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!

THANKS FOR GLOBAL WARMING EARTHQUAKES STORMS WIND AND RAIN

[AgentJayZ]

@bobodd5 Earthquakes? ... that, and the all capitals thing indicates the level of understanding posessed.

Thanks for your input...

Any issues with the mesh in front of the bell mouth causing compressor stalls at all? Must create merry hell with the airflow

[AgentJayZ]

@K1w1scot It's designed to have minimal effect. Pressure at the inlet is measured and compared to ambient, and the two are compared to get the loss caused by the safety screen. Small, but used in calculation of power generated.

[AgentJayZ]

@ShadowGKCP less than that. It's bolted to a stationary frame.

.01 mpg?

@bobodd5 stay in the dark ages fool

[Ilicium]

@AgentJayZ Thanks for the info. Always interesting to see how the engineering problems are handled.

[AgentJayZ]

@Ilicium In the industrial engines, the VSVs are run with power from a separate pump, but it is pumping the engine lube oil.

So the oil system has two pressure pumps at least, delivering oil through filters to the VSV system as well as the bearings, and several scavenge pumps returning the oil through filters to a remote reservoir

[Ilicium]

@AgentJayZ Really? Have to look. I have been wondering something. In engines like the LM2500, how do fuel/hydraulics like the VSV system work without liquid fuel pressure when running on propane?

[AgentJayZ]

@Ilicium The Olympus has a hydraulic starter. More views of it in my other olympus videos.
