Transmigrated as the Crown Prince

That night, a hundred V-1 missiles were fired at London. More than fifty of them landed in London, and the rest fell and exploded due to malfunctions on the way.

Dr. Obert, who came to report, explained with a look of shame. "Sorry, Your Highness, this is the first batch of production, and its performance is not stable. But I can guarantee that the failure rate will be lower as time goes by."

"I'm very satisfied, Dr. Obert." Yannick smiled disapprovingly, because he knew that the German army in the original time and space launched 244 V-1 missiles towards London and 50 towards Southampton for the first time. Of these, 144 crossed the English Channel; 73 hit London.

After all, it was a hastily launched project, and they had been studying it for several years. More than fifty out of a hundred hit London, which was much stronger than the original time and space. "Last time you said that the V-2 rocket was reaching an altitude of 189 kilometers, so it could almost launch satellites into the sky."

The deployment orbit of the satellite needs to exceed an altitude of 120KM. If it does not reach an altitude of 120KM, the satellite will fall down.

As we all know, the earth has an atmosphere. 90% of the atmospheric mass is below 30Km, and it gradually becomes thinner above 30Km. As altitude increases, the air density drops sharply. At an altitude of 100km above the ground, the air density is one millionth of that at sea level; at an altitude of 120km, the air density is tens of millions of times that at sea level; Below an altitude of 120KM, the satellite will be affected by air resistance and cannot achieve a resistance-free flight environment, so it can only fall.

The United States launched a satellite in 1959, which was 112km from the lowest point on the earth. The satellite was launched successfully. It circled the earth once and then fell down.

Dr. Aubert looked troubled. "Your Highness, there are still some difficulties at present. The rocket still needs to increase its thrust." The last launch to an altitude of 189 kilometers was just a test, and there was nothing extra in the rocket except fuel. "We're trying a 'rocket train' approach."

As early as 1929, Russian scientist Tsiolkovsky first proposed the concept of "rocket train". At that time, he thought that the mass of a single-stage rocket was relatively small and it was difficult to achieve the speed required to enter space (cosmic speed) , so it is envisaged that multiple rockets are connected in series. When the propellant of the bottom stage is consumed, its shell will fall off on its own, thus increasing the mass ratio of the remaining rockets. By analogy, the last stage rocket can reach the required cosmic speed.

Of course, when Tsiolkovsky wrote this paper, liquid rockets had not yet appeared. The data he relied on were the parameters of gunpowder rockets. Therefore, the estimated number of rocket stages was much larger, so he called it a "rocket." train".

Yannick shook his head slightly. "Dr. Obert, it is not necessary to have a multi-stage rocket to send a satellite into the sky." Because the launch vehicle of the first artificial satellite launched by the Soviet Union was a single-stage rocket. It's just that four more rockets, also called boosters, are bundled around the middle core stage rocket.

The booster and the core-stage rocket are ignited together on the ground. After working for a certain period of time, they are shut down. After shutting down, they are separated from the core-stage rocket and thrown away. Because the booster was shut down halfway through the flight of the first-stage rocket, it can only be considered a half-stage rocket. The Soviets used this one-and-a-half-stage rocket to launch their first satellite, Sputnik 1, into an orbit at an altitude of 215km.

Seeing the structural diagram drawn by Yannick on the paper, Dr. Obert suddenly realized. "That's okay."

"But this is just a stop-gap measure. Multi-stage rockets are the right way to go."

Later single-stage rockets were favored by the aerospace sector due to their simplified structural design, reduced number of engines used, and reduced separation times, and were even developed into recyclable and reusable rockets.

But that was 70 years later. During this period, we still had to rely on multi-stage rockets.

While Yannick and Dr. Obert were happily discussing the future development of rockets, in the Prime Minister's Office on the other side of the strait, Churchill was yelling hysterically. "Revenge! Revenge!!"

The main reason for losing such a temper was that a V-1 missile accidentally hit Westminster Abbey last night, directly destroying half of the building and leaving the other half crumbling.

The construction of St. Minster Abbey began in 960 AD and was completed in 1065. It was established by King Edward of England in the 11th century, who was known as the "Faithful". Since its construction, the church has been the venue for the coronation ceremonies of British kings or queens and the wedding of royal members. Most of the British kings were buried here after their deaths. After the British bourgeois revolution, many famous people also occupied a place in the church after their death.

Such a building with a long history and full of humanistic significance was actually blown up. Churchill was filled with anger and fear. His revenge plan was very simple, which was to dispatch the air force to respond to the Germans with poison gas bombs.

Churchill was not opposed to gas warfare, and even favored chemical gases.

In the summer of 1919 in the original time and space, the British army fought with the Soviet Russian army. The British army used aircraft to drop poison gas on the Bolshevik area. Churchill also advocated the implementation of a chemical weapons program against northern India, but this plan was abandoned due to opposition. He asked very unhappy: "Why do we waste artillery shells when we have chemical weapons? You are really stupid!"

In 1950, Churchill felt the pressure from the Soviet Union to vigorously develop armaments. He believed that if the Soviets developed more advanced chemical weapons first, Britain would be passive, so his enthusiasm for chemical weapons was rekindled. Under his advocacy, South Kirkuk on the Cornish coast developed from a small testing site into a large-scale chemical weapons testing and production base. From 1954 to 1956, this production base produced about 20 tons of sarin gas, and developed and manufactured several new types of chemical weapons.

Until 1965, as the voice of opposition became stronger and stronger, the British trust and respect for the authorities were in crisis. The secret of Nanke Cook could no longer be kept and was exposed to the public, causing an uproar. The famous British magazine "Peace News" published an article about the Nankok gas leak accident in December of that year, satirizing the sanctimonious and ugly face of it.

After World War I, various countries ostensibly agreed not to use poison gas bombs. However, as a means of defense, even if they did not use it, they could not do without it, otherwise they would suffer a loss in a real war. Therefore, the United Kingdom stored a large number of poison gas bombs.

But when he informed the Air Force of this plan, he encountered firm opposition. The first is that it is now difficult for the British Air Force to break through the German air defenses and drop poison gas bombs on the German mainland. Second, the German chemical industry is also very developed, and poison gas is not difficult to make. Once needed, the pesticide factory can immediately become a poison gas bomb base.

Once the German army is attacked by poison gas, the Germans will definitely use the same method to fight back, as long as the warhead of this flying bomb (V-1 missile) is replaced with a poison gas bomb. What's more, no one can guarantee whether the Germans will have more lethal poison gas, and the consequences are not what Britain can afford.

Under the strong persuasion of the Air Force, Churchill reluctantly gave up the plan to use poison gas and could only wait for Spain's "secret".
