TRX concept, Stealth Aircraft Future United States

TRX concept, Stealth Aircraft Future United States

Do you know the U-2, a spy plane USA famous and will soon be disabled? U-2 spy plane is capable of flying at an altitude of more than 70 thousand feet! Dragon Fly is his nickname, described the aircraft as a flying dragon is ready to appear on any area in the world without bias detected by enemy radar. U-2 was going to retire, but its successor is being prepared Lockheed Martin and be ready to operate in 2025. TRX, name spy plane future of the United States. The aircraft is designed not only doing a spy mission, but also capable of electronic warfare and equipped with laser-based weapons system!

Just like U-2, TRX was designed to fly at an altitude of 70 thousand feet and may also use the F118 engine, the same as that used by the U-2. According to rumors, the appearance of both types of aircraft that are relatively the same, but as mentioned above, TRX equipped with the latest technology, one of which is the ability to coordinate with the various NATO warplanes. To be sure, the TRX is more “stealth” than the U-2. Americans have learned from the experience of 1960 and 1962 when a U-2 plane shot hanud Soviet artillery. A modern spy plane is not enough just to rely on spectacular heights because of the latest types of missiles are already capable of reaching it. A spy plane must be very-very modern “stealth”.

Each technology development requires substantial funds, not least the development of TRX. Researchers from Lockheed Martin puzzled by increasing the amount of funds that may be required. It is recognized by Lt. Gen. Robert Otto, a high-ranking United States, that the US government might not be enough funds to combine the capabilities of the two best high-altitude platform, became the main characteristics of the TRX. High-altitude aircraft platform is designed to have extra capacity, for example, capable of flying at an altitude of 70 thousand feet for hours or even days. Two of the best high-altitude platform in question is a U-2 spy planes and Global Hawk. Both of the plane has a number of extra features are hard to match by other military aircraft. Well, TRX is designed for improved U-2 and Global Hawk.

What are the advantages of U-2 prominent enough? In general, the U-2 is able to fly very high and can only be intercepted by Mig 25 Russia capable of flying up to 123 thousand feet. While the Global Hawk is able to fly up to 30 hours and serve as satellites and aircraft at once. Global Hawk aircraft were able to observe the atmosphere in remote areas, such as the Arctic and Antarctic. Global Hawk air transport capacity could reach 500 kg which usually consists of various scientific instruments. Altitude, flight duration, haulage, super reconnaissance sensors are some of the important characteristics needed by a modern reconnaissance aircraft, and all of which are designed to be transplanted in a plane alone, TRX!

How to Calculate Boiler Efficiency

How to Calculate Boiler Efficiency

Boiler efficiency is a quantity that indicates the relationship between input energy entering the boiler with output energy produced by the boiler. However, the efficiency of the boiler can be defined in three ways:

  1. Combustion Efficiency
  2. Thermal Efficiency
  3. Fuel-Efficiency Steam (Fuel-to-Steam)

Combustion boiler efficiency generally describes the ability of a burner to burn the entire fuel into the boiler combustion chamber (furnace). The efficiency of this type is calculated from the amount of fuel that does not burn along with the amount of air combustion air (air excess). Burning boiler can be said to be efficient if there is no remaining fuel in the end outlet of boiler combustion chamber, so does the number of residual air.
To obtain high combustion efficiency, burner and boiler combustion chamber must be designed as optimal as possible. On the other hand differences in the use of fuels also affect the efficiency of combustion. It is known that liquid fuel and gas (LNG and HSD) produce higher combustion efficiency than solid fuels such as coal.

The only difficult thing in calculating the combustion efficiency is how to pursuit the optimal number. Combustion efficiency is characterized by the overall fuel burning in the combustion chamber. While the control parameters are used to ensure the overall fuel burning, is the amount of air combustion (air excess) coming out through the stack. The more the amount of air excess coming out through the chimney, then the more likely the amount of unburned fuel can pass through the chimney. But you should remember that the more the amount of excess water passing through the chimney, the amount of heat energy escaping the rest of airborne is also growing. Therefore there is an optimum number of excess amounts of air, so that the boiler combustion efficiency can obtain the most optimal number.

