Royce Makes Milestones On Royal Navy’s Aircraft Carriers
April 14, 2010 -
Rolls Royce, the global power systems company, has completed two
significant milestones for the Royal Navy’s new aircraft carriers, Queen
Elizabeth and Prince of Wales, with completion of the first propeller
and the successful testing of the vessels’ first MT30 gas turbine.
measuring almost seven metres in diameter and weighing 33 tons, has
completed acceptance tests at the Rolls-Royce facility in
Adjustable Bolted Propeller is manufactured from nickel aluminum bronze
and features five blades mounted on a central hub – there will be two on
each of the aircraft carriers.
Rolls-Royce is also supplying shaft lines which will link each of the vessels’ two propellers with the power source. Each propeller will deliver around 50,000 horse-power – the highest power Kamewa propeller ever developed by Rolls-Royce.
The first of four
MT30s for the two 65,000 ton vessels also passed a program of stringent
tests and certification at the Rolls-Royce Marine test facility, in
part of a ‘sub-alliance’ team comprising Thales, Converteam and L-3 and
has overall responsibility for delivery of the entire power and
Richard Dingley, Rolls-Royce Director Programs - Naval said: “The delivery of these two major components is a significant achievement for everyone involved in the QE Class program. The gas turbines will, through an innovative electrical system, provide the power needed to turn the propellers and drive these huge vessels through the water at speeds of up to 25 knots.
Tony Graham, head
of Capital Ships at the Ministry of Defense, visited the
Rolls-Royce Test Integration and Support Manager and his team carried
out the MT30 test. He said: “The gas turbine performed as expected
during the tests, which simulated what you would see from the bridge of
the ship in a range of different sea conditions.
“We put the engine
through rigorous tests including what happens when the ship rapidly
demands either large amounts of power or large reductions in power due
to propulsion motor trips. The engine coped well with such extreme load
characteristics and I’m pleased to say it passed its Lloyd’s
The MT30 is the
most powerful available gas turbine in the marine market today and on
the carriers will form part of an integrated electric propulsion system
which includes the giant propellers and propeller shafts as well as
rudders, thrust bearings and low-voltage electrical systems.
