Interesting, though already forgotten piece of Soviet military technology

Interesting, though already forgotten piece of Soviet military technology

Screens are structures that resemble airplanes and utilize similar physical phenomena, but operate only at a limited height above ground or water. Imagine the fear on the faces of Western generals when they learned that the Soviets had similar machines to speeding boats up to 650 km / h, capable of rapidly destroying US aircraft carriers. What’s more, many point out that the screenplays can come back to favor with Vladimir Putin.

In terms of construction, the screen is similar to a plane, or airplane. This demonstrates, for example, the hull construction, the presence of vertical and horizontal ballasts, and some steering surfaces. Shields usually had a relatively small extension of the rectangular outline, and their drive was a battery of several motors – up to eight and sometimes ten.

The principle of screen operation is almost identical to that of an airplane. This is primarily the use of the phenomenon of land influence. Any plane or screen that hoveres over a surface at an altitude of more than or equal to the span of its wings makes it possible to fly with significantly lower carrier forces than at higher altitudes. Just right above the surface of the earth or water to create a bearing force is the “air bag”, thanks to which the effective resistance is induced from 5 to as much as 65%. The higher – the greater the resistance. Thanks to this, the screen to perform the flight at this altitude required much less bearing capacity. This, in turn, translated into the ability to make a flight with much larger missile and torpedo charges. Theoretically, a screen with a proper loading configuration could fly and fly as an ordinary plane – but was not designed for it, and its task was to operate only in the area of ‚Äč‚Äčland effect.

Due to the fact that the screen was designed to move only at low altitudes, the structure of the wing could be much simpler. But the stick also had the other end: the need to operate on the seas created a risk of getting water into the engine air inlets. Contemporary passenger aircraft engines are designed to draw in a certain amount of water, but it’s nothing to do with the environment in which the …

Razer has announced a new Android TV console

Razer has announced a new Android TV console

Razer has so far focused solely on mouse accessories, keyboards, and headphones, but has been extensively expanding its Razer Blade range of laptops and tablets, and is now announcing its own console on the new Android TV platform.

Equipment that does not yet have a final name will play an entertainment center for our living room, which is connected to a large screen to stream music and movies, as well as video games. And they will not be casual productions, as the creative director of Razer, Min-Liang Tan, says the plan is to meet the expectations of hardcore gamers. That’s why the unit will be equipped with powerful components that allow you to run more complex and demanding titles. How strong, so far is unknown, because manufacturers have not yet spoken about technical specifications and equipment, but may choose to disclose it at the Gamescom Gamescom in Germany, which will take place in Germany.

The residual information is so far that the hardware will be supported by a dedicated mobile application, compatible with every tablet or Android smartphone, and you will be able to control it using voice commands.…

Fixed Solar Impulse 2 will go away

Fixed Solar Impulse 2 will go away

After nearly seven months of hiatus in Hawaii – caused by a malfunction – the electric plane Solar Impulse 2 will soon continue its great journey. The new equipment and the team responsible for this project are installed, hoping to prevent a repeat of last year’s situation.

Launched last year around the world’s first electric plane, whose main source of energy is solar panels, may soon be successful. The event started in March last year was discontinued several months later, during the trip from Japan to Hawaii. Although a five-day flight without any break allowed to break the record of flight length and distance traveled this amazing machine, but severely damaged it.

During the inspection in Hawaii, it turned out that the high temperature destroyed the storage batteries generated by the photovoltaic cells covering the wings, so the flight was impossible.

Over the past seven months, the machine was grounded as service work ended, replacing batteries, and installing a new battery stabilization and cooling system.

The 90-minute test flight showed no problems, so at the end of April Solar Impulse 2 will be able to continue the journey. Its first stage will be a four-day flight from Hawaii to the west coast of the United States, and then back to its starting point, Abu Dhabi.

Solar Impulse 2 is an airplane with a wingspan of up to 72 meters, so it is significantly larger than the Boeing 747, however, its weight is only 2300 kg. It was obtained through the use of carbon fiber, as well as the special technology used in racing yachts, which makes the plating three times lighter than paper. The machine is powered by four electric motors, which deliver 17,248 photovoltaic panels of just 135 microns thick, embedded in the wing surface and protected with fluorine copolymer. The energy produced by them is then stored in polymer batteries of a total weight of 633 kg.

