Supersonic passenger aircraft AS2

31.07.2020

The private American company Aerion Supersonic is going to start serial production of the promising AS2 supersonic passenger aircraft in 2023.

Aerion Supersonic has been developing the AS2 passenger aircraft since 2014. The length of the airliner will be 52 meters, height - 6,7 meters, wingspan - 18,6 meters. The maximum takeoff weight of the supersonic aircraft will be 55 tons, the AS2 will be equipped with three engines, the thrust of each of which must be at least 69 kilonewtons. The aircraft will be designed to carry up to 12 passengers. AS2 will fly over water at a cruising speed of Mach 1,4-1,6, decelerating to Mach 1,2 over land.

The reduced flight speed over land and the special aerodynamic design of the airframe will allow, as the developers expect, to almost completely avoid the formation of shock waves characteristic of supersonic aircraft. The flight range at a speed of Mach 1,4 will be 7800 kilometers, at a speed of Mach 0,95 - 10 kilometers. Currently, international regulations prohibit supersonic aircraft from flying over populated areas of land.

The first flight of the promising AS2 supersonic passenger aircraft is also planned for 2023 - it will be timed to coincide with the 20th anniversary of the last flight of the French Concorde supersonic passenger aircraft. Aerion Supersonic intends to complete certification of the aircraft by the end of 2025. At the first stage, the volume of production of aircraft will be small, but later it will be brought up to 36 aircraft per year.

The US Federal Aviation Administration (FAA) recently published a draft regulation for the certification of supersonic passenger aircraft and noise requirements. The new Supersonic Level 1 certification category will include aircraft with a maximum takeoff weight of no more than 68 tons, capable of flying at a speed of no more than Mach 1,8 - most of the current developments underway in the United States.

For heavier or faster aircraft, an additional category may be developed. Noise levels for supersonic aircraft are required to exceed current Stage 4 requirements, but will not be subject to the new Stage 5 standard. Noise requirements for supersonic aircraft in supersonic flight are under development.

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, ... >>

A giant hole has appeared in the ice of Antarctica 09.10.2017

A giant hole appeared in the ice of Antarctica. Scientists say that the size of the polynya reaches 80 kilometers and call it remarkable.

This is a huge polynya, in which pieces of ice are sometimes found. A similar phenomenon was observed in the Weddell Sea in the 70s, but it was not possible to study it in detail.

Such formations can influence climate change on the planet, however, they cannot draw final conclusions in the form of a small study of the object.

Scientists believe that when the sea ice begins to melt, a serious temperature contrast appears between the ocean and the atmosphere. It can start convection, then cold water sinks to the bottom, and warm water, in turn, rises to the surface of the ocean and continues to destroy the ice.
