Hybrid aircraft launched

05.01.2015

An intermediate link for adapting drivers and changing the priorities of automakers for a smooth transition of the global industry from purely gasoline and diesel cars to vehicles with an electric installation can be called the so-called "hybrids" that combine two power units at once. However, in this case, the electric motor often performs an auxiliary function, being included in the work instead of the internal combustion engine in the low load mode. In addition, the regenerative braking system used in hybrid cars also helps save fuel, allowing you to recharge the battery when braking to power the electric motor with free energy.

In a similar vein, researchers at the University of Cambridge and Boeing have developed the world's first hybrid version of an aircraft, introducing the world to a more environmentally friendly, fuel-efficient version of a compact, single-seat aircraft.

Test flights of the brainchild of Boeing and British designers were successfully completed a few days ago. The concept chosen for the project functions in the same way as the electric motor in hybrid cars. The design of the aircraft provides for the installation of one piston aircraft engine and an electric motor, which is activated and provides additional thrust only in certain cases. These include takeoff, climb, as well as various kinds of critical situations when there is a need for additional power.

During the flight in normal mode, the batteries are recharged from the piston engine. By choosing the most balanced mode of operation of the main power plant and the presence of additional electric traction, engineers managed to achieve up to 30% fuel savings. At this stage, the technology is far from being mass-produced on commercial aircraft, but already now it is showing very good results. Test flights of the hybrid aircraft took place in UK airspace, but the aircraft's flight altitude was limited to a modest 500 m.

“Despite the fact that hybrid cars became available a decade ago, the development of hybrid aviation has been hampered by modern battery technologies. Until recently, batteries were too heavy, bulky and did not have the proper capacity for such overall dimensions. With the advent of advanced lithium-polymer batteries the situation has changed, which made it possible to turn the concept of a small hybrid aircraft into reality today, "- shared his vision of the situation, project leader Dr. Paul Robertson (Dr. Paul Robertson) from the University of Cambridge.

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 ... >>

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, ... >>

Reproduction in space possible 26.05.2017

Japanese scientists have been experimenting with rodents for many years, as a result of which it turned out that reproduction is possible in space.

In 2013, biologists at Japan's Yamanashi University began a multi-year experiment involving mice. First, they sent frozen rodent sperm aboard the ISS. A year later, the material returned to Earth, they fertilized eggs, which were then implanted into the wombs of surrogate mother mice.

According to the results of the study, scientists published an article stating that one of the biggest dangers to living organisms in space is the high level of radiation. It is 100 times higher on the ISS than on Earth. Radiation can affect sperm activity and even alter DNA.

However, when the Japanese compared the DNA structure of rodents conceived in this way and rodents conceived in the usual way, they found no significant difference. There were no deviations in the cubs of "space" mice.

For the first time, viable offspring have been obtained from genetic material irradiated in space. Scientists intend to continue their research.
