MS-21 - On the Way to the Sky

19 December 2014
The Enterprise Aviastar-SP has completed the assembly of the first fin torsion box for the advanced Russian airliner MS-21. Composite components for this element of the tail unit were developed and manufactured at ORPE Technologiya. In the near future, the torsion box will be sent to TsAGI (Central AeroHydrodynamic Institute named after Prof. N.E. Zhukovsky) with the aim to be statically tested.

The use of polymer composite materials (PCM) for the manufacture of aircraft components is a characteristic feature of the unique for Russian aviation project. Within the scope of the cooperation agreement on the creation of long-distance aircraft of the 21st century, ORPE Technologiya has developed the process for the production of PCM fin and stabilizer torsion box components. A wide introduction of non personal operations is a distinctive aspect of this technology. ORPE Technologiya has developed and manufactured over 4000 of standard and similar in design prototypes and fragments of the tail unit.

Only several companies in the world can manufacture large-sized products from PCM, so the production of such components in Russia is unique. This is evidenced by the success of the 7 m fin torsion box panel (made at ORPE Technologiya for MS-21) demonstrated at the JEC Composite Show-2014 in Paris.

One more project of ORPE Technologiya within the framework of the cooperation agreement on the creation of the MS-21 is the development and manufacture of composite units for PD-14 engine nacelle which is supposed to be used in MS-21.
