Airport Hangar Sizes: Massive Structures For Aviation Giants

Airport hangars are large buildings used to store, maintain, and repair aircraft and other related equipment. They are typically constructed out of metal, wood, or concrete and come in various sizes and types, including small, medium, and large hangars, as well as T-hangars and box hangars. The size and type of hangar depend on the aircraft's dimensions and specific needs of the airport or aircraft operator. XXL hangars, for instance, are designed to accommodate the largest aircraft in the world, such as the Airbus A380 and Boeing 747.

XXL hangars for the largest aircraft

XXL hangars are designed for the largest aircraft in the world, such as the Airbus A380, Boeing 747, and Antonov 225. These hangars are the most complex to build due to their size and the need to house the largest aircraft. They are constructed of sturdy materials like metal, wood, or concrete to provide protection from the weather and direct sunlight, and to facilitate maintenance, repair, assembly, and storage of aircraft.

One example of an XXL hangar is Hangar 375, also known as "Big Texas," located on San Antonio's Kelly Air Force Base. With a massive 600,000 square feet of space, it is recognised as the largest active free-standing aircraft hangar in the world. However, not much information is available to the public due to its use in a US military installation.

Another XXL hangar is located in Brandenburg, Germany, called the Aerium Hangar. Built in the mid-1990s, it was intended to house the production and storage of the CargoLifter airship CL 160. Although the airship was never built, the hangar remains an impressive structure, spanning 851,500 square feet. Today, it has been transformed into a large resort and water park called Tropical Islands, boasting the "World's Largest Indoor Rainforest."

In addition to military installations, commercial airlines also require XXL hangars for their large aircraft. For instance, the GDC Technics hangar at Alliance Airport in Fort Worth, Texas, spans 840,000 square feet and was constructed in 1992 at a cost of over $90 million. This hangar has the capacity to hold six wide-body and four narrow-body aircraft simultaneously, including a 747-400.

Lastly, the Boeing Everett Factory in Everett, Washington, is a massive structure that serves as both a production plant and a storage facility for newly finished Boeing planes. With an astonishing 4.3 million square feet of space, it claims the title of the world's largest free-standing structure. Visitors can tour the facility and learn about its fascinating features and history.

T-hangars for individual aircraft storage

T-hangars are a common type of hangar used for general aviation purposes and individual aircraft storage. They are designed to provide separate storage for each aircraft, with each hangar bay connected to a central corridor, forming a distinctive "T" shape when viewed from above. This design allows for efficient use of space and reduces the required taxiway length compared to standard hangars.

T-hangars are typically used for single-engine or small aircraft and offer individual storage while optimising space. The nested design of T-hangars, where the tail sections are nested into the centre of the structure, reduces the overall length of the hangar, enabling the accommodation of various aircraft sizes. This versatility allows for customisation to meet specific storage requirements, such as including jet pods or clear span modifications.

Constructed primarily of metal, wood, or concrete, T-hangars provide protection from the elements and potential damage from ground contact with other aircraft ("hangar rash"). They also offer enhanced security and safety for aircraft, minimising long-term expenses. T-hangars may include features such as a steel open web truss over the door opening, supporting the door and roof structure, and ensuring smooth and safe door operation.

When considering T-hangars for individual aircraft storage, it is essential to take into account factors such as material costs, hangar dimensions, and additional fees to ensure a cost-effective decision that meets the specific needs of aircraft owners without compromising quality or security.

Box hangars for multiple aircraft

Box hangars are large, rectangular structures designed to accommodate multiple aircraft. They are commonly found at Minnesota's general aviation airports and are ideal for storing mid-sized to large aircraft, corporate jets, and helicopters. The size of box hangars provides ample space for repair equipment, tools, and even office spaces.

One of the key advantages of box hangars is their ability to hold multiple aircraft simultaneously. This makes them a popular choice for airports with a diverse range of aircraft. The large space allows for efficient aircraft movement within the hangar, which is essential for maintenance and repair work. Additionally, the rectangular shape of box hangars provides a straightforward design that optimizes the available area.

Box hangars are often heated, which is beneficial for maintaining comfortable working conditions during maintenance and repair operations. The heating system helps create a suitable environment for both personnel and aircraft, ensuring that maintenance tasks can be performed effectively, regardless of the outside temperature.

Another benefit of box hangars is their flexibility in terms of usage. While primarily designed to house aircraft, the extra space allows for the inclusion of additional facilities. For example, box hangars can accommodate storage areas for repair equipment and tools, as well as office spaces for administrative tasks. This versatility enhances the functionality of the hangar and can contribute to more efficient airport operations.

It is important to note that the design and construction of box hangars, like all hangars, are subject to specific regulations and standards. These structures must adhere to Federal Aviation Administration (FAA), local, and state building requirements, as well as design limitations and criteria set by the airport. Additionally, regular maintenance and inspections are crucial to ensure the hangar's safety and longevity, with particular attention given to cables, hazardous materials, and aeronautical usage.

Steel airship hangars

Hangars are buildings or structures designed to hold aircraft or spacecraft. They can be built from metal, wood, or concrete. Steel hangars are made from galvanized steel, which has a higher tensile strength than other construction materials, providing excellent protection for aircraft. Steel also has anti-rust and anti-corrosive properties, making it highly durable and reducing maintenance requirements.

Steel hangars offer several advantages over other materials. They can provide a column-free interior and extra-wide doors, maximizing space and ease of access for aircraft. Steel hangars are also affordable, with pre-engineered structures that are easy to transport and erect, reducing construction time and labour costs. Additionally, steel is the most abundant and recycled metal globally, keeping raw material costs reasonable.

The size of a hangar depends on the aircraft it is designed to accommodate. XXL hangars, for example, are built for the largest aircraft in the world, such as the Airbus A380, Boeing 747, and Antonov 225, and are the most complex to construct. Steel hangars can be customized to meet specific size requirements, ensuring aircraft owners can provide proper storage for their aircraft.

Medium-sized hangars used for aircraft maintenance and storage

Medium-sized hangars are commonly used for aircraft maintenance and storage. They are designed to accommodate a range of aircraft sizes, from small single-engine planes to mid-sized jets and helicopters. These hangars offer a dedicated space for maintenance, repairs, and storage, ensuring that aircraft are protected from the elements and potential damage.

The size of a medium-sized hangar can vary depending on the specific needs of the aircraft operator. It should be large enough to house the aircraft, along with any necessary equipment, tools, and personnel required for maintenance and repair work. Some medium-sized hangars may also include additional features such as office spaces, workshops, or storage areas for repair equipment.

The location of medium-sized hangars is an important consideration, as they should be easily accessible and in close proximity to essential facilities such as fuelling stations, maintenance shops, and control towers.
