The airworthiness test of large civilian passenger aircraft is not strict. Usually, the airworthiness safety test, the total time of various tests, requires at least five to six thousand hours of flight to complete, so if only one aircraft is used for testing, even if it is twenty times a day

After a four-hour flight, you won’t be able to get an airworthiness certificate for a year.

So today's test is just the first test of the Blue Sky Airliner.

Test some high-altitude cruise flight tests, engine restarts and other test items of the Blue Sky passenger aircraft.

Because large civil aviation aircraft normally cruise at an altitude of 8,000 to 12,000 meters. The advantages of flying at this altitude are high visibility, birds cannot fly here, high safety factor, etc.

The disadvantage is that at this altitude, the air is thin and the temperature is low, which poses a great challenge to the safety of the aircraft.

The high-altitude cruise flight test means that the Blue Sky Airliner flies continuously for more than ten hours at an altitude of 8,000 to 12,000 meters in the troposphere and stratosphere, completing the 12,000-mile cruising range of the Blue Sky Airliner in one go.

.

At the same time, in the troposphere or even the stratosphere where the air is thin, the aircraft engine is turned off and tested to see if it can be restarted smoothly.

This type of testing is still simple, and there are many destructive tests.

Such as aborted takeoff test.

When the plane was fully loaded, the takeoff was forced to be interrupted, and the plane was stopped using only the brakes to test whether the tires would be damaged and leak, and whether the plane's brake discs would rub on fire and burn the plane.

In addition to these, there are also tailing tests, extreme weather tests, bird strike tests, lightning strike tests, etc.

These harsh tests are not only for the safety of passengers, but also needless to say, they are also high thresholds set by the two aircraft companies, Sonic and Airbus, to reduce competition.

Of course, this is understandable. After all, safety comes first. With hundreds of passengers on board, no matter how safe it is, it cannot be too safe.

At four o'clock in the afternoon, a burst of applause suddenly broke out from the control tower.

Because from the morning test to now, the Blue Sky Airliner has been flying continuously at high altitude for ten hours, which is close to more than half of the cruise test, and all the monitored data are perfect. Many items such as engine restart test, limit increase and so on have been successfully passed.

All in all, everything about Blue Sky Airliner performed perfectly.

Xia Yang was not surprised. As the chief engineer of the space battleship, Ed, it was no small feat to build an aircraft that could only fly within the atmosphere and pass these simple tests.

At this point in the test, Lawson couldn't stay any longer. At the same time, he was relieved and believed that the Blue Sky passenger aircraft manufactured by Xiayang could pass the demanding airworthiness tests in Europe and the United States.

Say hello to Xia Yang, say goodbye and leave.

After Lawson left, David came over with a smile on his face and said, "Mr. Xia, your blue sky aircraft performed perfectly, especially in the test links such as limit increase and engine restart. The performance was very exciting. The aircraft always performed smoothly and smoothly.

In my opinion, it is better and more stable than sonic aircraft, so I think I can place an order. I promised ten orders before, and I will place an additional order for ten more, for a total of twenty orders. My only request is that I can receive it as soon as possible.

Before you obtain European and American airworthiness licenses for these aircraft, I will not be able to fly on international routes for the time being. I can fly on domestic regional routes."

David winked at Xia Yang humorously.

After all, he is the boss of the airline company and has a ruthless vision. Although Blue Sky Aircraft has only passed a few test items, David has already seen its excellence and excellent quality.

At the same time, it is the local airline of Spur, which expressed its strong support.

The Spur Aviation Administration will not make things too difficult for the locally manufactured Blue Sky Aircraft. I believe that after another month of testing, it should be no problem to allow the Blue Sky Aircraft to fly short-distance regional flights.

"Thank you David for your support. I have asked Ed to start mass production of Blue Sky aircraft and added five production workshops. Soon our Laisuo aircraft factory will have six state-of-the-art aircraft manufacturing workshops. I plan to produce the first batch of

The six Blue Sky aircraft will be used for airworthiness testing first, and the airworthiness license will be obtained as soon as possible. After that, the six aircraft production workshops will start to produce your order at full capacity. I think there will be no problem in delivering twenty Blue Sky aircraft by the end of November."

