measures 6.7 metres in diameter.
HMS Queen Elizabeth will be propelled through the sea by two bronze propellers, each 6.7 metres in diameter and weighing 33 tonnes. Made by Rolls-Royce, the propellers are manufactured from nickel aluminium bronze and feature five blades mounted on a central hub. RollsRoyce is also supplying shaft lines which will link each of the vessels’ two propellers with the power source. Each propeller will deliver around 50,000hp – the highest power Kamewa propeller ever developed by Rolls-Royce.
