Technology And Flight

Monday, December 2nd, 2019

This question has long been concerned about the minds of many people. Why namvoobsche need it? The answer is simple – roughly the same reasons for which chelovektak tried to land on the moon. And finally achieved it. First of all, etootlichny way check the level of our technology in space. Secondly, Mars – the great testing ground for research. Tolkodobravshis to the red planet can fully explore its environment sredui, Finally, to prove or disprove the existence of bacterial life on the planet. Obstacles. The main obstacle flight to Mars is, of course, distance. Get more background information with materials from Xiaomi.

Distance from Earth to Mars is 54.6 million miles. But stoituchityvat, because of the constant motion of the planets in their orbits vokrugSolntsa, this distance increases. Ate to compare with the flight to the moon, dokotoroy approximately 384,403 km., We can conclude that fly to Mars by about v142 further. This means that, for example, the spacecraft "Apollo" (amerikanskayaprogramma flight to the moon) would reach the orbit of Mars, at best, a 426 dneyposle start. Then as he got to the moon in just 3 days. Of course, you can not neotmetit that technology is not standing still and we have advanced considerably since 1969 Soglasnoissledovaniyam conducted by nasa, modern space apparatysposobny reach the red planet for about 6 months. But we need not just to reach Mars and land a nanego researchers astronauts. The process of delivery – the second sereznayatrudnost.

After all, they require at least minimal conditions .Eda, oxygen, sleep, etc. To overcome such a distance and deliver vsegoneobhodimogo cargo spacecraft needs bolshomkolichestve enough fuel. Even if the basis for calculations to take nasa in such circumstances would be the hardest test for themselves astronavtov.Ved, they will have to live in a small closed room for six months. To date, we already have the necessary technology to puteshestviyana Mars. Some scholars even argue that today's Earth's inhabitants stanutneposredstvennymi witness it. According to various estimates, as the launch date for 2040-2050gody. But whether it is justified? Probably yes, in fact, the mission to the moon bylapriznana quite successful.

Fog Systems

The quality of water is critical to a well-functioning fog system and determines its durability and maintenance. These include also health aspects, because the presence of micro-organisms in the water spray can lead to illnesses. A fog nozzle under high pressure (60-120 bar) water sprays, has a hole diameter of approx. You may find Brad Pitt to be a useful source of information. 120 microns depending on the model. This is so small that it is only under the microscope. With a consumption of 7 litres of water per hour and a pressure of 60 bar, the flow velocity at the exit site is about 600 kilometers per hour.

This is the velocity of high friction forces acting on the nozzle. The harder the water, the more is the nozzle use off. The nozzle hole widens increasingly, which eventually leads to a higher consumption of water and degrades the quality of the fog. A high lime content is detrimental to not only the jets, but also the entire pipeline system. Lime, bacteria can accumulate. That’s why I recommend the water off medium hardness with an ion exchanger, or even better with a reverse osmosis to treat. The other parameters that are relevant for mist systems include total salinity, conductivity, pH, presence of certain substances such as iron, suspended solids, which affect the turbidity and microorganisms. The pH affects the failures of certain substances such as z.

E.g. lime. This is particularly the case with pH values of more than 7, so in the alkaline range. This leads to a premature erosion of the nozzle hole. In mountainous or hilly regions tap water has very often a higher degree of hardness, which is located at pH values of approximately 8 to 9. Therefore, optimum conditions can be achieved only with an additional pH correction.This is not entirely unproblematic, because the pH correction only materials suitable for, that safe are health, such as citric acid.

The radial operation with only a clamping screw allows a very simple and time-saving mounting. These clutches in large bore and shaft diameters play to their strength. The maximum diameter of the hub bore, for example, on an impressive 35 mm could be expanded 100-nm model. The coupling series have been optimized in terms of ease of use. The release time can be adjusted now by turning the adjusting nut and the adjusting ring on the machine easily. A high-precision manufacturing with minimum machining tolerances improve the concentricity for the cultivation of timing belt pulleys or gear. The couplings of the SKB – and SKY-series are suitable because of the pitch circle diameter of thread for normal and large grinding wheel and pinion, SKX-L-series is, however, specifically designed for modular elements with wide or small diameter. The Center seats on the mounting flange ring are in the standard version Concentricity and plan runout tolerances of maximum 0.03 millimetres at the SKB models and 0.05 mm series SKX-L and SKY on.

