Chapter 434

After all the tests in the sky, yun-9 finally returned to the combat readiness airport and was pushed into the hangar again after landing.

Many problems have been exposed in this test. The plane not only needs to be inspected and maintained, but also needs to be 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 wanted to go up with the plane. However, he saw that he was floating in the air with the help of the flight ability of nano armor to check the propeller of the plane. He had to hold back the responsibility and asked Chen Xin about the plane.

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

Hearing the leader's voice, Chen Xin turned his head and looked at him. Then he came down from the sky and said hello to him: "good leader, the flight test is good, but there are still many problems."

"Can you be specific?" When the leaders heard Chen Xin say this, they couldn't help being serious.

"The flight condition of the aircraft in the troposphere is OK, but the environment above the stratosphere is too bad for the aircraft to adapt to this situation at present." Chen Xin explained to the leader, and took the leader to the bottom of the engine of the aircraft, and showed the air filter that had been removed by the ground service technician to the leader: "leader, please look here. Although this air filter can effectively prevent the dust from entering the engine, it also has serious dust accumulation because it blocks the dust from entering the engine.

Because there are a lot of dust and particles in the stratosphere, the aircraft engine will inhale a lot of air during flight, which will cause dust accumulation in the air filter, and a lot of dust accumulation will affect the air filter effect, resulting in the decrease of aircraft engine power.  "

hearing Chen Xin say so, the leader's face became a little dignified. He asked Chen Xin," is there any way to solve this problem? Can't the plane fly normally now?  "

facing the leader's question, Chen Xin replied:" at present, the environment is like this, we have no way to solve it, but if we want to make the aircraft fly normally, there are still ways.

We can make the aircraft only fly below the stratosphere. If it doesn't enter the stratosphere, the air environment in the troposphere is OK. The normal flight of the aircraft can be guaranteed only by air filtration.

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 transformation scheme I proposed, using the micro nuclear reactor as the power source of the aircraft, so as to use the electric engine to provide power for the aircraft. 

"electric aircraft? Is this really possible? " A staff member beside the leader asked Chen Xin.

Chen Xin nodded and showed a drawing to the leader.

"This is the electric aircraft I designed. It uses a 3 megawatt nuclear reactor as power to provide sufficient power for the four engines of the aircraft. "As Chen Xin said, he pointed out on the drawing:" I refer to the famous Osprey helicopter, which also adopts the tilting rotor design, but compared with the Osprey helicopter, the propeller of this aircraft is four, which can provide more lift for the aircraft.  "

" four propellers How does this look like a UAV? " The leader looked at the plane on the drawing and felt that the layout of the propeller was really like a UAV.

Chen Xin nodded, did not hide what he was referring to, and answered positively: "I just refer to the propeller layout design of UAV. It can take off and land vertically like UAV, or take off and jump like Osprey helicopter. When in the air, the four propellers can provide both lift and thrust, which is enough for all kinds of complex rings It's necessary to fly under the environment.

Moreover, this design has one 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.

We don't have to face many technical problems like the Osprey helicopter because of the change of propeller, 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 yun-9 transport plane to enable it to fly normally, but also completed the design of the new helicopter, which was beyond his imagination.

Under normal circumstances, the design of an aircraft can only be completed in a few years at least. It took 20 years for the Federation to manufacture the Osprey helicopter!

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

"What's the performance of this plane?" The leader calmed down, didn't show his emotion on his face, but instead cared about the performance of the plane.

"The length of the aircraft is 20 meters, the maximum wingspan is 16 meters, the height is 7 meters, the empty weight is 16 tons, the maximum take-off weight is 40 tons, the load is 20 tons, the maximum flight speed is 550 kmh, and the practical lift limit is 8000 meters. Because it is driven by nuclear power, its flight distance has no upper limit." Chen Xin introduced the performance of the aircraft in a rather proud tone, and said with pride: "the performance of the aircraft is slightly better than that of the Osprey helicopter, which can carry 12 fully armed special forces soldiers, or carry 2 tons of materials at the speed of 500kmh.Whether it's used in combat, disaster relief, or material transportation, it's perfectly competent. This is the best solution I can think of after referring to the current environmental conditions. After all, conventional engines of other aircraft always have to face the impact of dust in the air. "

When Chen Xin said this, he also motioned to the leaders to have a look at the propeller of Yun 9.

Following Chen Xin's instructions, the leader was surprised to find that Yun 9's propeller was full of scratches and wear marks, which almost covered the windward side of the whole plane.

"If you just fly in the troposphere, it's OK, but if the plane goes into the horizontal flow, a large number of particles and dust suspended in the air will cause great wear to the plane 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 the aircraft skin is made of higher strength materials, which are not afraid of wear and tear, and the engine can ignore the damage caused by dust, I do not recommend any aircraft to fly in the stratosphere. " Chen Xin looked at the leader and said to him solemnly.

After listening to Chen Xin's words, the leader looked at the scratch and damage on the surface of Yun 9. After thinking about it, he nodded his head seriously.
