What are the advantages of Xiang Yu s army? What are the shortcomings?

Advantage: Xiang Yu.

Raised troops in the Jiangdong area, leaving the Qin Dynasty.

Xianyang is relatively far away, and at the same time he owns the state of Chu.

With his unparalleled bravery, he also received the support of many rebel troops. He is the first military general in the ages, a king who fights head-on, and is very good to his subordinates.

Disadvantages: Xiang Yu doesn't understand the art of the emperor. What Xiang Yu is good at is to give full play to himself and take charge of the affairs of his abbot. Once anyone and everything is not managed by themselves, they will lose control. He doesn't know how to control people and how to balance for a king.

Xiang Yu does not pay attention to strategy or politics, and he can divide one side and become the hegemon by relying on his command ability alone.

Discharge cooling is another type of convection cooling. Unlike regenerative cooling, the coolant used for exhaust cooling absorbs heat to the thrust chamber and is discharged out of the combustion chamber instead of entering the combustion chamber to participate in combustion. Direct drain coolant reduces the thrust chamber specific impulse, so the coolant flow for drain cooling needs to be minimized while only using drain cooling at the outlet section of the nozzle that is relatively less heated.

There is also radiative cooling, in which the heat flow is transferred from the combustion products to the thrust chamber, and then the heat is radiated by the thrust chamber wall to the surrounding space. Radiative cooling is characterized by simplicity and small structural mass. It is mainly used in the extension section of large nozzles and the thrust chamber of small thrust engines using high-temperature resistant materials.

When cooling in the thrust chamber of the tissue, a relatively low temperature liquid or gas protective layer is established on the surface of the thrust chamber wall to reduce the heat flow to the thrust chamber wall, reduce the wall temperature, and achieve cooling. Internal cooling is mainly divided into three methods: internal cooling (shield cooling), membrane cooling and diaphoretic cooling of head tissues. After the internal cooling measures are adopted in the thrust chamber, the mixing ratio near the wall of the combustion chamber is different from the optimal mixing ratio in the central area (in most cases, the near-wall layer rich in fuel is used) due to the need to reduce the temperature of the protective layer, resulting in the uneven distribution of the mixing ratio along the cross-section of the combustion chamber, so that the combustion efficiency is reduced to a certain extent.

Membrane cooling is similar to shield cooling in that it cools the thrust chamber wall by establishing a uniform and stable coolant film or air film protective layer near the inner wall surface, except that the coolant used to establish the protective layer is not injected by the injector, but is supplied through a special cooling belt. The cooling band is generally arranged in a cross-section of the combustion chamber or the convergence section of the nozzle. There can be several cooling bands along the length of the combustion chamber.

In order to improve the stability of the membrane, the coolant often flows through the gaps or small holes in the cooling belts, and when sweating is used, the thrust chamber wall or part of the inner wall is made of porous material with a pore diameter of tens of microns. Porous materials are usually sintered with metal powders or pressed with metal mesh. In this case, the number of pores per unit area is increased by making the micropores in the material as evenly distributed as possible.

The liquid coolant penetrates into the inner wall, creating a protective film that reduces the density of the heat transferred to the wall. When the flow rate of liquid coolant used for sweat cooling is above a certain threshold, a liquid film is formed near the wall of the thrust chamber. When the coolant flow rate is below the critical flow, the inner wall temperature will be higher than the coolant boiling point at the current pressure, and some or all of the coolant will evaporate, forming an air film.

In addition to the above thermal protection, there are other thermal protection methods such as: ablation cooling, thermal insulation cooling, hot melt cooling and composite protection of chamber walls. 3. Thermal protection scheme of high enthalpy gas generator Based on the above methods and the actual situation, the thermal protection method of high enthalpy gas generator is obtained.

The combustion chamber of a high-enthalpy gas generator differs from that of a liquid rocket engine, eliminating the front thrust chamber part, making its structure simpler and more effective. Then, the thermal protection involved is the thermal protection part of the combustion chamber wall. As the fuel enters the combustion chamber, it quickly decomposes and releases large quantities.

Xiang Yu in the Battle of the Giant Deer.

