From the very first hot air balloon to modern commercial airlines, the aviation industry has gone through many great advancements since its emergence. To better understand the invention of aviation, we will first take a look back at several of the most important developments in engineered flight. The first rendition of man-made flight came in the 5th century with the invention of the kite in China. Then in the 15th century, Leonardo Da Vinci created the first drafts for a rational aircraft in his paintings. In later years, several more sketches and models were made, including a theory by Francisco Terzi, the father of aeronautics, that showed the possibility of flight in lighter-than-air aircraft made of copper foil cylinders. Then, following the discovery of hydrogen in the 17th century, the first hydrogen balloons were created, leading up to the invention and high popularity of hot air balloons from 1783 to the late 18th century. This ultimately led to the airship in the late 1800s.
While aircraft can be made from hundreds of thousands to millions of items depending on their size, they all relatively resemble one another once assembled. Consisting of 5 primary parts, the pieces that come together to create man-made flight include the fuselage, empennage, wings, powerplant, and landing gear. Constructed and ever-evolving to make flight as fast, efficient, and safe as possible, these components are held to strict maintenance protocols regarding their design and manufacture to ensure planes of any size are airworthy and ready for takeoff.
The wonder of flight would not be possible without the wing. From takeoff to landing, aircraft use their wings to steady and steer, so it would make sense that a plane with larger wings should perform better; however, the optimal size of an aircraft’s wing is dependent on a variety of factors. Some large aircraft require smaller wings which means they have what is referred to as high wing loading. The wing loading of an aircraft is calculated by dividing the total weight of the aircraft by the lifting surface area of its wings. Depending on the wing loading, aircraft will have different stall speeds and maneuvering abilities, as well as takeoff and landing performances. This blog will explore how wing loading works and the effects of this ratio on flight.
Pressure switches happen to fall under the category of “pressure sensors.” A pressure sensor is a device used for measuring the pressure of liquids and gasses.

Within the realm of aviation and fluid dynamics, turbulence is used to refer to fluid conditions in which pressure and flow velocity haphazardly fluctuate. With turbulence, air will move up and down, change direction and speed, and ripple out as the aircraft faces irregular motion. While turbulence is not always concerning, it is definitely an atmospheric condition that pilots strive to avoid due to the discomfort it brings to personnel and passengers, as well as the potential risks it can bring if conditions are very poor. As aircraft are specifically designed to create lift through their individual interactions with atmospheric air, they may vary in their performance during turbulent conditions based on their airframe, flight systems, and other factors.
Although tungsten inert gas (TIG) welding is commonly practiced for pipeline and pipe welding, it can be used among various industries to provide welds made from specialized materials. As fillers are not necessary for TIG welds, the process works by creating a welding arc formed between a non-consumable tungsten electrode and the component being welded. Suitable for manual welding, mechanized welding, and welding robot applications, a TIG welder must consist of the following: a power source, grounding cable, welding torch, and a shield gas tank or gas network interface. As TIG welding requires a skilled hand, we will be discussing the proper technique required for TIG welding, and its applications among the aviation industry.
