Fine piece of machinery.
Here’s an interesting footage filmed form inside a Russian Tu-95 Bear bomber like the ones that skirt northern Europe’s airspaces every now and then.
Although it does not show anything special about the plane, the rare video lets you have a close look at the eight-bladed coaxial contra-rotating propellers Kuznetsov NK-12 engines of the Tu-95.
Indeed, the only propeller-powered strategic bomber still in operational use today, features the typical two propellers, arranged one behind the other, which increase efficiency and performance.
An in-flight, engine shutdown and restart cycle can be seen in the clip.
H/T to @Missilito for the heads-up
