By February 2020, Rolls-Royce was manufacturing the 355 cm (140 in) diameter carbon fibre fan blades in Bristol, UK, saving with the composite fan case up to 700 kg (1,500 lb) on a twinjet. [71] By March 2022, Rolls-Royce had transferred the power gearbox, tested to 64 MW (86,000 hp), from Dahlewitz to its UK site for assembly, [ 72 ]
There are two solutions to this problem: 1) Open up the cold nozzle area at low flight speeds, which moves the fan working line away from the surge. This has little effect on the position or slope of the surge line. OR 2) Make the effective surge line of the fan shallower by progressively reducing the pitch of the fan as the engine is throttled.
A new update called Ultra Street Fighter IV (ウルトラストリートファイターIV) was announced for release in early 2014 at the 2013 Evolution Championship Series. Before the release of the game, Capcom set up test locations to gather fan feedback that was taken into account for the final product. [116]

The design is intended to offer the speed and performance of a turbofan, with the fuel economy of a turboprop.
This arrangement introduces an additional gas leakage path compared to a front-fan configuration and was a problem with this engine with higher-pressure turbine gas leaking into the fan airflow. [47] An aft-fan configuration was later used for the General Electric GE36 UDF (propfan) demonstrator of the early 1980s.
