Rolls-Royce Trent is a series of aircraft turbofan dual-circuit engines ( turbofan engines ) developed by Rolls-Royce plc in the second half of the 1980s for medium and long-haul commercial passenger airliners and transport aircraft. The first commercial model, the Trent 700 was launched in 1990. It is mass-produced and used on commercial Airbus A330 , A340 airliners, as well as on Boeing 777 and 787 Dreamliner airliners. The Airbus A380 uses the Trent 900 . In 2010, Rolls-Royce plc developed new Trent XWB engine modifications for the Airbus A350 XWB family of aircraft.

Rolls-Royce Trent Series Development History
Marketers at the Rolls-Royce plc aircraft engine department decided that in order to increase their market share it was necessary to develop an engine suitable for almost all commercial airliners in operation. The only way to reduce R&D expenses for the development of new engines was the decision to design a single engine family on one structural platform. The constructive basis for the new turbofan engine family was the previously developed successful Rolls-Royce RB211 three-shaft turbofan engine design, in the design of which numerous variants of combining low, medium and high pressure turbines of various sections were possible, which gave an extremely wide range of characteristics on various modifications of one engine.
Information about the development of a new family of commercial turbofan engines was presented by Rolls-Royce plc at the Farnborough Airshow in 1988. The name of the series was taken from the name of the Trent River in the UK, previously used in the names of two models of Rolls-Royce plc aircraft engines - the world's first Trent RB.50 turboprop engine and the RB.203 Trent turbofan, the first three-shaft turbofan engine Rolls-Royce plc with a maximum thrust of 4,400 kgf, which replaced the Rolls-Royce Spey family in the 1960s. The Trent turbofan engine of the 1960s did not go into production, but was the technical predecessor of the Rolls-Royce RB211 turbofan engine , which formed the basis of the 1990s Rolls-Royce Trent series.
Design Features
Rolls-Royce Trent turbofan engine is a basic dual-circuit three-shaft turbojet engine with a mixture of internal and external circuit flows behind the turbine, with the general architecture of the design borrowed from the Rolls-Royce RB211 series of three-shaft turbofan engines developed and manufactured by Rolls-Royce plc.
The design of a turbofan engine with a three-shaft turbine allows it to be used in a wide range of modes, due to the possibility of separately setting the modes of low, medium and high pressure compressors. The large diameter inlet fan (295 cm) can significantly reduce the inlet speed, which makes it possible to limit the noise take-off performance to the level required by the technical characteristics of such large civil airliners as the Airbus A380 [1] .
