Vol 2 Chapter 706: A private jet that can fly faster than the 5th generation fighter jet!

　　 "Okay, Director Sun! Don't sell it, please tell me about its performance!" Lei Tiantang urged with a smile.
"Good boss! This supersonic private jet numbered c1 in our laboratory has a fuselage of 59 meters, a height of 7.6 meters, and a wingspan of 23 meters. The aircraft is designed to carry 18 passengers. I think this is the number of passengers. It is enough whether it is used by the boss or high-level company in the future.
　　 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 in it!
　　 The entire fuselage uses a large number of the company's high-strength lightweight alloy materials, making this aircraft not only lighter, but also the aircraft's fuselage strength is particularly strong, which is also the greatest guarantee that it can fly at supersonic speeds!
Using two sw1 super engines designed by our laboratory, it can make its cruising speed reach Mach 2.2, and its maximum flight speed can reach Mach 2.8. Even if it is flying at cruising speed, it will fly from Hefei to 2695 kilometers per hour. It only takes a little over 4 hours in Boston!
And because our engine also uses our company’s high-performance materials and a brand-new intelligent fuel consumption control system to make its fuel consumption lower than that of an ordinary aircraft, it can reach a range of 13,000 when the fuel is filled once. Kilometers, enough boss you to fly from Hefei to any place in the world! "
　　 "What?! Why is the speed so fast!" Lei Tiantang was really surprised by the speed of the plane!
　　According to the latest information, the old American f22 has a flying speed of 2410 kilometers per hour, which is quite remarkable, and it is absolutely worthy of the f22's outstanding life experience. As the main battle equipment of the old and American high-tech, this aircraft has been in service in 2005. The "4s" standard established by it is still the recognized standard and direction of the world fighter aircraft.
The Polar Bear’s Su-57 fighter has a flying speed of about 2,140 kilometers per hour. It 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 from the Polar Bear. Although it is economically troubled, the equipment is obsolete and the electronic system is backward Waiting for difficulties, but after unremitting efforts, it is finally ready to serve. Although the aircraft has poor stealth performance, its mobility is excellent.
　　 And our J-20 has a flying speed of 3430 kilometers per hour. The most distinctive duck aerodynamic layout of the J-20 makes it the most prominent in its super-maneuverability. Even if it was the J-20c that was just announced not long ago, his flight speed has not increased too much, and the flight speed has only reached 3,900 kilometers per hour!ァ新ヤ~⑧~1~中文网ωωω.χ~⒏~1zщ.còм
From the flying speeds of the most advanced 5th-generation aircraft in the world above, we can compare how advanced the flying speed of the supersonic private jet designed by Sun Changhe and others is. It can actually reach the speed of a fighter jet. Up!
　　 You know this is a civilian airplane! It is two concepts with fighter jets, and it is incomparable even in terms of size. The size of this private jet in front of us is at least two times larger than those of fighter jets. Everyone knows that larger aircraft want to fly. The faster the speed, then its engine performance must make a very big breakthrough!
　　 "My biggest expectation for you was to make it cruise at Mach 1.5. I didn't expect you to give an unexpected surprise!" Lei Tiantang said happily.
"Boss, to achieve such a big breakthrough, it is inseparable from the support of the company. Without the various high-performance materials provided by the company, the strength of the aircraft fuselage we design is not enough. The structure and strength requirements of the body are very high. If this problem cannot be solved, our design will be useless!
The design of our engine is also because of the use of the company’s high-performance materials, which makes the engine lighter, while also being able to withstand the pressure brought by greater speed, which makes our engine more powerful than those used in fighter jets. 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. You must know that this is a civil aircraft, and it is a luxurious private aircraft. They actually designed its performance to such a desperate competition. To the point, make them proud!
　　 With the development of supersonic flight, many aircraft manufacturing companies in the world have begun to put a lot of energy into supersonic private jets.
　　 The most famous of these is the company's as2 supersonic private jet, which has received widespread attention since its release.
　　 But according to the company, the as2 has a maximum speed of Mach 1.5, reaching a maximum range of 4,750 nautical miles at a cruising speed of Mach 0.95. 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, this aircraft can still fly at a high speed of Mach 0.99~EbookFREE.me~ Whether it is in terms of speed or distance, the aircraft designed by Sun Changhe must completely explode. There may be such an exaggerated generation difference between the 2 generations!
After all, these supersonic private jets currently have no way to completely solve the various problems encountered in the design. For example, the range is not enough. When flying at supersonic speeds, they will emit huge noises and are not allowed to pass in densely populated areas. If these problems are not resolved , Even if it is invested in the market, the desire of the local tyrants to pay is not strong.
　　 "Yes! But we all know that the noise of airplanes is very loud when flying at supersonic speed. Have you solved this problem?" Lei Tiantang is also very concerned about this problem.
"This aspect is impossible to absolutely solve, but we have optimized the design of the causes of noise from many aspects. The aerodynamic shape of our aircraft has been modified after a million times of simulation tests. Yes, in order to minimize the drag when flying at supersonic speeds.
　　 And we also made special designs on the nose and wings to minimize the fluctuations caused by the impact. The biggest source of loud sound is the engine. In this regard, we have also optimized it when designing, and a special design has been made inside the engine shell, which can reduce the huge noise generated by the engine's high-speed rotation.
Although the international community is still arguing about the noise standard of supersonic private jets, the noise of our current design has been reduced to the standard of ordinary civil aviation airliners. Even if the standards set by them are strict, we can pass the barrier. of! "Sun Changhe explained with a smile.
