For example, the pair of seemingly fragile wings can bear a weight of nearly 100 tons? What kind of secrets are hidden inside?
"This is probably a question that many people have been asking for a long time." At a lecture on aviation science, Dr. Wang, a senior aeronautical engineer, solved the mystery to the audience.
Dr. Wang got straight to the point: "As one of the key components of a large passenger aircraft, the design of the wing can be said to have been repeatedly refined and perfected. It is not only about ensuring the safety of the aircraft, but also about factors such as fuel storage and center of gravity balance. "
The audience was solemn. Everyone listened attentively to the expert's explanation, for fear of missing a single key detail.
Dr. Wang continued, "You may not realize that there is actually an 'oil storage chamber' hidden inside the wing. That's why, even though the wings look so thin, they can hold nearly 100 tons. "
I see! A three-dimensional picture instantly came to mind: a huge passenger plane, soaring gracefully in the blue sky, and inside its wide wings, there was such an amazing storage of fuel tanks!
"But what are the deeper considerations for this practice of installing fuel tanks on the wings?" Some people in the audience couldn't help but ask questions.
Dr. Wang smiled and began to speak: "In the early stages of aircraft design, engineers were faced with a difficult problem: how to store enough fuel in a limited space to meet the needs of long-distance flights?"
"Obviously, if the fuel tank is installed inside the fuselage, it will not only take up a lot of valuable cabin space, but also affect the distribution of the aircraft's center of gravity, making it more difficult to maneuver."
After a pause, Dr. Wang continued: "So, the designers set their sights on the wings, which are natural 'oil depots'. With its large volume and space, the wing became the preferred location for storing fuel. "
"Moreover, this not only makes full use of the interior space of the aircraft, but also reduces wind resistance and improves the fuel efficiency of the entire aircraft." He summed it up this way.
The audience erupted in admiration. It turns out that behind these seemingly "natural" designs, there are such subtle engineering considerations!
"But it's not enough to just have the fuel tank inside the wings, we also need to make sure that the fluid doesn't wobble and leak during the flight." Dr. Wang said earnestly.
"After all, once a problem occurs, it will not only seriously affect the flight balance of the aircraft, but also may cause irreparable tragedy."
Everyone couldn't help but gasp. Indeed, an aircraft flying at high altitudes can have unimaginably catastrophic consequences in the event of any malfunction.
Seeing this, Dr. Wang hurriedly reassured: "However, don't worry, the designers have already thought of this. They used a variety of advanced protections inside the wing fuel tanks. "
"First of all, they divide the inside of the tank into separate areas, so that the fluid doesn't flow freely inside the tank, even in the midst of severe bumps."
"At the same time, various cushions will be set up on the inner wall of the tank to absorb vibration and impact from the fuselage and protect the fuel tank from damage."
"In addition, special sealing materials are used at the pipe connections to ensure the tightness of the fuel delivery system and avoid leaks."
Dr. Wang gushes these details as passionately as if he were describing a work of art.
The audience at the scene all sighed that there was such a sophisticated design behind this seemingly simple wing structure. This not only reflects the professionalism of the aeronautical engineers, but also demonstrates their ultimate pursuit of aircraft safety.
While everyone was immersed in this interpretation, Dr. Wang added: "Of course, as technology advances, the way aircraft stores fuel will also change in the future."
"Hydrogen aircraft, for example, are a good example." He paused, "Compared with traditional fuels, hydrogen is cleaner and more environmentally friendly, and it is expected to become the new favorite of the aviation industry." "
"However, this also presents new challenges for aircraft design. After all, hydrogen has a very different density and properties than gasoline, and it may require significant adjustments to the airframe structure to store enough energy in a limited space. "
"At the same time, the highly flammable and explosive nature of hydrogen also brings new hidden dangers to the safety of aircraft, and more reliable protective measures need to be developed."
Dr. Wang's deep eyes reveal his longing and worry for the future. The audience also fell into deep thought. "As ordinary people, we often fail to understand the intricate craftsmanship behind the aircraft, but it is their hard work that ensures that we fly safely every time." The middle-aged man sighed.
There was another round of warm applause from the audience. Dr. Wang smiled apologetically and said, "I'm just doing my best to educate everyone about aviation." In fact, the design and manufacture of aircraft is far more complex than I have just described. "
"For example, for a large passenger plane to fly at high speed in the sky, wings and fuel tanks are not enough. We also need to carefully design many key components such as engines, control systems, and communication equipment to ensure that the aircraft can fly safely and stably. "
"And, during the manufacturing process, engineers repeatedly test and optimize parameters to ensure that every part meets the highest quality standards. Only in this way can the risk of accidents be minimized and the lives of passengers can be protected. "
Dr. Wang's words reveal a strong sense of responsibility. The audience was in awe.
"Therefore, the manufacture of aircraft is not a simple matter, and it requires a lot of manpower, material resources and technical investment." "That's why the aviation industry has always been regarded as one of the most technologically advanced. "
"Each of us should cherish the hard work of these unsung heroes and thank them for creating such a safe and comfortable air journey for us."
Applause rang out again. Everyone nodded in agreement. After feeling the professional quality and sense of responsibility of the aeronautical engineers, they also have more awe and reverence for this industry in their hearts. "So, what will the aviation industry look like in the future?" A young man couldn't help but ask.
Dr. Wang's eyes lit up and he said, "That's a very good question. In fact, with the continuous advancement of science and technology, we have reason to believe that the aviation industry will definitely develop in the direction of more environmental protection and efficiency. "
"For example, the hydrogen energy aircraft mentioned earlier is a good example. The aircraft uses clean and environmentally friendly hydrogen as fuel and has almost zero carbon emissions, which undoubtedly makes a positive contribution to environmental protection. "
"Of course, there are still many challenges to achieve the commercial application of hydrogen aircraft. For example, the storage method and safety of hydrogen need to be further addressed. "
"However, as long as we maintain an innovative attitude, we believe that we can always find the right solution." Dr. Wang said with confidence.
"In addition, new types of aircraft such as electric aircraft and solar-powered aircraft are gradually appearing in our field of vision. They may not yet be able to completely replace traditional turbojets, but they point the way in a new direction for the future of aviation. "
"In short, the future of the aviation industry is full of possibilities, both from the perspective of environmental protection and technological innovation." Dr. Wang concluded, "I believe that as long as we continue to explore and innovate, we will be able to drive the aviation industry forward. "
The audience was amazed by Dr. Wang's vision. Some people can't help but sigh: "Listening to what you say, we seem to be able to foresee that future aircraft will not only be safer and more efficient, but also more environmentally friendly and energy-saving." It's exciting!"
Dr. Wang smiled and said, "Yes, this is what I have always dreamed of. I believe that as long as we unite and work together, we will be able to contribute our part to this blue planet. "
"So, friends, do you have any more thoughts and expectations for the future of aviation?" Dr. Wang finally issued a call to the audience.
The audience suddenly burst into a heated discussion. Everyone spoke enthusiastically and talked about their various ideas and imaginations for the development of aviation science and technology.
This lecture not only allowed the audience to gain a lot of professional knowledge, but also aroused their love and yearning for the aviation industry.
Finally, Dr. Wang smiled and said, "Alright, that's the end of today's lecture. Thank you for your active participation, and let's look forward to a bright future for the aviation industry!"
The audience applauded one after another, and all of them left deep thoughts and expectations. I believe that from today onwards, they will have a new understanding of those aircraft that are high in the sky. #机翼能承受近百吨的重量, what kind of secrets are hidden inside?
