Supersonic Aircraft will Use Rocket Engine in the Future

It is said that the first supersonic aircraft of "Zehst" will come into use in 2050, and that will be the first supersonic airplane without any pollutions. While once this aircraft used in our live, we will only take half of two hours from Paris to Tokyo.

 

We've heard that this aircraft can bear passenger capacity of 50 to 100, and before the airplane fly, we should use the original biological fuel engine to promote it, and after it get to a certain height, we'll then change to use hydrogen and oxygen rocket engine to promote it, and its height will get to 32 kilometers that more over the height now.

 

When preparing to down land, this aircraft will turn off the engine, and then slipping slowly to the ground, it will restart the original engine when we get close to the earth surface.

The European Aircraft Company will cooperate with Japanese researchers to develop this new aircraft. Using existing technology to research and develop this supersonic aircraft, and they hope to be able to develop the prototype in 2020.

 

The developer said that: "We think that all aircrafts won't make any pollution just like Zehst. They can fly in the stratosphere all the time."

 

As we know, RC gasoline engine aircrafts will produce a lot of pollutions when flying in the sky. Pollutions caused by aircraft flying in the stratosphere are mainly from the burning of fuel exhaust, such as carbon dioxide, carbon monoxide, not burning hydrocarbons and particulate matter, nitrogen, etc. In addition, aircraft will also produce noise pollution. Condensation trail refers to the "white smoke" for the speed of flying. It is made by the water vapor in the air and exhaust fumes in the air condenses into ice crystals. Studies have found that condensation trail can form a roll cloud (a high-altitude cloud).This cloud will hinder the loss of heat radiation from the earth's surface, thereby contributing to global warming.

 

So the coming of the supersonic aircraft of "Zehst" will reduce the pollution produced by the airplane, and can also bring us a fresh environment. What's more, I also hope this model RC airplane of this mode will come soon.

American Retired Dentist turned to "Made" Model RC Engine Airplane

Isn't it wonderful model RC engine airplane can make only by the professionals?

Not yet. An American dentist who has made all of us surprise, he do not have any professional training before, only being interested in the model airplane and with full enthusiasm to devoted himself into the building of an model airplane, finally he has made out a model airplane with full metal.

Wonderful model RC engine airplane

Lie in the Joe Martin fund technology museum Vestas, California, there are an aluminum P - 51 D mustang fighter models sparkling among these lists: the Aircraft landing gear can free up, controller is working properly, ammunition stand on both sides, and we can see clearly about the inner structure of this airplane through the lift of the model. This airplane is made by Young, c. Parker who has spent over 6000 hours on doing it.

Parker, a 77 - years - old dentist, comes from Honolulu. Hawaii. Although he worked as a dentist for a living, he has a deep loving in model. Parker said that he likes to play the airplane in his early childhood, and he has tried to make all kinds of model airplanes from 6 years old.

He will never forget that the first time he saw a battle airplane, and it was in his 20 years old. At that time, he was serving in the army on the Korean battlefield. When Ricardo Carvalho brought him to a scrap heap of World War II aircraft, his enthusiasm for fighter aircraft is started from then.

After that, Paker spent most of his spare time to make a different model airplane including RC engine airplane and Rubber Band ejection airplane. At the same time, he groped continuously innovation, and tried to use aluminum as the model material, finally he has success made a pure aluminum model plane.

Parker said even though he like model, he does not want to be a famous man by doing that, and the success of him was all happened in chance. He said there are only a few friends who have seen his model airplane. While someday, a boss from a model club asked him to show his model airplane in an exhibition. He did not want to take part in for the first time, but the boss has registered for him without agreement from him. 

However, at that time, no one has produced the pure metal model yet, so the model from Paker has won a great praise, and the model also was given the calling of "The best metal model" by Joe Martin Fund.

Study Finds Danger in Using Laser Pointers Too Much

Are you still using laser pointers with high power? I think most of you do not strange to laser pointers, it is a little pen release a red or green light once you click it. We always used it when we making a PPT report and we need it to point out the key points what we are talking about. Or we may also be able to print some lovely picture in the wall by using them.

Presentation laser pointers have make our life more convenient, but there is some bad thing happened with the coming of this cool gadget.

For example, in the preliminary contest of European championship2011, England's player Tony Parker was into a disturbance by the laser pointer. And early in 2008, Lyon fans irradiated Cristiano Ronaldo's face with a laser pen for many times, so that has triggered strong protests from Manchester team.

However, there are still some people who use the laser pointer to harm the fly of the plane in the night. In fact, the dangerous of laser pointers are stronger than you though. Because once if the laser pointers was exposure in the pilots who driving absorbed, consequences cans be imagined; And take-off and landing stage itself is a high incidence of accident at that time, if the pilot encounter interference by the powerful light, the situation will become more dangerous.

Besides, laser pointers can also hurt our eyes without a good use. Looking into the laser power of 5 mw and above will cause temporary vision damage to eyesight; the more powerful will cause permanent eye damage or even blindness.

What's more, high power laser may ignite flammable and cause a fire. Some high power laser pointer, diffuse light may also cause harm to the eyes, focusing more likely fire on the flammable items.

But not all of the laser light source will cause harm to our eyes, once we've taken the appropriate protective measures, as long as there is some protection in the process of operation behavior, then this type of damage is very small. Here we suggest all of our friends to use laser pointers in a reasonable way to avoid hurting from it.

Safety Use of Laser Pointers

Laser pointers are usually applied in presentation situations for lectures, business conferences etc. to point at topics of interests. They are visible beams with various power output and changeable colors. Teachers can use it for teaching assistant and demonstrate their lectures vividly. And along with the advance of technology, laser pointers become more and more common in life. While one point need to concern is the safety use of laser pointers especially to human eyes.

This is a temporary optical problem concerning laser pointers with human eyes. Normal problems are flash blindness, glare and afterimages. Flash blindness occurs whenever someone is exposed to a bright light source. While it only lasts for a few seconds, it can be extremely dangerous when someone is involved in a task which requires vision, such as driving. Afterimages can last for several days, and take the form of small spots in the vision. Glare, a reduction of visibility caused by bright light, occurs while the laser is directed at the eyes.

Fortunately, there is no permanent damage to human eyes once harmed by laser pointers. They may cause reduction of visibility and one should use them carefully and properly to avoid dangerous. Moreover, there will be profound optical damages once under long time exposure of laser beams. Nowadays, many laser pointers are tagged as low harm or less power output, but there are still strong power ones. When it is focused on the retina through the lens of the eye, it can cause damage. Continuously staring into a laser through a fully diluted eye for over one minute may cause a retinal burn.

Many regions had regulated the labeling of laser pointers to ensure safety of users. One can find that there is a “caution” label on laser pointers to show their dangerous class and the power output are also showed. Many laser pointers are IIIA devices, meaning that there is a potential for damage with direct exposure to the laser. Class two lasers are less powerful, and are a better choice if you are concerned about safety. Usually, laser power within 1mW is relatively safety. They are mostly used as star pointers or teaching laser pens or just used to play with pets.

Generally laser pointer will not harmful to human if used properly. You cannot take it as a funny toy or just pointed directly at others. Even when you use it outdoors, you cannot just point it at random. Please do keep it away from children otherwise it may be dangerous as kids have little idea about the harm of laser pointers.