Xia Yang made a promise to David.

Because he was not sure how many orders there would be for Blue Sky Aircraft, Xia Yang was cautious and only opened six aircraft production workshops, otherwise the production speed would be faster.

You know, later generations of sound wave companies produced an airplane in less than ten hours.

"I'm looking forward to it. Aircraft manufacturing requires a lot of aluminum. I heard that Australia's aluminum is very good. We are also a Sper company. I think we should support it. What do you think, Mr. Xia?"

David asked Xia Yang with a smile.

Eighty percent of the materials used to manufacture civil aviation aircraft are aluminum, and on average each large passenger aircraft consumes nearly two hundred tons of aluminum.

Exchange of interests or mutual support, Xia Yang simply agreed to David's request.

"No problem, let Aluminum send the product for testing as soon as possible. As long as it meets our requirements, the order is not a problem. However, in order to ensure a stable supply of raw materials, I can only give Aluminum one-third of the order at most."

Even if the interests are exchanged, Xia Yang cannot give all orders to Aalco.

"I have to say that this is a very wise decision. I am glad that we have reached a consensus in terms of supporting each other, so I wish us a happy cooperation!"

David smiled more harmoniously, then shook hands with Xia Yang and said goodbye.

Later, Xia Yang paid attention to Haili and asked her to cooperate with the Spur Aviation Administration to test the Blue Sky aircraft, and then left the aircraft factory. Because it was almost time to get off work, she went directly back to Sakura Villa after work.

What he didn't know was that at night, when he was sleeping soundly with his arms around the fragrant and soft Kujo Chika, a fierce debate was going on in the parliament hall of the capital of Sper.

"Everyone, I believe you have all seen the report submitted by the Spur Aviation Administration today. The Blue Sky passenger aircraft manufactured by the Leso Aircraft Factory performed perfectly in the 37 safety tests today, especially the bird strike test. After such

After rigorous testing, the Giant Turbofan engine produced by the Lysol factory has been able to work stably, which completely proves that the Giant turbofan engine produced by the Lysol factory is a mature and excellent turbofan engine."

The short and fat Congressman Justin spoke eloquently to all the Congressmen present.

The bird strike test is also an extremely demanding test among airworthiness safety tests.

Because airplanes will encounter flocks of birds when flying, and an airplane hitting a flock of birds head-on is like hitting a bullet.

So this test simulates a passenger plane being hit by a flock of birds while flying at high speed.

The test method is very simple. Mount turkeys directly on the air cannon, and shoot the turkeys like bullets on the windshield and engine in front of the cabin of the aircraft. They are very dense, just like a real flock of birds, like dense bullets.

Crash on the plane.

During the test, the aircraft failed whether the front windshield was broken or the engine was damaged and stalled.

Obviously this requires the aircraft windshield to be strong enough, especially the aircraft engine, which requires the aircraft engine to be extremely excellent and of high quality in order to pass such a demanding test.

After hearing what Justin said, Lawson frowned and asked directly, "Justin, what do you want to say? I don't think you are praising the Laisuo factory, so just say it directly and don't show off your pity in front of us.

IQ, otherwise I will laugh at you rudely!"

Lawson's words immediately caused many people present to chuckle. Lawson and Justin are sworn enemies. This is something the whole world knows.

Maybe he was used to being ridiculed by Lawson, but Justin was not angry either. His fat white face remained expressionless and he said, "The Troll engine is a very excellent turbofan engine, so we need to have in-depth cooperation with the Laisuo factory.

To cultivate more aviation talents, President Tokaf of the University of Melbourne contacted me and expressed his interest in this. The power laboratory of the University of Melbourne is willing to cooperate in depth with the Lysol factory to jointly develop a better turbofan.

engine……."

With a puff, Lawson laughed out loud before Justin could finish speaking.
