When the cockpit canopy of the M29 aircraft was opened, Xiao Weiguo climbed out of the cockpit and was surrounded by excited employees! Especially the Horton brothers, the two of them now worship Xiao Weiguo to the extreme! Because Xiao Weiguo not only has profound attainments in various fields of the weapons industry, but also is proficient in military theory, can fly to the sky, and has the fearless spirit of a test pilot, all of which makes the two of them feel incomparably small in front of Xiao Weiguo, which strengthens the belief that the two of them want to work in the Dragon Soul Ordnance Industry Complex! By participating in the work of the M40 transport aircraft project, they deeply understood that it was not as simple as imagined to design and manufacture an advanced aircraft, and it was far from enough to rely on enthusiasm, and it was impossible to build a good aircraft without the support of systematic aeronautical engineering theory and aviation industry foundation.

Lei Ma stood in front of Xiao Weiguo and said excitedly: "Mr. Philip, we have succeeded!" You're so great, how could this taxi suddenly turn into a test flight? ”

Xiao Weiguo couldn't suppress the blood in his heart, and laughed loudly: "Hahaha! What a bonus! In fact, I was too nervous at that time, I thought that I and the M29 plane were going to be finished, because the plane taxied very fast, and the distance of the runway was no longer enough for the plane to stop, so I decisively chose to take off, which will have today's unexpected first flight. But our first flight was unexpectedly smooth, and I also flew amazing data, don't be too excited to hear this data! ”

Messerschmidt hurriedly said: "Philip, tell me quickly, how fast the speed of the M29 has reached!" I guess jets should be at least 600 kilometers per hour. And how did you fly in the air for so long, so we are so worried! ”

Xiao Weiguo laughed and said, "It scares you when you say it!" In this test flight, the M29 aircraft performed well, and the strong thrust of the wind and thunder engine was not ordinary! This allows me to push it to the limit with confidence. On this flight. The M29 aircraft climbed to an altitude of 15,000 meters, and at this altitude reached a maximum level flight speed of 1,000 km/h, and a cruising speed of 850 km/h! Moreover, its climb rate is also amazing, reaching an average of more than 40 meters per second! ”

As soon as Xiao Weiguo broke out the limit data of the test flight, the whole crowd was boiling! Such data. They couldn't believe it! Even Cam, the chief designer of Dragon Soul Aircraft Manufacturing Co., Ltd., almost suspected that he had misheard, and he hurriedly said, "Mr. Philip, is the data you just said true?" How is this possible? I can't be mistaken! ”

Xiao Weiguo smiled: "Everyone heard it right! This is real data! And I believe that with continued test flights and adjustments, these records will be broken! Even I wanted to hit the speed of sound, but unfortunately the plane tremored at a speed close to 1,000 km/h, so I had to stop taking risks, after all, it was the first test flight. And safety first! ”

Cam nodded and said, "yes, it's dangerous to get into flutter. Because flutter is the most important topic in aeroelastic mechanics. When the aircraft is flying at low speeds, any free vibration of the wings will be attenuated by damping. However, when the flight speed exceeds a certain value, a small disturbance will cause vibration divergence, and the amplitude will increase sharply, so that the wing will be destroyed within 2~3 seconds, and there is a phase difference between the instantaneous aerodynamic force and elastic displacement of the wing surface vibration, so that the energy required for vibration divergence will be injected into the structural vibration from the airflow. Flutter occurs when the work done by the aerodynamic force is greater than the work consumed by the damping force. Flutter is a dynamic stability issue. It seems that we also have to make detailed theoretical calculations and adjustments to the M29 aircraft. ”

Xiao Weiguo agreed: "Yes, the M29 aircraft needs to be further optimized in the test flight, and we need to make some minor adjustments to make it a perfect competitive aircraft." And it has the potential to be a formidable jet fighter in the future. We can even make it a supersonic fighter. However, the aerodynamic shape needs to be corrected. Now that we have a jet, a turboprop engine test flight is almost underway, and the M40 large transport aircraft is about to roll off the assembly line, which is a good thing! ”

Messerschmidt said: "To be a fighter, the M29 needs to be improved a lot!" However, it was designed with room for upgrading. Come to think of it, that's not a problem! ”

Xiao Weiguo smiled: "Yes, I have already considered this!" Therefore, the M29's airframe space is still very sufficient, and it can completely increase the weight by two to three tons, which are fuel and weapon systems. Of course, when it comes to airborne weapons, our aviation Vulcan artillery has to be developed more intensively! It had to be synchronized with the M29! In addition, I am also preparing to develop an airborne radar for future jet fighters, and the nose space of our M29 aircraft is used for radar. That's why I designed the air intakes on both sides of the fuselage! ”

Walter said suspiciously: "Mr. Philip, what kind of equipment is the airborne radar?" It's pretty fresh. ”

Xiao Weiguo said: "Everyone must know that radar is a kind of equipment used for detection and ranging. But we now have to put the radar on the plane, which means that we can use the radar on the plane to detect targets in the air and on the ground, and determine their position in space, which is very important for fighters. If you have an airborne radar, you can detect the enemy before you can fire it, and the chances of winning in an air battle will be greatly increased! Moreover, with the development of radar technology, the task of radar will not only measure the distance, bearing and angle of the target, but also measure the speed of the target, as well as obtain more information about the target from the target echo. In the future, it will even be possible to use radar to guide airborne weapons in combat! ”

Cam was also surprised: "Ah, Mr. Philip, you still see farther!" We never imagined that the bulky radar would be able to be carried on the plane, and it would be in the nose of the M29, which is not too big. I'm afraid it's not a small difficulty, right? ”

For the role of airborne radar, how can Xiao Weiguo not know! That's the essential weapon of the fighter of the future, the eyes of the fighter! Airborne radars were introduced during World War II, so they weren't too difficult. British scientist Edward? A research team led by Bowen began developing airborne radars in 1935. In mid-1937, a small radar was developed and mounted on a twin-engine Ansan, which became the first aircraft to carry radar. The airborne radar has undergone several tests and proved that it can detect surface ships at a distance of 16 km. Shortly after the outbreak of World War II in 1939, Dr. Bowen presided over the development of the ASVMK1 airborne sea-to-sea search radar and the A1 airborne night-borne radar to officially equip the United Kingdom, becoming the world's first practical airborne radar. Later several improvements were made to both radars, which played an important role in the fight against German submarines and night bombers. (To be continued.) )
