Portable clear span hangar for global maintenance

Over 8,000 Russian-made helicopters are currently operating in more than 100 countries worldwide. As a leading player in the industry, Russian Helicopters holding companies have produced 42% of the global medium-heavy transport helicopter fleet. Their legendary Mi-17 helicopters are what gained them the attention of the global market.

Russian Helicopters have made it their mission to increase their overall customer satisfaction by offering services at their customers' locations. In the past, the helicopters were transported to MRO facilities in Russia. Transporting choppers was not only an expensive and slow exercise but had negative consequences on the environment.

With over 8000 Mi-8 and Mi-17 helicopters across five continents in the market, the efforts to move their maintenance hangar needed to be the least possible. However, the size of the helicopters made this challenge hard to overcome.

Challenges

The dimensions of Mi-8 and Mi-17 models with blades span to 23 meters in diameter and 6 meters in height. Transportation of the aircraft requires chartering an airplane or 60 days at sea each way. Such service model was not efficient for Russian Helicopters nor their customers.

Though the helicopters are usually parked in the open air, the maintenance and service have to take place in the closed hangar. Once the aircraft is stripped, it needs to be sheltered from the external environment to ensure that no dust or debris penetrates the interior. A dismantled helicopter and its components are prone to water drops that cause erosion and electrical short circuit.

Helicopter maintenance facilities house valuable equipment such as testers, spare parts, instruments, cranes, ground power units, chemicals, greases, oils.

Delivered materials and accessories

Russian Helicopters in the early stages of their business initiative ordered a smaller hangar (800 m², 17×7 meter gates) to facilitate the maintenance of their Mi-8 and Mi-17 helicopters.

Proving great success, Russian Helicopters acquired a bigger hangar (1250 m², gates 17×7 meters) to service their Ka-52 helicopters.

Both hangars accommodate double axes overhead cranes with the lifting capacity of 2 tons on inflatable frames. There are no support columns within the structure.

The delivery kit included energy-efficient lighting solution, gate automation, autonomous power back-up system and a telematic system.

Results and execution

Integration of a double axes overhead crane is a one of a kind engineering solution that proves once more, how rigid Aviatech Inflatable frame structures are. Aviatech team designed, tested and produced the hangar in 103 days.

Two years later, the second, almost double size facility was ordered. It was delivered in a much shorter time frame.

In three years, the first hangar has already housed Mi-17 helicopter maintenance across the globe including the Middle East, South America, and the CIS countries.

“Our vision was simple. We wanted to provide excellent customer service on all of our helicopters. Traveling to customers to overhaul Mi-17 helicopters was a big change for our daily operation. Without the support of inflatable structures, this vision would not have come to reality.”
