Red Soviet Union

? However, the key to this, of course, is this variable cycle ramjet engine!

If some structures of the engine can be deformed so that it can work in different engine forms such as turbofan, turbojet, ramjet, etc., then it is called a variable cycle engine. This engine is normally a turbofan engine with a low bypass ratio or a turbojet engine with an external bypass. Only in this way can the thrust demand of the aircraft be met during take-off, and as the speed increases, the front fan of the turbofan will stop operating and adjust to the lowest resistance situation and close the external duct to become a turbojet engine. After the speed is high, the resistance of the turbofan engine is very large, and the advantage of the turbojet is obvious. And when the speed increases again, the air intake of the turbojet engine will also be closed and start the outer duct, and ignite at the end of the outer duct to become a ramjet engine.

In this way, a single engine can have the performance advantages of three types of engines: turbojet engine, turbofan engine and ramjet engine, adapting to various situations from low-speed flight to hypersonic speed.

So far, the only J58 engine that has been put into practical use is the J58 engine used by the Blackbird, which has outstanding performance advantages. However, such an engine is very complex and at the same time expensive.

And the Soviet Union wants to have supersonic aircraft, variable cycle ramjet engines, that is an aspect that must be broken through! At the same time, what is even more perverted in the Soviet Union is that it uses liquid hydrogen as fuel, and this engine has better performance.

Unfortunately, this engine is not so easy to overcome technical difficulties.

What we just had a problem with is this variable-cycle ramjet engine. On our high-altitude test flight platform, this engine cannot be converted freely, and mistakes have occurred repeatedly. Sergey said.

In addition to undertaking the experiment of the complete machine, the Flight Test Institute also undertakes the flight test task of the engine. On the high-altitude test flight platform, the engine fails constantly.

Andre nodded. Of course, the development of this advanced engine cannot be smooth sailing, even for the Soviet Union with strong technical strength.

The sky of our Soviet Union is inseparable from our hard-working technicians. If we act according to scientific laws, we will be able to find defects and improve our engines. Andre encouraged.

Yes, I believe that our new reconnaissance aircraft can be successfully trial-produced. At the same time, we also have a modified bomber and an updated development plan. Sergey said: As long as this variable-cycle engine is successfully trial-produced, the next stage , Based on this aircraft, we will trial-produce a new aerospace aircraft, which can be used in outer space by carrying liquid oxygen.”

Aerospace engine... Well, this ideal is very beautiful. After all, Andre is not in charge of the equipment department, so Andre has no reason to block these plans.

Sudden,

Andre patted himself on the head: By the way, we are here to see the latest fighter jet from the Sukhoi Design Bureau.

After coming here, I was attracted by the supersonic airliner, and was fooled to come here again. Up to now, I haven't seen the target of this visit, the new generation fighter that has already started test flight!

This, of course, please come with me. Sergey said: Now, the American reconnaissance satellite just flew away from us, and we can conduct the next test flight.

…………

Just when the northern hemisphere is full of ice and snow, the southern hemisphere happens to be in a warm summer.

The northern hemisphere has more land, while the southern hemisphere has a lot of sea water. The land is mainly Africa and South America.

In Africa, the majority are black countries. It is poor, backward, and war-torn.

However, in such a world, there is a unique country, which is the only developed country in the third world in Africa!

This country is South Africa!

South Africa is located at the southernmost tip of the African continent. It is known as the country of the rainbow and has beautiful scenery. At the same time, the country’s economy is also quite developed. Relying on the production of gold and diamonds, South Africa is very rich. At the same time, South Africa’s scientific research capabilities are also incomparable developed.

In terms of weapons alone, South Africa has self-developed Horn tanks, Cheetah and Carver fighters, and even South Africa has a secret nuclear weapon development plan!

For South Africa, all these achievements can only be attributed to one thing, because South Africa is ruled by white people.

And in later generations, when the white regime disintegrated, South Africa's economy declined rapidly. When the black people gained the ruling power of the entire country and consumed all their wealth, they did not have any development. South Africa also developed from an advanced civilization. The modernized country in China has degenerated into a poor and backward country with deteriorating law and order, and the inertia of black people can be seen at a glance.

Now, the national power of South Africa is strong because of the rule of the white people. However, the Western world, which has always admired democracy and freedom, did not smile at the white government of South Africa. , expressing anger even more. At the same time, the Western world also imposed an embargo on South Africa, asking South Africa to compromise.

White people in South Africa are not white people in the Western world! On the contrary, there is still a deep contradiction between them!

The white people in South Africa belong to the Boers of Afrikaans descent. During the colonial period, the Boers in South Africa also succumbed to British rule, and the conflict between the two sides was very deep. The biggest contradiction is that during the Boer War in 1990, the British adopted a very cruel scorched-earth policy and detention in concentration camps against the Boers. More than 20,000 Boer women and children died in concentration camps due to hunger and disease.

It was these experiences that deepened the nationalist consciousness of the Boers themselves. In 1910, the South African Party won the general election, and after that, some laws related to racial discrimination and apartheid in the Transvaal Republic and Orange Free State were implemented throughout South Africa.

The basis of this law is to use the color of a person's skin to determine identity. South Africans are divided into whites, colored people (the descendants of intermarriage between Dutch whites and indigenous Nama people in the seventeenth century), Indians, Malays, and blacks.

Among them, blacks, who account for the majority of the population, are subject to great restrictions on freedom. More than 300 discriminatory laws stipulate where blacks can live, work, eat, travel, and whom they can marry, and stipulate that blacks over the age of 16 must carry ID cards, and cannot enter towns where whites live after dark, etc. wait.

This system is the apartheid system in South Africa. It is this system that has given the entire Western world an excuse to crusade against South Africa. At the same time, it is also this system that has allowed South Africa's economy to develop rapidly!

Black people are lazy, and the bosses who work on projects in Africa have a deep understanding of this. For example, when some bosses received a project to help African countries invest in infrastructure construction, they had clearly negotiated wages, but blacks still went on strike from time to time, demanding wage increases, otherwise they would not work.

Later, the contractors learned how to be good, and brought the workers directly from the country. As a result, the black people quit! No, leave the job opportunity to us, let us be employed!

Now, the South African government relies on the black labor force under control, the management skills of the white people, and the endless mineral deposits: gold, diamonds, platinum, uranium, manganese, and coal that accounts for 90% of all African reserves. Build it into the only developed country in Africa.

South Africa is more than self-sufficient in grain and exports surplus grain. Its gold mining volume accounts for three-quarters of the world's gold mining. It can manufacture various products from refrigerators to cars. It is economically self-sufficient enough to withstand sanctions from all over the world! This makes European countries in economic recession envy and hate.

Although the South African white regime adopts an apartheid policy towards blacks, in all fairness, the overall living conditions of South African blacks are the best in sub-Saharan Africa, with the highest level of education and the best medical care, but how can these blacks satisfy! They demand more power! They want to rule this country!

Therefore, the vigorous South African black movement is also in full swing. They only know that South Africa is now a developed country! This country should belong to them!

democracy freedom!

Unfortunately, the South African government will not destroy them. Successive leaders of the South African National Party, such as Daniel Malan, Johannes Stratton, Hendrick Verwoerd, and others, all believed that the abolition of the apartheid system would eventually lead to the destruction of South African whites. Therefore, on this key issue Up, South Africa will never back down!

Now, the ruler of South Africa is President Mares Verrien, who is also a tough leader. He and his assistant, Prime Minister Peter William Botha, are looking at the coming American envoy, Secretary of State George. (To be continued.)
