Hypersonic missile is preparing for testing

18.08.2017

The American company Generation Orbit Launch Services will soon begin a series of tests of the prototype of the promising hypersonic launch vehicle GOLauncher 1, which will allow launching various payloads on a suborbital trajectory. According to Aviation Week, fire tests of the rocket will begin in the near future, and then flight tests on the carrier aircraft. These checks will be conducted at the Edwards Air Force Base in California.

Currently, American developers do not have tools that would allow a wide range of research in the field of microgravity and high-speed atmospheric flight. Until 1968, such studies in the United States were carried out using the X-15 experimental rocket plane, which was originally designed for space flights from a carrier aircraft. Before the closure of the X-15 program, rocket planes with various equipment were used for research, the data of which were used, including in the development of American space programs.

The new hypersonic rocket will become a carrier for various measuring equipment, which will allow research not only in the field of microgravity, but also in astrophysics. In addition, the rocket can also be used to launch nanosatellites into space. As expected, during the first flight tests of the rocket, a modified Gulfstream III business jet will become its carrier. It will be used to determine the aerodynamic characteristics of the rocket and its effect on the launch vehicle flight parameters.

As expected, after fire and purge tests of the GOLauncher 1 rocket, Generation Orbit Launch Services will assemble the first flight prototype, which will be completely ready and will make its first flight on a carrier aircraft before the end of 2018. The rocket will perform the first undocking in the air and independent flight at the beginning of 2019. Shortly thereafter, the liquid-fueled GOLauncher 1 rocket will be used for the first research launches.

The mass of the new rocket will be 1,1 tons. Its engine will run on kerosene and liquid oxygen and will be able to produce a thrust of about 22,2 kilonewtons at sea level. GOLauncher 1 will be able to carry various equipment or nanosatellites with a total mass of 136 to 454 kilograms. The rocket can be used for research launches along suborbital trajectories with a height of 15,2 to 36,6 thousand meters with flight speeds of four to eight Mach numbers (4,9 to 9,9 thousand kilometers per hour).

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, ... >>

The miniscanner will determine the composition of any object 28.05.2014

The device, which weighs only 20 g and is slightly larger than a regular USB flash drive, will be able to “tell” at any time what kind of water we drink, what air we breathe and what material our clothes are made of.

The Israeli company Consumer Physics has developed the world's first portable molecular scanner SCiO, which can instantly determine the chemical composition of any object to which it is brought. The miniature device works on the principle of NIR spectroscopy (near infrared spectroscopy), writes Israelinfo.

The device, which weighs only 20 g and is slightly larger than a regular USB flash drive, will be able to “tell” at any time what kind of water we drink, what air we breathe and what material our clothes are made of. Journalists have already dubbed the device "Google of the material world", and science fiction fans compare it with hand-held scanners from the Star Trek series.

The device connects to smartphones and conducts chemical analysis of substances using special applications. Until now, such spectrographs were used only in industrial laboratories and were not available to the general consumer.

The project of the new gadget aroused great interest: on the KickStarter website in two weeks, almost 9 thousand people expressed their willingness to invest in it in the total amount of $1,96 million.

The company promises to start selling SCiO in January 2015 - with a trial series of 300 copies. The scanner can currently be ordered for a $199 project investment.
