Desert base, evening.

A triangular aircraft was slowly pulled out of the hangar, and its whole body showed a very dirty gray, with irregularly sized patches appearing all over the fuselage, like a dusty antique that had been stored for more than ten years.

However, the fact is that it was only built half a month ago, and then the parts were transported here by transport plane to assemble, and today it is a high-speed run on the ground.

This is the first verification aircraft of the "Snow Bird", numbered H-10, that is, H-10.

After a year of design, Xuehu officially issued an order to the aviation manufacturing plants across the country to develop airframe parts, and in order to speed up the most important core airframe part handed over to the base, with the 120,000-ton pressure die forging machine manufacturing, the strength is fully up to standard.

For nearly seven months, the first theoretically flown demonstrator is now on the runway waiting for its first flight.

From the fuselage, skin, stealth technology, cooling technology, fuel, avionics and other aspects, the "Snow Bird" basically represents the ultimate level of the domestic aviation industry, of course, the most powerful has to be the three WCR-12 combined power engines that were successfully tested last year.

The grey aircraft has a simple and beautiful appearance, a far cry from the design style of mainstream aircraft, but full of a different kind of beauty.

Anderov, who became almost half of the chief engineer of the project, said to Dou Ping:

"This spacecraft can fly up to 52,000 meters, which has gone beyond the stratosphere into the mesosphere, and if it is named after the West, it should be called 'mesosphere lightning'.

Although the snowbird is also a beast of prey, her large face does not match her appearance. ”

Dou Ping: "It's Snow Hoove, Snow Bird is a polar hunter, relying on its pure white appearance can easily hide in the vast snowfield, and Snow Bird is a code name that has been used, which is easier to confuse." ”

Anderov: "Then I think the Polar Hunter is better than the Snow Bird." ”

“……”

The argument between the two over the code name didn't last long, as the ground run was about to begin.

Almost everyone in the research base stood on the side of the runway, looking forward to the run-and-run test.

In order to maintain maximum secrecy and avoid satellite reconnaissance, the run-and-run test was unusually conducted in the evening, when it was a little blurry when observed from a distance.

Test pilot Lei Qing sat in the cockpit wearing a special ultra-high-altitude pressurized flight suit, in fact, the flight suit he wore was close to the category of a spacesuit, and the price was extremely high.

He'd flown the simulator many times before, but the real cockpit was still exciting.

The Snowbird is equipped with the base's top-of-the-line avionics system, the style of the in-cabin console is very similar to that of the space shuttle, and it is equipped with powerful artificial intelligence and a 360-degree hologram projector.

When the holographic projection is turned off, it is like a small space shuttle, but when the holographic projection is turned on, the mask worth tens of millions will make the cockpit "disappear" through the algorithm and the cameras around the whole aircraft, except that the joystick in the hand is still retained, the pilot seems to have turned the "Snow Bird" out of the invisibility in the game plug-in, suspended in the air.

At this time, if you want to control the device, you can use holographic projections, gestures, and voice commands that are also floating in the air.

When he turned on the holographic mode in the hangar for the first time, Lei Qingdu, who had already overcome his fear of heights, was still a little startled, because it was too powerful, more powerful than the simulator, and there was almost no flaw in it, as if it was really suspended in the air.

The thought of experiencing the human body "levitating" in the air is a terrible attraction.

However, it is a pity that this event is not included in this run, and the ground high-speed taxi run test is the last procedure before the official first flight, except for the brakes and stop when the nose of the plane should be pulled, the rest are the same as normal takeoff.

Therefore, the ground crew must also be carefully checked in accordance with the official take-off procedures, and then fill 1/3 of the fuel for this aircraft, for high-altitude flight WCR12 is not used aviation kerosene, but an alkane mixed fuel containing metal cesium, which is difficult to volatilize and even a little viscous, and the fuel tank will be heated by the skin to enhance mobility during supersonic flight, and the APU can only be used after starting the APU preheating during ground takeoff.

With the ground staff and aircraft testing one by one, the tower issued a take-off command.

"1001, permission to take off!"

"1001 understands!"

Lei Qing pushed the throttle valve from 10% to the maximum value of the military push, that is, the maximum value of non-afterburner, and the three WCR-12s output a total of 20 tons of thrust at this time, because the prototype has less fuel and equipment, and the thrust-to-weight ratio is about 0.36.

This indicator is not low for a bomber, and it can reach 0.5 when afterburner.

The moment the wheel brake was released, the snow hoof gently lifted the nose and rushed forward, according to the design standards, the snow hoof with triangle + lift body design needs 2700 meters of gliding before it can be pulled up and taken off, 3100 meters safely, and the speed of 320 kilometers per hour is pulled, but because the empty weight is now relatively low, 2700 meters away from the brake is more appropriate.

Lei Qing felt the acceleration from the airframe, and his rich experience made him immediately judge that the thrust was slightly upward, which should be due to the light weight of the radar model and the design of the lifting body, which was within the normal range.

He just stared at the speedometer, watching the numbers on it increase rapidly, and when the speed exceeded 270 km/h, he was already preparing to press down on the nose of the plane to slow down, only to suddenly find that the altimeter jumped from 0 to 2.

Snowbird has no flaps and is pulled up by the rudder to deflection, but he is pretty sure he doesn't control it.

After he realized that it was the reason for the small empty weight of the airframe and the excellent lift-to-drag ratio of the lifting body, the altitude had exceeded 8m, and the snowbird had already detached itself from the ground by relying on the lift, and the sliding ran became its first flight.

Lei Qing immediately changed the original downward pressure action and instead pulled up the nose of the plane into an altitude of 800 meters and circled in a flat flight, and then reported the situation to the tower, and Anderov quickly understood what was happening.

"The design of the snowbird is better than we expected, and the speed is only 272 kilometers away when it is pulled up! The distance is less than 2200 meters, and the thrust of the engine is also very good. ”

Dou Ping: "That...... Let's test the first flight, hole, keep the landing gear out and circle around the field! ”

"Dong Yu received ...... She is very light to handle, not bulky at all, and has a speed of more than 550 km/h, and the landing gear is automatically retracted! ”

The acceleration of the "Snow Bird" is too fast, and the speed at which the landing gear can be deployed is limited, because it was an accidental flight plan that caused the flight computer to automatically retract the landing gear after the speed exceeded 500 kilometers per hour, so as not to cause a malfunction due to excessive windward pressure, and this happened during the little time of the call.

Lei Qing hurriedly reduced the throttle, Xuehu has supersonic cruise ability, and can fly at 1.3 times the speed of sound without afterburner, and if he accelerates again, he has to fly into supersonic speed, he is not ready for this.

Xuehu, who took the initiative to change subjects, flew around the base at high subsonic speed, then smoothly lowered the landing gear and began to land, and finally slid steadily for two kilometers before stopping.

Next time, it's supersonic flight.
