This is our old test cell and fuel system, so it was a 6,000L tank of liquid propane. The Olympus ate up most of it in about 30 min, but only a part of the test run is at full power. There is quite some time spent at idle power.
O_____O That gotta be one of the most powerful engines... Reading AgentJay's description somewhere here, of the fuel tank to this jet engine really reminded me why Concorde no longer fly today: IT SUCKS UP LOT OF FUEL....
That really prompted me to ask a question: How long did 10,000 Liter of LPG last on this run? (I know it won't last too long with afterburner, though.)
@AgentJayZ Thanks. I did not notice that answer was already answered. From afar, I was convinced it was a gas cylinder. I know not that putting an actual one there with gas is obviously stupid. Jet turbine engineering is an understated masterpiece. Im on an electrical engineering course myself and normally see hydro and steam turbines.
@bamaslamma1003 There are various versions that were used to fly. One of the closest relatives to this engine was the Olympus used in the Avro Vulcan bomber.
I believe they were rated at 35,000lbs thrust each.
The Olympus engines used in the Concorde were much uprated, and were also fitted with afterburners. They were called the 593, and I have never seen one.
So this is running on propane. Did you have to do any modifications? Was it designed for propane or is there no functional difference between feeding it propane vs. kerosene?
Aftreburners are not used in industrial applications. The power turbine is designed for the gas flow of the engine., and can't be adjusted on the fly to the increased volume of hotter gases created by reheat.
If more power is needed, either more engines are used, or a bigger engine.
So, no, there is no chance of an Olympus afterburner test.
Marine units on military ships are, but this is an engine that will be running in an electrical generating station. Also, this is the first run of an engine that was completely disassembled and overhauled.
The normal caution of a test run is to take it easy initially.

Is that a gas cylinder next to the engine at 0:26 onwards?????

On an aircraft, how much thrust does one of those engines make?

Kind of funny seeing that huge engine powered by such a small gas cylinder. Nice video.
bamaslamma1003 1 year ago
@bamaslamma1003 ...Did you see that? That is funny.
The engine is fuelled by the large blue hose which leads to a 10,000L tank of liquid propane.
The small white container is a propane bottle, but it is filled with air at 120 psi, which is used to hold open our Emergency Shut Down valve.
The bottle is always in the same position because it has to be close, and it has top priority amongst all our equipment.
We've never had to use it.

Are you using the cameras audio system to capture the sound?....Just curious.
pawfan 2 years ago
Yes. I would like to be able to record the sound without as much distortion.
The camera is wrapped in foam and taped up, and even at 50 yards away the exhaust noise is frying the microphone.

The only thing different about this engine and one that uses "jet fuel" is the size of the holes in the fuel nozzles. Bigger for gaseous fuel.
Many industrial engines have "dual fuel" nozzles, which is a bit of a misnomer.
The dual means liquid and gaseous.
A liquid fuel nozzle can handle jet fuel, diesel, kerosene, gasoline, alcohol, olive oil, or any flammable liquid.
A gaseous nozzle can handle propane, butane, methane, natural gas, hydrogen.

Now if only you can post one with run up from idle with an afterburner =D
zero10iz 3 years ago
This is an Olympus, so an afterburner test is a near zero possibility.
BUT
If you want to see a start - to AB test... all you need to do is look at another of my videos: "Fighter jet engine afterburner test".
It's all there, in supersonic glory.
As always... please read the "more info" section!

No chance of finding the reheat unit of a 593 to bolt onto it then? ;-)

I wish there was, though.

They can, but are never run that way in service.
Marine units on military ships are, but this is an engine that will be running in an electrical generating station. Also, this is the first run of an engine that was completely disassembled and overhauled.

Can industrial engines do a quick throttle up or are they just incapable of it?
