A threaded insert, or threaded bushing, is a fastener component that may be installed in the surface of a component for the means of establishing a threaded hole. While threaded inserts may commonly be used for threaded hole repair, they may also increase the durability of softer materials, enable holes to be established in thin materials, avoid machining requirements, or be used to shift between unified and metric threads. In order to optimally install such components, a tool known as a threaded insert riveter is commonly used.

While there are various aircraft that may be unpressurized, the majority of commercial airliners and business aircraft will utilize a pressurization system for the benefit of passengers and crew members. At the high altitudes that many aircraft operate at, the presence of low air pressure can result in insufficient oxygen density that is hazardous to individuals. While an oxygen tank may be used to combat this, such solutions are not efficient for aircraft in which many individuals are aboard. As such, the pressurization control system is implemented for numerous aircraft in order to protect all individuals from hypoxia.

For aircraft to achieve heavier-than-air flight and provide the benefits of rapid global travel, they harness the forces of aerodynamics. By manipulating airflow with various structures and surfaces, a sufficient amount of lift can be created under the wings to allow the aircraft to ascend and glide. With flight control surfaces known as flaps, pilots can further manipulate the aerodynamic forces exerted on the aircraft, allowing them to increase lift as needed. While the use of flaps may vary by aircraft, they typically allow for operations to be conducted at lower speeds and distances than would be needed without them.

In many civilian and military aircraft, having an oxygen system is critical for the safety and well-being of all on board. This is due to the extreme altitudes and conditions that aircraft often operate in where oxygen levels and temperatures can be dangerously low. To ensure the safety and comfort of all, many aircraft utilize pressurized cabins and supply oxygen in order to provide an environment that is closer to sea level. In this blog, we will discuss the various methods in which oxygen is supplied to passengers and pilots across various applications and aircraft types.
