Chapter 916 (1/2)
The technology of ground effect aircraft can not be said to be very advanced, and the Soviet Union, China, Saudi Arabia and other countries will soon master it. We can exchange some good things with Americans while there is still a little value.
With the scientific and technological strength of Americans, people are not unable to develop it. However, at present, the major companies in the United States have not eliminated their differences and can not concentrate their efforts together. Of course, they are all private enterprises, which has a lot to do with the difficulty of integration. The United States is an immigrant country with too many camps.
This is also the reason why several technology towns have not been fully formed in the United States. It is estimated that the final result will not be very good, or even become a joke.
F-15 fighter; Nickname: American Eagle, is the third generation supersonic jet fighter of the US air force.
The F-15 fighter adopts a tandem two seater swept wing aerodynamic layout and is equipped with two turbofan engines, with high maneuverability. The aircraft has perfect all-weather combat capability, can use advanced medium range air-to-air missiles to destroy enemy aircraft, mainly carry out air superiority combat tasks, and develop air-to-ground combat modifications.
The F-15 fighter was developed by McDonnell Douglas and developed from the F-X program launched in 1962. It won the bid by McDonnell Douglas in 1969. It was first tested in July 1972. In 1974, the first mass-produced fighter was delivered to the U.S. air force. It has been in service for more than 40 years, with a total production of more than 1200, dozens of modifications and exported to six countries. Took part in more than 100 wars and shot down more than 100 enemy aircraft. In the early 21st century, it was successively replaced by F-22 fighters.
Even in later generations, the F-15 is the most successful heavy air superiority fighter. The height matching of F-15 Eagle and F-16 Falcon fighters is very successful, which can be said to be the guarantee of the United States' foreign air control.
McDonnell Douglas has so many excellent military aircraft such as F-15, F-18 and C-17 that it was finally acquired by Boeing. I don't know what little MacDonald did. It's understandable to say that he is the first loser in the United States.
At this time, for Americans, the status of the F-15 is very important and it is difficult to get it.
Based on its high price, in addition to the United States, only Israel, Japan, Saudi Arabia and other countries used it in the early stage, followed by Singapore and other countries. In addition, there is the f-15k sold to Korea based on the F-15E, which is the first F-15 using GE engine. Before that, the F-15 used Pratt Whitney engine.
At this time, little MacDonald acted as a commentator and said to Bao Zixuan, ”the fuselage of F-15 fighter is an all metal semi hard shell structure, which is composed of front, middle and rear sections. The front section includes the head radome, cockpit and electronic equipment cabin, and the main structural material is aluminum alloy. The middle section is connected with the wing, and some titanium alloy parts are used to bear heavy load, accounting for about 20.4% of the weight of this section. The first three frames are aluminum alloy structure and the last three are titanium alloy structure. The rear section is a titanium alloy engine compartment. The flat tail of the serrated leading edge is a fully moving flat tail with a large area, which can meet the needs of high-speed flight and maneuver. ”
”The wing design adopts a truncated triangular wing shape, which can improve the wing structure and increase the internal volume of the aircraft. At the same time, it can make the increase of the aircraft's resistance in the transonic region more gentle, and the movement of the aircraft's focus in the transonic region is also small, reducing the trim resistance.”
”This is definitely the most advanced fighter in the world, and there is no one. As for the F-14 panda fighter produced by Grumman, it is still far from him. ”
”However, this is an absolute secret of the US air force. As a manufacturer, I dare not easily promise anything. I hope you can understand.”
The American Eagle is not barking in vain, which is why old William would rather provide black cloud with some production processes and details of F-18 fighters than mention F-15.
Bao Zixuan said with a smile, ”every company has its own difficulties. Moreover, military products have never been decided by a company.”
”Coming to McDonnell Douglas this time is really an eye opener. It seems that heiyun group still has a long way to go.”
Little MacDonald replied, ”I can't say that. Black clouds are much better. At least the government won't intervene excessively.”
In fact, this is true. The British would never have thought that the development of Xiangjiang black cloud group would be so fast. I can't believe it. At the same time, it doesn't seem so real.
