More Hangar Styles
Apart from the above mentioned types, hangars can also be classified into the following:
- Shade hangars
- Military hangars
Shade hangars are devoid of exterior walls and are economically built as compared to maintenance or storage hangars; whereas military hangars incorporate excellent fire safety, fortification, and hardening in addition to having the best maintenance facilities. Military hangars serve the purpose of national security and thus are valued and expensive.
Also, based on style, hangars can be classified into a number of types as follows:
A simple hangar is a steel-framed building with a grand and imposing entrance and has a length up to 60-65m. Simple hangars are meant for smaller aircrafts and have different types of portal designs to suit the needed requirements. The tied portal hangar, another type of hangar, can be stretched up to 85m, whereas multi-span and propped portals can be extended to any span. A segmental tied hangar spans up to more than 200m, whereas glove hangars are economical for their span with their doors customized on the basis of a specific aircraft while the size of the front-half of the hangar is decreased.
Hangars made out of spine truss also prove effective for short hangars; however the efficiency of truss and its stiffness decreases with the increase in span. Cantilever hangars are perfect and in demand because of potential expansion. These hangars can be as long as a kilometer with a devoted workshop zone in the backyard, which also serves as a counter-weight. Butterfly hangars are similar to cantilever hangars but they require an apron on both sides.
