The advanced PD-8 aircraft engine has successfully completed tests under conditions of intense rainfall, thereby confirming its declared performance characteristics, according to a statement published on the official Telegram channel of the state corporation Rostec.
“Our United Engine Corporation has successfully tested the newest PD-8 aircraft engine for the Superjet 100 under conditions of heavy rain,” the statement reads.
Rostec reported that at a test facility near the city of Rybinsk, specialists of UEC–Saturn simulated precipitation during takeoff, climb, and landing phases. During each test cycle, tons of water were fed into the engine through a dedicated system of collectors and spray nozzles. The PD-8 operated flawlessly and fully confirmed its specified parameters.
Such tests constitute a mandatory stage of engine certification and demonstrate the correctness of the engineering solutions implemented as well as the reliability of the product, the corporation added. Previously, the PD-8 had already undergone evaluations for crosswind performance, thrust-reverser operation, and acoustic characteristics.
The engine is manufactured using modern technologies and is composed entirely of Russian-made materials. The PD-8 is intended for use on the Superjet 100 regional aircraft and the Be-200 amphibious aircraft. Earlier, the fully import-substituted Superjet successfully passed tests verifying the protection of its engines against water ingestion.
