Metropolis: I am a technology tycoon

——-In the chapter posted yesterday, there was a mistake in one place. It should have been the Tianyi 480 passenger plane, but it was written as the Tianyi 380. It’s ok for everyone to know.

In fact, the engines of the large civil aviation aircraft purchased by Yanlong Kingdom from abroad have been tampered with. The engines must be overhauled or replaced after 1,000 hours of use.

The service life of an aerospace engine generally refers to the time between use after leaving the factory and the first overhaul.

The engines of large civil aviation aircraft produced by Pratt & Whitney of Eagle Federation will generally undergo the first overhaul after 10,000 hours of use.

After the first overhaul, the engine can continue to serve until it is completely replaced, which will basically be about ten years. The service life of the aircraft is only 20 years.

However, Yanlong Kingdom cannot manufacture its own aviation engines. The service life of the civil aviation passenger aircraft purchased from abroad is only 1,000 hours, which is one-tenth that of foreign countries. Every major repair or replacement of parts will cost you a lot of money from foreign companies.

The service life of the former Hongsu Empire’s civil aviation engines was only 1,500 hours, and the lifespan of military aviation engines was 500 to 600 hours, which was far inferior to the lifespan of the Eagle Federation’s military engines, which frequently reached more than 5,000 hours.

The operating costs of Yanlong Airlines are too high, which is why air tickets are so expensive.

After receiving the invitation letter from Galaxy Aviation Industry Group, the six major airlines in the country – East, South, West, North, Sea, and China – all sent their vice presidents to visit the large aircraft test.

For so many years, they have always been slaughtered by the Eagle Federation and the Kingdom of Ceylon. The top executives of the six major airlines are also very unhappy, but they have no choice. If they cannot build it themselves, they have to be controlled by others.

Receiving an invitation letter from Galaxy Aviation Industry Group this time is undoubtedly a very big surprise for the senior executives of the six major airlines.

Everyone in the City of Galaxy knows about it in Yanlong, and the major groups and companies under the City of Galaxy are all powerful and can be called leaders in various industries.

Now that Galaxy Aviation Industry Group claims to have built large aircraft and aero engines, even if it is not as good as the best foreign aircraft and engines, it is definitely better than the aircraft they are using now.

They are all their own people. As long as the performance of the aircraft meets the needs of their companies, the executives of the six major airlines are willing to spend more money.

Because there is a large airport in Galaxy City, the tests on the aircraft were placed at the airport in the east of Galaxy City.

After the vice presidents of the six major airlines led their teams to the Galaxy Airport, they saw four planes parked at the airport from a distance.

One of the aircraft is familiar to everyone, that is the Boyin 707 passenger aircraft, which is also the aircraft used by major airlines.

The other two aircraft are blue and white aircraft painted with the Galaxy logo and the Yanlong national flag logo. They look very pleasing to the eye and are two times larger than Boyin 707.

The last plane was very big, with the Galaxy logo and the Yanlong national flag painted on the fuselage, and it was more than twice the size of the Boyin 707 passenger plane.

“Hello, Director Lu””Lu Donghao””Hello, Mr. Lu.”

After seeing Lu Xingfan’s presence, the vice presidents of the six major airlines hurriedly stepped forward to say hello, and Lu Xingfan nodded in response.

After everyone arrived, Lu Xingfan didn’t waste any time and asked Huang Boqiang, the person in charge of Galaxy Aviation Industry Group, to I took everyone to visit the Tianyi 180 aircraft and Tianyi 480 aircraft first, and introduced them while visiting.

“This is the Tianyi 180 large passenger aircraft developed and built by our Galaxy Aviation Industry Group. The fuselage is 45 meters long, the wingspan is 44 meters, the height is 15 meters, the fuselage is 5 meters wide, the cockpit is 4.6 meters wide, and the cockpit is 2.8 meters high.

The cab has 3 pilot seats, can be equipped with two or three pilots, and has a passenger capacity of 180 people.

The Tianyi aircraft uses a new type of aluminum alloy developed by our Galaxy City Materials Laboratory, which is more than twice as strong and tougher than the MSF aluminum alloy used in the Boyin 707 aircraft, but weighs only four-fifths of the MSF aluminum alloy.

A stronger body and lighter weight. Although the Tianyi 180 is two times larger than the Boyin 707, its empty weight is almost the same.

The engine uses our independently developed Gale 12 large-bypass turbofan engine, which can provide a maximum thrust of 12 tons. The aircraft has a practical ceiling of 12,800 meters, a rolling distance of 2,400 meters, and a cruising speed of 0.9 times the speed of sound, which is 1,100 kilometers per hour. kilometer.

The maximum speed is 1.2 times the speed of sound, which is 1,460 kilometers per hour, and the maximum range after filling up with fuel is 6,400 kilometers.

Also, the Gale 12 turbofan engine has been tested for two years and has a service life of 10,000 hours. You can take a look at our engine test records later.”

After visiting the Tianyi 180 passenger aircraft, Huang Boqiang took everyone to visit the Tianyi 480 passenger aircraft.

“The Tianyi 480 intercontinental passenger aircraft has a fuselage length of 70 meters, a wingspan of 76 meters, a height of 24 meters, a fuselage width of 7 meters, a cockpit width of 6.4 meters, and a cockpit height of 3 meters.

The cab has 3 pilot seats and can be equipped with two or three pilots. It has a passenger capacity of 480 and a cargo capacity of up to 64 tons. It uses four Gale 30 turbofan engines, and a single unit can provide up to 30 tons of thrust.

The practical ceiling of the aircraft is 14,000 meters, the taxiing distance is 2,700 meters, the cruising speed is 0.9 times the speed of sound, and the maximum speed is 1.2 times the speed of sound. It is the same speed as the Tianyi 180 passenger aircraft. The maximum range of a full tank of fuel is 18,000 kilometers.”

After visiting the Tianyi 180 and Tianyi 480 passenger aircraft, people from the six major airlines were shocked by what Huang Boqiang said, and then they were overjoyed.

However, before they could discuss the price, Huang Boqiang waved his hand, and two people A man came over carrying a big wooden box. When he opened the wooden box, he saw that it was a machine gun and a grenade. Damn it, what are you doing? People from the six major airlines have questions in their minds!

Huang Boqiang faced the six major airlines Someone from the company said:”I just said that Tianyi 180 and Tianyi 480 are safe and very strong. But you can’t imagine how safe and strong it is. Let’s test it next.”

Holy crap! You brought out these machine guns and grenades just to test whether the aircraft is strong?! So hardcore?

People from the six major airlines are a little confused. They have never heard of such a hardcore thing in their lives. Test method, don’t say any nice words, just use grenades

“These are the current equipment of the Eagle Federation. If you are interested, you can try them out. After saying that, Huang Boqiang signaled the two security personnel to take action.

After Lu Xingfan nodded, one of the two security personnel held a light machine gun and the other held a grenade. They started testing with Boyin 707.

‘Da da da——’”boom——”

What was originally a good Boyin 707 passenger plane was immediately damaged by machine guns and grenades. A big hole was opened in the fuselage by a grenade.

After Boyin 707, there is Tianyi 180 passenger aircraft

“Da da da——”‘boom——’”boom——”

Under everyone’s shocked eyes, the machine gun bullets did not break the fuselage alloy of the Tianyi 180 extension, and it took two grenades in a row to explode the fuselage.

The next Tianyi 480 passenger plane used three grenades to finally explode the fuselage.

Good guy, the people from the six major airlines are completely convinced.
