Doomsday Bunker Upgrade

After all the tests were done in the sky, Yun 9 finally returned to the combat readiness airport, and was pushed back into the hangar after landing.

This time the test revealed many problems, the aircraft not only had to be inspected and maintained, but even repaired in many places.

When the leader brought a group of people to the hangar, he was about to ask Chen Xin why he wanted to go to the sky with the plane, but he saw that he was hovering in the air with the flight ability of the nano armor to check the propeller of the plane. If he was to be held accountable, he had to hold back, and turned to Chen Xin to ask about the situation of the plane.

"Academician Chen, how's the test flight going?" The leader raised his head and asked Chen Xin who was hovering in front of the propeller.

Chen Xin heard the leader's voice, turned his head and glanced at him, and then fell from the sky and greeted him: "Good leader, this flight test went well, but there are still many problems."

"Can you be more specific?" The leader couldn't help but become serious when he heard Chen Xin say this.

"The flight situation of the plane in the troposphere is OK, but the environment above the stratosphere is too harsh, and the plane cannot adapt to such a situation at present." Chen Xin explained to the leader, and brought the leader to the engine of the plane, which will have been taken by the ground crew. The air filter removed by the technician showed it to the leader: "Leader, please look here, although this air filter can effectively prevent sand and dust from entering the engine, it also has serious dust accumulation because it prevents sand and dust from entering the air filter itself.

Because there are a lot of dust and particles in the stratosphere, the engine will inhale a lot of air during the flight, which will cause sand and dust to accumulate in the air filter. Power drops. "

Hearing Chen Xin say this, the leader's face became a little dignified. He asked Chen Xin, "Is there any way to solve such a problem, can't the plane fly normally now?"

In the face of the leadership's question, Chen Xin replied: "The current environment is like this, we have no way to solve it, but if we want to make the plane fly normally, there is still a way.

We can let the aircraft fly only below the stratosphere. If it does not enter the stratosphere, the air environment in the troposphere is still acceptable. Air filtering alone can ensure the normal flight of the aircraft.

Of course, we can also make all-electric aircraft, so as to ignore the impact of dust and particles on the aircraft engine, this is also the second modification I proposed, using a miniature nuclear reactor as the power source of the aircraft, so as to use an electric engine to power the aircraft.

"Electric aircraft? Is this really possible?" A staff member next to the leader asked Chen Xin.

Chen Xin nodded and took out a drawing to show the leader.

"This is exactly the electric plane I designed. It uses a 3 megawatt nuclear reactor as power to provide sufficient power for the four engines of the plane." Chen Xin said while pointing at the drawing: "This is For the aircraft, I refer to the famous Osprey helicopter, which also adopts a tilt-rotor design, but compared to the Osprey helicopter, this aircraft has four propellers, which can provide greater lift for the aircraft.”

"Four propellers... Why is this shape a bit like a drone?" The leader looked at the plane on the drawing and felt that the layout of the propellers really looked like a drone.

Chen Xin nodded, and did not shy away from what he was referring to, and replied affirmatively: "I just refer to the propeller layout design of the drone, it can take off and land vertically like a drone, or it can be like an Osprey helicopter. Just like ski-jump takeoff, the four propellers can provide both lift and thrust when in the air, which is sufficient for flying in various complex environments.

And this design has an advantage over the original Osprey helicopter, that is, it can use two propellers on the front wing to provide lift vertically, and two propellers on the rear wing to provide thrust horizontally.

I don't have to face many technical problems due to the change of the propeller like the Osprey helicopter, although I have solved all these technical problems. "

Hearing Chen Xin say such words, the leaders were deeply shocked.

In seven days, Chen Xin not only completed the transformation of the original Y-9 transport aircraft so that it could fly normally, but also completed the design of this new type of helicopter, which was beyond his imagination.

Under normal circumstances, the design of an aircraft takes at least a few years to complete. It took the federal Osprey helicopter 20 years to put into use!

At this moment, the leader finally had an intuitive understanding of Chen Xin's ability.

"Then how is the performance of this plane?" The leader calmed down, and instead of expressing his emotions on his face, he was concerned about the performance of the plane.

"The aircraft is 20 meters long, has a maximum wingspan of 16 meters, a height of 7 meters, an empty weight of 16 tons, a maximum take-off weight of 40 tons, a load capacity of 20 tons, a maximum flight speed of 550km/h, and a practical ceiling of 8,000 meters, because it is powered by nuclear power , there is no upper limit for its flight distance." Chen Xin introduced the performance of this aircraft in a proud tone, and said quite arrogantly: "The performance of this aircraft is slightly better than that of the Osprey helicopter, and it can carry 12 full-fledged crew members. Armed special forces soldiers, or flying with 2 tons of supplies at a speed of 500km/h.

Whether it is used for combat, disaster relief, or material transportation, it can be perfectly competent. This is the best solution I can think of after referring to the current environmental conditions. After all, conventional engines for other aircraft always require Faced with the effects of sand and dust in the air. "

When Chen Xin said this, he also motioned for the leader to take a look at the propeller of the Yun-9.

The leader followed Chen Xin's instructions and was surprised to find that the Yun 9's propeller was full of scratches and wear marks, and such marks were almost all over the windward side of the entire aircraft.

"It's fine if it's just flying in the troposphere, but if the plane rises into a flat flow, the large amount of particles and dust suspended in the air will cause a lot of wear and tear to the plane under the influence of the airflow, and the faster the speed, the greater the wear and tear.

Therefore, under the current circumstances, the stratosphere is still a no-fly zone, unless a higher strength material is used to make the aircraft skin, which is not afraid of wear and tear, and the engine can also ignore the damage caused by dust, otherwise, I will It is not recommended for any aircraft to enter the stratosphere for flight. "Chen Xin looked at the leader and said to him very solemnly.

After listening to Chen Xin's words, the leader looked at the scratches and damage on the surface of the Yun9. After thinking about it, he nodded seriously.

There is a four-engine design in the design draft of the Osprey, and this design is applied here, and the performance is slightly enlarged.
