188. Prepare Before Bidding, Let You Score A Score, And Still Crush The Victory!
Song Wenhao, general manager of Longguo Commercial Aircraft Company, has been very busy recently.
Busy holding bidding activities for the new 1919 engine for domestic commercial large aircraft.
In fact, he already knew the test results of the new aeroengine from Fang Yingrui.
He knows that in this bidding, Han Yue and the Aviation 501 Research Institute develop new aero engines, and will undoubtedly defeat Rolls-Royce and General GE and win!
All technical parameters are completely crushed!
Song Wenhao had never seen such a perfect aero engine.
It can reduce aircraft operating costs by 50%.
What a terrifying improvement is this?
By then, the I919 equipped with a new engine will cause a bloody storm among single-aisle small passenger aircraft around the world.
It absolutely crushes Boeing’s 737MAX and Airbas’ A320neo.
Precisely because Han Yue and Aviation 501 Research Institute are sure to win this time, they must do their best in the bidding process so that Rolls-Royce and GE cannot find any faults!
That is, in the bidding process.
Longguo Commercial Aircraft wants to pull a bias, but not towards the new aviation engine of the Aviation 501 Research Institute and Han Yue.
Even if the process is biased towards Rolls-Royce and General GE, there will be nothing to say if they lose.
Let Han Yue and the Aviation 501 Research Institute win frankly and without any dispute!
Otherwise, if Rolls-Royce or GE become dissatisfied and start a quarrel, saying that Longguo Commercial Aircraft Co., Ltd. is engaging in shady activities, it will be ugly and may even affect Long GuoComac's international market.
Song Wenhao put a lot of effort into the bidding process.
The favoritism towards companies such as Rolls-Royce, GE, and Psiphon is mainly reflected in aerial testing.
The process of comparing several aero-engines is mainly completed on the ground.
Various technical parameters are mainly tested on the ground.
Mainly because the 1919 aircraft was designed based on the LEAP engine,
Changing the engine of an airplane is not a simple matter. It does not mean that you can fly into the sky just by replacing the engine.
The most obvious example is the B737MAX aircraft of Boeing Company.
The B737 series was the first aircraft to fly in the 1960s. The body structure is relatively backward, especially the landing gear is very short. The space between the aircraft wings and the ground is very small, and there is no way to install larger aero engines.
The most obvious difference between the B737 aircraft and the A320 aircraft is that the two engines under the wings of the B737 are flat and slightly oval.
This is also hampered by the landing gear. The only way is to change the shape of the engine and flatten it to install a larger aeroengine.
But by the time of the b737-800, it had reached its limit. Even if the engine was flattened, a larger engine could not be installed.
Competitor Airbus's A320 has much higher landing gear and larger space. After the LEAP engine was successfully installed, the operating cost is far lower than that of all B737 aircraft models.
Boeing Co. cannot sit still.
But I am reluctant to give up the cheap and easy-to-use platform b737.
We can only continue to take advantage of the situation, compress the LEAP engine to the flattest position, and then move the engine installation position to the front of the wing and raise it as high as possible.
After such a cool operation, the short-legged B737 can finally be equipped with an advanced large-size LEAP engine.
But a new problem has arisen. The new engine installation position will cause the aircraft to further automatically raise its head when flying at a high angle of attack, causing the aircraft to enter a stall state.
To solve this problem, Boeing added a new system called MCAS (Maneuvering Characteristics Augmentation System) to the 737-MAX series, which enables the aircraft to "automatically lower its head" when necessary.
But this software that automatically bows its head has a big problem.
The fault tolerance rate of this system design is too low. As long as there is a sensor for measuring the angle of attack to provide data, it will start to press the nose. This means that as long as one sensor is broken, the consequences will be very dangerous.
What's even more frightening is that in order to reduce costs, Boeing programmers wrote this software.
It's better to die than die. You can ask the third brother to program.
The third brother brags, makes ppts, and forms cliques. He is the best among the best.
If you ask them to write code, you are really worried that your plane will be too safe!
Then there was a bug.
The B737MAX aircraft suffered several air crashes in a row, causing hundreds of people to die in the sky.
All B737max aircraft around the world are grounded, and the B737max built by Boeing cannot even park on the tarmac.......
In this wave, Boeing almost died suddenly.
Relying on the blood transfusion from Yingjiang Military, the group was able to survive.
After all, Boeing is the eldest son of the United States.
This incident fully illustrates the difficulty of replacing the engine of an aircraft, and it cannot be done casually.
Therefore, bidding tests must be conducted on the ground.
But... Rolls-Royce and General GE are using mature engines, which means they have civil aircraft that can adapt to the bidding engines.
Air testing is available.
In other words, companies such as Rolls-Royce, GE, and Psiphon all have an aerial test link.
However, Han Yue and the Aviation 501 Research Institute have just successfully developed the aeroengine and have not yet adapted it to civil aircraft.
Therefore, the engine developed by the Aviation Institute 501 and Han Yue cannot be tested in the air.
The Aviation 501 Research Institute cannot get this part of the score.
This aerial test is what Song Wenhao calls partiality to foreign engine companies.
Save them from saying that because there is no aerial test, Longguo’s domestic engine can win.
Based on the technical parameters provided by Fang Yingrui, Song Wenhao had gone too far.
Even the domestic engine developed by Aviation 501 Research Institute and Han Yue failed to score a single point in the air test, and the remaining scores in other projects were enough to crush Rolls-Royce and General GE.
So what if we give you an aerial test? We will win in the same way!
On the other side, Fang Yingrui led his team and went straight to Zhonghai Vocational and Technical College after getting off the plane.
He hasn't seen Han Yue for a long time, and he still misses her a little.
He wanted to see what new thing Han Yue was working on.
He didn't care about the aero-engine at all, as if he didn't design it.
Everyone immediately participated in the bidding, and it didn’t even have a formal (money good) name. The new civil aviation engine was always called this.
This is too outrageous.
This is an engine that can change the aviation industry around the world, but it is so ignored. It's really outrageous to be so careless!
Fang Yingrui came to Zhonghai Vocational and Technical College in an aggressive manner.
Go straight to the experimental building.
At this time, Yue Zheng was leading a group of professors from Huaqing University to study graphene batteries.
He didn't even notice Fang Yingrui's arrival.
Fang Yingrui became more and more excited as she listened to Han Yue explain the various advantages of graphene batteries.
A slap on the thigh.
".~This battery is very good for use in the military field! Submarines, satellites, and missiles all need such high-performance and high-safety batteries!"
Only then did Han Yue realize that Academician Fang Yingrui was here.
He smiled and said: "Academician Fang, you are right, this battery can indeed be used in the military field.
"In other words, this battery is suitable for all fields! Wherever electric energy needs to be stored, our new battery is needed! It will completely replace lithium batteries!"