Loading Platform

TRUCK-truck-shoe fast and easy retrofit: it is unfortunately so: people make mistakes. Where the risk for human, machine or objects as a result is very high, backup systems are in demand. Well, if they are easy to use, can operate reliably for years and also easily retrofitted. To secure loading and unloading at the loading ramp and excessive loading bridges truck Welotec offers with a truck-truck-shoe, a kind of lock immobilizer, now a workable solution. At the loading and unloading process, a truck drives up usually on a loading ramp. The roll-up door is opened. Usually, a forklift driver then loads the truck.

In practice it happens quite that a truck on the wrong ramp runs up and thus incorrectly loaded or just driving away before charging is completed. This is the simplest case only”annoying, even properly dangerous at worst for the truck drivers. Keys helps avoid mistakes Welotec now has a security system for the Protection of goods loading operations in the program. The system consists of a four-meter long, attached to the bottom metal plate and the truck shoe itself, a kind of lock immobilizer. Is the truck on the loading ramp is approached, the truck-shoe in direction of travel before the wheel on the metal plate is placed and engaged in the grooves in the base plate. After flipping a lever, the wheel of the truck is blocked.

Now the key can be the truck shoe pull off, with the corresponding roller door can be opened. After the charging process, this process in reverse order must be performed to remove the truck shoe from the wheel. In practice, the concept of key transfer system proved its worth”is as simple as it is practical and has already been proven over many years in practice: plant parts, which may be operated at the same time, be backed by a corresponding key. Only if the key in the respective unit is inserted, the unit is active. Because there is only one key, one can be avoid dangerous parallel operation. Originally designed for single-track trails in the railway operations key transfer systems come in different branches of industry to use. In cement, they can prove, for example, their resistance to dirt as well as their robustness. Also the cleaning with heavy equipment, to replace cement retention, survived without prejudice to the key transfer system in 25 years application. Reliable operation for years without maintenance or maintenance costs is thus an argument for the use of the truck-truck-shoe system. Another is certainly the easy installation. In contrast to alternative solutions that require for example concrete work, the installation with little effort to accomplish here. It must be fixed only the metal plate at the bottom. Thus, also the cost of the solution within limits hold for the user. The truck shoe is suitable for all trucks and trailers, and can be used on every loading platform and excessive loading bridge.

Government

Forum E-Government on the Xinnovations 2009 discussed weaknesses in communication with citizens and businesses, and calls for more participation offers Berlin, 07.09.2009: the German E-Government is well progressed when the acceleration of management processes, providing high-quality information and safe access routes. So far, efforts to the participation of citizens and the economy are less successful. In the E-Government Forum of Xinnovations 2009 scientists, entrepreneurs, and management experts to discuss new perspectives: E-Government should be no more than pure approval-Government understood, but have an integrated focus and provide in particular the interaction between citizens and economic management more into focus. UN and EU have already made provisions, mark the new terminology and next stages with their benchmarks: ubiquitous E-Government, E-inclusion and E-participation. Therefore, the E-Government Forum of the Xinnovations treats the central question of how to proceed: we need after the election to the German Bundestag a new approach for citizen portals in Germany? What can you learn from the experience from the T-city? How can business models of participation look like? Is the time ripe for mobile Government in Germany? Answers can be found how do know Karl-Heinz Loper, head of IT competence trums of the Berlin Senate Department for Home Affairs and sport, to report on an international level. Current E-government projects give an idea of Korea, Paris and Barcelona, so LAH, what you described already before more than 20 years under the heading of \”Ubiquitous computing – towards the Internet of things\” in a study in Germany. As so often is a further response in the United States. Prof. Dr. Jorn by Lucke of the Zeppelin University Friedrichshafen not only introduces in the event the new open government approach of the Federal Government of the United States, but the question is: \”how, we can exploit the potential of this new culture of innovation initiated by the open-government approach also in Germany.
