history, experts say. increasing CFM Breakthrough innovation for sustainable engines could be one of those drivers. It is a joint venture between Safran aircraft engines of France and GE Aerospace. The project was announced by CFM in June 2021. The two companies hope to build an engine that can use sustainable energy. Aviation fuels and hydrogen reduce CO2 emissions and fuel consumption by 20 instead of increasing the diameter of the aircraft engine to increase the bypass ratio.

The saffron and GE aircraft engine focused on open propellers, unlike the old turboprops, the increased CFM has a rotor diameter of 13 Feet, the core is compact, unlike the GE 36 developed in 1988, they

use recuperators and They

will

recover all the energy wasted by exhaust heat. The engine looks like a classic contra-rotating assembly, but it is not. The second stage blades are fixed and the stators have active pitch. allowing variable control that acts as flow recovery veins, increase fan pressure ratio and control rotor loading. The turbine and rotor are connected through a set of reduction gears to build and assemble the CFM of the engine.

Three sieve weaving processes will be used to manufacture the carbon fiber composite blades the hot section will use ceramic Matrix compounds and futuristic metal alloys taking advantage of a hybrid electrical system the engine will reduce fuel consumption by 20 percent a historic leap, but What about the design of engines that currently power 200-ton aircraft? The design of each engine has to be approved before being assembled. Companies have fleets of engineers to meet the specific requirements of their contractors. This is the most expensive and longest process in building an aircraft engine. The design of the Rolls-Royce Trent xwb took the company around six years. and build the first engine the process began in 2004 when Airbus began looking for an alternative propulsion system for its a350 aircraft.

In 2006 they hired Rolls-Royce and in 2010 the first a350 with two Trent xwb took to the skies one of the jet Rolls-Royce engine assembly facilities are located in Darby in the United Kingdom. What they do inside these factories seems like rocket science, but for the workers it's just another day of work. They produce a new engine every 20 days, each costing 35 million. The entire process of building an airplane. The engine starts with a fan disc. This red and gray disc is so durable that it will hold up to all 22 blades. Each of the blades is as sharp as a chef's knife, ensuring efficient airflow.

A skilled worker fixes the heavy fan blades in place. They have been manufactured in advance. and taken to the Darby facility between each of the blades, the worker will also place analyst fillers, improve airflow to the engine and complete the fan. Most of the rear of the engine using a crane then workers slowly build the core of the engine part. Meanwhile, the fan is transported in parts to a different section where workers assemble the fan casing. This is a complex process that requires hundreds of cables and pipes to be laid outside. Workers check their electronic models before installing even a single screw.

This is happening, another team of workers completes the core, they start with the compressor and build it vertically up to the combustion chamber and turbines at the top. Workers can't waste time because the floor moves up as they build the engine once the core is complete. Assembled, it can finally be joined with the fan and fan case while the core is horizontal, a rotating arm rotates the blades to ensure the fan blades fit perfectly with the fan case behind the giant fan blades there are 68 turbine blades each generate as much energy as four cars together produce more energy than 300 cars.

It takes 20 days to complete the construction of the engine, but it cannot be delivered yet. He must undergo grueling tests inside the 58 Rolls control room. Royce exposes his engines to experimental testing Once the engine is mounted on the platform, a control room operator acts as the pilot before he can do so. All locks must be in place in the security room,

this

ensures that no one can enter the test room when the engine starts to rotate until all locks are in place the engine cannot be started each test is recorded This is to ensure that the motor meets all customer requirements.

The test cell is a building within a building. This allows the control room to remain silent during loud testing. In noisy testing, there are three main types of testing: First, Rolls-Royce has approval testing that ensures all performance criteria are met before the engine is delivered, second, they have research testing and third, they have development testing, and

third part is where all of the Exciting things happening in the fan blade shutdown test, they will blow up a fan blade to see if the blade is contained within the system. They will also perform a water congestion test where they will flood the engine with tons of water simulating a storm. also bird tests where they throw dead birds into the machine to see how it reacts.

The cold start test is where they put a giant freezer around the engine, cool it overnight, and then watch the engine start when it's frozen, such as in extreme weather conditions, after passing all the tests. After testing, the engine is ready for delivery, most engines are delivered on flatbed trailers. Sometimes, if Rolls-Royce has to deliver an engine to Hong Kong Airlines, they will load the engine onto a cargo ship, take it to Hong Kong and a trailer. will take it to the facility in case of an emergency the engine will be transported by a large transport aircraft such as the Airbus Beluga once the trailer is loaded with the engine container and delivered to the facility it is time to start assembling the engine Once the engine is complete, it is time to be assembled on the almost finished aircraft.

For example, the engines for the Airbus a350 arrive at the Toulouse assembly plant. The aircraft is placed at station 20, which is the penultimate assembly station of an Airbus aircraft. finished must go through Rolls-Royce and Airbus have developed a close collaboration over the years, so they are the ones supplying the fuel-efficient engines. This a350 will be equipped with the Trent xwb inside the plant, the engine is placed on a hydraulic crane that lifts it to its mounting point. The engine weighs 8 tons and costs 32 million dollars. Inside, almost all of the twenty thousand parts are assembled by hand.

Even a single mistake could cost the company millions of dollars. So everything must be perfect. They ensure the engine has 50,000 pounds of thrust. two mounting brackets after being completely sure that the engine has been secured in place the hydraulic transport vehicle is lowered to the ground after completing the required test the aircraft is ready to enter service according to statistics the world engine market of aircraft was valued at 87.38 billion dollars in 2022 of the entire market, North America took 38.1 billion dollars. Analysis project that in 10 years the market will reach a staggering figure of 187.26 billion dollars with an estimated year-on-year growth of 7.92 percent, that multi-billion dollar giant.

The cake is eaten by four important companies, the smallest participation is for Rolls Royce with 12 percent, then comes General Electric Aviation with 14 percent and in the number two position we have Pratt and Whitney, which have a larger participation in the market than GE and Rolls-Royce. combined with a whopping 35 percent and finally the largest producer of aircraft engines is CFM International, which produces 39 percent of all engines in the world; However, when we look at historical data, things are a little different. Pratt and Whitney have produced and equipped aircraft with 13,000 engines gaining 26 percent of the market share since Boeing Lockheed Martin Airbus and Northrop Grumman are the world's largest aircraft manufacturers.

They also order the largest number of engines from the four major aircraft engine manufacturers worldwide. Airlines often request new engines to renew their fleet. fuel-efficient propulsion systems, for example, Air India recently placed a giant order with General Electric Aviation for 40 GE NX engines, 20 GE 9x engines and to top it off, with an order for 800 jump engines, the GE9x General Electric has finally been surpassed. Rolls-Royce said its new Rolls-Royce Ultra fan is fully operational. The ultra fan measures 140 inches in diameter, meaning it is currently five percent wider than the ge9x. It can be equipped on both narrow- and wide-body aircraft and can produce. thrust between 25,000 and 110,000 pounds the only thing left to do now is complete testing and Rolls-Royce will officially dethrone GE for the world's largest aircraft engine;

That being said, General Electric still holds the throne for the most powerful jet engine. in the world they even received a Guinness World Record for making the ge9x produce 134,300 pounds of thrust. Do you think Rolls-Royce with its Ultra fan can finally dethrone GE? Goodbye for now.
