The Importance of Precision in Aircraft Parts

Precise CNC (computer numerical control) machining is critical in ensuring that plastic aircraft parts are durable, reliable, and lightweight. Whether its humidity, corrosion, rapid temperature and pressure changes, or other, aircraft are constantly subjected to harsh environments. As such, their parts must be up for a challenge. Precision machining is critical for all aircraft parts, but some need it more than others. For an aircraft to be in top shape, all parts must be functioning as intended. A single flawed or damaged part can affect the entire system. In this blog, we will discuss the six areas where precision is most important: the engine, avionics, sensors, airframe, connectors, and seating.

Engine

The engine is the heart of an aircraft, supplying the mechanical power that allows it to move and fly. If any part of the engine fails, the plane can experience a sudden loss of power or a complete mechanical breakdown. High-end, precisely machine plastics offer high wear resistance and low friction. This gives them a long, reliable lifespan and the ability to run dry if lubrication fails, further adding to its safety.

Avionics

The aircraft avionics system, including communications, navigation, as well as the display and management of multiple other systems, is the ‘brain’ of the aircraft. Avionics systems provide vital information to the pilots, meaning their reliability is critical. Military grade plastics are used to protect these systems from heat, corrosion, and electromagnetic interference.

Sensors

Sensors could be thought of as the central nervous system of an aircraft. They consist of a series of receptors that gather critical information related to the condition of the plane and the outside environment and then relay that data to the brain. Without accurate information, pilots would be flying blind. Thanks to precision machined plastic parts, sensors are able to endure harsh conditions and military applications.

Airframe

Like a skeleton of sorts, the airframe is critical in supporting the aircraft. As it supports many components and assemblies, the airframe must be strong. However, it must also be lightweight. High-end plastics offer high tensile and flexural strength comparable to metal but at a much lower weight. This reduced weight provides benefits such as increased speed and improved fuel consumption.

Connectors

Connectors have the pivotal task of keeping critical mechanical and electrical components together. These parts must be flexible and still durable enough to withstand environmental and mechanical stresses. Military-grade plastics are resistant to rust and corrosion while being able to withstand rapid changes in temperature and air pressure without warping.

Seating

Aircraft seating plays a larger role in safety than you might expect. For example, during turbulence or a rough landing, a well-designed seat will be able to absorb more of the impact energy, potentially protecting the passenger from a head injury or similar. As such, seating parts receive as much care and precision as those found in other critical areas.

Precision plastics are in use throughout aircraft where they play a vital role in its safety and reliability.
