Irkut Corporation, part of United Aircraft Corporation (UAC), delivered a test metal cylindrical fuselage section of MS-21 aircraft to Central Aerohydrodynamic Institute (TsAGI). The section will be used for carrying out destructive and survivability testing. The section was manufactured by Irkutsk Aviation Plant (IAP) – the division of Irkut Corporation, in accordance with the working construction documentation elaborated by the specialists of IAP and Yakovlev design bureau (part of Irkut Corporation), said in the joint statement of Irkut and TsAGI.
"A number of advanced technologies have been utilized during production of the section. These technologies will be used for production of test and serial aircraft. The section was delivered to Zhukovsky by An-124 Ruslan aircraft. Due to large dimensions of the section it was transported with some elements removed. The specialists of IAP and TsAGI will assembly the section and carry out the pressure leakage testing and pressurization. After that the scientists and specialists of TsAGI will start the destructive and survivability testing. The section will be mounted on a test rig intended for simulating the loads on all flight stages and recording a lot of parameters characterizing the behavior of the section and its elements", - said in the statement.
The purpose of these tests is experimental verification of the effectiveness of implemented design and technology solutions ensuring the design service life of the type design of MS-21 airframe. The testing of test cylindrical fuselage section is just a part of major efforts made in the network of this project. At present IAP is manufacturing a lot of test specimen including several types of fuselage panels, lateral and longitudinal joints, compartments for bird strike tests, etc. The enterprise is going to launch the production of four test aircraft in the nearest future: three of them will be used for flight testing and one more – for static testing».
The president of Irkut Corporation, Oleg Demchenko, noted: «The development of MS-21 aircraft has entered the manufacturing and testing stage».
CEO of TsAGI, Boris Aleshin, said: «The studies of this section will be carried out by specialists of Central Aerohydrodynamic Institute over the next two years. The airframe of MS-21 will perform about 100 thousand simulated flights during this period of time. TsAGI has a unique test equipment, which allows verifying the implemented design and technology solutions».
