The aircraft engine of the Russian airliner MS-21 was tested by volcanic ash. The United Engine Corporation (UEC, part of Rostec State Corporation) has tested the PD-14 engine. This is reported on the Rostec website.
Experts tested the PD-14 engine gas generator under the influence of volcanic ash. To do this, at the stand of the Central Institute of Aviation Engine Building (CIAM) named after P.I. Baranov, flight was simulated in an aggressive environment using the ash of the Kamchatka volcano Shiveluch.
"Rostec State Corporation for the first time in the history of Russian engine building conducted tests of an aircraft engine gas generator under the influence of volcanic ash. The gas generator of the latest PD-14 engine for medium-haul airliners was successfully tested by the ash of the Kamchatka volcano Shiveluch — an hour spent in this aggressive environment practically did not lead to a change in its characteristics," said Anatoly Serdyukov, industrial director of the Rostec aviation complex.
In August, the head of the United Aircraft Corporation, Yuri Slyusar, announced the date of the start of flights of the MS-21 airliner. According to him, the aircraft will begin operating regular flights in 2022.
In July, the general designer of UEC-Aviadvigatel, Alexander Inozemtsev, named the differences between the PD-35 engine and the PD-14. He noted that the power unit differs from the PD-14 of the fifth generation in that it belongs to the 5+ generation.
