Several airplanes took off smoothly again. This time the flight test was a finalized flight test, which is also called an appraisal flight. After adjusting the flight test, comprehensively appraise whether the new aircraft meets the design technical indicators, assess its flight performance, reliability and the feasibility of various measures taken during the adjustment test flight, and decide whether it can be put into mass production.

　　

Of course, there should have been research flight test and adjustment flight test before this, but these two steps were solved by Infinite Gravity Group using artificial intelligence plus the powerful simulation computing capabilities of supercomputers. Millions of different types of simulated flights are not. Just to talk about it, Sun Changhe has considered the details that should be considered. This is why they completed such a supersonic private jet with superior performance in such a short time!

　　

　　 There is also a test flight after this, which is a test flight in preparation for the flight or service under actual conditions of use. Its purpose is to further evaluate the performance and reliability of the aircraft and its equipment, and to determine pilot training requirements, ground maintenance requirements and field support equipment.

　　

　　In order to make the test representative, usually 10-20 aircraft are used for test flight. Sometimes the adjustment, finalization and flight test are combined to shorten the flight test cycle. Of course, this step cannot be saved. However, it is impossible for the Costin to produce such a large number of aircraft for testing like ordinary civil aviation aircraft. Positioning is different.

　　

　　The stage of finalized flight test is the most risky, time-consuming, and most subject test flight phase. At this stage, from the basic flight performance of the aircraft to the marginal subjects, from the avionics system to the airborne weapons, all tests must be conducted according to the flight test outline.

　　

　　Among them, avionics and airborne weapon test flights accounted for 60% to 70% of the total test flights. Many strength boundary subjects and special state flight tests are very risky, such as stalls, spirals, low-altitude dive test flights, etc. Of course, according to the actual performance of the fighter, it is also possible to create original polar bears such as "Cobra", "Clock", and "360 Turn". Difficult flying maneuvers.

　　

　　 "Mr. Lei, how come 4 planes take off at the same time? Are you planning to test them at the same time?"

　　

　　 General Wu felt very strange about the operation of the tower and the actions of running down to the plane after taking off. The operation of the test flight was very surprised even if he and the air force leaders next to him were very knowledgeable.

　　

Lei Tiantang smiled and replied: "Yes! The purpose of this is to shorten the flight test time, and at the same time, to obtain more accurate performance comparison data of these four aircraft. The aircraft are equipped with the most advanced experimental equipment. The company's artificial intelligence system participates in data collection throughout the entire process, so that even the smallest data differences can be detected!

　　

　　General, are you worried about safety? You can rest assured that we are very precious to the baby bumps we asked for from you. Since they are willing to do this, they must also have confidence in the quality and technology of our aircraft. From the time they came to our company. Judging from the training in the past months, our aircraft absolutely conquered them! "

　　

　　 Such a confident answer surprised the leaders of the Air Force. You must know that excessive self-confidence is pride. This is not a good sign.

　　

　　 "Mr. Lei, no matter how good your company's technology is, after all, this is the first time you are engaged in aircraft manufacturing. Is this kind of reckless operation really okay?" General Wu asked with a worried brow.

　　

Seeing the expressions of General Wu and other Air Force leaders, Lei Tiantang could understand their concerns, but he still smiled gently, without explaining much, but replied firmly with a smile: "Without this diamond, I won't take this porcelain. Live, all leaders will wait and see!"

　　

　　 Seeing this, everyone is not saying anything. Since he is so confident, Air Force leaders including General Wu are also looking forward to the flight performance of this aircraft.

　　

　　 "The radar wave active reflection device is turned on and the aircraft stealth test is started!" At this time, the work of the first flight test began.

　　

　　 These Air Force leaders are curious when they hear this order, and what is the test content? They still know that this aircraft can reduce the radar reflection area and reduce the detection size of the radar to the size of an eagle. What is the operation of actively increasing the transmitted wave?

　　

　　 General Wu asked curiously: "What does this test mean?"

　　

"This function needs to be set for normal navigation, because the aircraft designed by our company is still a civil aircraft in the final analysis. During normal flight, there is no need to perform stealth operations at all, only when the aircraft is exposed to missiles. Or when it is in crisis, such as fighter radar tracking and shrinking, its stealth function can only be used.

　　

　　 Whatever stealth flight when sailing is a challenge to the air traffic control of various countries, so we specially designed this design to increase the radar reflection surface, and this device is always turned on during normal flight. "Sun Changhe explained with a smile.

　　

　　This explanation made Air Force leaders understand the function of this test instantly. Indeed, what do you do in hiding during normal business voyages? Do you want to do things? Neither they nor other countries will accept such a setting.

　　

The following tests were carried out slowly and orderly. The movements of climbing and diving at large elevation angles, turning at small angles, and 360-degree rolls were all skillfully carried out by these elite test pilots~lightnovelpub.net~ even in During a low-altitude flight, all four aircraft also carried out a leaf-floating maneuver, which made the air force leaders stunned!

　　

"This is too exaggerated! You can fight with fighter jets, right?! It's just a civilian aircraft, or a civilian aircraft of this size. How can I see that it is no worse than many fighters when doing these actions? What? Is it necessary to make such an exaggeration?" An Air Force leader exclaimed in an incredible tone.

　　

"This just proves how excellent the performance of this aircraft designed by our company is! You must know that we have positioned this aircraft as an ultra-luxury private jet, not to mention that this aircraft is our boss’s future special plane, but the future Whoever bought this supersonic private jet is not a super rich person. Of course, their pursuit of aircraft performance must be different!

　　

Leader, you also said that the performance of our aircraft is comparable to the maneuverability of some fighters. This will also be one of the core selling points of our aircraft, because this performance plus the aircraft’s Other safety measures will give the richest people the greatest sense of security when they travel, and this attraction can bring us large orders! "Sun Changhe explained with a smile.
