Reborn Xiangjiang Tycoon Growth

The technology of ground-effect aircraft cannot be said to be very advanced, and the Soviet Union, China, Saudi Arabia and other countries are about to master it. It is entirely possible to exchange some good things with the Americans while they still have some value.

With the technological strength of Americans, it’s not that they can’t develop it. It’s just that the major American companies have not yet eliminated the rift between them and cannot pool their efforts together. Of course, it has a lot to do with the fact that they are all private companies and it is difficult to integrate them.

.The United States is also a country of immigrants and has too many camps.

This is also the reason why the United States has built several technology towns that have not yet been fully formed. It is estimated that the final result will not be very good, and may even become a joke.

The F-15 fighter jet; nicknamed: American Eagle, is a third-generation supersonic jet fighter of the United States Air Force.

The F-15 fighter jet adopts a tandem two-seater swept-wing aerodynamic layout, is equipped with two turbofan engines, and has high maneuverability combat capabilities. The aircraft has complete all-weather combat capabilities and can use advanced medium-range air-to-air missiles to destroy enemy aircraft.

It mainly carries out air superiority combat missions and develops air-ground combat modifications.

The F-15 fighter jet was developed by McDonnell Douglas in the United States. It was developed from the f-x program launched in 1962. McDonnell Douglas won the bid in 1969 and made its first test flight in July 1972. In 1974, the first mass-produced model was delivered to the US Air Force.

Used. In service for nearly 40 years, the total production number is more than 1,200, with dozens of modifications, exported to six countries. Participated in more than 100 wars, large and small, and shot down more than 100 enemy aircraft. In the early 21st century, F-22 fighter jets were successively used

replaced.

Even in later generations, the F-15 is still the most successful heavy-duty air superiority fighter. The combination of the F-15 Eagle and F-16 Fighting Falcon fighter jets is very successful and can be said to be the guarantee of the United States' foreign air supremacy.

McDonnell Douglas owns so many excellent military aircraft such as F-15, F-18, C-17, etc., but it was finally acquired by Boeing. I don’t know what McDonnell Jr. did. It is understandable to say that he is the number one loser in the United States.

.

For Americans at this time, the status of the F-15 is very important, and it is difficult to obtain it.

Due to its high price, in addition to the United States, the only countries that used it in the early days were Israel, Japan, and Saudi Arabia. Later, countries such as Singapore put forward procurement requirements. In addition, there are also F-15k based on the F-15e, sold to South Korea.

This is the first F-15 to use the GE engine. All previous F-15s used Pratt & Whitney engines.

At this time, Little Macdonald acted as the commentator and said to Bao Zixuan: "The F-15 fighter fuselage is an all-metal semi-monocoque structure. The fuselage is composed of front, middle and rear sections. The front section includes the head radar.

Cover, cockpit and electronic equipment compartment, the main structural material is aluminum alloy. The middle section is connected to the wing

, some use titanium alloy parts to bear large loads, accounting for about 20.4% of the weight of this section. The first three frames are aluminum alloy structures, and the last three frames are titanium alloy structures. The rear section is a titanium alloy structure engine compartment. The zigzag front edge

The horizontal tail is a fully moving horizontal tail with a large area that can meet the needs of high-speed flight and maneuvering.”

"The wing design adopts a tapered delta 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 in drag of the aircraft in the transonic speed zone more gentle, and the focus movement of the aircraft at transonic speeds is also smaller.

Reduces trim drag.”

"This is definitely the most advanced fighter jet in the world, and there is no one. As for the F-14 Panda fighter jet produced by Grumman, compared with it, it is still far behind."

"But this is an absolute secret of the U.S. Air Force. As a manufacturer, we don't dare to promise anything easily. I hope you can understand."

The American Eagle is not called for nothing, which is why old William would rather provide Heiyun with some production processes and details of the F-18 fighter jet, but dare not mention the F-15.

Bao Zixuan said with a smile: "Every company has its own difficulties, not to mention military products can never be decided by one company."

"This visit to McDonnell Douglas is really eye-opening. It seems that Heiyun Group still has a long way to go."

Little Macdonald replied: "You can't say that. Black Cloud is much better. At least the government will not interfere too much."

In fact, this is absolutely correct. The British would never have thought that the Heiyun Group in Xiangjiang would develop so fast. It is so fast that it is unbelievable, and at the same time, it feels not so real.

The previously signed bill stipulates that Hong Kong has strong autonomy in the commercial field and is a well-known international trade free port.

But that is only for ordinary commodities, and this also applies to the UK. Who would have thought that in the science and engineering desert of Xiangjiang, a company as outrageous as Heiyun could actually appear. Before the bill is revised, Heiyun Group can only be allowed to spread its influence to the world

Sell ​​weapons and equipment to any country.

