Thruster

When we say "thruster", almost always are referring to Tunnel thruster. That is called the thruster unit, which is a transverse cross-cutting tunnel, or simply, a pipe, below the waterline and extending from side to side, with a propeller inside. Running propeller creates a stream of water, whose pressure and turns the ship in the right direction, or both they say, creates stress. To change direction or using a reverse engine propeller with variable pitch, which can turn the blades. Another option is to use two propellers. For even more details, read what Gazprom says on the issue.

On location thrusters are bow and stern. Depending on how you allocate the drive hydraulic, mechanical and electrical thrusters. Interestingly, the term 'thruster device "is also called electromechanical systems, with the function or type of autopilot autopilot, ensuring the continued direction of the ship, for example, strictly on the wind. Given the fact that the tunnel IP permit control the yaw caused by the wind on the nose of the vessel, to determine the precise meaning of the term is problematic. The basic task of thrusters on board is to increase maneuverability. Anyone who has ever tried to maneuver the yacht complete with rudder, I realized what it means to enjoy the controls. But that disproportionately important thruster – a important element of security in a mooring in a strong wind and current, or in cramped conditions the yacht club. When choosing a steering device, the first stage, you have to determine its type. The presence on board hydraulic tank and pump or main engine with a special PTO strong argument for installing a hydraulic PU.

Anastasia

What about for so long dreamed of all drivers in Kiev, has come true! In Kiev, earned a fully private company, hanging on for 6 months on the roads of more than 70 cameras. And unlike "gaishnyh" devaysov they all work. Clock. And most importantly: they can be viewed on the website online at least until the vision loss. Except you, this news will please you know much living on the upper floors of the houses on prosopektu Victory and other problem routes.

The site has delivered them from your daily calls: "You are my friend? Tear off the console and look, there goes avenue in your direction? "Webcams are hanging on the busiest street corners, crawl and Paton, Moscow and South bridges, and software makes do with a bunch of pictures of useful things. The number of webcams grows slowly. There golosovalka over the next installation site. If the number of votes and technical conditions permitting, a webcam will be there. By accessing and organizing a personal account, you can of webcams make your own route (home – work – Bar – Anastasia – a house, or in reverse order), watch it on one screen, edit, add or remove cameras.

A cursory glance at the map we can estimate the total urban situation, as each camera on the site every 5 minutes assesses the road and painted in different colors – from green to red. Free, stickjaw, congestion, accident. And while drivers, and use other verbs and adjectives in the definitions, it is still very comfortable and in comparison with other reference services objectively. The next fundamental news. If you involved in an accident in the area of the web camera, you can order the video for this period. How it will come in handy as an extra dokazuhi – it is a legal issue, but still a major breakthrough in the XXI century. The site reports that the best make an order within 2 days after the accident. In practice, the infa stored longer – up to three days. A significant accident admins hang out in the news. Finding Your movie will do for free. Still there is a mobile version of the site. Rate Work will be smaller, but you can still look in the right chamber and sitting behind the wheel. The site "Videoprobki" useful not only for motorists but also to anyone who wants to see the weather in Kiev, because meteorologists are often wrong. But in the main window site, you can watch Live TV from the streets and their own eyes to evaluate the weather. In general, useful project! It remains to wish the project the development of the whole Ukraine!

Xenon Lamps

The standard halogen lamp – a thing not a capricious and budget, but the quality of coverage often leaves much to be desired. Going at speed, and tired eyes peer into the darkness. This situation can and must change radically. Assistant in this case – xenon headlights. It has many advantages, and most importantly – that it glow better perceived by the human eye.

This fact is well known, do not live in the Stone Age. Xenon light source such as HID (High Intensity Discharge) – a discharge lamp, filled with a mixture of noble gases including Xenon. The principle of the lamp is as follows. At the initial ignition of the lamp electrodes to its hazardous voltages and under the influence of electromagnetic fields in the bulb starts the process of ionization of the particles to form a gas-discharge arc. After that is required to maintain the arc voltage is reduced to about 80 volts.

In the laboratory, and tuning Design Car-Lab you can buy a kit xenon light for 3000 rubles! It includes: * 2 lamps, 2 blocks * Ignition * connecting wires and brackets. The main characteristics of a xenon lamp: 35W input power consumption voltage 12V Color temperature 4300K (yellow) 5000K (white), 6000K (white-blue); 8000K (bluish) In contrast to halogen lamps with xenon lamps instead of incandescent spiral built two electrodes, which are immobile condition. At a certain distance from each other in full of gas and metal salts of gas charging tube of quartz glass. With gas high-voltage pulse between the two electrodes is electrically conductive and an electrical discharge occurs. So called xenon lamps as lamps, gas discharge. The electrons move between the electrodes and electrically charged gas in such a way that the energy manifested in the form of light. The color temperature of an electric discharge is determined by some mixture of gases and mixtures of metal which are used with these xenon bulbs. Choice of color is based on gas used. HID xenon lamp radiation, the emitted spectrum is closest to the sun the light of day. The result is a bright light and less eye fatigue when driving at the dark. Xenon bulbs are twice as high intensity light beam compared to classical halogen, at a much lower current consumption. In addition, they surely will allocate your car among hundreds of others. Xenon lamps can be used in the headlights near, far and fog light without replacing the standard wiring. Currently, xenon lamps are available with virtually all the most common caps: H1, H3, H4, H7, H8, H9, H11, H13, H27, 9004 (NV2), 9005 (HB3), 9006 (HB4), 9007 (HB5), D2R, D2S. The advantages of xenon bulbs in comparison with halogen: * big light output due to higher (by a factor of 2-3) the relation of power to the power flux energy consumption, which provides almost double the illumination of the road in the dark * much longer life (1000-2500 instead of 300-500 hours) * large economy (35W instead of 55-100W) * stability flux, regardless of possible fluctuations of voltage the car * greater comfort due to excellent visibility of the road at night and in adverse weather conditions, which allows the driver to get rid of undue stress, vibration resistance * (no filament) * lower heating temperature.
