News story: Navy's new carrier receives first massive gas turbine

#1
Ministry of Defence said:
The Rolls-Royce MT30, at 36 megawatts (around 50,000 horsepower), is the world’s most powerful marine gas turbine engine. Two MT30s will be installed in each of the 2 new Queen Elizabeth Class aircraft carriers and will provide two-thirds of the 109 megawatts needed to power the 65,000-tonne ships - enough energy to power a town the size of Swindon.
The power generated will meet the carriers’ demand for energy, which includes the propulsion motors, weapons and navigation systems as well as the entire low-voltage requirements for lighting and power sockets.
The MT30s are being installed as part of a gas turbine alternator which also includes an alternator and gas turbine enclosure, weighing a total of 120 tonnes.
Tony Graham, Head of Capital Ships at the Ministry of Defence, said:
The successful achievement of this major milestone has brought the biggest grin to my face since Christmas Day.
To have successfully lifted the most powerful engine in the Royal Navy onto the biggest ship ever built for the Royal Navy using the biggest capacity gantry crane in Europe is an important event in the construction of the Queen Elizabeth.
Everyone involved should take huge pride in their contribution to this national endeavour.

The Rolls-Royce MT30 gas turbine enclosure, shrink-wrapped for protection, prior to installation on HMS Queen Elizabeth at Babcock's Rosyth shipyard in Scotland [Picture: Rolls-Royce]The installation involved the lifting of the MT30 gas turbine and associated ancillary equipment - housed in a steel package known as the gas turbine enclosure - onto the ship’s structure. With the enclosure in place, the large alternator, which is driven by the gas turbine to produce electrical power, was then hoisted into place.
Currently being built at shipyards around the country, HMS Queen Elizabeth and HMS Prince of Wales are the future flagships of the nation.
Both ships are being constructed in one of the most demanding and revolutionary shipbuilding programmes ever undertaken, with the pieces being slotted together in a specially-extended dry dock. Both ships are expected to serve for up to 50 years.

So Swindon's the new metric against-which all future news articles featuring power-outputs are to be compared.

At least give us a fighting chance. How many London buses does that compare to?

You'd be able to power 159,000 simultaneously all filled with sea-skimming supersonic golf balls, which any fule know is the ISO unit of awesomeness.

Tony Graham sounds massively easy to please and should probably take a sedative before the ship launch, in case he bursts like a big watermelon of joy.

And that insane roundabout. It's like driving into 'Robot Wars' unless you commute to work in a Merkava MBT.

What a waste of time, stating the bleeding obvious. Saying that a powered warship has a powerpack is on a par with saying that Aircraft Carriers carry aircra...

OK, fair go - it's a legitimate good news story. Good effort MoD_RSS, well done.

So why don't they install three MT30s to make them functional? :???:

Isn't there plenty of empty space on the hangar deck?

The other third will be oar power.

Swindon, derived for the Domesday entry for "Suindune", believed to be derived from the Anglo-Saxon words "swine" and "dun" meaning pig hill...........well not much has changed then!

With the price of a carrier bag these days that looks expensive!
At the bottom of the Quick Reply window, there are three options: "Post Quick Reply", "Go Advanced" and "Cancel".

With experience, you'll learn which one is the most appropriate.

When I was at the Staff College, I used to take my kids into Swindon Town Centre in order to show them what would happen to them if they failed miserably in life.

The Lancaster has been modified to drop the few remaining Barnes Wallis's Grand Slam bombs. This gives the Queen Elizabeth a unique capability to attack deeply buried targets and gives the Royal Navy a strike force that will be deeply envied by our NATO allies.
