What Are the Airframe Structural Components of an Aircraft?
Aircraft are vehicles capable of sustaining flight in the air, often coming in diverse forms such as fixed-wing aircraft, rotary-wing aircraft, gliders, and other types. The fixed-wing aircraft is the most popular of all, regularly used for personal travel, business, shipping, and other applications. While coming in a number of shapes and sizes, fixed-wing aircraft may share some similar structural components with one another, such as those on the airframe. As the mechanical structure of the aircraft, the airframe is the section of the vehicle that will typically contain the fuselage, undercarriage, empennage, and wings, all of which are crucial to flight. In this blog, we will provide a brief overview of the primary airframe structural components, helping you better understand how they function together to make a fixed-wing aircraft what it is.
Fuselage
The aircraft fuselage may be considered the body of the vehicle, consisting of a hollow tube that most other structures attach to. The hollow design of the fuselage reduces the overall weight of the vehicle, though also permits the internal construction of the cockpit, passenger cabin, and cargo section for the means of transporting individuals, baggage, goods, and more. Similar to many other airframe structural components, the fuselage may vary in shape to cater towards different applications. Generally, smaller and more slender designs are beneficial for high speed aircraft, while wide fuselages are beneficial for airliners and transport aircraft.
Undercarriage
The undercarriage of a fixed-wing aircraft typically comes in the form of landing gear, that of which is used for takeoff, landing, and taxi operations. Landing gear may come in the form of wheels and brake systems, skids, or floats, though wheels and brakes are the most commonly used. Landing gear may be fixed or retractable, the latter allowing for drag to be reduced as objects are removed from the airstream during flight. When landing on surfaces such as snow, ice, and water, skis and floats can be a very beneficial addition to fixed-wing aircraft that further diversify their use.
Empennage
The empennage is commonly referred to as the tail or tail assembly, consisting of the rear structures and airframe parts. The empennage is crucial for flight as it provides the aircraft stability, due in part to the vertical and horizontal stabilizing surfaces that extend upwards and to the sides. The empennage will also often feature a number of flight control surfaces for adjusting flight attitude, common examples being the rudder and elevator. The tail may vary in its construction depending on the aircraft to cater towards different applications, some being designed for higher speeds while others may be for increased stability.
Wings
The wing structures of aircraft are paramount to their standard operations, serving as a fin that produces lift when moving through a fluid. Wings are specifically designed for aerodynamic efficiency, often taking advantage of cross-sectional shapes and flight control surfaces in order to optimize angles of attack, airflow, lift-to-drag ratios, and much more. Just like many other airframe parts, wings too may vary greatly depending upon the intended application of an aircraft.
While such structures encompass the primary airframe structural components of an aircraft, there are also many other systems, parts, and constructions that numerous fixed-wing aircraft types may share with one another.