The battle of Julu was a great uprising at the end of Qin, and Xiang Yu led tens of thousands of Chu troops with the famous Qin general Zhang Han.

A major decisive battle with the main force of 400,000 Qin troops led by Wang Lisuo in Julu (now part of Pingxiang County, Xingtai City).

Xiang Yu broke through the cauldron and took the lead in attacking the Qin army when the princes' armies were cowering, leading the princes' righteous army to finally annihilate the king's army, and forcing the other 200,000 Zhang Qin troops to surrender eight months later. From this feather, he established a leading position among the rebel armies. Qiao Sui coincidentally went through this battle, plus Liu Bang.

The army of the Western Road broke through Wuguan and Lantian, and the main force of the Qin Dynasty was lost, and it existed in name only.

The most fatal time was when Chen Ping threw a discordant plan into Xiang Jiajun, which not only delayed the opportunity to attack Xingyang, but also laid off the main generals and military divisions who followed Xiang Jiajun, and after that time, Xiang's army was already paralyzed.

Unpopular with the people, Bai pit killed 200,000 prisoners, no.

DU is good at using talents. zhi

The courage of the horseman, the personal heroism of the dao, is too self-sufficient.

Edition. I don't have the right to think and I don't want to take advice. Unlike Liu Bang, as long as he thinks this opinion is reasonable, he will adopt it.

For example: When worshipping Han Xin as a general, he adopted Xiao He's suggestion, put aside women, wine and meat, and respectfully worshiped Han Xin as a general. This is Liu Bang's advantage, and it is also Xiang Yu's shortcomings!

1. Lack of strategy and vision, and lack of politicians.

2. There are extremely serious flaws in Xiang Yu's personality.

3. There is more cruelty than benevolence; Lacks the temperament of a monarch who is obedient and magnanimous.

01 Xiang Yu's rule was unpopular with the people, which was the fundamental reason for his failure, he always relied on force to solve everything, and he also killed the surrendered Qin army, which was not supported by the common people. Secondly, Xiang Yu is very indecisive, although he is a tyrant through the ages, he is brave and unscrupulous, very arrogant, unsightly, very vain, and very brutal. Xiang Yu lacks the decision that an emperor should have, he should be killed, and he should be killed, and Liu Bang has become a dead soul under the knife because of his indecision, but Xiang Yu was doomed to defeat because of his indecision.

Xiang Yu was very indecisive in his life. Han Xin and Liu Bang said that although Xiang Yu was very brave, he was a woman's kindness. The Hongmen Banquet set up by Xiang Yu back then was intended to end Liu Bang, and at this time, he also had the ability to completely win Liu Bang, but Xiang Yu did not make a choice because of indecision.

At that time, his father Fan Zeng kept giving him a look, but he didn't listen, but he listened to Xiang Bo's words, and Liu Bang said a lot of good things, he thought that Liu Bang didn't have the ability to fight against him, so he let Liu Bang go and lost the opportunity to seize the world.

Although Xiang Yu is the first overlord of the ages, he is brave and strategic, he only knows how to solve everything by force, but he does not use his mind to think about things. Sometimes he listens very much to others, but other times, he always does what he thinks in his heart, so he sways from side to side. If he really had a plan, he would definitely kill Liu Bang at the Hongmen banquet, and would not choose to let go of his biggest opponent.

Xiang Yu is very arrogant and has no one in his eyes, he always feels that he is the overlord of the world, and no one in the world can confront him, and his arrogance has caused one of the reasons for his failure. And Xiang Yu is very obvious, in the battle of Pengcheng that year, he almost killed Liu Bang, because the sky blew a strong wind, and the flying sand and rocks fascinated Chu Jun's eyes, at that time he was saying, is it that God wants to help Liu Bang, not help me Xiang Yu?

Xiang Yu is a very vain person, and very brutal, he cares about his subordinates very much, but every time he attacks the city and captures the wall, he will always slaughter the city, making the local people miserable, and everyone is complaining.

