Chapter 702

Several airplanes took off smoothly again. This test flight is a type test flight, also known as an appraisal test flight. After the adjustment of flight test, it is necessary to comprehensively identify whether the new aircraft can meet the design technical specifications, check its flight performance, reliability and the feasibility of various measures taken during flight test adjustment, 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 the infinite gravity group with the powerful simulation and calculation ability of artificial intelligence and supercomputer. Millions of different types of simulated flights are not just for talking about. They have taken into account the details to be considered by sun Changhe. This is also the time they only used so short The reason for such a superior supersonic private jet!

After that, there are use test flights, which are flight tests carried out to prepare for the flight route or service under the actual use conditions. Its purpose is to further evaluate the operational performance and reliability of aircraft and its equipment, and to determine pilot training requirements, ground maintenance requirements and field support equipment.

In order to make the test representative, 10-20 aircraft are usually used for test flight. Sometimes adjustment, finalization and flight test are combined to shorten the flight test period. Of course, this step can not be saved. However, haidongqing can not produce such a large number of aircrafts to do test like ordinary civil aviation aircraft. After all, the positioning is different.

The stage of finalized flight test is the stage with the greatest risk, the longest time-consuming and the most subjects. At this stage, from the basic flight performance of the aircraft to the edge subjects, from avionics system to airborne weapons, comprehensive test should be carried out according to the flight test program.

Among them, avionics and airborne weapons flight test accounted for 60% to 70% of the total flight test. For many strength boundary subjects and special conditions, flight test risks are very high, such as stall, spiral, low altitude dive flight test, etc. of course, according to the actual performance of the fighter plane, we can also create high difficulty flight movements such as "Cobra", "bell" and "360 turn" of polar bear.

"Mr. Lei, why are four planes taking off at the same time? Are you going to test them at the same time?"

General Wu was very surprised by the operation of the tower and the movements after the plane took off. Even if he was well-informed, he and the Air Force leaders nearby were also very surprised.

Lei Tiantang replied with a smile: "yes! The purpose of this is to shorten the time of flight test, and at the same time, we can obtain the performance comparison data of the four aircrafts more accurately. All the aircraft are equipped with the most advanced experimental equipment. Our company's artificial intelligence system participates in the whole process of data collection, so that any small data difference can be detected!

General, are you worried about security? You can rest assured that we are also very precious for the precious pimples we have obtained from you. Since they are willing to operate in this way, they must also have confidence in the quality and technology of our aircraft. Judging from their training in this half month since they came to our company, our aircraft has absolutely conquered them! "

Such a confident answer surprised the Air Force leaders. It is not a good omen to know that overconfidence is pride.

"Mr. Lei, even if your company's technology is good, after all, this is the first time to engage in aircraft manufacturing. Is this kind of reckless operation really OK?" General Wu asked, frowning a little worried.

Seeing the expressions of general Wu and other Air Force leaders, Lei Tiantang could understand their worries. However, he still gave a gentle smile and did not give any explanation. He just replied with a firm smile: "without this diamond diamond, you can't do this porcelain work. Leaders will wait and see."

Since he is so confident, the Air Force leaders including general Wu are also looking forward to the performance of the aircraft.

"The radar wave active reflection device is turned on, and the aircraft stealth test begins!" This is when the first flight test begins.

Hearing such an order, these Air Force leaders are curious. What about the test content? This aircraft can reduce the radar reflection area and reduce the radar detection size to the size of an eagle. They still know that. What is the operation of actively increasing the transmitted waves?

General Wu asked curiously, "what does this test mean?"

"This function is set for normal navigation, because the aircraft designed by our company is a civil aircraft in the final analysis. In normal flight, there is no need to perform any stealth operation. Only when the aircraft is in crisis of missile or fighter radar tracking, can its stealth function be used.

What kind of stealth flight is a challenge to the air traffic control of various countries in ordinary times, so we specially designed this design to increase the radar reflection surface, and this device is turned on in normal flight Sun Changhe explained with a smile.

This explanation made the Air Force leaders understand the function of the test in an instant. Indeed, what do you do when you're on a commercial voyage? Do you want to do something? Neither they nor other countries will accept such a setting.

All kinds of tests were carried out slowly and orderly. The movements of climbing and diving at high elevation angle, turning at small angle and rolling 360 degrees were skillfully flown out by these elite test pilots.Even in a low altitude flight, the four aircraft also carried out a leaf floating maneuver, which made the leaders of the air force gape!

"That's too much exaggeration! Can you fight with a fighter?! When I look at a lot of civil aircraft, it's just that they don't perform as well as I do? Is it necessary to exaggerate? " An air force leader exclaimed in an incredible tone.

"This just proves how excellent the performance of this aircraft designed by our company is! We want to know that we are positioning this aircraft as a super luxury private aircraft, not to mention that this aircraft is our boss's future special plane. Who is not the super rich who can afford this supersonic private plane in the future? Of course, their pursuit of aircraft performance will be different from others!

Leader, you have also said that the performance of our plane matches the maneuverability of some fighters, which will be one of the core selling points of this aircraft. Because such performance and other safety measures on the plane will bring the richest people the greatest sense of security when they travel. The attraction of this point can bring us a large number of orders ！” Sun Changhe explained with a smile.
