, from precisely controlling the internal atomic structure of the metals to create turbine blades that are actually a single glass of robotic delicate that humans could have dreamed of Jet of Jet to which the houses of the jet engines of the jet are to which the engines of the jet aircraft engines of 194 are more powerful and are more efficient, the Dreamliner engines are so large that they are the same diameter as the fuselage 737 and this is only part of the puzzle that has allowed the 787 DREAMLINER to break worldwide March 2020 in the middle of a global pandemic of the United States.

Tahiti was no longer a creative solution to replace its regular flights between the Tahiti International Airport and the Charles Deal airport, which under normal circumstances stopped in Lax confronted with an interruption of Air Tahiti began to operate the longest flight of the 16 and 1/2 hour 15,700 km without the flight of Tahiti and Paris, the longest and longer flight, the longer and longer flight. News at national height is the current flight at the national level. We are going to learn how in our last video we explore the incredible

that has become the fuselage sculpture of 787, but all that work is useless without an energy system so that Boeing will transform the shape in all of us have seen images of the people who draw by hand the old planes fed by the piston to begin, this is obviously not feasible for the reaction engines that must turn at very high speeds to start the engineers to start the engineers to start the engineers to start the engineers to start the engineers to start the engineers to start the engineers to start the engineers to start the engineers to start the engineers to start the engineers to start the engineers to start the engineers to start the engineers to start the engineers to start the engineers to start the engineers to start the engineers.

Ways to complete this work, some engines use explosive cartridges that resemble shock canes that can be fired through an electric charge that hot gas is expelled by the car, a smaller turbine, which can be operated by the load that will be triggered to the load of the electric charge that will be expelled to a smaller turbine that is a thrust that will be triggered to the load of a smaller turbore Load. The reduction equipment that allowed the smallest turbine that the engines accelerate the initiators of the cartridge were popular in the oldest military aircraft that may need to enter short -term short -term air with limited land support, some airplanes, such as SR71, had a direct starting car that connected two massive v8 engines directly to the J58 engine from below, below the NEL to obtain the power 4,500 rpm rpm.

Fed to the turbine section directly so that the engine moves, this can be done with an external cart called flee People are not aware of this mini mini turbine engines, the aircraft engine may be small. The commercial aircraft of the APU of 787, like other planes, begins by a small battery, but from here the architecture of the 787 system is very different, the Apu 787S, like other airplanes, begins a small battery, but from here the architecture of the system 787 is very different. The 787 with incomparable electric energy a traditional plane has a generator in each engine and another in the APU, but the 787 is anything that is not traditional, in total there are six generators on board on board with two pairs in each engine that provides the main power each capable of generating 250 kow with two more in the secondary power provided by each capable of providing 225 kW if the six of these generators were working 1.45 more in the secondary power of the power of the 75 kW at 75 kW at 78. times more than a triple 7 is capable of producing that in perspective, this is a 787 in a football field if it is necessary The 787 and the one that accelerate the 787 use a traditionally bleeding air architecture to the plane air systems traditionally.

Reaction engine compressor section The APPO normally causes hot air to the engines to start and then, once the main engines start, the hot compressed air bleeding from the section of the transmitting compressor. and the pressurization system where part of the air cools using a heat exchanger that uses the outer air from an intake mounted on the surface called ram intake to remove the heat from the engine of engine bleed It does not use the system that its system is obviously the cabin is a pressure that is obviously the cabin. We now have two in led the Ram air inlet and the cabin air compressor inlet the cabin air compressor leads to you guessed it the cabin air compressor an electrically driven device that compresses the air for the passnger cabin This compression process heats the air up too a lot for direct use uses into the cabin I require subject cooling using to heat exchanger cooled by the Ram Air Inlet You Can See This Little Door Open While The Planet is on The Ground and It Serves To Protect The Inlet From Foreign Objects Entering It Another Energy Intensive Process That Has Been Handed Over To The Electric Motors Is The Braking System As You Can Imagine The Energy Required To Slow Down A 200 Ton Plane Traveling at 270 Kmph is not small calculating the energy require Lot of Energy and the Vast Majority of that energy to be dissipated by the brakes of the plane's inverse propellants can deploy that it redirects the air of the derivation ducks through the slots that open on the motor side, so the brakes must convert a large amount of kinetic energy into another form of energy of energy of energy.

