Beauty world

Detect roadside bombs, reconnaissance and foreign military, to launch a remote attack, the United States to show its mettle in various fields UAV, a national media darling of competing interest, but no one seems to borrow some unknown submarine, which is why? In fact, as early as the 1960s there have been no diving equipment, widely used in salvage, rescue, undersea exploration, anti-mine warfare and other areas, but because of the existing unmanned submarine life is short, displacement of small, difficult to implement for a long time , complex tasks, more limited military applications. But the pursuit of high-tech U.S. military always are trying to change this situation, trying to get future unmanned submarine as

According to the U.S. Navy But to achieve this plan, the first to break all kinds of technical problems.

Difficulty of finding the Holy Grail
comparable

According to information released by the Office of Naval Research, the envisaged large displacement of unmanned underwater vehicles (LDUUV) will be a completely self-control, long life, fired from the shore, to activities in shallow water unmanned underwater vehicle . Its diameter is greater than 36 inches (about 91 cm), the displacement of about 20,000 pounds (9 tons), endurance of 70 days or more, through the configuration of different equipment, to perform for a long time intelligence, surveillance and reconnaissance missions, the long voyage marine surveying, perform explosive ordnance disposal, mine warfare, anti-submarine warfare missions.

However, to achieve the performance required by the Navy, requires sophisticated new technologies that may also exist only in the inventor’s imagination, potential contractors and technical experts often develop large-scale unmanned submarine compared to the ancient knights seeking the Holy Grail legend – a great and difficult task, no one has seen the way the Holy Grail, no one knows where the Holy Grail. According to Second, how to avoid the water, water, underwater obstacles, automatic navigation?

Introduction of new energy technologies for sustainable power

The biggest problem is how to provide the ideal large-scale unmanned submarine force. Navy requirements for a lot of power systems, such as air-independent, durable, safety, environmental protection, small size, light weight, fast start, high performance. Rejected the first U.S. Navy nuclear-powered, the reason is very simple: in the event of an emergency situation, and no one on the boat, not in time, lead to disastrous consequences. In order to maintain the invisibility of unmanned submarines, will be a The traditional power system – battery simply can not meet the requirements of the Navy, because of its capacity can not meet the requirements of 70 days underwater. Hydrogen generator may be a good choice. U.S. Navy has with AlumiFuel Power Company (API) signed a contract to test hydrogen generator provides power for small submerged. Despite the potential of hydrogen in the energy sector is well known, but the pressure of hydrogen must be stored in the thick container, its not a small weight and size are large unmanned submarine will bring a lot of trouble. Perhaps there are other energy sources can provide sufficient power, but this time the U.S. Navy is evaluating designs submitted by various agencies, the parties have refused to disclose details. Robert Novak, according to independent analysts speculated that the final design may use a hybrid system. At low speed, low power requirements for use of battery-powered; need to improve the speed, through the switching device to switch to another energy system. Navy to reduce the demand for energy, also called unmanned submarines and other systems must be energy efficient.

No high-level U.S. Navy submarine force attaches great importance to the issue that can not be found to meet the requirements if the driving force, large unmanned submarines will not be able to complete its task. Just retired last September, Chief of Naval Operations Admiral Gary Roughead is very concerned about this issue. Last August, in the absence of aircraft systems, speaking at international conferences, he said: He put the past five years in the Navy’s research and development budget into half power operated vehicle to resolve the issue. In 2012, the U.S. Navy plans to invest $ 47 million for the development of large-scale unmanned submarine.

To avoid the reef and fishing nets for automatic navigation

Solve the power problem, does not mean that to find the Holy Grail. Unmanned submarines, unmanned navigation control complex than I do not know how many times. Tuna robots (Bluefin Robotics) Jeff Smith, director of the company’s major research project no automatic control of the submarine, he said: Our unmanned aircraft has been very clever, but in environmental awareness, the ability of these machines will never be close to the dolphins or seals. . In addition, because radio waves spread in the deep ocean is difficult, shore staff can not control the activities of unmanned underwater submarine establish a rapid and efficient communication, can not be real-time control. Therefore, controlling unmanned submarines, unmanned aircraft is not yet as simple as control. In 2008, a British company of an autonomous unmanned submarine fault occurs in the trials, is still missing. Therefore, the automatic unmanned submarine navigation is particularly important.

U.S. unmanned submarine is certainly the future cost of money, will involve a lot of secrets. U.S. unmanned submarine do not want to own by foreign fishermen, groan, or rocks being captured, or lost control of nowhere to be found, so the automatic navigation of a very high demand. First, large-scale unmanned submarine to within 70 days of the voyage, in accordance with the provisions of the planned arrival of 40 waypoints, waypoint arrival time of each error in 5 hours, distance error of 50 meters. This is not easy, because no one submarine in the water can not accept the GPS signal, difficult to accurately timing and positioning. Secondly, the undersea submarine to be able to find all diameter greater than 6 inches (15 cm) obstacles; sailing on the water or near water, and found two sea miles in all probability the surface vessel to reach 99.9%; found 100 feet (about 30.5 meters) in fishing nets more than 80% probability, and the ability to bypass the net. Again, also the activities of vessels under the surface characteristics determine the type of fishing vessels, warships, cruise ships, or merchant, and automated control of complex algorithms to determine the different circumstances of the motor way.

