Doomsday Bunker Upgrade Chapter 433: New design

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

This time the test revealed many problems, and the aircraft not only had to be inspected and maintained, but also had to be 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 plane The propeller, the accountability 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, 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?" When the leader heard Chen Xin say this, his expression became serious.

"The flight situation of the plane in the troposphere is OK, but the environment above the stratosphere is too harsh, and the plane can't adapt to such a situation at present." Chen Xin explained to the leader, and took the leader to the engine of the plane, The air filter that has been dismantled by the ground crew is shown 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 blocks the entry of sand and dust.

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 accumulation will affect the air filter effect. , resulting in a drop in aircraft engine power. ??”

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, is the plane still unable to fly normally??"

Faced with the leader'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 plane fly only below the stratosphere. If it doesn't enter the stratosphere, the air environment in the troposphere is still fine. Air filtering alone can ensure the normal flight of the plane.

Of course, we can also build an all-electric aircraft, thus ignoring the impact of dust and particles on the aircraft engine. This is also the second modification I propose, using a miniature nuclear reactor as the power source for the aircraft, thereby Electric engines are used 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 writing on the drawings. Pointing: "I refer to the famous Osprey helicopter for this aircraft, 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... How does this shape look 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 answered 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 take off and land vertically. Ski-jump takeoff like an Osprey helicopter, and 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.

I don't have to face a lot of technical issues like the Osprey due to the change of the propellers, even though I have already solved them. "

The leaders were deeply shocked when they heard Chen Xin say such words.

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 several years to complete. It took a full 20 years for the Federal Osprey helicopter to be put into service!

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

"How is the performance of this aircraft?" The leader was calm, and instead of expressing his emotions on his face, he focused on the performance of the aircraft.

"The aircraft is 20 meters long, with 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 load capacity of 20 tons ~IndoMTL.com~ The maximum flight speed is 550km/h, and the practical ceiling is 8000 Mi, because it is powered by nuclear power, its flight distance has no upper limit." 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. The helicopter can carry 12 fully-armed special forces soldiers, or carry 2 tons of supplies at a speed of 500km/h.

Advertisement, [mimireadingapp\] is really good, it is worth installing it, after all, you can read books in cache and read aloud offline!

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, other aircraft have conventional engines. Always face the effects of sand and dust in the air. "

Chen Xin said this, and 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 Y-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, a 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.

So under the current circumstances, the stratosphere is still a no-fly zone. Unless a higher strength material is used to make the aircraft skin, it can not be afraid of wear and tear, and the engine can also ignore the damage caused by dust. If so, I would not recommend any aircraft to fly into the stratosphere. "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 Yun 9. After thinking about it, he nodded seriously.