A landing at that point beyond that point, the plane has to take off when the plane stops complete, the brakes are shining in hot red, typically the braking mechanisms of the plans are driven by hydraulic with a hydraulic piston that forces the brake pads against the wheel to reduce the speed of the plane, the 787 eliminated this hydraulic system and the hydraulic system and the hydraulic system that act by the electric motors every eight of the eight of the eight of the eight of the eight. However, between 62 and 111 kg weight of 787, while it is drastic, easier to maintain and install 787 has a hydraulic system, but has eliminated two large hydraulic pumps of bleed Alpendiums would overload the other pumps that feed the hydraulic system during the landing system of the 7887.

In itself of these pumps with BL air engine and replace them with electrically more efficient driven pumps to start the 787 it is capable of generating higher hydraulic pressures that allow it to use smaller hydraulic components that save weight and space so that the majority of the system of the system We have touched the revolutionary engines in themselves, the same Kons of the 310 almost the same confidence that the generation generation engines of General Electric, the CF6 equipped with the 767, was able to produce, but the GE Nx produces this trust while consumes 15% less fuel that is an incredible leap in technology.

Turbine and nozzle The ultimate goal of a reaction engine is to draw the air and pressurize it as much as possible, which increases the air energy potential before mixing with fuel and turning it on causing a rapid expansion and acceleration of air acceleration, the work done by the compressor is recovered in the section of the turbine They recover in power and recover in the power of the NOES of energy and access and accelerate through the NOES of energy and are accessed through the NOES of energy and access and access through the uniones. On the back of the engine to provide the engine core, this part of the engine is what feeds the engine, but most of the air that travels through the GX through the walks by this section completely only passing through the fan and through this derivation duct, and this is one of the reasons why the engine is so incredibly efficient, the bypass ratio have increased during the years, what is one of the years, what is one of the years, what is one of the years.

Reasons of the reasons that remain larger, the Genx engine has a bypass -ByPass engine from 9 to 1 to 1 of the years that is 1 of the years that have increased the air from which there is a wing of the years that passes through the air of the years. The 9 kg engine core flow through the derivation duck this is extremely high. The engine that replaced the Genx only had a 5.7 bypass that during its time was a very high derivation ratio, while the nucleus takes a small volume of air and quickly accelerates the fan that takes a massive air volume and accelerates only a bit that does not require that it mixes with fuel and ignite this fan, the fan increases the fuel of the efficiency of the plane.

Gigantic Propeller The industry has been pointing to increasingly large referral relationships, but there are a couple of limiting factors that make it difficult centrifugal, and centrifugal forces, and fans' fan forces are much larger than the fan, the fan speed tensions, the fan speed tensions, the fan forces that can be the fan speed of the fan speed, the fan forces that are the ones that are the ones that are the ventil. For wave shocks and a massive increase in drag, the first problem that we must address is how to handle these centrifugal forces, the magnitude of the centrifugal force can be found using this equation where m is the mass w is the angular velocity and r is the distance of the rotation center, so our force, so our force will be the weight of the speed of the speed of its rotation and its diameter we want to increase our diameter to increase our diameter peso, por lo que aumentará el peso, por lo que aumentará el peso, por lo que tendrá el peso de la velocidad de la velocidad, y aumentamos a nuestro diámetro para aumentar nuestro diámetro para aumentar el peso, por lo que aumentará el peso, por lo que aumentará el peso, por lo que aumentará el peso de la velocidad de la velocidad, y aumentamos a nuestro diámetro para aumentar nuestro diámetro para aumentar el peso, así que aumentará el peso, así que aumentará el peso, por lo que aumentará el Weight, so the weight will increase, so the weight will increase, so the weight will increase, since the weight will increase.

