PS: the hero of East China fell ill again in this chapter. I was going to introduce it a little, but the chapter came out. Alas, this is not good for old military fans. If you feel boring, please ignore this chapter.
Air cooling and liquid cooling are different forms of engine cooling. As the name suggests, air cooling uses air cooling, while liquid cooling uses coolant. Now it is generally water.
The original engines were air-cooled. This engine has some advantages.
For example, the weight is light. Compared with liquid cooling, it has less water jacket and less cooling water tank. As long as the heat sink is arranged outside the cylinder barrel, it will reduce a lot of weight than liquid cooling.
At the same time, because the liquid cooling system is omitted, a troublesome thing is omitted from the whole engine, and the overall reliability is improved.
At the same time, in an air battle, the other side killed the cooling water tank with one shot, and the liquid-cooled engine was scrapped, while the cylinders of the air-cooled engine were scattered on a circumferential plane, which reduced the possibility of being end-to-end by one pot.
However, the mainstream now is liquid cooling, because air cooling has some congenital defects.
The first biggest defect is the cross-sectional area.
The aircraft needs to fly. The larger the windward area, the greater the air resistance. The liquid cooled engine has a small cross-sectional area, while the air-cooled engine needs to arrange multiple cylinders in a plane with a large cross-sectional area, which finally leads to the increase of the air resistance of the whole aircraft.
At the same time, the arrangement of air-cooled aircraft will cause more obvious and violent vibration than liquid-cooled aircraft, which will undoubtedly affect the aircraft.
Moreover, since the air-cooled engine uses heat sink or directly exposes the components to the air for cooling, and the heat sink can not be increased indefinitely, in terms of heat dissipation, the air-cooled engine is worse.
In the history of aircraft research and development, air-cooled engines often have a headache for heat dissipation. If not, the engine will catch fire, while liquid cooled engines do not have this concern.
In fact, there is no final conclusion whether liquid cooling is better or gas cooling. In World War II, many ace fighters were born, including gas cooling and liquid cooling.
For example, the zero war Nakajima "Rong" 21 star air-cooled piston engine and the cat's r1830 star air-cooled piston engine are the peak of air cooling.
The "Merlin" 12V liquid cooled piston engine of flamethrower I, the db601 liquid cooled piston engine of BF109, the Allison v1710-33 liquid cooled piston engine of 40, and the mikulin am-35 liquid cooled piston engine of IL-2 are excellent liquid cooled engines.
Whether air-cooled or liquid-cooled, as long as you can win, it is a good plane!
From the actual situation in Germany, although the db601 is excellent, the output is limited. Now Goering has put on a posture. It is obvious that he will never give it even if he quarrels.
Just start a new stove!
At the same time, from hilrick's point of view, it is more appropriate for the navy to use air-cooled engines. For example, just look at the United States on the other side of the ocean. The U.S. Army aviation team uses liquid cooling engines, while the navy is all air-cooled.
Why? Troublesome maintenance, poor anti Strike ability!
Liquid cooled engines have coolant. If the weather is cold, when starting the engine, it is necessary to fill in boiling water in advance to preheat the engine. Once there is water leakage, it is a headache. Therefore, in cold areas, liquid cooled engines are difficult to serve.
When Germany invaded the Soviet Union, the dispatch efficiency of BF109 was less than a quarter of that of fw190. That's why.
Air cooling is not so troublesome. It can be ignited directly at any time! On the aircraft carrier, far from the mainland, there is not much fresh water on the warship. If you have to prepare for the aircraft, it will be a nightmare.
Moreover, air cooling has strong anti Strike ability. In battle, once it is hit by a cylinder, it may still fly back. If it is liquid cooling, it will have to parachute.
On land, parachuting and the ground. Then, at sea, jumping into the sea is almost like suicide.
Although the windward area of air cooling is large, it can be alleviated through superb design. For this, Shrek trusts Fokker Woolf company very much.
Because this is what happened in history, and the final fw190 is more advanced than the performance of BF109!
In history, Germany looked around the world and found that only one BF109 beat the world, which was quite dangerous.
Because at least two modern fighters from other air force powers are about to be put into service, Germany has put forward the technical specifications of new fighters in 37 years of history.
In the spring of 38, these technical specifications were sent to major manufacturers in the hope that advanced fighters would be born among them.
According to the scheme, Fokker company designed a compact fighter driven by star air-cooled engine.
However, at that time, the German executives were supporters of in-line water-cooled engines and did not recognize the Fokker company's new fighter plan. Therefore, this plan did not enter Goering's eyes at all.
However, Henkel HE100 and he112, which Gorin had high hopes for, failed to develop. At the same time, although junks in Dessau and Daimler Benz in Stuttgart were at full power, they could not provide enough liquid cooled engines for aircraft production in the short term.
As a result, Henkel had to greatly reduce and finally stop the production of he111p bomber with db601 engine and focus on the production of he111h driven by junks' jumo211 engine.
As a result, just like the hidden flowers of BF109, fw190 finally re entered the eyes of the German air force.
The Fokker company is also very successful. This kind of aircraft is finally developed, and it is even better than BF109!
As for the problem of large upwind area, it was also skillfully solved by the designer. The engine cooling air inlet was designed in the engine hood and covered by a special fairing of ducted propeller hub. This design not only increased the cooling air flow, but also reduced the air resistance.
Now, because of the passage of Chirac, history has changed again. This fighter that almost died in history will enter active service earlier!
"I suggest that the Navy should raise funds by itself, select a manufacturer and use the air-cooled engine of BMW to develop a shipborne aircraft suitable for the Navy." "I personally suggest that Fokker company can be invited to design. The most basic indicator is to surpass BF109 in an all-round way," hirek said
Goering opened his mouth. Although he didn't say it, his eyes betrayed him. In that way, it was clear that he was saying, are you bragging, Shrek?
Please report us if you find any errors so we can fix it asap!
