Superjet SJ-100 Tests New Mode of PD-8 Aircraft Engines at Minimum Speed

Aircraft Reached Maximum Angles of Attack in Flight

The first Russian Superjet 100 aircraft, which took to the skies on domestic PD-8 engines, tested a new power plant mode during its latest flight. This was reported by the press service of the United Aircraft Corporation (UAC, part of Rostec).

In flight, the Superjet reached maximum angles of attack — the angle between the wing chord and the oncoming airflow vector — 25 degrees and a minimum speed of 183.348 km/h or 99 knots.