Xiang Yu's rule was unpopular with the people, which was the fundamental reason for his failure, he always relied on force to solve everything, and he also killed the surrendered Qin army, which was not supported by the common people. His approach and his character eventually made him rebel against his relatives, not only did he not unify the world, but he finally ended up killing himself in Wujiang and lost his most beloved woman, this history was called "Farewell My Concubine" by later generations!

The Battle of Julu and the Battle of Pengcheng.

1. The Battle of the Giant Deer.

The Battle of Julu was a major decisive battle in Julu (now Pingxiang, Hebei) led by Xiang Yu to lead tens of thousands of Chu troops (the later princes also participated in the war) and the main force of the 400,000 Qin army led by the famous Qin generals Zhang Han and Wang Lisuo in Julu (now Pingxiang, Hebei) in the great uprising at the end of the Qin Dynasty.

Xiang Yu broke through the cauldron and took the lead in attacking the Qin army when the princes' armies were cowering, leading the princes' righteous army to finally annihilate the king's army, and forced the other 200,000 Zhang Qin troops to surrender eight months later.

From this feather, he established a leading position among the rebel armies. After this battle, the main force of the Qin Dynasty was completely lost, and it existed in name only.

2. The Battle of Pengcheng.

The Battle of Pengcheng took place in April of the second year of the Han Dynasty (205 BC) and was one of the major battles of the Chu-Han War. In the first battle of Pengcheng, Liu Bang suffered the biggest defeat since the beginning of the army.

Relying on Xiang Yu's resolute and resolute command, the Chu army defeated the 560,000 people of the Han army with 30,000 troops in half a day, annihilated Liu Bang's main force, and plunged Liu Bang into a crisis situation of "the old and weak in the pass", creating a model of a quick decisive battle in ancient wars, and a famous example in Chinese history of winning more with less.

Battle of the Great Deer! Xiang Yu's 50,000 Chu army vs. Zhang Han's Qin soldiers 400,000! Xiang Yu broke the cauldron and sank the boat, that is, after crossing the river, he sank the boat, smashed the cooking pot, and stipulated that each person in the whole army could only bring three days of dry food, showing the determination to fight to the death in three days without success!

Later, the whole army fought bravely to the death, and the morale was greatly boosted! Defeated 200,000 enemy troops! In the end, Zhang Han, the general of the late Qin Dynasty, also had no choice but to surrender.

Battle of Pengcheng: Xiang Yu's 30,000 Chu army vs. Liu Bang's allied army 560,000! At that time, Liu Bang united the princes of all parties to attack Chu under the pretext of King Chu Huai's killing by Xiang Yu.

But after Liu Bang captured Pengcheng, he only cared about drinking and having fun, and Xiang Yu only brought 30,000 people, so he looked down on Xiang Yu even more. Xiang Yu used the tactic of luring the enemy deep into the army and then launched a surprise attack, killing more than 100,000 coalition troops, and another 100,000 jumped to their deaths when they fled. Xiang Yu also used the method of dividing troops and assaulting to make the favored combined army unable to care for each other when there were many people and chaos, and they were defeated!

Liu Bang also fled in the chaos.

Most of Xiang Yu's battles are more with less, and his main means is to directly smash the enemy's army (the opponent's battlefield headquarters), but the main is the battle of Yongqiu, the battle of Julu, and the battle of Qixia, the three famous battles, all of which are more than a few, the first two are victorious, and the latter is defeated.

The Battle of Julu, the Battle of Qixia, the Battle of Xingyang, and the Battle of Huaiyang. Battle of Sanqin.

Xiang Yu is very indecisive, although he is a tyrant through the ages, but he is brave and unscrupulous, very arrogant, no one in his eyes, very strong vanity, and very brutal.

Xiang Yu won in some battles, relying entirely on personal courage, not using people, and even more despising people from poor backgrounds.

Xiang Yu's rewards and punishments are not clear.

Xiang Yu did not know how to establish and consolidate the rear, blindly killing, and was strategically in a passive position.

Xiang Yu is a very legendary figure in history, the so-called strength to pull out the mountain and cover the world, so his force value is very high, and his character is also a fierce attack type, this kind of character is full of pioneering and pioneering ability, but obviously if there is no very strong assistance, it is difficult to achieve the hegemony of the emperor.