Thanks to this drive the machine has almost unlimited range and moves at an average speed of 50-100 km / h.…

Windows 8 tablet with Windows 8 in the fourth quarter of the year?

Windows 8 tablet with Windows 8 in the fourth quarter of the year?

Nokia has been rumored for months by rumors. The manufacturer is still silent on this subject, but it is quite possible that the Finnish will enter the market with Windows 8 already in the fourth quarter of this year.

Nokia’s tablet has been in the media for a few months. All in all, your own tablet would be for the Finnish certainly a device that would complement the ecosystem for Nokia Lumia. Stephen Elop once said that the company would enter the tablet market only when it was able to offer an innovative device.

Meanwhile Digitimes, referring to proven sources, reports that Nokia’s tablet is likely to hit the market already in the fourth quarter of this year. Interestingly, the heart of the device is to be dual-core Qualcomma – Snapdragon processor (probably S4). In addition, it will be a tablet with a diagonal screen of 10.1 inches.…

The Chinese have created a car for solar energy

The Chinese have created a car for solar energy

Chinese automotive products are starting to slowly conquer the world and in a few years most of the cars found on the road will come from your center. Interestingly, not only big companies are involved in car design, but also companies that have so far had little to do with motoring.

China Vanke, one of the largest Chinese developers, has decided to be in a completely new market sector for him and has just finished designing his first autonomous car. The manufacturer assures that the tests of the new vehicle have been completed and will be ready for sale next month.

The car created by the Vanke engineers is certainly not as beautiful and looks like a cable car’s cabin, so to speak, its front and back. However, this is not particularly important, because it is an autonomous vehicle, so the passenger is alike anyway, because his role is to sit back and sit back and wait for the vehicle to arrive.

The car is powered by solar batteries that charge the batteries to provide enough power for the whole ride. There are six chairs in the interior, and the entire deck can travel at a maximum speed of 35 km / h and travel with built-in GPS or magnetic track.…

NASA technology will help firefighters

NASA technology will help firefighters

The work of firefighters is extremely dangerous as even asbestos overalls do not provide 100 percent protection against heavy burns. NASA engineers working with the Department of Forestry are working on a new thermal shield that will protect the lives of firefighters during forest fires.

Now firefighters fighting forest fires use cyanophyll weighing more than 2 kilograms to protect them from the heat. NASA engineers, however, believe that they can create a more effective solution by using space vehicle technology to prevent them from burning when entering the atmosphere.

The project began in 2013 after 19 firefighters lost their lives in the Yarnell Hill fire, with two NASA engineers, Mary Beth Wusk and Anthony Calomino, who used the new heat shield for future spacecraft and turned it into a cover, Which would protect firefighters from extreme temperatures.

After hundreds of tests at the Langley research center, they managed to create a prototype of such a shield. Now it will be handed over to the University of Alberta researchers who will be carrying out field trials to prove the effectiveness of the new technology.…

New drones of the American Navy

New drones of the American Navy

The MQ-8C Fire Scout UAS is the latest weapon of the American Navy, which has just undergone extensive testing. It is an unmanned aerial vehicle designed specifically for naval missions, which features a vertical launch and landing capability.

Drones used by the US military, usually take off from airports or are fired from special catapults. However, the Navy tests a completely new model MQ-8C Fire Scout UAS, which can take off and landing like a regular helicopter.

The MQ-8C is a newer, larger and more refined version of the MQ-8B Fire Scout, which can also land and take off vertically and is designed to operate in the Pacific. The machine made its maiden flight in the fall of 2013 and although it is still testing before entering service, the Navy has already ordered 17 copies of these unmanned.

New drones have greater reach and payload and can stay in the air for up to 10 hours. The unmanned carrier can carry about 330 kg of cargo with its maximum range of 150 nautical miles. The machine weighs a total of 1500 kg and can reach a ceiling of 6000 m. It is powered by a single Rolls-Royce engine.

The drive is based on the modified version of the commercial Bell 407 helicopter, and most avionics have been borrowed from the MQ-8B. The machine is equipped with FLIR’s BRITE Star II IR-based infrared light sensor, which illuminates the target targets for missiles, and uses it to measure distances.…
