Olympus Gas Turbine Engine Test... LOUD

High power test of Rolls Royce Olympus industrial gas turbine engine # 60 at S&S Turbines test cell in Fort St John, BC. Normally fuelled by natural gas, here we test it on gaseous propane. This hydraulically started engine produces over 40 thousand Hp, and is used to provide the power to turn an electrical generator in an overseas power station.

I don't get the power output they use for jet-engines......

40.000 hp is ALLOT. I work on a tugboat with 5500hp, and i bet it can hold back several of these jet engines just by pulling power (or thrust in case of a jetengine).... So how can this be 40.000hp? Or are the hp of a jet-engine different then diesel hp's? :)

@BelgianEvo Thrust calculations, whether for aircraft or tugboats, is always hard to get a feel for. The power of this engine in service is easily measured, because it generates electricity.

Your tug probably pulls with about 50,000 lbs or so. An airborne Olympus has about 35,000lbs of thrust, but is moving at 500 mph or so...

An Olympus in a large tugboat, geared for a similar top speed as yours would pull like a 40,000 hp tugboat.

@AgentJayZ : The tug pulls 50.000kg or 110.000lbs (calculated online because we don't use LBS here :-) I'm sure if you mount 3 of those turbines on the back of the tug and you put them in forward thrust, that the tug will still be able to go astern :-) It's indeed hard to get that you can get 40.000hp from an engine as small as that. The engines in the tug weigh about 25tonnes each..... You can see them on some of my movies :)

@BelgianEvo Ah, you need to take a look at my latest video about power turbines. For a jet powered tug, to use the engines in their air-thrust configuration would be weak, because the closer the jet stream velocity is to the vehicle velocity, the higher the efficiency gets.

So we don't use thrust at all, but a power turbine to get about 35,000 or more Hp out of the exhaust and into a turning shaft. Maybe then a gearbox and then a huge, slow turning prop, and now our boat can really pull.

@BelgianEvo Some of the Royal Navy aircraft carriers, which are smaller than the US ones use two marine Olympus engines, and they can really move.

So there's no mechanical power take-off? It's the hot exhaust gas itself turning the generator (when it's installed wherever it's going, that is)? Just curious, as I always imagined some kind of geared PTO on these aero-derivative gas turbines to power the electric generator.

thanks, btw, very cool & interesting video!

[AgentJayZ]

@HollywdPatGB Yes... The engine's HP turbine is spinning at around 8,000 and its LP turbine is running at around 4,000. The resulting exhaust is sent through a separate piece of equipment called a power turbine which turns a shaft, and the electrical generator or other load is attached to that shaft.

[BelgianEvo]

@AgentJayZ : And yeah, the tug is only moving at aprox 15mph instead of 500mph :-) But it also hs allot of weight/water to move out of the way :) It weighs 1212542lbs or 550tonnes

The Marine Olympus is still repaired in the UK by Rolls-Royce. There it is tested indoors an ran on a type of diesel

they seem to be used in many applications from fighters, EE lightning i think, the mighty Vulcan (series 202s) to concorde and i know royal navy ships also use them and now ive learnt they are also used in power stations.. a classic old engine..
