Industrial springs are common hardware components that are often overlooked, typically being mounted within an assembly of moving parts. Crucial to motion control and industrial equipment, industrial springs may be found in door closing systems, the mechanical seals of rotary unions, and much more. While there are numerous types of industrial springs that one may use, the most common variations that serve industrial applications include compression, extension, and torsion springs.

Compression springs are a type that are capable of resisting axial compressive forces, serving as the most efficient type in regard to energy storage. As force is exerted on the spring, the component will begin to compress and build up energy. Once the spring is able to return to its standard position, the built-up energy is released against the load, pushing it back. A common type of compression spring is the wave spring that of which features a flat wire with waves at each turn. With their availability to provide high force while having a lower working height, such devices serve vibration isolators and bearing retention applications.

Extension springs differ from compression springs, serving to resist the tensile forces that pull them apart. Through the use of coiling, initial tension is provided. This ensures that the spring exhibits pulling forces when extended for the means of returning to a resting state. With loops or hooks situated at each end of the spring, components can be attached and held together through the force of the spring. While compression springs feature zero load while at zero deflection, extension springs have a load at zero deflection as a result of their initial tension. For their industrial applications, extension springs may commonly be found on medical devices and automated equipment door mechanisms.

Torsion springs are a more specialized type as compared to the compression and extension spring, featuring resistance to twisting forces rather than compression or axial tension. For their construction, such springs are helically wound, featuring arms on each end that rotate around the component’s central axis. The arms are always attached to various components, allowing for a load to be exerted on the spring itself. When an application requires a high amount of torque for proper functionality, two torsion springs may be paired with a space between the two. These assemblies are known as double torsion springs. While torsion springs are very common, one typical use is to be used as a clothespin.

In the realm of aviation, industrial springs find many uses on an aircraft. Within the landing gear, compression springs are found within poppet returns, slat servos, and slat controls. Meanwhile, extension springs facilitate the operation of boom latches, automatic patch levers, and other various systems. With the use of a torsion spring, tall cone levers, passenger door entrances, and other parts can operate with ease. As a result, having various industrial springs on hand can ensure the continued operation of countless aircraft systems and components, proving their use and importance.

Exhaust systems are undoubtedly the bowels of any vehicle, automobile, or aircraft. The main function of the exhaust system is to allow for the smooth propulsion of gas emission from an engine out to its surrounding environment. This allows for proper gas exchange to take place in order to optimize fuel usage and energy output. In theory, this function could be performed by any metal tubing that leads from the engine to the tailpipe, however, there are many other requirements that must be considered in order for an exhaust system to function effectively. According to Federal Aviation Association (FAA) regulations, the exhaust system of an aircraft must be able to withstand high temperatures, corrosion, vibration and inertia loads, and must have means for flexibility in addition to performing its typical roles.

A structural aspect that must be put into consideration in designing an exhaust system is the maintenance of back pressure. The engine propels outward, creating a pressure that flows out. However, if there are too many bends, or if the piping of the exhaust system is too small, then the air pressure could build up in the opposite direction of the exhaust system, creating what is known as “back pressure”. The higher the back pressure, the more energy is needed for the exhaust to expel the gases outward. If the back pressure is higher that of the exhaust system, then the back pressure completely cancels out the exhaust and nothing gets expelled. To prevent this, exhaust pipes need to be wide enough and allow for optimal air flow. If pipes are too wide, not enough pressure will be built up, and the air will move too slowly.

Another consideration for a properly functioning exhaust system would be the routing of the exhaust pipes. Commercial aircraft exhaust can reach temperatures of 2000?, which can melt the cowling and other parts of the engines. The exhaust pipes must be designed in a way that is clear from areas that are unable to withstand such temperatures. The cowling around the engine may need adjustment in order to allow for adequate room for proper routing. However, it should also be noted that there will be a large difference between top temperatures of commercial planes and experimental builds.

Although not as important, you should be mindful of how much noise your aircraft creates. The sudden expulsion of air from any source can result in an audible sound, whether that be flatulence or exhaust. The engine is the lifeline of an aircraft, but the process of carrying away gas from the engine system can result in very loud sounds. This is why zero emission cars, such as any of the Tesla automobiles, create little to no sound when in use. Loud noise can be a distraction for pilots and pose as an overall safety concern. Unfortunately, the sound created from an aircraft is largely influenced by the structure of the exhaust system.
