The company Buildair, a spin-off arising from Cimne research center linked to CPU Yet the Generalitat, has successfully installed in the Jeddah airport (Saudi Arabia) on inflatable hangar largest in the world - with tubes of 8 meters in diameter and 75 meters of interior light and length of 100 meters. The client is the aeronautical company Saudí Aeronautical Engineering Industries (SAEI).
The hangar has been projected and manufactured by Buildair in its factory in Sant Feliu de Llobregat in a record time of five months and in June it was transported to Arabia for its installation. The total cost of the project amounts to 8.1 million euros, which includes the cost of the inflatable structure for a value of 2.9 million, the interior facilities of the hangar for another three million and the clamping slab of 2.2 million of euros. The hangar is made of PVC coated fiber that is anchored to the ground. It is the largest inflatable structure in the world and an engineering challenge, with 38.5 meters high, 92 meters wide and 92.5 meters long, and equipped with an air conditioning system. The project has been carried out at the request of Saudi Airlines for the maintenance of the fleet.
Buildair beats its own record, which boasted the H54 hangar of Airbus at the Getafe Air Base built in 2013.
The company born from the technology center Cimne has built the structure in Sant Feliu de Llobregat
The hangar H75-SAEI has been installed in the MRO area of Jeddah airport and has been designed to house large aircraft such as an Airbus 300 or a Boeing 777. It is designed as a membrane system with inflatable tubes, which are the relevant element of installation. The PVC membranes are filled with air by means of a blower, which works with a motor system and constantly provides the stiffness required for the structure. The enclosure is designed to maintain the precise comfort and safety conditions inside. Includes two sets of front and two other side curtains. The front enclosure is built on mobile trolleys, which allows the opening and closing operation.
The advantages of this type of inflatable facilities for the maintenance of aircraft is the speed -with delivery times of one to six months- and the low cost. It is not necessary to request building permits as they are considered equipment and not buildings. They are completely removable and transportable in normal containers.
Buildair, is a spin-off of the International Center for Numerical Methods in Engineering (Cimne) created in 1987 by the Generalitat and the Polytechnic University of Catalonia. It was created in 2001 by researchers from the UPC and the Cimne and has since developed technology for calculating structures under wind and snow loads for Buildair.