Even if the power problem and automatic navigation issues are resolved, it does not mean that everything is all right. Sufficient power can not ensure long-lasting life, such as submarine navigation in the long process, the hull will be attached to a large number of aquatic organisms, increased hull resistance, reduce speed. Temperature control is also important, no one submarine boat thanks to the computer control, how to prevent the computer from overheating, also a difficult problem.

League of Arab States (LAS) Mission operations in Syria is not over, disclosure requirements of the proposed military intervention in Syria has been released.

Arab League Secretary General Arabi, 15, said the Arab League ministerial meeting this week to discuss Qatar may be submitted prior to the Arab League to send troops to the Syrian proposal. This is also the Arab League for the first time hinted that it might intervene militarily against Syria.

Qatar initiated the

Emir of Qatar (that is, the country’s national leader) and Defense Minister and Armed Forces Hamad Bin Khalifa al-Thani 15 in the CBS broadcast of the program stunned: Syria sent troops to support the Arab League, to prevent genocide!

Asked Hamad became the first Syrian Arab leaders to send troops. But he did not say how the military intervention in Syria, the Arab will be effective.

15, said a representative of the Arab League, Arab League has not yet received any official proposal to send troops stationed in Syria, saying both Arab and non Arab countries are neither agreement on military intervention in Syria. However, Al Jazeera, Qatar 16 Arab League Secretary General Arabi quoted as saying that the Arab League’s foreign ministers will formally discuss

Arabi 16 in Bahrain, said: discussion

According to the agreement with Syria, the Arab League, Arab League mission will continue until the 19th of this month, will observe the round up than the first official report submitted by the Arab League. Arab League will be held 19 or 20 members of the Ministerial Committee and the Foreign Ministers’ Meeting to discuss the report and assess whether Syria has complied with the commitment of the Arab League initiative and the Arab League to reach the latest position on Syria. Analysts pointed out that the full report is essential, directly related to the future direction of the situation in Syria.

Statement by Al-Jazeera, Hamad’s the occasion.

Last December, the Syrian government agreed to the Arab League Since then, the Arab League’s more than 200 national observers from entering Syria, and soon made a very positive on the Syrian government’s observations. This allows the Syrian opposition and considerable dissatisfaction in some countries, the United States and even accused the Arab League mission

But then a few days, there were several classification of domestic terrorist attacks, the situation rapidly deteriorated: two observers’ left out of anger killed, several injured in a foreign reporter … … the United States and Syria, this characterization of the opposition, said: >

In this context, has a huge influence on the Arab League in Qatar Prime Minister and Foreign Minister Sheikh Hamad Bin Jassim said the Arab League Mission in Syria . Subsequently, the U.S. media suggested that broadcast the Arab League heads of state of Qatar

Some analysts have pointed out that the classification of the Arab League since its presence in the domestic security situation deteriorating, there are some forces are trying to show through violence (or even terror) means Syria political situation will further muddy the water. Therefore, the Arab League mission, how to maintain objectivity in the Syrian position on the issue submitted to the guidance of a real report, remains a challenge.

United States and Europe pressing harder and harder
League dilemma

Although no one can measure this week’s Arab League ministerial level how the qualitative Syria, but for the Arab League, whether or not to send troops in Syria, will face a serious consequence.

Tunisian President Marzuki 16 point out how serious the consequences would be: Lebanon’s Hezbollah militia will be affected, the entire region could be as explosive as this is our concern and related parties.

Some analysts pointed out, if you do not send troops to the Arab League in the new Middle East will be worried about the influence of the pattern completely lost, because the Libyan war has to end by the NATO intervention in the new League lost its leading position in the Arab world.

Arab League Mission 19 this month submitted its first report on Syria observation. The United States and other Western countries, undoubtedly the most willing to see a one-sided condemnation of the regime of Bashar report.

United States and Europe had told Arab League criticized the activities of the Mission, and even threatened to This makes the Arab League are struggling because of the Arab League would like to resolve its internal framework of the Syrian crisis, to avoid external intervention in Arab affairs again. But the United States and Europe clearly do not intend to give this opportunity to the Arab League and rights.

Therefore, the Arab League now have to consider the However, once the troops really, they must fall Arabia fratricidal infamy.

Internal and external pressure surge Syria at stake

Throw in Qatar

In China, this month, before the classification of government has been Today, the Department of Defense Inspector General Hamad Mohammed had defected earlier this month, the night of 15 members Imad announced in the Arab television station from the Government. Analysts pointed out that senior government officials of President Bashar centrifuge is a major blow to the beginning.

The international community, UN Secretary General Ban Ki-15 in Beirut, Lebanon to further pressure to the Bashar regime, said: : stop the violence, stop killing your people!