Maybe Batumi can restrict it, but Xiangjiang is also within the embargo area of ​​high-end precision instruments in Batumi. Is it necessary to prevent other countries from transporting precision instruments to Xiangjiang, and at the same time prevent Heiyun Group from selling weapons and equipment, and mechanical equipment to Xiangjiang?

The scope of the ban depends on the country. There is no reason in the world, and people can completely ignore it.

Now Batumi is one head and two big, and I don’t know what to do. The ban bill is currently being revised to include Xiangjiang in the same treatment as the UK.

Bao Zixuan: "You own it after seeing it. I didn't say that I must bring the technical data of this aircraft back to Xiangjiang. Moreover, every company has core secrets, which are the capital of the company's survival."

"You can look elsewhere, McDonnell Douglas should have a lot of good stuff!"

A fighter-bomber similar to the Heiyun hh-01 Phantom fighter-bomber appeared in front of him, which surprised Bao Zixuan. Because according to historical development, this failed model should not have appeared.

The A-12 attack aircraft is a stealth attack aircraft jointly developed by McDonnell Douglas and General Dynamics. It is the first attack aircraft of the U.S. Navy designed to carry out long-range strike missions deep into enemy territory, and it is also the first

A stealth carrier-based aircraft invested and developed by the U.S. Navy. The U.S. Navy plans to replace the long-serving A

-6 Intruder attack aircraft, the U.S. Air Force also plans to purchase them to replace the F-111 Aardvark strike fighters that have been in service since the mid-1960s. However, due to budget overruns in the development plan, the weight of the aircraft and the development time

Due to problems such as Cheng Shunyan, in the 1990s, US Secretary of Defense Cheney announced the termination of the entire research and development plan.

The a-12 was originally planned to replace the a-6 attack aircraft in the mid-1990s. It used stealth technology that was said to be far more advanced than the Air Force's f-117a, and its payload capacity was also much greater than that of the "Nighthawk". Compared with the a-6e,

a-1

2 is faster, has a longer range, and can carry a large number of weapons in the internal bomb bay to reduce drag and maintain a low radar cross-section. Like the ATF, the A-12 is expected to be more reliable than existing aircraft

efficiency while requiring only half the maintenance man-hours.

In terms of specific indicators, in addition to requiring good stealth performance, the A-12 is also required to have a combat radius 60% larger than the A-6e, a 40% higher bomb load, low-altitude horizontal acceleration performance, instantaneous hovering angular velocity and maximum hovering

The angular speed is better than a-6e. Even the maximum circling angular speed

The speed should be equivalent to or better than that of the F-18c. When attacking the ground, calculated based on the area of ​​the target surface relative to the 23mm anti-aircraft gun explosive bomb, it should be equivalent to the A-10 or only 1/ of the A-6e

12, 1/5 of f-18c.

McDonald Jr. said with a smile: "McDonnell Douglas and General Dynamics started developing stealth aircraft as early as 1981, but they were not in such a hurry at the time. It wasn't until they saw the great success of the Black Cloud hh-01 Phantom fighter bomber

, to speed up research and development.”

Hearing this, Bao Zixuan fully understood. At the same time, he also knew that it was because Heiyun owned the HH-01 Phantom combat bomber that Xiao MacDonald dared to bring him here. Ordinary partners are very worried about leaks, but they don't have so many scruples about Bao Zixuan.

.After all, Heiyun is already at the forefront of the world in terms of stealth bombers, and maybe he can even offer some valuable advice.

Bao Zixuan knew that the A-12 was troubled by the extensive use of composite materials in its structure. Composite materials did not achieve the expected weight reduction effect. Because they did not meet the requirements, some components had to be replaced by heavier metal parts.

.There are too many openings in the belly skin of the aircraft. The two wing beams bear a heavy load and must be reinforced with composite materials.

The material also needs to be specially thickened, and the improvement work is huge. The weight of the aircraft exceeds 30 tons, and the aircraft is already overweight by 3,630 kilograms, 30% overweight than expected, approaching the upper limit of the weight of aircraft carrier-based aircraft. In addition, the complex inverse synthetic aperture radar system is also

Encountering difficulties, the development of advanced avionics has been delayed across the board.

Like the DC-10 three-engine airliner, the A-12 project is destined to fail. However, Heiyun already has the hh-01, which is enough for now; McDonnell Douglas's A-12 is left to them to play with.

At the same time, I also somewhat understand the reason why McDonald's hand of good cards is so bad. There are so many failed projects, and the money earned by the F-15 and F-18 is not enough to invest in them.

After that, Bao Zixuan visited the production lines of F-18, A-4 and other aircraft, which gave him a comprehensive understanding of McDonnell Douglas. At the same time, he was shocked by the heritage of American aircraft manufacturing companies.

If an acquired McDonnell Douglas can do this, then what will happen to the more powerful Boeing, Lockheed, Pratt & Whitney, and General Dynamics? It is simply unimaginable.
