Rolls Royce Olympus

Test run: Rolls Royce Olympus at S&S Turbines open-air test cell.
One of the largest turbojet engines, about 40 thousand Hp in the industrial version shown here.

Looking in the front at startup, you can clearly see the freshly cleaned elements of the low-pressure compressor:

First are the struts, which hold the front main bearing firmly in place.
The LP rotating shaft is supported by this bearing.

Second, you see the copper-colored inlet guide vanes. On many engines these are able to move, but in the Olympus they are fixed.


Then the blades of the first stage of the turning compressor shaft.
They are made of solid titanium alloy, and it took 2 days to hand polish them.

Next, the first stage of compression is made complete by stator vanes, which are directly behind the spinning blades.

The Olympus is the engine used in the Concorde, and the Vulcan Bomber. Both used four Olympus engines, each with an afterburner. This engine does not have an afterburner.
This engine is used to generate electricity. A lot of it!
