Which country's aircraft in World War II? Good motivation

1. The jet engines of the United States and Germany had no advantage over the British engines at the same time, and the piston engine was the most widely used in World War II. In this respect, Germany was not only far inferior to the United States, but even had no advantage over the Soviet Union.

2. If it is an airplane engine: I personally think it is such a ranking of Britain, Germany, the United States and the Soviet Union.

3. The UK is better. Germany has a high failure rate and a short lifespan of the engine due to the lack of raw materials.

4. As early as four years ago, the German authorities ordered the Meserschmitt Aircraft Factory to develop a new type of fighter that could be compatible with the turbojet engine tested by Bavaria or Juncker as soon as possible.

Because once the mixture of air and gasoline is compressed too hard, the mixture will burn in advance before ignition, resulting in a burst cylinder. So this is the main reason why diesel engines have higher thermal efficiency than gasoline engines. Of course, there are some secondary reasons, which will not be described here.

Diesel is cheaper than gasoline. Fuel is the blood of tanks, and diesel is much cheaper than gasoline, but the combustion efficiency is not low at all. This is a great advantage of diesel applied to large equipment.Using diesel is more fuel-efficient and efficient than gasoline, which is the biggest strategic advantage. Diesel is safer than gasoline.

In fact, I have summarized the reason why German and American tanks all use gasoline engines. First of all, gasoline engines developed earlier than diesel engines. So the technology is more advanced. There is no other way. Although Diesel's diesel engine is relatively mature, it loses to gasoline engine in the competition of small cars for home use.

World War II... Mainly gasoline, Soviet tank diesel, gasoline engines are easy to make, and the vibration noise is small. Germany and the United States use gasoline engines. The main problems are that the requirements for diesel engines are a little higher. At that time, there were no suitable ones in Germany and the United States. The diesel engine technology was immature, and the fuel consumption was high.

German tanks in World War II were mainly gasoline.Because there is no oil field in Germany, gasoline can be produced by coal catalytic cracking, which is very important during the war. Diesel can improve the anticoagulation effect by adding anticoagulants. The tank is frozen, which is basically not caused by the freezing of the fuel. The biggest factor is the walking mechanism and the water tank.

Is World War II aircraft engines stronger than the United States or the United Kingdom

1. The United States, Germany's jet engines have no advantage over the British engines, and the most widely used in World War II is the piston engine. In this regard, Germany is not only far inferior to the United States, but also has little advantage over the Soviet Union.

2. If it is an airplane engine: I personally think it is such a ranking of Britain, Germany, the United States and the Soviet Union.

3. It is also worth mentioning the P-51D "Mustang" fighter of U.S. Land Air. Although the fighter uses a British liquid-cooled engine, its escort capacity is second to none over Europe. It has many advantages such as long range, strong firepower and good mobility. It is a B-17 bomber. The best escort fighter.

4. Germany's Fw190 and Me109 are also excellent aircraft, and Britain's fire is also a momentary choice, but there is still a big gap compared with Mustang. The non-strategic bomber that tests a country's aviation industry the most.

5. Britain is a traditional naval power, but its over-reliance on natural barriers in the Atlantic Ocean has led to the shrinkage of its army power. Due to the impact of the economic crisis at that time, a large part of its economic and resource maintenance came from the support of the colonies and the United States.

6. Germany: Participated in the joint production of the EJ-200 engine (English, German, Italian and Western) produced by the four countries. Although it is jointly developed by the four countries on the surface, most of them are due to the British company Luo Luo, so the level of the German engine is estimated to be lower than that of France. Japan: It has been using American engines, and its level is imaginable.

Seeking for some information about the American J-33 jet engine during World War II

1. The J-33 stamping jet engine is currently divided into three categories: subsonic speed, supersonic speed and hypersonic speed. The subsonic stamping engine is fueled by aviation kerosene, adopts a diffusion-shaped intake duct and a converging nozzle, and the supercharging ratio during flight does not exceed 89. It generally cannot work when the Mach number is less than O.5.

2. Including turbojet engines, turbofan engines, turboprop engines and turboshaft engines, all have compressors, combustion chambers and gas turbines.

3. Whittel. Whittle, a British inventor, invented the aircraft jet engine. The emergence of jet engines has brought a revolution to the world's aviation industry. Because it adopts a new working principle, Whittle was born in Coventry in southern England on June 1, 1907.

Why are most of the engines of naval fighter aircraft in World War II air-cooled

1. What the two people upstairs said make sense! ~~But it's just about the cooling system of the engine (although this is the main one)~~ Use water coolingThe engine of the system, the cylinder overlaps, and there is a protective cover between the engine and the propeller, so the engine cross-section is relatively small and the wind resistance is small. If it is an air cooling system, adding a protective cover is not conducive to heat dissipation.

2. First of all, it can avoid the leakage of coolant and ensure the safety of equipment operation; secondly, in some harsh conditions, such as deserts, air cooling technology is more suitable, because water resources are relatively scarce.

3. Maintainability and damage resistance: Needless to say, the air cooling is good. Even if several cylinders are broken, it will not affect the pilot to fly back.

4. In fact, before World War II, the strongest countries in the world's fighter jet development were Britain and Germany, which launched Spitfire and ME-109 respectively. Both fighters used liquid-cooled engines.Compared with air-cooled engines, liquid-cooled engines have more advanced technology. Their size is relatively small, and the installation can reduce wind resistance to the greatest extent.

5. There are mainly two types of star piston engine (air cooling) and V-type engine (water cooling), and there are relatively few other types. Among them, the star type is used more often on aircraft carriers. Air-cooled logistics is much more convenient than water-cooled, which makes the aircraft's combat attendance rate higher.
