Russian technology made it possible to obtain a monolithic cellular structure of composite PD-14 engine reverser grids for the MS-21 airliner

The United Engine Corporation (UEC, part of the Rostec State Corporation) showed the production process of elements of the thrust reverser system of serial PD-14 aircraft engines.

The methods of forming an equally strong monolithic cellular structure developed in Russia made it possible to achieve high strength of the grids. Their production is carried out by TsNIISmash.

Aerodynamic carbon fiber grids are used in the design of the PD-14. They ensure reliable operation of the engine thrust reverser system even in the event of possible damage to individual elements. This is achieved through the use of a unique Russian technology that allows you to obtain an equally strong monolithic cellular structure.

The PD-14 engine is a development for the prospective MS-21-310 medium-range Russian aircraft from the United Aircraft Corporation (UAC). The family of fifth-generation turbofan engines for prospective civil, transport and special aviation received Rosaviation certification in 2018, and later received international certification. In 2023, the production of engines began.

It is known that the PD-14 weighs 2,870 kg and has a thrust of 14 thousand kgf in take-off mode. The engine can provide a flight range of up to 5,100 km, but in the future it may grow to 7,000 km. Its specific fuel consumption in cruise mode (kg/kgf • h). According to the developers, this is 10-15% better than analogues from other manufacturers, but the specific fuel consumption figure is not specified.
