Chapter 1552: Mushroom plate and balance beam

A large mushroom plate above his head was destroyed by aerodynamics. It is very dangerous to fly. Fortunately, your own large plate does not need to be rotated. If it is rotated, the risk is even higher.
If there is a fall, there are so many experts on this plane. This danger is absolutely unbearable in China.
Now, after hearing Qin Guan's words, Ma Lao looked a little embarrassed: "Yes, the biggest problem with our early warning aircraft is its engine."
Mr. Ma is only in charge of the airframe. The avionics tests above were carried out in the hands of these engineers. From the current point of view, the first problem encountered by this aircraft in flight was the engine.
Yunshi still does not have its own engine. It can only use the JT-3D engine, a spare part of civil aviation. This engine has only 80 kN thrust, which is no problem when used on passenger aircraft. However, after adding a large plate, the resistance Increase, the decline in aircraft flight performance is still obvious.
However, now they have no ability to import advanced engines from abroad, so at present they can only use existing engines to test flights.
In this way, making this early warning aircraft in flight is very dangerous.
Eagle Country’s E-3 early warning aircraft also uses the Boeing 707 body, but they changed the engine to a TF33 with a thrust of 93 kN, which is also a lot more than the original.
Using the original engine is indeed not enough.
Qin Guan heard Ma’s words and immediately promised:
This is easy to solve. Our North Industries Corporation will come forward and buy a batch of CFM56 engines.

In this era, there is already this excellent engine. The original model has a 100 kN level. In this way, the thrust is increased by 25%, and the power is completely fine.
The turbofan engine of the new fighter jet has already begun to be manufactured. Compared with the engine of this passenger plane, only the external duct is different, and Qin Guan has long wanted to exchange part of it.
Now, this matter has just been solved. Five engines have been exchanged. Four of the early warning aircrafts here have been replaced. The remaining one is reserved for engine engineers to study and solve their own power problems as soon as possible.
"Yeah, this is great. We also have this idea. After the CFM56 engine is installed, the power is not a problem at all!" Ma Lao said.
and many more! At this moment, Qin Guan thought of something. Actually, he still had a ready-made plan. At that time, he exchanged the Air Force One of the Eagle Nation. Later, because of confidentiality, he put the plane up. Now, The plane is still in storage. Instead of letting it go through in secrecy, it's better to remove the engine on it.
That plane was also a Boeing 707, but, in order to be used by the President of Eagle Country, the engine was of course replaced. The power is more powerful, which is absolutely okay. In this case, there is no need to exchange it immediately.
After all, it is not easy to find a civilian engine in the cemetery.
In short, no matter what, this matter needs to be resolved immediately, so that next time they take off, they can use a more powerful engine.
"The confrontation at sea fully demonstrates the importance of early warning aircraft. Once our early warning aircraft is successfully developed, it will become the brightest eye of the Air Force." At this time, Mr. Wang also walked over and said, "However, The cost of such a large early warning aircraft is too high for the Air Force to equip it in large quantities."
As one of the persons in charge of the development of early warning aircraft, Wang Lao has a long-term vision. At this time, he is still holding half of the cable in his hand, and has just completed the repair of a piece of equipment.
Qin’s point of view:
Yes, this kind of early warning aircraft is a strategic early warning aircraft. After we have successfully developed it, it will be equipped with three or four aircraft. Then, based on this technology, we can develop medium-sized tactical early warning aircraft to use The C-130 is a body, so it is cheaper to build, convenient for a large number of equipment, and convenient for future export."
After spending huge amounts of money on research, of course, there must be results. If it can be sold, it can be converted into foreign exchange. Moreover, Qin Guan is also very sure that he can definitely sell it.
At present, there are already two AWACS projects in China. The Air Force model here and the Navy model of the North S-3 AWACS aircraft. It is enough to support two models at the same time. It is impossible to make a third model, only the current one. After the early warning aircraft is developed, the team will develop it again.
Although there is already a platform for Yunba in China, Qin Guan is not optimistic about this platform. Last time he extorted a batch of C-130s from the Eagle Country, the Air Force was full of praise. Therefore, Qin Guan hopes to copy this one. The platform has become the main force of domestic transport aircraft.
On its basis, research on tactical early warning aircraft can be equipped with a large amount.
If the surveying, mapping and copying of the C-130 transport plane is not smooth, it is completely fine to use the Yunba platform.
Hearing Qin Guan's words, Mr. Wang nodded: "This is okay, but we are not very familiar with the aerodynamics of this kind of aircraft. If we change it rashly, it will easily cause danger."
Our own airplanes have all undergone repeated wind tunnel experiments, and the mastery is very good, but if you want to use C130 to change it, it is not clear.
"This is easy to solve." Qin Guan said: "As a low-end machine, we can build a balance beam."
Thinking of this, Qin Guan kept talking again.
In terms of early warning aircraft, everyone can be equivalent to a mushroom plate on the top, but in fact, not all early warning aircraft are like this. Some early warning aircraft have a big stick on it, just like a stick. Wood, so it is called a balance beam.
This kind of big rod is parallel to the fuselage, which has little aerodynamic damage to the aircraft, and at the same time the air resistance is also very small.
"Balance beam?" Everyone doesn't know what Qin Guan is talking about, and now, Qin Guan is definitely an expert-level figure in it.
"In the past, our radar antennas were all circular, but this was only determined by the previous technology. When we develop into phased array radar, we should know that it is not necessary to make the antenna circular. For example, now, our large plate has a circle on the outside, but in fact, there are only three equilateral triangle antennas on the inside, right?"
Everyone nodded. If compared with E-3, it seems almost the same. However, on the top of E-3 is a huge flat-panel slot antenna, just like a super-amplified version of Tomcat radar. The inside is composed of small components, and there is a big difference between the two.
However, when Qin Guan didn't listen to his report, he said that there were three phased array radar antennas inside. That was beyond their expectations. President Qin really expected things like a god, as if he had a perspective eye. .
"However, how can it change, can it become a piece of wood?"
"Why not?" Qin Guan said with a smile.
