Rostekh reported that the Moscow Youth Scientific and Practical Conference "Innovation in aviation and cosmonautics-2014 ”became the venue for the presentation of heat-resistant fiberglass honeycomb core for the PD-14 engine, developed by specialists of Obninsk“ Technology ”, which is part of the RT-Chemcomposite holding.
The holding specialists have created a honeycomb filler, which will be used in the noise control panels of the PD-14 engine in the area of the gas generator. These areas can heat up to temperatures in 300 degrees Celsius. Due to the chosen combination of materials and manufacturing technology, the life of a new glass fiber substrate, which received the name SSP-7-8T, in such conditions is at least 500 hours. According to the developers, one of the key features of the heat-resistant SSP was the heat-resistant glue BC-10T and the binder SP-97K, selected as a polymer matrix. They allowed to achieve the required strength characteristics at given density values.
The new Russian-made PD-14 engine is designed for the MS-21 advanced aircraft. During its development, the most modern technologies and composite materials were used. Currently, PD-14 is certified by the Aviation Register of the Interstate Aviation Committee in accordance with the Aviation Rules of the AP-33, as well as validated by the European Aviation Safety Agency (EASA).
The presentation of the operating PD-14 was held at the 2014 Moscow International Engine Forum.
