The nacelle of the new Russian PD-14 aircraft engine for the MC-21 aircraft has been equipped with an electric sliding reverser. This was reported by the press service of the United Engine Corporation (UEC).
When creating the PD-14, the designers of "UEC-Aviadvigatel" (part of UEC) abandoned the conventional clamshell-type reversing device and were the first in Russia to use an electric drive.
The nacelle components and reversing device grilles are made of domestic polymer composite materials. This approach significantly reduced the weight of the power plant and increased the rigidity of the nacelle components.
The nacelle is used to install the engine on the wing of an aircraft and consists of a fairing, housing, doors, components, and a reversing device that provides braking during landing.
Earlier, www1.ru reported that almost 4 billion rubles will be allocated in Russia for the refinement of the Ansat helicopter.
