A Summary of the Aircraft Empennage
The main components of an aircraft are the fuselage, wings, power plant, landing gear, and empennage, each of which takes on an important role in the construction and operation of the aircraft. The fuselage is the main body of an aircraft, where the cabin, crew, and passengers reside. The wings, also known as foils, generate the lifting force necessary for flight. The power plant is made up by the engines and propellers, and the landing gear, which comprises wheels and shock absorbers, is critical for safe landing. The final main component, the empennage, is the tail assembly at the rear of an aircraft. This blog will cover in detail the parts and functions of the empennage.
There are several types of empennages, all consisting of several parts. The empennage is not a single piece, but rather an assembly that comprises many parts. Some of the most common components of the empennage include the tailfin, tailplane, and the rear end. Together, these parts are referred to as the empennage. It serves many purposes, chief of which is to stabilize the airplane during flight. It provides a surface on which the aircraft stabilizers can be mounted. On most commercial airplanes, there are multiple stabilizers, including a pair of horizontal stabilizers and a single vertical stabilizer. All these parts are found on the empennage. During flight, these stabilizers are used to fly the aircraft in a more straight line by reducing side-to-side movement.
The structure of the stabilizers is very similar to that of the wings. Like a wing, the stabilizers feature spars, ribs, stringers, and skin. They perform the same functions of shaping and supporting the stabilizer as well as transferring stresses. Bending, torsion, and shear loads created by air during flight pass from one structural member to another. Each member absorbs some of the stress and passes the remainder on to the others. Ultimately, the spar transmits any overloads to the fuselage. A horizontal stabilizer is built the same way.
Apart from stabilization, the empennage also provides directional control. Using control systems like stabilizers attached to the empennage, pilots can quickly and easily change the direction of the aircraft. Without an empennage, changing direction would be a far more difficult undertaking. The empennage is critical to aircraft when maintaining stability during flight. Stabilizers cannot be mounted on the front end or middle section of the fuselage. Instead, they must be mounted on the empennage.
Though rare, certain aircraft do not have a tail. Examples include the Concorde, AVRO Arrow, and the Space Shuttle. These are all supersonic aircraft. As supersonic flight becomes more common, tailless aircraft will also become more common. Canard aircraft are another type of aircraft that do not have a standard empennage. Instead, these feature elevators and a horizontal stabilizer ahead of the main aircraft wing. Canard aircraft have all the same controls as a conventional aircraft, just in different places.
