Chapter 696

"OK, director Sun! Don't be so critical, tell me about its performance Thunder day Tang smiles to urge a way.

"Good boss! This supersonic private aircraft with internal code C1 in our laboratory is 59 meters long, 7.6 meters high and 23 meters wingspan. The designed carrying capacity of the aircraft is 18 people. I think this kind of capacity is enough for both the boss and the high-level use of the company in the future.

The luggage compartment can carry 8 tons of luggage. In addition, we have specially designed the luggage compartment of the plane. Even if the boss wants to carry a sports car, he can drive in!

The whole fuselage adopts a large number of high-strength lightweight alloy materials of the company, which makes the aircraft not only lighter in weight, but also particularly strong in fuselage strength, which is the biggest guarantee that it can fly at supersonic speed!

Using two SW-1 super engines designed by our laboratory, we can make its cruise speed reach Mach 2.2, and the maximum flight speed can reach Mach 2.8. Even if the cruise speed is flying, it will take about 4 hours to fly from Helei to Boston at his speed of 2695 km / h!

And because our engine also uses our company's high-performance materials and brand-new intelligent fuel consumption control system, its fuel consumption is lower than that of ordinary aircraft, so if you fill up the fuel, the range can reach 13000 kilometers, which is enough for boss to fly from Hefei to any place in the world! "

"What?! How can it be so fast! " Lei Tiantang is really too surprised about the speed of the plane!

According to the latest data, the flight speed of Laomei's F-22 is 2410 kmh, which is quite remarkable, and is absolutely worthy of the remarkable life experience of the F-22. As the main combat equipment of the United States and the United States, the aircraft has been in service since 2005, and its "4S" standard is still the recognized standard and direction of fighters in the world.

The su-57 fighter plane of polar bear has a flying speed of about 2140 kmh. It is the only five generation fighter developed by the polar bear air force after the collapse of the Soviet Union. It integrates many advanced technologies of polar bear. Although suffering from economic difficulties, outdated equipment and backward electronic system, it is finally ready for service after unremitting efforts. Although the stealth performance of the aircraft is poor, its maneuverability is excellent.

And our j-20 is flying at 3430 kmh. The most characteristic canard aerodynamic configuration of the j-20 makes its super maneuverability most prominent in the same generation aircraft. Even if the j-20c was just released, his flight speed did not increase too much, and the flight speed was only 3900 km / h!

From the flying speed of the five most advanced aircrafts in the world, we can see how advanced the speed of the supersonic private plane designed by sun Changhe. Actually, it can reach the flight speed of a fighter!

You know, this is a civil aircraft! It is two concepts with fighter. Even from the aspect of volume, it can't be compared. The size of this private plane is at least two times larger than those fighters. Everyone knows that the bigger the aircraft wants to fly, the faster its engine performance needs to make a great breakthrough!

"My biggest expectation for you was to make it cruise at Mach 1.5, but I didn't expect you to give me an unexpected surprise." Lei Tiantang said happily.

"Boss, it is also inseparable from the company's support to achieve such a breakthrough. Without all kinds of high-performance materials provided by the company, the strength of the aircraft fuselage designed by us would not be enough. We should know that the requirements for the structure and strength of the aircraft fuselage to support supersonic flight are very high. If this problem can not be solved, no matter how good our design is!

The design of our engine also uses the company's high-performance materials, which makes the engine lighter, but also can withstand the pressure brought by higher speed. This makes our engine power stronger than those used in fighter planes, and only such a strong power system can make the aircraft maintain such high-speed cruise flight! " Sun Changhe explained with a smile.

To tell you the truth, he and his colleagues in the laboratory are very satisfied with their own design. You know, this is a civil aircraft, and it is a luxury private aircraft. They are proud to design its performance to such a level that competitors despair!

With the development of supersonic flight, many aircraft manufacturing companies in the world have begun to invest a lot of energy in supersonic private aircraft.

One of the most famous is aerion's as2 supersonic private jet, which has received extensive attention since its release.

However, according to aerion, the maximum speed of as2 is only Mach 1.5, and the cruise speed of Mach 0.95 can reach the maximum range of 4750 nautical miles. In addition, as2 can cruise without sonic boom at a speed between Mach 1.1 and Mach 1.2. In areas where supersonic flight is not allowed, the aircraft can also fly at Mach 0.99.

No matter in terms of flight speed or flight distance, the planes designed by sun Changhe will explode them. The gap may be as exaggerated as two generations!After all, at present, these supersonic private airplanes have not been able to solve all kinds of design problems. For example, the flight range is not enough, and the supersonic flight will make a huge noise, so they are not allowed to pass through the densely populated areas. If these problems are not solved, even if they are put into the market, the local tyrants will not have a strong desire to pay.

"Good! But we all know that aircraft noise is very loud when flying at supersonic speed. Have you solved this problem? " Lei Tiantang is also very concerned about this issue.

"It is impossible to solve this problem absolutely. However, we have optimized the causes of noise from many aspects. The aerodynamic shape of our aircraft has been modified after millions of simulation tests, so as to minimize the drag in supersonic flight.

In addition, we have specially designed the nose and wing to minimize the impact wave. The biggest source of loud noise is the engine. In this respect, we also optimized it in the design, and we also carried out a special design inside the engine shell, which can reduce the huge noise generated by the high-speed rotation of the engine.

Although the international community is still arguing about the noise standard of supersonic private aircraft, the noise level of our current design aircraft has been reduced to the standard of ordinary civil aircraft flight. Even if the standard set by them is stricter, we can still pass the standard! " Sun Changhe explained with a smile.
