Throughout the little more than one hundred years of aviation history, airplanes and their means of propulsion have evolved and adapted. From primitive internal combustion engines and propellers to today’s modern turboprops and turbojets, commercial aviation has gained in speed, service ceiling and efficiency.
In this installment we are not going to talk about all types of existing engines or their history, but we are going to dedicate the next few lines to describe the largest aircraft engines ever built. On the other hand, if you want to know the fuels of the aircraft of the future, we recommend you follow this link.
Ultrafan engine
The engine that tops the small ranking of the largest aircraft engines is neither more nor less than the largest engine in the world to date. It is an engine with an air intake diameter of 140 inches (more than three and a half meters), which is currently in the prototype phase. By the end of the year it will be ready to start the ground tests. In 2012 Rolls-Royce announced the beginning of the design of this engine, called Ultrafan, developing it over practically a decade to make it a reality.
To achieve the desired power, endurance and energy efficiency targets, this engine incorporates a newly architecture core that helps optimize fuel burn, while reducing polluting emissions and enabling a 25% fuel efficiency improvement. compared to the first generation of Trent engines from the same manufacturer.
To achieve its objectives, the UltraFan incorporates components with high resistance to ceramic matrix heat, and a gear system between the inlet and the high pressure turbine that will help maximize its efficiency. The blades, made of a carbon-titanium alloy, and the composite material shell help reduce weight by up to 680 kilograms per aircraft. Its entry into service is scheduled for the end of this decade.
GE9X engine
On the other hand, it is also vitally important to highlight the GE9X, from General Electric. The construction of this engine began in 2016. It has a 3.40 meter fan and it entered service since last year, implemented in the new version of the Triple 7, the B777X. The engine provides a thrust of 105,000 lbf (470 kN).
It should be noted that, although larger engines are usually associated with higher fuel consumption, their implementation in aircraft with high cargo or passenger capacity helps to reduce their polluting effect. Thus, for example, the average consumption of an A380 (Rolls-Royce Trent 900 or GE / Pratt & Whitney GP7200 engines) with a flat load is approximately 3 liters x 100 kilometers for each passenger transported.
JT9D engine
Although this engine is already smaller than the two previously mentioned, it is important to take it into account because its manufacturer, Pratt & Whitney, ranks third worldwide in the market for the manufacture of engines for the aeronautical industry.
This engine, also known as the “Jumbo jet” because it was recently fitted to the Boeing 747, is available in three versions. The first, with an intake diameter of 2.4 metres, has been designed to power aircraft such as the Boeing B767, Boeing B747 and Airbus A300; the second, with a diameter of 2.5 metres in its front section, has been developed for aircraft such as the Airbus A330 twinjet; and finally, the third version, with a diameter of 2.8 metres, has been designed to power the Boeing B777.
After this review of the largest aircraft engines in the world, it should be noted that, beyond their dimensions, the manufacture of these engines has been designed to work on reducing emissions and improving them for sustainability.
On the other hand, the current trend towards a reduction in the number of engines in large aircraft – after the retirement of the B747 and A340, the only four-engine currently in service is the Airbus A380 (Withdrawal of four-engine aircraft) – opens a panorama for the future composed of twin-engine aircraft with larger powertrains, but at the same time more reliable and more efficient in energy consumption, and with manufacturing processes that are more respectful with the environment. Quite a challenge from which, for the moment, it seems that Aviation is succeeding.
Despite the fact that in 2020 many airlines were forced to cease their activity due to the covid19 pandemic, investors and entrepreneurs – with government support in many cases (30,000 million euros in aid granted in the EU during the pandemic) – have shown its confidence in the aviation sector as one of the engines for the recovery of the post-covid world economy, and for this reason it has already started the appearance of new airlines and the refloating of many of the existing ones.

We are still far from flying at hypersonic speeds, but the aeronautical industry is beginning to be in a position to carry out tests that bring us closer to that future reality. In fact, the Stratolaunch company designed in the first half of the decade what could have been the first hypersonic aircraft in history, destined to launch special spacecraft and satellites in the upper atmospheric layers, but the project at the time of this writing lines is paralyzed.
Although generally not visible, in the presence of water vapor or smoke turbulence can appear in the form of eddies. They are often called ‘waves of the sky’.
No doubt we have heard or followed the news of an emergency landing. The last one with media repercussions occurred in Madrid in February 2020, when an Air Canada Boeing 767 declared an emergency shortly after take-off. The plane spent up to six hours orbiting the Madrid sky before landing back at Barajas airport. The main reason for this manoeuvre was to get rid of several tonnes of fuel, the weight of which would have made landing impossible. Read more

During World War II, the world of aviation underwent an impressive technological revolution. Each time the aircraft were able to fly higher and faster. But pilots and engineers ran into the so-called ‘sound barrier’ over and over again. That is, the possibility of exceeding the speed at which sonic waves are transmitted through the air. Approximately 344 m / s at 20 ° C temperature, or what is the same, 1,238.4 km / h.

For students, future pilots, and even passengers with a certain concern to expand their knowledge, the automatic pilot of aircraft is not completely unknown. However, it is common to ask questions about its operation and role during the flight.

In recent months, we have seen how airlines such as Iberia, British Airways, or Qantas are withdrawing their four-engine A340 / 600 aircraft. At the same time, Boeing announced by 2022 the end of the manufacture of the B747. A legendary four-engine.
For a year now, the pandemic caused by COVID-19 has been affecting millions of people throughout the world. A health tragedy that directly affects the whole world economy and especially the aeronautical sector which is one of its major drivers.
In @easbarcelona we are convinced that the sector recovery will start in the coming months. However, we understand that students who have completed their pilot course during the last year have seen their expectations -of being able to access a commercial pilot job- delayed in most cases, with the consequent additional cost to renew their pilot license.
@easbarcelona will continue to support our students tirelessly in achieving their goal. To help them in these months, we have decided to facilitate the license renewal at no cost to all our ATPL Integrated Course students who have completed the course in 2020 and have not yet found a job in the sector. In this way they will not have to bear an additional financial burden for a period that, we hope and wish, will be short. By doing so, we hope to contribute to making this situation more bearable for all of our graduates.
The winglets of an airplane are the fins, they are usually vertical, and are located at the tip of the wing. These make it possible to reduce the induced resistance. In other words, they serve to prevent the air flow from the soffit from mixing with that from the extrados due to the difference in pressure between them.
