Russia dumps tons of water on the PD-8 engine of the Superjet-100 and confirms full reliability
The United Engine Corporation (ODK), part of the Russian state conglomerate Rostec, has confirmed the successful testing of the PD-8 aircraft engine under heavy-rain conditions, a crucial step in the certification process of the powerplant that will equip the Superjet-100 regional jet.

The tests were conducted by ODK-Saturn at an open-air test stand in the Yaroslavl region, where engineers simulated massive volumes of water entering the engine during critical phases of flight, such as takeoff, climb, and approach for landing.
Three complete evaluation cycles
The tests were divided into three cycles involving different engine operating regimes—from minimum power to maximum takeoff thrust—including rapid accelerations and decelerations to verify operational stability.
Special system to simulate heavy rain
The test facility includes a structure equipped with four collectors and multiple nozzles capable of spraying water in precisely calibrated droplets. The system is supplied by a high-pressure reservoir capable of launching several tons of water onto the running engine.
According to ODK’s deputy sales director, Fedor Mironov, these trials are essential to proving the powerplant’s reliability under extreme weather conditions:
“Tests simulate the ingestion of rain into the engine and are an important stage for PD-8 certification. We created special equipment that allows us to spray several tons of water. The engine once again confirmed the correctness of the applied design solutions. It operated with no remarks and met all declared specifications.”
He adds that testing will continue both for certification and for the engine’s integration into the Superjet-100, in cooperation with UAC, also part of Rostec.
Testing background
Before this phase, the PD-8 had already undergone several engineering trials, including:
- acoustic tests,
- operation under crosswind conditions,
- evaluation of the thrust reverser, which uses a grid-type system with electric actuation inspired by the certified and in-production PD-14 engine.
The PD-8 is considered a strategic component for reducing Russia’s reliance on imported parts in civil aviation.
