After a while, the inspection and preparation of the M29 competitive jet had been done, Xiao Weiguo quickly climbed into the cockpit under the concerned gaze of everyone, he made a successful gesture to everyone, and then closed the cockpit canopy, ready to enter the first taxi test, and even take off directly from the runway if the conditions are met.

There are two types of running tests: low-speed running and high-speed running tests. In fact, when the new aircraft is taxiing on the ground, the aircraft is being tested, because it is moving on the ground by its own power before takeoff, it is necessary to test the aircraft under the minimum thrust, that is, in the state of slow driving, in the state of high thrust and close to the ground speed when the high-speed taxi test process will also lift the front wheel of the aircraft, simulating the take-off state of the aircraft.

An important purpose of the taxiing test of the new aircraft before the first flight is to check whether there is a problem with the structure of the aircraft under the taxiing vibration conditions, whether the various systems are working normally, whether the brakes of the aircraft meet the requirements of take-off and landing, which also includes the maximum engine thrust, whether the brakes are effective, and whether the brakes are effective in emergency situations, how well the aircraft is controlled in the taxiing process, whether it can keep taxiing in a straight line, and whether it can be corrected if there is a deviation. When taxiing at high speeds, it is also necessary to check whether the attitude control of the aircraft after lifting the front wheels is normal. Only when these conditions are met, can it take off, of course, sometimes there will be accidents, which requires test pilots to be flexible and flexible.

Especially for high-speed taxiing, if a problem is found in the process of lifting the front wheel, then whether it should be braked urgently or directly up, which requires the test pilot to have a correct judgment. For example, there has been such a situation in the history of aviation, in 1994, when the YF-16 aircraft of the United States was in a high-speed taxiing test, it was due to the oscillation caused by lateral piloting, and the test pilot was in a hurry. Pushing the throttle with a lever, the plane flew off the ground and unexpectedly achieved its first flight. In order to ensure that the runway is not rushed out of the runway during ground taxiing, it is first necessary to set up markers on the runway so that the test pilot can visually align with the runway position. Of course, there is no such equipment now, so it can only be simplified.

The main runway of Dragon Soul Aircraft Manufacturing Co., Ltd. is 2,500 meters long. It was also built for the M40 large transport aircraft. Now there is no problem with everything, just waiting for Xiao Weiguo to start the wind and thunder jet engine, which is also the first test, whether the engine system of the aircraft can start normally, which is related to whether it can enter the taxi test, whether it can carry out the test flight according to the flight test plan.

Messerschmidt, Lucas, Cam, Horton Brothers, and more than 100 Dragon Soul Aircraft Manufacturing employees closely watched the M29 competitive jet movements, and they were even prepared to fail, and if there was a problem with the engine, or even a fire, they set up a plan to deal with it. It's just that they don't want that to happen!

After Xiao Weiguo started the power supply of the aircraft. After carefully checking the cockpit instruments, although they are still using the old-fashioned dial-style instruments, the cockpit design still fully considers the human-machine interface, and the position of the instruments and switches is very easy to view and operate. And the cockpit of the plane is still relatively spacious, with Xiao Weiguo's height of nearly 1.9 meters, he still won't feel crowded when he sits inside.

There was nothing wrong with everything, Xiao Weiguo started the wind and thunder jet engine, and he just felt the whole fuselage shake a few times while sitting in the cockpit of the plane. Then the engine tachometer pointer began to point to a position of more than a thousand revolutions, and the jet engine was successfully started!

Messerschmidt and the others only saw a flash of fire from the tail vent of the plane. Then I saw the plane shake a few times, and then a hot flame erupted from the tail of the plane, roasting the ground and deformed, in fact, at this time the engine of the plane was just a slow train, the thrust was not large, and there was a brake lock. The plane did not move.

Xiao Weiguo checked the instruments in the cockpit of the plane again, and then manipulated the rudder surfaces of the plane to see if the control was flexible, which is a check that must be done before the plane takes off, although it is now about to carry out the taxiing test of the aircraft. However, just in case, that is, in the case of accidental take-off, it is very necessary to test operate these control surfaces that are very important during the flight.

The design and manufacture of the control system of the M29 competitive aircraft are very good, there is no problem at all, Xiao Weiguo then increased the throttle valve of the engine, and tested whether the engine inlet meets the requirements after its thrust increases, and at this time it is still relying on the brakes of the aircraft to set the aircraft on the ground. However, Xiao Weiguo didn't dare to drive too big, for fear that the brakes would not be able to withstand it, after all, the thrust of the wind and thunder jet engine was still very large.

Everything looked perfect, Xiao Weiguo released the brakes of the plane, and the M29 competitive jet without brake constraints began to slowly glide forward, and soon accelerated under Xiao Weiguo's operation! Everyone present was extremely excited, and who could be calm to witness the first flight of the first jet plane in human history? This is a great day in the history of human aviation, and it is also the pride of the Dragon Soul Ordnance Complex! The emergence of jet aircraft will break the limitations of aircraft in terms of speed and altitude, and its application prospects will be incomparably broad!

Everyone watched as the M29 competitive jet continued to accelerate, taxiing faster and faster, and the roar of the engine became louder and louder, it was like a huge eagle, and the large swept wings were like the strong wings of the eagle, constantly shaking up and down in the taxiing, like the eagle was about to spread its wings and take off.

All the people were thrilled and excited! In particular, the employees who participated in the design and manufacture of the M29 competitive aircraft witnessed it turn from a drawing into a real thing, and came to the runway for testing, and their hard work was not in vain!

Xiao Weiguo piloted the M29 competitive jet, and after increasing the throttle, the plane's taxiing speed soon increased to 250 kilometers per hour, which is already quite fast, almost close to the speed above the ground. Xiao Weiguo hurriedly manipulated the flat tail to deflect to lift the front wheels of the plane, because the taxiing distance had passed half, and the length of the runway in front was not much.

However, he tried twice and didn't lift the front wheel, which made him a little anxious, and now he is running fast, should he brake hard and release the throttle to stop, or continue to try again? If you can't stop in time, the plane may slide out of the runway and into the grass, which will definitely have to take the big top.

Xiao Weiguo decided to try again, as the flat tail deflected to the maximum angle, the front wheel finally lifted, at this time Xiao Weiguo found that the runway in front of him did not seem to be long, and it was already difficult to stop at this time! Xiao Weiguo decided to take off, and at this time, the only way to take off decisively is the best choice!

Messerschmidt and they also saw that the abnormality was coming, because Xiao Weiguo had not lifted the front wheel of the plane yet, they all stretched their necks to look at the rapidly taxiing plane, fortunately Xiao Weiguo finally let the front wheel of the plane lift, but before they could react, they saw that the M29 competitive aircraft was faster, and after two or three seconds, its rear wheels also left the ground, and the plane took off and successfully flew into the sky! It was an unexpected first flight! (To be continued.) )
