Wings compound and folded

27.01.2016

Not so long ago, Boeing announced the completion of an important stage in preparation for the production of the future flagship of the Boeing family of passenger aircraft, the Boeing 777X model. The development of the so-called. "hard configuration" including the basic design and main features, as well as wind tunnel testing and structural load analysis. Detailed development of components, assemblies and other aircraft systems is next in line, after which it will be possible to launch the 777X into production.

One of the aircraft's most notable innovations will be 3,5m long wingtips that will fold vertically when taxiing and in the parking lot and deploy in flight. This will increase the working wingspan to 71,8, but at the same time retain the ability to use the existing runways and terminals, since the folded wingspan will be 64,8 m.

The company has not yet said how the rising wingtips will securely attach to the wing, although abnormal operation of the wingtips in flight could lead to disaster. Yes, and wings of this size, made of composite materials, should be able to withstand the usual load. However, Boeing has no doubts about the capabilities of the new aircraft, since structural tests carried out on the 787 showed that wings made of such materials can buckle above the tail and not break within 20 seconds.

With the new wings, the Boeing 777X promises to be the world's most fuel-efficient twin-engine airliner (in addition to being the largest). The variable wing shape will reduce fuel consumption by 12% and operating costs by 10%. This circumstance allowed the company to receive preliminary orders for 320 aircraft from six operators. Production is due to start in 2017, with the first aircraft entering service in 2020.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Healthy sleep eliminates sugar cravings 17.01.2018

Researchers from King's College London claim that if a person sleeps for a long time, he eats less sweets. Several dozen people participated in the experiment; some of them were instructed on how they could prolong their sleep (the instructions were pretty simple: don't drink coffee at night, don't go to bed with a full stomach, but don't go to bed hungry, etc.). Then they were sent home with special devices with which it was possible to monitor how much a person sleeps and how he sleeps.

It is known that an adult should sleep for about 7-9 hours, but not everyone manages to withstand this norm. So the participants in the experiment usually slept less. However, those who were asked to follow the "sleep" instruction during the week did start to sleep more - half of them increased their sleep time by an average of 52-90 minutes, and three managed to achieve the required 7-9 hours per day.

But the most important thing here is how their diet has changed. It turned out that those who began to sleep more began to eat less sweets: they put less sugar in tea and coffee, they were not so drawn to sweet pastries, etc. On average, long sleep reduced sugar intake by 10 grams per day. True, not very many people participated in the study, and the results obtained will still have to be checked. However, if everything is so, and sleep really helps to forget about sweets, then recommendations for those who want to lose weight can begin with advice to sleep longer.