Appears in the graph illustration above that the higher the amount of air (oxygen) passing through the stack, the smaller amount of fuel including carbon monoxide burned imperfectly. But as we have discussed above, the higher the amount of air excess, so the combustion efficiency chart is going to go back down, since the heat energy was coming away with the rest of the air. Then certainly there is an optimum value of the air excess to obtain the best combustion efficiency. As an illustration, the optimum value of air excess to the combustion of natural gas is 5 to 10%, liquid fuel at the rate of 5 to 20%, and 15 to 60% for coal combustion. Continue reading

History of Invention Electron

History of Invention Electron

Until now, there are a variety of subatomic particles that have been discovered by scientists. However, the discovery of the electron is considered to be an important chapter in the history of the study of subatomic particles. Even now, when we realized there were nearly 70 parts or more atoms, the discovery of the electron, proton and neutron, regarded as the foundation for further research into subatomic particles.

Electrons can not be found for granted. There are several scientists whose work is a pioneer in the discovery of the electron. Here are four scientists who played a phenomenal role in laying the discovery of the electron.

1. Johann Wilhelm Hittorf

In 1869, a German physicist, John Wilhelm Hittorf through research on electrical conductivity in a gas cylinder found that the strong light emitted from the cathode plate depends on the gas pressure.

2. Eugen Goldstein

In 1876, German physicist discovered that the light emitted from the light on previous experiments performed by John Wilhelm cast a shadow if an object is placed behind him. He was named as the cathode-ray beam.

3. William Crookes

In the 1870s, English physicist and chemist William Crookes makes cathode ray tube first to trigger the development of the theory for the existence of negatively charged particles in the beam being deflected from the anode to the cathode.

4. Arthur Schuster

The German-born British physicist continue work Crooke and more convinced that cathode rays have negatively charged particles. Continue reading

Know the History of X-ray scanning

Know the History of X-ray scanning

The ability to see through a variety of objects has long been a dream of various people. The dream became a reality after the discovery of X-ray machines are mainly used in medical applications. X-ray machine has undoubtedly saved many people with health problems are impossible to detect without the presence of this machine.

X-rays are actually an electromagnetic radiation carries energy, which is absorbed by some substances but not by other substances. One example is the use of X-rays to diagnose a fracture. In this procedure, the X-ray radiation is projected on the body of fractures. X-ray machines will fire photons that penetrate the body and partly absorbed by the bone. Photons that are not absorbed then caught on film that shows images and their bones broken or cracked happened.

In addition to the health sector, the X-ray scanning is also widely used in other fields such as to scan the luggage of passengers at the airport, or search for dangerous objects hidden like bombs or firearms.In November 1895, Wilhelm Rontgen, a German professor of physics discovered X-rays in examining the Crookes tube (tube containing gas to study the electron). Inadvertently, after wrapping a thin tube with black cardboard, he saw that some light make it through the cardboard. Upon further investigation, Rontgen discovered that these rays can pass through paper, books, and even his wife’s hand.

Images produced from bones of her hand printed complete with a ring she was wearing. This photo is credited as an X-ray image of the first part of the human body. Since then, the X-ray technology is growing. Two scientists who made a large contribution in the development of X-ray is Nikola Tesla and Thomas Edison that makes scanning X-rays into a standard procedure in modern hospitals.

In the early 1920s, it was realized that the use of Crookes tubes can not be relied upon again. To generate a current, the tube should be partially filled with a gas, which would be absorbed by the glass and eventually lead to the emission of X-rays that are not optimal. Crookes tube was also considered inefficient because it must always be replaced after a fire. This condition then encourages the Coolidge tube that uses a filament of tungsten and heated by an electric current. Coolidge tube is much more efficient than the Crookes tube and is still used in modern medicine and is the basis for most of the X-ray machine at the moment.

Being one of the most useful tools in the field of health, radiologist using a scanning X-rays to produce images of internal structures of the body of the patient. This allows various diagnoses such as broken bones, looking for the possibility of a tumor, and even saw the gastrointestinal tract can be done more accurately. By using the ‘space ion’ located between the patient and X-ray film, radiologists can adjust the amount of emitted radiation exposure to the patient.

Various types of X-ray machines are used for different applications. For example, the X-ray machine at the airport produces a very low radiation that is safe to use. As technology advances, the X-ray procedure also progressed. In the 1980s, the technology of X-ray laser was proposed but later abandoned because of the limitations of the current technology capabilities.However, the evolving technology allows the X-ray machine the future of smaller, less dangerous, and most importantly have the ability to scan better, so the potential to save more patients.