Dongbing information stroboscopic multiple gearing up

Although NATO spokesman denied that NATO Romero 13 countries are secretly planning joint military action against Syria, but the Russian National Security Council Secretary Nikolai Patrushev previously disclosed, according to Russia to obtain intelligence, and part of NATO Arab countries have started to prepare for military intervention in Syria, the United States, Syria and the British special forces have been sneaked into contact with the opposition, to assess what weapons and equipment they need to get support, and began to consider the classification of the northern region to open NATO aircraft and other forces of the situation.

Israel Defense Forces Chief of Staff Gantz 10, told parliament that Israel is the downfall of Syrian President Bashar al-Assad and the Syrian Alawi refugees Bay Ruge Lan Heights preparation. Gantz said:

Gantz also said that Israel should be taking action against Damascus for Israel, do hedge the fight.

Republicans held the first primaries in Iowa, six election candidates, former Massachusetts Governor Mitt Romney supports the lead run

Evening local time, the United States with a population of only 300 million and an area less than 15 million square kilometers of small states – Iowa, will attract the nation, and the world’s attention. The same day, the U.S. Republican Party will be held here first presidential election primaries, which opened off the 2012 U.S. presidential election. Complexity of the U.S. presidential election process, will continue for nearly a year. After pre-selection process in the complex, the most important national elections will be held in November this year.

field representative to the meeting

3 night, six from the Republican Party’s presidential candidate will receive about 120,000 Iowa Republican supporters of the out of the state’s 28 representatives to participate is expected to be held in August at the Republican National Convention. The National Assembly will elect representatives to the Republican presidential candidate, and Democratic presidential candidates for the presidency race.

Although I am not directly elected, but the six Republican candidates, as long as win the most delegates supported, it is considered to win the state primaries. The bottom to win support from voters, is the most critical of all this.

Currently, support for the three leading candidates are former Massachusetts Governor Mitt Romney, Paul, Texas Congressman and former Pennsylvania Senator Santo Salem. There is also the former House Speaker Newt Gingrich, Texas Gov. Rick Perry, as well as Minnesota Rep. Bachmann election.

Former U.S. Ambassador Jon Huntsman has declared for the Republican presidential candidate’s campaign, but support for bottom, Huntsman has basically abandoned the Iowa campaign, fully prepare for the New Hampshire primaries.

Republican Party Democratic Party still hot

On the Republican side of intense pre-start, the Democrats remained silent. President Obama has sufficient time to prepare for the final battle, and the current Republican primaries, just as he provided a good opportunity to understand the opponent. The White House said on Tuesday, Obama will go to Ohio 4 local time, at a local high school speech on economic issues. Analysts believe that the 2012 development trend of the U.S. economy, whether Obama will be the key to re-election.

Like with the Republicans, Democrats also elected party in the state on behalf of the National Assembly, then elected by these representatives of the Democratic presidential candidate.

Republican

From a historical point of view, thanks to the final to win the majority of the Republican presidential candidate in Iowa and New Hampshire come out on top, so the results of the two extra Hampshire raised concerns.

View from the current poll, Romney, Paul and Santos Haslem ranked top three in Iowa, no accident, then, the winner from the three men produced. Romney because it has experience in 2008 election, Governor experience, plenty of campaign funds and a strong campaign team, etc., are considered likely to become the Republican Party, However, several changes in its policies, accused of

76-year-old Paul is the Republican Party Santo Haslem in some extreme positions on social issues also, such as strongly opposed to homosexuality and abortion.

In terms of the overall situation on the Republican primaries, Gingrich may have finally won. As an experienced politician, conservative policy advocates, superior eloquence and high-profile, Gingrich election in the last two months have sprung up everywhere. But he’s also a heavy historical burden, such as the two marriages ended because of affair, he was led to the closing, when the Speaker was forced to resign and so on.

For Obama, not scandals, no major policy mistakes, with a strong campaign team and fundraising advantage, and killed Osama bin Laden, through the He re-election a lot of extra points. But not as weak U.S. economy long-term change, it will drag on Obama’s election. Nevertheless, the Republican Party of

They offer a Chinese aircraft carrier to the world a clear picture , not only to meet people’s curiosity , but also allows us to analyze China’s aircraft carrier .

The article said that , in fact , China purchased from Ukraine in the hands of a ship China’s intention is to show the world that he has a powerful world-class naval power.

The article said , it is worth noting that almost no country has a real sense of the full-scale aircraft carrier ( the U.S. has 10 ) . Moreover, the U.S. strategic analysts predicted Roger – Becker said,

The article said that , of course ,

The article said , Who would have thought China’s next aircraft carrier will be equipped with what weapons ? Becker said that China can not only build an aircraft carrier ; because , at least three aircraft carriers to ensure there is always a carrier can be used in combat ; and China to achieve this goal , take a very long time.

The article said that China’s aircraft carrier , once completed, is the real hard work to begin. Training can command aircraft carrier battle group operations officer , will take a generation or longer . Also precisely because of this , the former U.S. Navy commander was not on concerns about China ‘s aircraft carrier construction ; recent Pentagon report on China’s military development without any special warning
