context_page_description: The Rolls-Royce Trent 800 is a high-bypass turbofan produced by Rolls-Royce plc, one of the engine options for the early Boeing 777 variants.
  Launched in September 1991, it first ran in September 1993, was granted EASA certification on 27 January 1995, and entered service in 1996.
  It reached a 40% market share, ahead of the competing PW4000 and GE90, and the last Trent-powered 777 was delivered in 2010.
  The Trent 800 has the Trent family three shaft architecture, with a 280 cm fan.
  With a 6.4:1 bypass ratio and an overall pressure ratio reaching 40.7:1, it generates up to 413.4 kN of thrust.
context_section_description: The Trent 800 is an axial flow, high bypass turbofan with three coaxial shafts.
  The fan is driven by a 5-stage axial LP turbine (3300 rpm), the 8-stage IP compressor (7000 rpm) and the 6-stage HP compressor (10611 rpm) are each powered by a single stage turbine.
  It has an annular combustor with 24 fuel nozzles and is controlled by an EEC.
  The engine has a 6.4:1 bypass ratio in cruise and an overall pressure ratio of 33.9 to 40.7:1 at sea level, for a 340.6-413.4 kN (76,580-92,940 lbf) take-off thrust.
  The 280 cm (110 in) fan has 26 diffusion bonded, wide chord titanium fan blades.
  Rolls-Royce claims it is the lightest Boeing 777 engine, citing a 8,000 lb (3.6 t) weight saving over the GE90 and 5,400–6,500 lb (2.4–2.9 t) over the PW4000. The Trent 800 weighs 6.078 t (13,400 lb) dry, while the GE90 is 17,400 lb (7.89 t), and the PW4000 is 16,260 lb (7.38 t).
  Japanese KHI and Marubeni Corporation are risk and revenue sharing partners on the Trent 800.
