Technology that keeps aircraft to fly for very long flight flights

Increasing the wings is one of the reasons why the A350-900 can fly from New York to Singapore-the tallest flight in the world-with only two motors. Another decisive factor is that over the past thirty years, aircraft engines have become largely more efficient, although basic turbine technology remains the same.

Improvements include progress in manufacturing lighter engine codes made of carbon fiber compound that constitute weak strength and lighter than titanium blades; Founded cooling systems; And advanced control programs that monitor important data during the trip such as air pressure, temperature, air speed and more. The optimal location of the engines on the wing has also been improved.

“If you look at 747, with four engines-you can now provide the same amount of payment on two engines that burn 20 to 30 percent of those engines that were produced 20 to 30 years ago,” says Carrie Grant, Assistant Professor of Air Science at the Air University Air University in Pressota, Arizona.

The difference lies in how the engines use air flow. The turbojet engines used in older planes force all the air in the essence and combustion room, generating the payment by removing the exhaust gases from the back at high speeds. This process used more energy and was much higher than the newer engines.

Long -term modern aircraft use the so -called high -bread engines, which use a system that allows a large size of air to flow around the heart of the engine. Payment is created, then, primarily by the large fan at the front of the engine – one part can see it directly – unlike the exhaust that shoots the back. This design has greatly improved the efficiency of the engine with an increase in the percentage of heavy air.

New engines produce an extraordinary amount of energy. The General Electric High-Spass, Genx, which refers to Dreamliner, is wide like the fuselage in Boeing 737. According to the GE website, the engine has a 10: 1 dedicator, which means that there are 10 times the air wandering out of the engine instead of the essence of the engine for combustion.

The design with the help of the computer also made the blades more efficient and stronger, allowing it to rotate from 30,000 to 40,000 rpm. “You should be able to have structures that can afford this type of rotational tension and collusion,” says Grant. The ceramic materials used in the heart of the engine allows the temperatures of internal operating higher than the high -based metals based on nickel, which are currently used in most engines.

The use of lightweight compound materials, which are carbon fibers, in the plane’s wings and the body of the plane has greatly reduced the total weight of the plane. The lower weight of the plane, the more the energy is required to operate it.

Comprehensive designs for these aircraft are more dynamic as well. The wings on both A350 and Dreamliner variables are thinner than previous generations, fuse designs, especially the dolphin -like Dreamliner, is generally created less.

In the cockpit, new technologies simplify experimental control and problem solving through advanced counter -feeding systems, helping to reduce the burden of experimental work and increase performance. Today, long today’s aircraft allows a semi-independent-independent flight, that technology is already present for full independent flights, even for large commercial aircraft.

Even the experience of passengers has improved, although the frequency of this technology may not keep pace with those in the same plane. The biggest difference between commercial aircraft today and previous generations is the ability to control the compression of the cabin, moisture and air rotation. “When Boeing 787 produced, they managed to keep the atmosphere moisturizing,” says Grant. “This alone is a great improvement for people- as you know, after a nine or 10-hour trip, was as if you were suffering from corn companions in your nose.”

Another main improvement in long -range trips, according to Grant? today Wi-Fi airlines Really good.
