The last prize can be said to be a surprise for Mu Feng.

The turbofan 19 vector version is a fourth-generation medium-thrust engine, and the turbofan 15 is a generation, which should be included in the scientific research system.

In the ordinary loot lottery, I directly drew the drawings for production, or the full version with a vector spout.

And it fills the gap in its own aero-engine puzzle.

Modern fighters are basically divided into three orders of magnitude: heavy, medium, and light.

Aero engines are basically divided into three orders of magnitude: large thrust, medium thrust, and small thrust.

Heavy aircraft use double thrust, such as J-20, J-15, F15, F22, Su27, Su33.

Heavy aircraft may use dual medium thrust, such as F18, MiG-29, Rafale, Typhoon, or single large thrust, such as J-10, F16, F35.

Light machines generally use a single push, such as the FC1 Thunder, JCS-39 Gripen, LCA Brilliant, and Phantom 2000, and some use a double push, such as IDF.

Mufeng already had three engines before: turbofan 15 vector version, turbofan 10B, and turbofan 10B vector version, but all three of them were big pushes.

Now with the mid-thrust turbofan 19, the vacancy of the medium-sized engine is filled, and medium-sized and light fighters can be designed around this engine in the future.

The aircraft used for the upgrade of the Liberty Ship Niang aircraft carrier of the headquarters does not need to be specially developed engines.

However, they can't be allowed to do it in one step, and the vector spout should be removed the first time and the normal version should be used.

Mu Feng counted his income with a very happy mood.

More than 600 lotteries, two kinds of total resources of about 30,000 each, 8,000 scientific research points, and three soul cores.

The number of system cores in Mufeng's reserve has reached 9, and the number of ordinary cores has reached 85.

Looking at the number of cores, Mu Feng suddenly thought that he had indeed not built for a while.

Now is the time for a shortage of people, and it is time to resume daily construction in the future.

It's night now, and peace has slept, so it can only be built tomorrow.

Mu Feng adjusted his mood and entered another lottery interface.

Two deep-sea flagships with 300 high-class loot and three draws.

According to Mu Feng's experience, the high-level loot lottery, if it is resources and points, is at least 10,000.

If it is equipment, it is basically in the scientific research system, and except for the complete and large pieces such as the J-20, the general equipment is basically directly given to the drawings.

All in all, it's all good stuff.

Mu Feng took a deep breath, rubbed Heping's buttocks, and clicked on the first draw.

"Obtained: GT50000 Gas Turbine Design Drawings."

Domestic gas turbines are actually one thing, but there may be two names.

China Shipbuilding Industry Co., Ltd., which belongs to the ship's mouth, has an internal name that GT25000 this model.

AVIC, which belongs to the aviation port, has an internal name of QC280.

GT25000 and QC280 are actually the same thing, and the names of the two manufacturers are different.

Mu Feng looked at this reward, and his first reaction was a little disappointed.

Then I took a closer look at the instructions, and suddenly came to my senses again.

GT50000, a large marine simple cycle gas turbine with a rated power of 50,000 kilowatts, equivalent to 68,000 horsepower, and a thermal efficiency of 40%.

Looking at the power alone, it has been 10,000 kilowatts more than the GT25000IC I used before, and the power has increased by a quarter.

The point is, GT25000IC is a complex loop, and the new GT50000 is a simple loop.

It is equivalent to one opening the skill, and the other is just a flat cut, and the damage of the flat cut is higher.

After adding IC cycles to it, the power may increase to 60,000 or even 70,000 kilowatts.

Even in the ordinary version, only two are needed to make a 40,000-ton battleship run to 30 knots.

Of course, for their own fleet, more power does not necessarily mean that it can run faster, but more that it means that the electromagnetic gun can have a higher rate of fire.

Mu Feng kept the new steam turbine drawings in good place and continued with the second draw.

"Obtained: 'Three-Five' medium and short-range anti-aircraft missiles."

Mu Feng looked at the name and was a little puzzled, so he clicked in and took a look at the introduction:

"Three Five" is just a nickname, derived from its "Three Five" design standards, that is, 5 times the speed of sound, 50G overload, and 50 km range.

The universal vertical launch system used by 052D and 055 has the ability of "one pit and four bombs", which is mainly used to install medium and short-range anti-aircraft missiles.

Originally, there was a DK10 medium and short-range anti-aircraft missile whose size met the requirements, but the navy had a high vision and was a little disdainful of the DK10's performance data.

It was required to develop a new one according to the "three five" standards, so there was a "three five bombs".

"Three-five bombs" belong to the fourth-generation anti-aircraft missiles, the top goods among medium-range anti-aircraft missiles.

With the "three or five bombs", together with the long-range Hongqi-9B, the short-range Hongqi-10, 1130 close-in defense systems, and the PLAN fleet air defense missile system, it can be regarded as a real consummation.

For Mufeng, three or five bullets should be said to be the icing on the cake.

Most of their enemies are still propeller aircraft, and their own DK10 can not be used very much, let alone three or five bombs with higher standards.

But since there is a better one, Mu Feng will not waste it, and he will decide immediately, and he will replace all his capital ship girls when he turns around.

Moreover, with more generation differences, I have more choices, which can be upgraded or exported to the ships of the headquarters.

Mu Feng exhaled, looked at the last 100 high-grade loot, took a deep breath and ordered.

"Acquired: FC31 Fighter Demonstrator Version 2.0."

Looking at this reward, Mu Feng's mood was a little complicated.

The FC31, nicknamed the Falcon Eagle, is the second fourth-generation aircraft of China's own design.

The J-20 is a heavy fighter with a canard wing layout with two high-thrust engines, and the FC31 is a medium fighter with a conventional layout with two medium-thrust engines.

The J-20 is a prefix for the word J, while the FC31 is not a prefix for the word J.

The reason is also very simple: only fighter planes that have been recognized by the General Armament Department and officially entered the equipment sequence of the Navy and Air Force can have an official name with the prefix "J".

This is equivalent to going to the account.

Similarly, the air defense missiles for self-use are "Red Flags", the ones that are exported can only be called "DK", the anti-ship missiles that are used for their own purposes are called "Eagle Strikes", and those that are exported are all "CM".

The J-20 was organized by the General Armament Department and won the competition for the fourth-generation aircraft project of the Air Force, and was designed and produced as an official project of the country and the Air Force.

So from the very beginning, he directly entered the equipment sequence, and before he was born, he had a household registration called J-20.

The FC-31 Falcon is an enterprise project funded by AVIC Corporation after the failure of the bidding in order to maintain the scientific research capability of the institute and with the purpose of striving for the foreign trade market.

Therefore, the Falcon cannot be named with the prefix "J" for the time being, but like the FC1 Thunder, it takes the name of an export version of the fighter that starts with FC.

If the Falcon is accepted by either the Air Force or the Navy in the future, and enters the PLA equipment sequence, there will be a new official account.

At that time, it may be called J-31, or J-21, or J-25 and J-35.
