What is the principle of the engine of the B2 stealth bomber

4 sets of General Electric F118-GE-110 afterburnerless turbofan engines, each with a maximum thrust of 1,000 N. Installed in pairs between the outside of the ** cabin and the wing structure, chlorofluorosulfuric acid is sprayed into the exhaust to eliminate the visual wake of the engine.

The B-2A bomber is equipped with four F118-GE-100 turbofan engines produced by General Dynamics of the United States with a thrust of 1,000 Nn (19,000 pounds).

A gas turbine engine in which the gas discharged from the nozzle and the air discharged by the fan together produce a reaction thrust. A turbofan engine consists of a fan, a compressor, a combustion chamber, a high-pressure turbine that drives the compressor, a low-pressure turbine that drives the fan, and an exhaust system.

The compressor, combustion chamber and high-pressure turbine are collectively referred to as the core engine, and part of the available energy in the gas discharged by the core engine is transferred to the low-pressure turbine to drive the fan, and the remaining part is used in the nozzle to accelerate the exhaust gas.

Four GE FF-118 engines, rated at 8,618 kg of static thrust, were installed in the engine compartments on either side of the B-2A** fuselage.

The F118 was developed on the basis of the F101-X, a fighter model with the F1 engine of the B-1 bomber. Compared to the F101, the F101-X has a smaller low-pressure culvert casing, reducing the bypass ratio from 2:1 to:

1。The low-bypass ratio engine required only a smaller intake and exhaust system, so it was chosen by the B-2. The engine air intakes are located away from the leading edge of the wing to avoid being hit by radar waves from below.

Due to the thick wing structure, the B-2 could bury the engine deep inside the wing, and the flat air intakes and curved air intakes on the upper surface of the wing could ensure that the airborne radar could not directly irradiate the front of the engine from above, and even less from below. In this way, the B-2 can use a simpler air intake, and only need to have the tines on the lip without any problems.

Why is the B2 bomber called a "ghost"? In addition to stealth, this ability is even stronger!

According to relevant data, the expenditure is more than 100 million yuan. But the range of his blow is very close. And he has good stealth and can form effective strikes.

But he's too expensive. Not every country can afford it. If you choose.

I wouldn't choose B2 for long-range bombing. I would choose a long-range bomber like some Russian Tu-22MS.

It was designed using biomimicry bats.

I think it's like a fish, but I don't know what it is. I saw it when I was shopping for groceries at the mall, if I didn't want the tail of a fish.

The B2 stealth strategic bomber of the United States has always occupied the first position in the world with absolute superiority since it entered service, and China has been seeking to break through the technical difficulties of long-range strategic bombers, and no longer let our "grandfather" H-6 fighter become a joke of other countries.

The 21 bomber and the B2 bomber are similar in appearance, still using a tailless flying wing aerodynamic layout, but according to the United States, this bomber is still different from the B2, not only more advanced in performance, but also simpler in appearance than the B2.

It is simpler than B2 in terms of appearance. This bomber will not replace the B2 bomber, but will replace the B52 and B1B bombers, fighting alongside the B2 bomber.

B2 is the most powerful bomber in the world, there is no one", and the reason for this is that it is forced out because these are forced.

Its technical content is very powerful, and it has always been a leader.

Because it can still escape most of the radar detection.

Strategic needs. The B2 is mainly used for strategic nuclear strike missions, but of course it can also be used for conventional strike combat missions (but the cost is much higher than that of ordinary bombers). The "Trinity" nuclear strike capability refers to:

It has three launch platforms: air-based, land-based, and sea-based to carry out nuclear strikes. Perform conventional strike combat missions with other more suitable equipment; As for the implementation of strategic nuclear strike missions, countries generally tilt towards land-based and sea-based - land-based, the development of vehicle-mounted mobile nuclear weapons; Sea-based, the development of more advanced strategic nuclear submarines. At the same time, the development of multiple warheads and other technologies to improve the penetration capability.

Moreover, the B2 aims to achieve a "global strike capability", which is the result of the US strategy**. Other countries do not have this kind of strategic needs, so they naturally do not need this kind of **, that is, there is no need to develop similar equipment, which is the most important reason, there is no one.

Technical issues. Any advanced equipment has its advanced design concept, science and technology, manufacturing process and so on. There is no doubt that B2 has all these advanced things, and countries that are slightly less powerful will not be able to develop them at all.

For example, after the F22 and F35 entered service, many countries around the world began to develop fourth-generation aircraft. However, as of today, only China's J-20 has entered service, Russia's Su-57 has produced 12 aircraft, China's J-31 is still in the research and development stage, and other countries such as Japan have declared failure. The technical difficulty of the B2 is higher, and there are no more than two countries in the world that have the strength to develop similar equipment (except for the United States).

The commander of the Chinese Air Force has also confirmed: The H-20 is not a strategic stealth bomber like the B2.

Because so far there have been no major breakthroughs in the field of bombers.

The B2 bomber used a variety of precision-guided bombs, ground-penetrating bombs, and nuclear **.
