Jet Power : VERY LOUD!!

Rolls Royce Olympus Turbojet being throttled up from idle to all the fuel we can give it.

We made 26,000 Hp on this run.

The engine is rated at 40,000 plus, but our fuel system can not feed it propane fast enough to make that.

This was a successful test.

The video is long and possibly uninteresting to some, but a very gradual throttle-up is typical of industrial engines. I have had a few requests for a full, unedited spool-up, and here it is.

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.

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

[AgentJayZ]

@ROCKSOLID19 Air tank... see answer just below.

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

[AgentJayZ]

@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.

Kind of funny seeing that huge engine powered by such a small gas cylinder. Nice video.

[AgentJayZ]

@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.

use it as a hairdryer

Now if only you can post one with run up from idle with an afterburner =D

[DrMario2007baka]

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.)

[ROCKSOLID19]

@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.
