I have a little black hole

"Okay, Director Sun! Don't sell it, please tell me about its performance!" Lei Tiantang urged with a smile.

"Good boss! The supersonic private jet numbered C1 in our laboratory is 59 meters long, 7.6 meters high, and has a wingspan of 23 meters. The aircraft design capacity is 18 people. I think this capacity Whether it’s your boss’s use or future company’s high-level use is enough.

The weight of luggage that can be loaded in the luggage compartment can reach 8 tons. In addition, we have specially designed the luggage compartment of the aircraft, even if the boss wants to carry a sports car!

The entire fuselage uses a large number of the company's high-strength light alloy materials, making this aircraft not only lighter, but also the aircraft's fuselage is particularly strong, which is also the greatest guarantee for its supersonic flight!

Using two SW-1 super engines designed by our laboratory, it can make its cruising speed reach Mach 2.2, and the maximum flight speed can reach Mach 2.8. Even if it is flying at cruising speed, it will fly from Hefei at 2695 kilometers per hour. It only takes a little more than 4 hours to fly to Boston!

And because our engine also uses our company's high-performance materials and a new intelligent fuel consumption control system, its fuel consumption is lower than that of ordinary aircraft, so if it is filled with fuel once, its range can reach 13,000. Kilometers, enough for you to fly from Hefei to any place in the world!"

"What?! The speed is so fast!" Lei Tiantang was really surprised by the speed of the plane!

According to the latest data, the flight speed of the old and beautiful F-22 is 2410 kilometers per hour, which is quite remarkable, and it is absolutely worthy of the F-22's outstanding life.As the main battle equipment of Lao Mei's sophisticated technology, the aircraft has been in service since 2005. The "4S" standard it has established is still the standard and direction recognized by world fighters.

The polar bear's Su-57 fighter flight speed is about 2140 kilometers per hour. This aircraft is the only fifth-generation fighter developed by the Polar Bear Air Force after the disintegration of the Soviet Union. It integrates many advanced technologies of polar bears in one. Difficulties such as backward systems, but after unremitting efforts, finally to serve.Although the stealth performance of the aircraft is not good, but the maneuverability is very good.

Our J-20 flight speed is 3430 kilometers per hour.The J-20's most distinctive duck-type aerodynamic layout makes its super-maneuverability most prominent in the same generation.Even for the J-20C, which has just been announced, his flight speed has not increased much, and the flight speed has only reached 3900 kilometers per hour!

From the flight speeds of the world's most advanced 5th generation aircraft above, we can compare how advanced the flight speed of the supersonic private plane designed by Sun Changhe is, can actually reach the flight speed of fighter jets. Now!

You know, this is a civil aircraft!It is two concepts with a fighter, and even if it is completed in terms of volume, it is incomparable. The size of this private jet in front of it is at least more than twice that of those fighters. Everyone knows that the larger the plane wants to fly The faster the speed, then its engine performance must achieve a very big breakthrough!

"My original expectation for you was to make its cruise speed reach Mach 1.5. I didn't expect you to give an unexpected surprise!" Lei Tiantang said happily.

"Boss, to achieve such a big breakthrough is inseparable from the company's support. Without the various high-performance materials provided by the company, the strength of the aircraft fuselage we designed is not enough. We must know that supporting the aircraft's supersonic flight The body's structure and strength requirements are very high. If this problem can't be solved, our best design is useless!

The design of our engine is also because of the use of the company's high-performance materials, which makes the engine lighter and at the same time can withstand the pressure caused by the higher speed, which makes our engine more powerful than those used in fighters. It is more powerful, and only such a powerful power system can allow the aircraft to maintain such a high-speed cruise flight!"Sun Changhe explained with a smile.

To be honest, he and his colleagues in the laboratory are also very satisfied with their design. To know that this is a civil aircraft, and it is a luxurious private aircraft, they actually designed its performance to such a point that competitors are desperate. To the point, make them proud!

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.

The most famous of these is Aerion's AS2 supersonic private jet, which has received widespread attention since its release.

However, according to Aerion, the maximum speed of AS2 is only Mach 1.5, reaching a maximum range of 4,750 nautical miles at a cruise speed of Mach 0.95.In addition, the AS2 can cruise silently at a speed between Mach 1.1 and Mach 1.2.In areas where supersonic flight is not allowed, the aircraft is also capable of high-speed flight of Mach 0.99.

No matter from the flying speed or the flying distance, Sun Changhe's planes must completely explode them, the gap may be so exaggerated by 2 generations!

After all, at present, these supersonic private jets have no way to completely solve the various problems encountered in the design. For example, if the voyage is not enough, the supersonic flight will emit a huge noise, so that it will not be allowed to pass in densely populated areas. If these problems are not solved Even if it is put into the market, the desire of local tyrants to pay is not strong.

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

"This aspect cannot be solved absolutely, but we have optimized the design of the cause of noise in many ways. The aerodynamic shape of our aircraft is only finalized after being modified by millions of simulation tests. The purpose is to minimize the drag during supersonic flight.

And we also made special designs on the nose and wings to minimize the fluctuations caused by the impact.The biggest source of loud noise is the engine. In this respect, we have also optimized it during the design, and we have also specially designed the inside of the engine casing to reduce the huge noise generated by the high-speed rotation of the engine.

Although the noise standards of supersonic private jets are still arguing internationally, the noise of our current designed aircraft has been reduced to the standard of ordinary civil airliner flight. Even if they set strict standards, we can pass. of!"Sun Changhe explained with a smile.
