Rolls-Royce Tyne

The Rolls- Royce Tyne ( Initially designated as RB109 ) was approximately 6,000 hp ( 3259-4500 kW) the most powerful turboprop in the Western world and has now been superseded by the TP400- D6 engine for the Airbus A400M.

History

It was originally developed for the airliner Vickers Vanguard. Later it served as a drive among other things, the military transport aircraft Transall C-160 ( Tyne Mk 22) and the long-range maritime reconnaissance aircraft - Breguet Atlantic ( Tyne Mk 21). The Navy versions Rolls -Royce Tyne RM1A, RM1C RM3C and are still used as a march in drive destroyers of the Sheffield class frigates and the Broadsword class in the Royal Navy. In total, more than 1500 engines were built. As a unit price in 1997 about 2.0 to 2.5 million U.S. dollars have been given. The engine was produced from his first run in April 1955 to the nineties into the Rolls -Royce and at times under license from MTU. For the remaining operating engines MTU provides maintenance and supply of spare parts.

Technology

The single-stage high pressure turbine 121 blades made ​​of a nickel alloy drives the 9- stage high-pressure compressor blades of titanium in the first seven stages, while the 3-stage low pressure turbine, not only ( a reduction gear ) to drive the propeller, but also the six -stage low-pressure compressor. Once the turbine is running, that is, the propeller turns (unlike usual today freewheeling turbines). The length of the engine ( RTy -20 Mk 21/22) is 2.76 m and the maximum diameter of 1.4 m. An engine weighs 1129 kg and consumes 0.29 kg / kWh at maximum power.

Variants

As output, the maximum power is specified with water - methanol injection, respectively.