Decrease in our weight or decrease in our rotation speed The GE NX achieved the first requirement through the use of light carbon fiber fan blades, the oldest fan knad Titanians allow carbon fiber blades that are reduced to Titanium Titanium. The recount of blades from 22 to 18 in all this resulted in a weight savings of 15% in the blades that allow them to turn faster without worrying about damage, however, the compounds have a great fall in their impact resistance, one of the tests that the engine must pass to reach the scope certification is the chicken gun test that, as there may be, as it implies that it is still a dead bird in the engine and seeing how the blades of the blades of Fans are the first part of the engine, the foreign object that will be the engine and, therefore, the objective of which the engine must be, and, therefore, the objective, and, therefore, must be the engine, and, therefore, must be theMotor, and, therefore, it must be the engine, and, therefore, it must be the engine, and, therefore, it must be the engine, and, so it must be the engine.

The early impact of the development of NASA composed fan blades showed that the blades composed of the elves simply were not up to the task to solve the problem. The attack edge of the blades is reinforced with the Titanium Bypass relationships, they are likely to continue growing as our technologies develop speed gear between the main transmission axis and the fan of fans who can allow engines manufacturers to increase the byning relationships, even more pratones, this technology is used in their technology, in their technology, in their technology, in which the fan can make the fan. Motor manufacturers are from engines manufacturers, they are promoted to the relationship, even more, more pratones are used, this technology is used in their technology, in their technology.

The largest derivation ratio ever seen in a commercial airline turbophane engine included a planetary gear between the main transmission axis and the turbophane transmission axis that applied a reduction of 3: 1 in the speed that allowed the turbo fan to turn at a lower speed of 4 to 5,000 rpm, this stops the ventilator to grow in the diameter as the larger forces have been reduced to The largest spots that had been drastically reduced with a lower speed that give a record speed to a rule record. The design of its new LEAP engine currently in use by 737 Max, but the problems with the weight and maintenance of the planetary gearbox deterred them and that the hesitation may have been justified since the engines have had a history of turbulent operations with several bases and removals of engines, although these problems were not directly the result of the planetary gears, however, as the technologies improve, we improved several designs of these designs. that are used for the designs to be used for the designs to be used for the designs in neighbors so that they are used for the designs in neighbors so that they are used for the designs in the engraved ones for those used for the designs in neighbors for those used for those used for the gear designs for those used for those used for those used for the designs.

For neighborhood designs for those used for designs in the engraved. Pressure at the Exit of the Compressor Section by The Pressure At The Inlet This One Variable You have Hug Implications for A Plane's Fuel EFFICIncy and Just As We Can See A Clear Upwards trend for bypass ratios over time Maximize the energy we can extract from our fuel because there is a more useful energy available for extraction in our turbine and nozzle than if we compress less the air, but it is not as easy as increasing the pressure through our compressor to achieve a higher compression that we must also have a number of higher advantages of the compressors, which will increase the highest weight and reduce the highest advantage and reduce the advantage of the advantage. which can cause a failure of the material on the pales of the compressor and perhaps most of the temperature temperature in the increase in emissions of powerful greenhouse gases such as nitrogen oxides nitrogen oxides that oxide formation rates feeds its high pressure air in 22 fuel mixes located in a ring around the compressor that its work is quite simple to mix the fuel in the air and Turning it a simple work that began to develop in 1995 with the general electricity and NASA, the art of developing the perfectly complex fuel injection nozzle is incredibly complex, a thin but thin process as an orchestra whose Céscendo is a iron that is a skillful one for the vote.

Create a fuel injector with a complex internal labyrinth of air channels that traditional tools simply could not cut the fuel injector they developed is called the pre-molin annular pre-molin injector or the taps. Stociometric air fuel mixtures that are mixture where air and fuel are consumed completely in the reaction This is the area where nitrous oxide emissions are higher because the flame temperature is higher to minimize nitrous oxide emissions. We map the combustion process for the anterior injector of GE installed to more than 22,000 CFM56 engines that we would see that the air fuel mixture is initially injected into this area with a rich mixture of air fuel, then it passes through a dilution process to reach a lean mixture where the fuel is complete Business, the problem is that fuel is that fuel fuel passes through the stochametric region between these two phrases in a great offer of a great business of the tause of the tauses.

