are chosen for a given application.

Diesel engines serve as the source of power for huge machines like trucks, trains, ships, submarines, and more. On the surface, they are highly similar to the more common gasoline engines. Despite this, they operate in a slightly different way, generate more power, and do so more efficiently. This blog will explain diesel engines, how they differ from gasoline engines, what makes them more efficient, and their other advantages.

When selecting the rotary actuator for your system, among the most important design considerations are mechanical efficiency, package size, shaft options, max rotation, and cost. Apart from these, you must also consider characteristics including backlash, load-stopping ability, and its ability to handle both axial and radial loads on the shaft. There are two main types of pneumatic rotary actuators: rack & pinion and vane actuators. This blog will explain both types, as well as their pros and cons.

Torquing is the process of tightening a fastener to the ideal level. Though it may not seem important on the surface, improper torquing of a fastener can lead to serious consequences as severe as damage to the entire structure, machine, or component it is installed in. Torquing to perfection is a difficult process which requires engineering-level expertise on how to handle fasteners. The effect of perfect torquing can do a lot to extend the service life of fasteners as well as the component it is used in. As a matter of fact, many premature structural failures are due to improper fastening. This blog will explore what torquing is, why it’s important, and how it is done.

Just like automobiles, aircraft of all types require regular maintenance and inspections for their engine oil systems. During flight operations, an aircraft may be exposed to a number of contaminants including dirt, sand, salt, and much more. These contaminants are important to remove from the system as soon as possible, as they may lead to corrosion, abrasion, and other damages that may affect the performance or service life of the engine oil system or surrounding components. In this blog, we will discuss some quick tips that can help you establish good maintenance practices and protect your aircraft.

Helicopters are a magnificently adaptable airborne vessel, equipped for supporting an expansive cluster mission from elevated emergency vehicle, to flying horticultural utilization of pesticides, to substantial lift and tower development. While agile and deftly noticeable all around, helicopters present exceptional difficulties to ground bolster work force accused of ground treatment of the airplane.

A common misconception is that oil filters and spacer oil strainers are the same thing. While this is not totally true, they do bear many similarities to one another. Their first similarity is the task they perform: to remove contaminants from oil as it passes through. Additionally, both filters and strainers protect downstream equipment by removing debris or contaminants that would otherwise compromise the integrity of the component. Both filters and strainers can be required by law or regulation for a variety of safety or environmental reasons, to improve the efficiency of the system, or merely for practical purposes. In many cases, the flowstream would be rendered useless without a filter or strainer.

Across the various helicopter models and categories used across the world, the two main types of landing gear that are most widely present are wheels and skids. Helicopter wheel landing gear typically consists of three or more wheels attached to the bottom of the helicopter, and the number depends on the intended operation and helicopter type. Helicopter skids, on the other hand, are long, fixed components that provide for similar landing abilities as wheels do. While each provides for their own advantages and disadvantages, there is no particular “better” choice. Wheels and skids both may benefit particular applications better than one another, and choosing between the two should depend on various factors of the helicopter in question. In this blog, we will discuss the differences between the two landing gear types, and the applications and helicopters that each serve best.

The Bernoulli principle defines how air velocity and air pressure are related to each other and how both work can work together to give something lift. An object must have "lift" to fly, a force which pushes it upwards. Because of a relation called the Bernoulli Principle, wings produce lift. In this case, the "wings" of a helicopter are the rotor blades. They rotate at high speed and therefore have apparent velocity relative to the air, just as plane wings do when moving forward. As the air moves over the blade it generates lift by deflecting the air and by the low pressure on top of the wing.