Underground storage innovation allows a country free from dependence on fossil fuels

Underground storage innovation allows a country free from dependence on fossil fuels

A recent study shows that wind energy, water, and sunlight could theoretically generate great energy at affordable prices if energy generation combined with generous storage. Over the past few years, a professor of civil and environmental engineering has produced a series of plans that are based on processing of a variety of data through computer models. That every state in the United States were able to switch to renewable energy and fossil energy left in total!

using the data needs of a wind power plant, water, and sunlight from every state. Assessing that every state is actually able to meet its energy needs with renewable energy as long as they combine it with cheap storage. Proposed a system that relies on the ability to store energy in an effort to provide energy at any time. For example, in the summer when the sun strikes with very high intensity, humans can store solar energy collected in solar energy collectors and use it to heat the house in winter. Plans also mentioned that hydrogen can be used as an energy storage medium; excess energy will be used to create hydrogen to be stored in fuel cells.

Underground storage as an inexpensive storage solution. Scientists led the demonstration of their proposal that the Drake Landing Solar Community in Canada. There, 52 homes heated during the winter with solar energy captured in the previous summer. Underground storage is cheaper than battery storage; only takes up half the cost of storage batteries. During this time many wind turbines can not handle the sudden demand for electrical energy for storage costs of wind energy are relatively expensive. With underground storage revolution, that the future of renewable energy will dominate the world and it will have a direct impact on the reduction of air pollution significantly.

Solar Panel Technology Revolution

Solar Panel Technology Revolution

A revolution in technology alternative back unsolved. A group of mechanics and scientists have announced that they will soon be marketing a new technology in producing solar panels. The technology they create does not require a complicated way to produce solar panels, all they need is a printer! Yes, a printing machine that will quickly and cheaply can print solar panels onto the surface of any object, especially plastic! Naturally this innovation will decisively, sooner or later, push down the price of conventional solar panels are quite expensive because the manufacturing process is more complicated.

Research conducted by a combination of mechanics and scientists have been done down at least the last few years. That this new technology can easily print solar panels directly on the sheet of plastic or other material. In fact, it can also be printed directly onto electronic equipment sorts of laptops and smartphones, so they get a renewable energy source at any time.

Print it out on a plastic sheet is approximately equal to the process of printing banknotes. Connect it with other electronic equipment as well as easy as installing the battery. It’s very cheap! The interface is also quite different from the conventional silicon solar panels. Elaborating that the printed solar panels will appear transparent, thus making it very suitable to be applied to building homes and buildings. The next task is to improve the efficiency of the panel. Should be able to create a ‘printing ink’ which is able to absorb more solar energy.

motorcycle

Many who thought that printing three-dimensional or 3D printing is limited to print a frame or bodyparts for medicalpurposes, but the 3D printing technology is now growing because the technology is able to print a motorcycle.

The motors are three-dimensionally molded the present thanks to Airbus, a subsidiary APWorks who successfully made the world’s first motorcycleproduced using 3D printing. But if the statement that made motorcycles APWorks was the first in the world?

Because motorcycles are printed using a 3D printing is something new, naturally when it was called the first. But actually at the beginning of this year, a man managed to scoreHonda CB500 motorcycle use 3D printing in 1972, but it was only a replica of which can not function like a real motorcycle.

Therefore, you will be able to figure out even further about what’s offered by the business and also the quality of the stuffs it offers. Now, the problem is related to the fact that online ecommerce method is quite vulnerable to the lack of communication between the buyer and the seller. If we are going to blame something for such situation, well, we can blame the fact that the buyer and seller don’t meet each other before they make transaction. Everything is done by using the operation of the system. The buyer checks out the webpage to see if there’s some stuff which can attract him or her to make the purchase. Once the stuff is found, the buyer add it to the cart and make the payment. The money is then transferred to the seller’s account. That’s it. It’s less humane indeed.

Some sellers try to solve such situation by adding a webpage specially designed to contact the sellers. However, normally, such solution doesn’t work immediately. It means that the buyers need to wait for a while before the sellers can respond to them. It’s not really that perfect as a solution. This kind of thing is quite troublesome as there are still many people out there who like to have such nice communication with the sellers. Having nice and convenient communication can also make it easier for the buyers to contact the sellers if there’s something wrong with the transaction. Well, the best solution for the situation mentioned above is actually to have chat tool integration with SuiteCRM. Yes, indeed, it is really true. Having live chat tool application on your website is going to solve everything.
