how does a trent engine work

Full Answer

How a jet engine works step by step?

The blades spin at high speed and compress or squeeze the air. The compressed air is then sprayed with fuel and an electric spark lights the mixture. The burning gases expand and blast out through the nozzle, at the back of the engine. As the jets of gas shoot backward, the engine and the aircraft are thrust forward.

What is the problem with Trent 1000 engines?

This made the Intermediate Pressure (IP) blades more susceptible to cracks, thereby reducing their potential lifespan. This change in environmental conditions was further compounded by a design flaw in the high pressure (HP) turbine blades.

How does a Rolls-Royce engine work?

The hot gases from the combustor are conveyed through a series of turbine stages. Each one of them gains energy from the steady flow of gas, rather like a windmill. This energy is primarily used to drive the fan and compressor via shafts. The blades have to be extensively cooled to prevent them melting.

What is a Trent 600?

The initial variant, Trent 600, was to power the McDonnell Douglas MD-11 with British Caledonian as the engine's launch customer. However, when British Airways bought British Caledonian in 1987, they cancelled the MD-11 order. With the collapse in 1991 of Air Europe in the aftermath of the 1990 Gulf War, the only other Trent-powered MD-11 customer was lost. As the MD-11 was itself suffering poor sales due to its failure to meet its performance targets, the Trent 600 was downgraded to a demonstrator programme, engine development being switched to the Trent 700 for the Airbus A330.

How much thrust does a 777 have?

How often do Trent 1000s need inspection?

In April 2018, the inspection interval for 380 Package C Trent 1000s was reduced from every 200 flights to every 80 to address durability problems, as the EASA should be followed by the US FAA, reducing ETOPS from 330 to 140 minutes and impacting trans- Pacific flights. On 17 April the US FAA confirmed this ETOPS reduction. On 19 April, the EASA issued an Airworthiness Directive stating "occurrences were reported on RR Trent 1000 ‘Pack C’ engines, where some IPC Rotor 1 and Rotor 2 blades were found cracked. This condition, if not detected and corrected, could lead to in-flight blade release, possibly resulting in reduced control of the aeroplane." EASA inspection rates are increased but ETOPS are maintained.

How many nozzles does a Trent 1000 have?

The Trent 1000 is a high bypass turbofan with three independent, coaxial shafts and a single annular combustor with 18 spray nozzles. The Low Pressure shaft with a swept-bladed, 2.85 m (9 ft 4 in) fan is powered by six axial turbines . The Intermediate Pressure spool with 8 axial compressors is turned by a single turbine stage. The six-stage High Pressure Compressor is driven by a single turbine stage, turning in the opposite direction of the two others shafts. The engine is controlled by an EEC.

When was the Trent 1000 made?

The first run of the Trent 1000 was on 14 February 2006. On 18 June 2007, it made its first flight from TSTC Waco Airport in Texas, on Rolls-Royce's flying testbed, a modified Boeing 747-200. On 7 July 2007, aircraft lessor International Lease Finance Corporation placed an order worth $1.3 billion at list prices for Trent 1000s to power 40 of the 787s which it has on order, $16.25 m per engine. The engine received joint certification from the FAA and EASA on 7 August 2007, or 7/8/7 in Europe.

How much thrust can a Genx engine produce?

Therefore, if an engine could produce 2.2 pounds of thrust, it could accelerate a one-kilogram block at 9.8m/s². At the maximum thrust which the GEnx can generate, it can accelerate a 76,100-pound block at the same rate. Pretty powerful indeed.

What is a Genx engine?

The GEnx is a high-bypass engine, meaning that most of the air drawn in isn’t actually used in combustion to generate thrust. Instead, the engine design creates a duct whereby 90% of the air flows around the outside of the engine core.

What engine does a 787 Dreamliner use?

The Boeing 787 Dreamliner, which I fly, comes with the option of either the General Electric GEnx or the Rolls-Royce Trent 1000. The engine on a 787 Dreamliner. With 53% of all 787 orders, the GEnx is the most popular choice with the Trent 1000 accounting for 33%. The remaining 14% of orders remain undecided.

How much does a Genx engine weigh?

The GEnx is a massive bit of kit. The front rotating fan measures 9.2 ft across. The whole engine weighs 13,200 lb and can produce 76,100 pounds of thrust (a pound of thrust is equal to a force able to accelerate one pound of material 32 feet per second per second.)

What is the energy used in the combustion chamber?

Here, the energy is used to create thrust and also to keep the various stages of the engine in front of it running.

What is the final stage of the 787 engine?

The final stage of this process is where innovative technology has reduced the noise of the 787 engines compared to other types. The edges of the engine casing seem to have had pieces cut out of them, creating a circle of rounded teeth. This is called scalloping.

Which engine is better, GEnx or CF6?

The GEnx provides 15% more fuel efficiency and 15% less CO2 than the General Electric CF6 engine, which powered the 747-400. It’s also an airline favorite for its maintenance performance, using 30% fewer parts and going 20% longer before needing major engineering work.
