Chapter 435: new design

After completing all the tests in the sky, Yun 9 finally returned to the

combat readiness airport and was pushed into the hangar again after landing.

This time the test revealed many problems. The aircraft not only needs to be

inspected and maintained, but also repaired in many places.

When the leader came to the hangar with a group of people, he was about to ask

Chen Xin why he went to the sky with the plane, but saw that he was floating

in the air with the flying ability of nano armor to check the propeller of the

plane. If he was accountable, he had to hold back, and instead asked Chen Xin

about the plane.

"Academician Chen, how is the test flight going?" The leader raised his head

and asked Chen Xin, who was floating in front of the propeller.

Chen Xin heard the voice of the leader and turned his head to look at him.

Then he fell from the sky and greeted him: "Good leader, the flight test is

going well, but there are still many problems."

"Can you tell me more specifically?" When the leader heard Chen Xin say this,

his expression couldn't help but become serious.

"The flight situation of the aircraft in the troposphere is okay, but the

environment above the stratosphere is too harsh, and the aircraft is currently

unable to adapt to this situation." Chen Xin explained to the leader and

brought the leader to the aircraft's engine. The technician disassembled the

air filter and showed it to the leader: "Leader, please see here. Although

this air filter can effectively block sand and dust from entering the engine,

it also 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, and a large amount of sand and dust will affect

the air filter effect and lead to the aircraft. Engine power drops. ??"

Hearing what Chen Xin said, the leader's expression became a little dignified.

He asked Chen Xin: "Is there any way to solve this problem. Is the plane still

not able to fly normally?"

Facing the question of the leadership, Chen Xin replied: "At present, the

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 allow the aircraft to fly only below the stratosphere. If it does not

enter the stratosphere, the air environment in the troposphere is still

possible. Air filtration alone can ensure the normal flight of the aircraft.

Of course, we can also manufacture all-electric airplanes, thereby ignoring

the impact of dust and particles on airplane engines. This is also the second

modification plan I proposed. Micro nuclear reactors are used as the power

source for airplanes, thus using electric engines. To power the aircraft. ?

"Electric aircraft? Is this really possible?" a staff member beside the leader

asked Chen Xin.

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

"This is the electric aircraft I designed. It uses a 3 MW? nuclear reactor as

power to provide sufficient power for the aircraft's four engines." Chen Xin

said while pointing on the drawing: "I refer to the famous Osprey helicopter

for this aircraft. It also uses a tilt-rotor design, but compared to the

Osprey helicopter, this aircraft has four propellers, which can provide more

lift for the aircraft.?"

"Four propellers...How does this shape look a bit like a drone?" The leader

looked at the plane on the drawing, and felt that the layout of the propeller

was indeed like a drone.

Chen Xin nodded and did not shy away from what he was referring to. He replied

affirmatively: "I just referred to the drone's propeller layout design. It can

take off and land vertically like a drone, or it can be like an Osprey

helicopter. In the same way as a ski jump takeoff, when in the air, the four

propellers can provide both lift and thrust, which are sufficient for flying

in various complex environments.

And this design has an advantage over the original Osprey helicopter, that is,

two propellers on the front wing can be used to provide lift vertically, and

two propellers on the rear wing can be used horizontally to provide thrust.

There is no need to face many technical problems due to the changes of the

propellers like the Osprey helicopter, although I have solved these technical

problems. "

Hearing Chen Xin's words like this, the leader was deeply shocked.

In seven days, Chen Xin not only completed the transformation of the original

Yun-9 transport aircraft so that it could fly normally, but also completed the

design of this new helicopter, which was beyond his imagination.

Under normal circumstances, the design of an aircraft would take at least a

few years to complete. It took a full 20 years for the federally manufactured

Osprey helicopter to be 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 aircraft?" The leader settled, and

instead of showing his emotions on his face, he cared about the performance of

the aircraft instead.

"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,

and a payload of 20 tons. The maximum flight speed is 550km/h, and the

practical ceiling is 8000. Meters, because it is driven by nuclear power, its

flying distance has no upper limit." Chen Xin introduced the performance of

this aircraft in a very proud tone, and said quite proudly: "The performance

of this aircraft is slightly better than that of the Osprey. The helicopter

can carry 12 fully armed special forces soldiers or fly with 2 tons of

materials at a speed of 500km/h.

I want to announce that [\Mic\Mic\Reading\app\\] is really good, it is worth

installing, after all, you can cache books and read them offline!

Whether it is used for combat, disaster relief, or material transportation, it

can be perfectly competent. This is also the best solution I can think of

after referring to the current environmental conditions. After all,

conventional engines are always required for other aircraft. Faced with the

influence of sand and dust in the air. "

Having said that, Chen Xin also motioned to the leader to take a look at the

propeller of Yun-9.

The leader followed Chen Xin's instructions, and was surprised to find that

the propeller of the Yun 9 was full of scratches and abrasion marks, and these

marks were almost all over the windward side of the aircraft.

"It's okay if it's just the tropospheric flight, but if the aircraft rises

into a horizontal process, the large amount of particles and dust suspended in

the air will cause very large wear and tear on the aircraft under the

influence of the air flow. The faster the speed, the greater the wear.

Therefore, in the current situation, the stratosphere is still a no-fly zone.

Unless a higher-strength material is used to make the aircraft skin, it is not

afraid of wear and the engine can ignore the damage caused by dust. Otherwise,

I It is not recommended that any aircraft enter the stratosphere to fly. "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

damages on the surface of Yun9. After thinking about it, he nodded seriously.
