high speed jet engine

26.12.2020

Scientists from China have developed an air-jet engine, the capabilities of which allow you to fly around the planet in 2 hours.

During testing, the engine was able to exceed the speed of nine Mach numbers, however, this level is able to increase, because during the test, not very powerful equipment was used, which reduced the capabilities of the device.

The motor accelerates to Mach 16 - in this case, aircraft can go around the Earth in just 2 hours.

At the moment, only a prototype is being tested, for this reason, the full implementation of the project is expected by 2023.

The scientists gave some details about the engine: hydrogen fuel is ignited using a shock wave. The alloys used in the creation of the prototype can withstand quite a high load and temperature.

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 ... >>

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, ... >>

Vulcan launch vehicle 24.04.2015

The American aerospace company United Launch Alliance (ULA), an alliance between Boeing and Lockheed Martin, is developing a new Vulcan launch vehicle that will replace the Atlas V and Delta IV heavy rockets.

The first stage of the Vulcan will use American liquid fuel engines, since the use of Russian RD-180 engines on the current Atlas V rocket does not suit the United States for economic reasons.

In order to reduce the cost of operating the rocket, the Vulcan first-stage engines are planned to be reused after they land, for which scientists are developing a protective system that will prevent overheating of the shell from friction in the atmosphere, as well as braking parachutes.

ULA plans that in the future, Vulcan will be able to surpass the capabilities of the Delta IV Heavy rocket, which has the largest payload of any launch vehicle in operation today in the world and is capable of launching payloads of up to 25 tons into low Earth orbit.

The first launch of Vulcan is expected to take place in 2019.
