Chapter 1743

At that time, Qin Guan said that the three passenger planes were unsafe, but he didn't say how it was unsafe. Now, we can finally give them a serious analysis.

"Douglas's DC-10 is a completely immature emergency product from the beginning of its design. At that time, in order to seize the market, they needed a long-range jet with less passenger capacity than Boeing 747, but a range similar to Boeing 747, and more importantly, it can directly use most of the existing airports in the world at that time. Douglas's DC-10, originally Only two engines were suspended under the wing, but the thrust was not large enough to take off and land on the runway, and the safety was not enough. Therefore, they adopted the simplest method. "

Qin Guan knows the origin of this plane clearly. Now, it's time for the world to know. There are too many tricks in it!

"If you add another engine, the takeoff and landing performance will be good. However, if you directly add it, it will bring a lot of detailed modifications to the aircraft and make them invest more. For a capitalist, mercenary is their fundamental goal. They will never be people-oriented. They only value interests and the smaller the investment, the better. Therefore, their designers adopted it The simplest way is to add an engine at the root of the vertical tail of the airliner. Such design changes have many advantages. The biggest advantage is that the whole rear fuselage does not need to make too much design changes. The investment is minimized. "

Qin Guan's words are quite powerful. They just want to make money by all means and ignore life!

"However, the biggest problem with this design is the poor handling performance and the unstable thrust! Our previous three engine airliners were all at the tail, and there are rarely three engines that are not on the same plane. There are two engines under the wing and one behind the fuselage. The thrust of such engines is not on the same plane. Although the power is enough, it is biased The rotating torque is very large, and it is very difficult to mediate. This design reason is the most fundamental problem of frequent DC-10 crashes! "

Point the source of the crash to the third release Bureau, that is, there is no solution. If it is changed to two engines, the thrust is not enough, and four engines, what is the difference between them and Boeing 747? Why should customers buy them?

Their greatest confidence in those years was the layout of three releases. Now, in Qin Guan, the third release bureau is the culprit!

Then, the following is a map. The map on the top is obviously distorted when a DC-10 airliner landed! The wing on the left is almost touching the ground.

"See this picture? Every landing of the DC-10 airliner is so thrilling because of its poor handling stability and unstable center of gravity! Its design is irresponsible. Let's look at the historical records. Now, let's list the DC-10 air crash."

In 1972, Eagle Airlines flight 96 made an emergency landing and no one was killed.

In 1974, local chicken aviation, air crash, 346 people died.

In 1979, three air crashes killed more than 600 people.

In 1982, the takeoff failed and more than 50 people died.

In 1985, more than 200 people died on the white elephant flight!

These figures are bloody, innocent people died, and the final investigation has become an accident. However, we have not seen that among these accidents, there is an obvious feature, that is, the original design of this aircraft is problematic, which is the root cause of the accident!

Douglas company's tackling key problems every time is in place. It describes these accidents as pilots' mistakes and tries to shirk responsibility. However, we should polish our eyes and have a look. Douglas DC-10 airliner is one of the most frequent and notorious airliners in the world!

"Your manuscript is so sharp," Lisa said to Qin Guan. "If old John sees it, he will have myocardial infarction immediately."

"Yes, so what we need to do now is to put this manuscript into various newspapers, media and magazines, and spread it on the Internet. In short, we are duty bound to comprehensively crack down on this airliner and maintain the stability of the world airliner market. This is for the safety of the civil aviation market all over the world."

Now, Lisa finally understands all Qin Guan's strategies. If no one incites the flames, Douglas company may escape the disaster. If this statement is popular now, no one will take Douglas company's airliner again, which is definitely a huge blow!

"But I still don't understand," Lisa continued. "In this way, Douglas company is bankrupt. It's a whole, and McDonnell Douglas company will go bankrupt. Should we buy the whole McDonnell Douglas company? Eagle people won't agree to do so."

Although they have a good relationship with eagle, they are different in ideology. They are wary of Han in many places. It is not easy for Han to eat McDonnell Douglas.

"Of course not," said Qin Guan "At first, Douglas company merged with McDonald company. Now, Douglas company is going bankrupt. They simply sell Douglas company. We only buy Douglas company, so the resistance will be much smaller. Moreover, we don't necessarily buy it wholly. As long as those shareholders spit out their shares, we will sell them With the lowest ticket price income, we become the largest shareholder of Douglas company, so we can control the company. Then, our yun10 airliner can be put into operation in Douglas company, and it will be easier to obtain the airworthiness certificate. "

It took a long time to get the airworthiness certificate of Yunshi, but for this piece of paper, it broke down a company. If the eagle people knew Qin Guan's trick, they didn't know if they would sigh.

Lisa sighed a little. Qin Guan's circle is too big!

All the spearheads of Qin Guan are pointing at the insecurity of the three engine airliner. Yunshi is a four engine airliner, which is not included here. In the future, Yunshi will be produced together with Douglas company and Huating company in China, which will also be brilliant quickly.

However, there will be new problems.

Yun10 has cost advantages in domestic production. If Douglas company is acquired to produce yun10, what is their competitiveness with Boeing 747? You know, DC-10 relies on three rounds to misplace competition!

"Therefore, our Yunshi still needs to be further improved. It focuses on low fuel consumption." Qin Guan said: "this is what all airlines value most."