Thus, with a central main pilot surrounded by a main ring -shaped injector that creates two swirl air flows that see something that uses a large amount of air in the foresting phase to guarantee an exhaustive mixture and a mixture of lean air fuel if we assign the combustion process of the blows, but it starts even thinner in the thinner design in the fuel that never approaches the region of Peak oxide oxide, but which can be a simple device, but begins with the design of a simple device, but a thinner design of combustion combustion combustion is performed, but it starts with the simple design of a simple device, but it starts with the design of a simple device, but it is taken to the generation of a fuel device of the combustion of the combustion of the combustion of the combustion of a device.

The simulations gradually bring engineers closer to their target and none of their designs would have been possible without the current metallic impression of current generation that could manufacture the complex parts with the materials capable of resisting the enormous heat within the fuel 26 years of development paid with 60% reduction of nitrous oxide oxides. The number of compressor stages Each of these turbine discs is a stage, the GNX contains 10 stages to less than the CF6 engine that is replacing GE managed to do this through a new improved blade design that is much less information than what I wanted to share, but finding information on this topic is incredibly difficult to see how I have seen how advanced and secret technology is the compressor that makes the compressor that makes the compressor that makes the compressor that makes the compressor that makes the compressor that makes the compressor that makes the compressor that does the compressor that does the compressor that does the compressor.

The compressor stages are performed by joining the blades to a separated disk with Dovetail connections, this decreases the complexity of the manufacturing, but the doovetail connection is less durable, increases the assembly and maintenance costs and allows some air to escape through the connections that lovers are the compressor stages that are manufactured from a single metal to improve and easier to install and easier to install than to install They improve the improvement of aerodynamic efficiency efficiency. And, of course, that should be applied to the turbine section that feeds the compressor that also benefited from avant -garde aerodynamic modeling, the turbine also made use of new advances in material sciences, being the first commercial engine to use Gamma Titanium aluminum, an advanced alloy of titanium and aluminum that combined the containers of the resistance of the resistance of the Titanium The weight of the titanium titaniums of the Titanium.

Take This Material From The Lab To Commercial Use and The Dreamliner was The First Plane To Make Use Of It Paving The Way For The Materials Acceptance In The Industry All of ToSe Factors Combined To Allow The Ge Nx Engines of The Dreamliner To reduce Fuel Consumption by 15% Over Previous Generation Generion Eng That Is an Astronomical Leap and On Top of All that the Engine is 60% quiet than similar sded plans in part Thanks to the Engine's Most distinctive feature This Sawtooth Pattern on the fan casing and the engine Science These characteristics are called chevrons of the engine and are not just a futuristic cosmetic design, but the functional parts of the engine that significantly reduce the engine noise shape in a nozzle outlet in the general noisy contamination produced by the aircraft because the aircraft of the turbophafán engines forces the bypass cameras and the mobs and the mobs at the speed of the air speed of the turbones with the air of the air of the air of the air of the air, the outdoor with the air of the air of the air The air of the air speed of the turbhers.

Vortex causes do not control that in turn generate excessive noise for both passengers and the community on the ground think about it, such as water that accelerates a waterfall and hitting the water under that turbulence can be extremely noisy. It is said that it reduces the noise of the explosion of the jet by up to 30 % and allows Boeing to use a substantially less solid installation in the fuselage walls of the aircraft that helped reduce the weight of the aircraft. The 787 really lives in his name. The most advanced engineering that we have covered and is a plane that many of us will have the opportunity to fly and marvel at the decades of engineering advances that made it possible for this almost half -hour video to be only half the story, but the complete version of the director of one hour has been available in Nebula for more than a week.

Explanation of the thermodynamics of why compression relations really increase efficiency because it felt too academic for YouTube, but I think that fans of the diarma of this channel can enjoy listening to a 10 -minute explanation of the temperature temperature entropy diagrams.
