A study was conducted at Perm National Research Polytechnic University (PNRPU) on the impact of volcanic ash clouds on the operation of aircraft engines. This was reported in the press service of the university.
When particles hit the surface of the nozzle vanes of the turbine, they cool and crystallize. This creates deposits that reduce the space between the blades. Experts have found that the accumulation of volcanic soot particles on the aircraft nozzle can lead to engine failure.
Scientists have for the first time numerically estimated the volumes of high-temperature zones in the engine of aircraft. It is in this area that ash particles turn into a liquid phase and pose a safety threat.
Calculations have shown that lowering the thrust of aircraft engines to low throttle in a volcanic cloud slows down the formation of deposits on the nozzle, while attempting to gain altitude increases the melting area of ash by 81%. In this regard, pilots are advised not to try to rise above the emission zone, but to leave it at low thrust with a 180-degree turn.
Earlier www1.ru reported that Russia will complete the development of a wide-body aircraft with PD-35 engines after 2030.
