Hangar
Encyclopedia
A hangar is a closed structure to hold aircraft
Aircraft
An aircraft is a vehicle that is able to fly by gaining support from the air, or, in general, the atmosphere of a planet. An aircraft counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines.Although...

 in protective storage. Most hangars are built of metal, but other materials such as wood and concrete are also sometimes used. The word hangar comes from Middle French hanghart (“enclosure near a house”), of Germanic origin, from Frankish *haimgard (“fence around a group of houses”), from *haim (“home, village, hamlet”) + *gard (“yard”)."

Hangars protect aircraft from weather
Weather
Weather is the state of the atmosphere, to the degree that it is hot or cold, wet or dry, calm or stormy, clear or cloudy. Most weather phenomena occur in the troposphere, just below the stratosphere. Weather refers, generally, to day-to-day temperature and precipitation activity, whereas climate...

 gas to provide them with sufficient buoyancy for flight, so their hangars had to provide protection from stray sparks in order to prevent the flammable gas from exploding. Hangars that held multiple craft of this type were at risk from chain-reaction explosions. For this reason, most hangars for hydrogen-based airships were sized to house only one or two such craft.

Structures and sizes

Hangars need special structures to be built. The width of the doors have to be large, and this enables the aircraft entrance.
The bigger the aircraft are to be introduced, the more complex structure is needed. According to the span of the hangar, the sizes can be classified:







Size -Span (meters)
S - Less than 30 m
M - 30 m – 60 m
L - 60 m – 90 m
XL - 90 m – 120 m
XXL - More than 120 m


The XXL hangars are built for the biggest aircraft in the world: Airbus
