Chapter 815: F110 engine

Compared with military aircraft, civil aviation passenger aircraft values ​​safety the most, and there is nothing wrong with using a mature engine.
In China, among the self-developed engines, only Spey is mature, but Spey’s engine is too bad. Its civilian model is the engine used in the Trident airliner of civil aviation, with only more than 40 thousand. The power of cattle is more than 80 kN.
That is to say, for your own transport ten, four engines are hung under the wings. If the Spey is used for civilian use, eight engines are enough. Although the more engines, the safer it will be. The mechanical complexity is great.
Mr. Ma nodded: "I look forward to the success of our own three-generation engines. After being transformed into a civilian model, the performance of our passenger aircraft will definitely improve greatly."
The current JT3D engine is actually a turbofan modified with a turbojet engine. The fuel consumption rate of this engine is not low. If it can be replaced with a new type of engine, it will be more fuel-efficient, it is definitely the best.
Ma Lao has full confidence in the future.
As Qin Guan and Ma Lao said, they turned around the plane and watched the plane undergoing final assembly. They learned that the first plane had completed the final assembly and was undergoing static tests. The second plane was ready for a test flight. , And the materials for Unit 3 have already been prepared.
The fate of the future generations of the materials of the third machine is embarrassing. Because the project was discontinued, the aluminum plate of the third machine was actually used by a group of workers to train the rivet gun. They wanted to assemble the rear fuselage of the McDonnell Douglas 82, which was so speechless. what.
"When the first flight arrives, be sure to notify me." Qin Guan said to Ma Lao: "I very much hope to see the moment this plane takes to the sky. It's getting late, so you can rest early."
This visit, it has been more than ten o'clock in the evening, in the factory, the workers are still working hard, which makes people very moved. For the construction of the motherland, these hard-working workers have left their homes.
"President Qin, shall we return to the capital?" Xiang Jing asked Qin Guan.
Qin Guan shook his head: "No, let's go to the 4430 factory first."
Qin Guan thought about the engine problem again. Now, Spey’s remodeling, I don’t know how it is going. The new third-generation engine project should also be launched. Time is not waiting!
Qin Guan is full of historical urgency.
It can't solve the problem of power, the problem of the heart, everything is in vain, even if Spey does it well, it only solves the problem of existence, and the new third-generation engine is the most critical.
During the flight of the plane, Qin Guan plunged into the system. Now, he needs to find some design materials.
Weapon data cemetery, start!
The screens flashed one by one, and the newcomer Chongzhen was dumbfounded, almost replacing Lisa's position, and asked Qin Guan about this and that. Qin Guan ignored the follower and clicked each button to enter General Electric company. What Qin Guan was looking for was, of course, the development materials for the F110 engine. In later generations, as the fourth-generation military engines have begun to be equipped, the thrust-to-weight ratio of the F119 engine, which is guarded against the sky, has reached 10, giving the F22 extremely excellent performance. Therefore, the F110 The technology of such three-generation engines has been sealed up and entered the weapon data cemetery.
Qin Guan only needs to find it.
How much information is there for an engine? At least dozens of tons!
Qin Guan was looking for this engine while recalling it.
It is not easy for Eagle Country’s company that develops fighter aircraft power to develop a new engine. This F110 engine dates back to the 1960s, when the code name was F101.
This is a medium bypass ratio afterburner turbofan engine developed by General Electric for the strategic bomber B-1. At that time, the company was implementing the second-generation advanced turbine engine gas generator program under the Eagle State Air Force contract, numbered GE9.
After the successful competition, a long period of research and development began, and it took ten years to pass the experiment in 1976.
It's a pity that Carter came to power. This president is absolutely an alien. It can be said that he is a president who was blasted down in the history of Eagle Nation.
Carter stopped the plan, thinking that the B-1 bomber was too expensive, and the B52 was enough.
However, this engine is still continuing to experiment, and the F101-GE-100 test plan continued until 1981 to accelerate the maturity of the engine, extend the life of parts, and reduce production costs and logistics support costs. Finally, the ground test accumulated more than 40,000 hours, and the flight test accumulated 7,600 hours, and the engine reached a level that can be put into use. The total development cost is 621 million eagle yuan.
After that, they keenly foresee the opportunity. At this time, the TF30 and F100 engines used by the Eagle Country's first-line fighters had a lot of durability, reliability and maneuverability problems. General Electric began to modify this engine. After all, it used to be The power of the bomber can be said to be similar to that of the passenger plane. Now it needs to be changed to become the power of a fighter jet.
Harmony shows the benefits of Xinjiang, as long as the outside world is changed.
The improved code name is F110. Compared with the original F101-GE-100, this engine mainly reduces the bypass ratio and improves the supercharging ratio.
The fan was changed from stage 2 to stage 3. The pressure ratio was increased to 3.2, the diameter was reduced to 970mm, and the bypass ratio was reduced from 2.01 to 0.87; to adapt to the increase in the speed of the low pressure rotor, the low pressure turbine was redesigned; to meet the requirements of fighter maneuvering flight, The design overload has been increased to 10; the control system has been improved and a backup device has been added; in order to adapt to the body of the F-14, F-16 and especially the F-15 aircraft, necessary external dimensions, pipelines and anti-icing systems have been made Modification; Finally, it is easy to overlook that in order to reduce weight without sacrificing durability, weight reduction measures have been taken for almost all components and systems other than the core machine.
After this series of improvements, the first generation of famous aircraft finally appeared and became the typical engine of the third generation.
The aero engine is the crown jewel of industrial products. Even if it is the imitation of this engine, it will go through various tests, and it must continue unswervingly. Now, it is necessary to exchange all the data of F110 and F101. Mr. Wu and they sent it!
Qin Guan quickly found it.
There were almost a mountain of materials. Looking at these materials, Qin Guan frowned. If these materials were exchanged, where would they be exchanged?
If you are at the head office, you have to transport it. If you are at the 4430 factory, it would be too risky.
At this moment, a voice came from the sky: "In addition to paper materials, aren't there other materials stored on computers? The CDs there are used as backup materials?"
Suddenly, Qin Guan was happy. CD backup was a very common method for later generations. It just so happened that he developed the CD system again, and it was much easier now!
