Variable stator vane · 10 cm

NEU

10 cm · bearing eye with collar · bright display side

Item no. 040-621-000

♡Saving this!

A variable stator vane of 10 centimetres — the size that sits well in the hand. The head carries an eye with a pronounced collar, and the display side has stayed bright.

What a variable stator vane is

Inside a jet engine's compressor, rotating and stationary blade rows alternate. The stationary ones — the stator vanes — straighten the air for the next stage. Some of them are adjustable: they sit in bearings and are turned together by a ring, so the compressor works as cleanly at idle as it does at full power. That is why this piece has an eye with a bore at its head, where the lever engages, and a spigot on the reverse that runs in the casing.

Provenance — honestly

Which engine this came from is not known. There are no papers with it, and apart from its shape nothing identifies the type. The material cannot be named without testing either: compressor blades use titanium, steel or a nickel alloy depending on the stage. What is certain is in the key facts — the rest stays open.
