in 1919, goldard wrote a paper entitled "the method to reach the maximum height" based on his research achievements for many years, which expounded the basic mathematical principles of rocket motion. He calculated that the rocket must have a speed of 7.9 km / s to overcome the earth's gravity. He also proposed a possible plan to send the payload to the moon by rocket. He vividly described: "if we build a rocket weighing 598.2 kg, we can send 0.9 kg of magnesium to the moon. Ignite the magnesium on the surface of the moon, and the bright flash of magnesium will last for a few seconds, and you can see it with an astronomical telescope on earth He accurately calculated the amount of fuel needed to propel a pound of object to infinite height, that is, the amount of fuel needed for a spacecraft to enter space and the moon. This calculation result has made a great contribution to the theory of rocket technology< Since 1920, he began to study liquid rocket seriously. Liquid fuel consists of two parts: one is fuel, such as kerosene, alcohol and liquid hydrogen; The other part is combustion supporting agent, also known as oxidant. Oxidants usually use liquid oxygen, but even at 183 ℃, liquid oxygen will boil into gas, so it is difficult to treat. Godard devoted himself to this. He built a liquid rocket static test and launch base at ward farm outside Auburn, Massachusetts. While working at Clark University, he went to the farm on holiday to do liquid rocket test. From 1920 to 1923, he did a lot of experiments and experienced many failures. In November 1925, he finally built a small liquid fuel rocket engine with a weight of 5.5 kg, which worked successfully for 27 seconds
at 2:30 p.m. on March 16, 1926, a miracle was born on the ice covered ward farm. The world's first liquid rocket was erected on the launch pad. When Godard cautiously ignited the liquid rocket with kerosene and liquid oxygen as propellant, he was immediately inspired by the scene in front of him: the rocket "noisily" flew up 12 meters, then turned to the horizontal direction, flew 56 meters, and fell into a vegetable field. The whole flight time was 2.5 seconds, which was a short moment, It made him the founder of liquid rocket. Excited about the success of the experiment, Goddard yelled, "I've done a miracle<
Goddard's liquid rocket is 3.04 meters long, which is composed of a 0.6-meter-long liquid engine and two fuel tanks. The launching frame is only a simple iron frame. At that time, the U.S. military did not realize the significance of this research. Except for a small amount of investment in the early stage of the experiment, it did not give any funding later. In November 1929, he had the honor to meet US Air Force Colonel Charles Lindbergh. He was the first pilot in the world to fly over the Atlantic on a single plane. He was a very influential figure. Lin Bai praised Goddard's rocket research work and helped him apply for funding from the foundation of Guggenheim, a famous philanthropist. In the next ten years, the Foundation funded 148000 US dollars. With funds, Goddard built the rocket research institute and test ground in Roswell, New Mexico, in July 1930. Later, he quit his job as a professor at Clark University and devoted himself to developing rockets. On December 30, 1930, another new liquid rocket was born, with a launch altitude of 610 meters, a flight distance of 300 meters and a speed of 800 km / h. In 1931, he first launched a rocket using a program system similar to that of a modern rocket. In 1932, he used the gas rudder controlled by gyroscope to control the rocket flight for the first time. He installed a rudder in the center of the jet port of the rocket engine. When the rudder rotates, it can change the air flow direction, so as to control the rocket flight. The rocket he developed in 1935 can fly at supersonic speed with a maximum range of about 20 kilometers. His outstanding contributions directly inspired the German rocket pioneers in the 1930s and laid the foundation for the later V-2 rocket
by the end of 1941, the Pacific War broke out. In order to meet the needs of war, the United States government appointed Goddard as director of the Naval Aviation Research Bureau from 1942 to 1945 to study the jet propulsion and variable thrust liquid rockets for auxiliary military aircraft. However, his lung nole disease had entered the advanced stage. On August 10, 1945, Goddard died of illness. In his life, he has obtained 212 patents in rocket technology< Although Godard successfully developed the world's first liquid rocket in 1926, it did not attract the attention and support of the U.S. government. Therefore, after his death, the rocket technology of the U.S. still lags far behind that of Germany. It was not until 1961, when Soviet astronaut Gagarin went into the sky, that the United States published all the reports on Goddard's 30 years of liquid rocket work. Later, he was known as the "father of Rockets" of the United States. In memory of his achievements, a space flight center of NASA was named "Goddard Space Flight Center". In 1958, when the first satellite of the United States was lifted up by a carrier rocket, Lin Bai, a flying hero who was a friend of Godard, stood at the launch site and said with infinite emotion: "in 1929, Godard showed me a blueprint for the development of multi-stage rockets. Today, 30 years later, at Cape Canaveral Air Force base, I saw with my own eyes the moving scene of a huge multistage rocket rising into the air. I don't know whether he was dreaming then or I am dreaming now
happy base camp who is the undercover (4)
the program of happy base camp named the adapted game "who is the undercover", which is a very interesting and popular game of language expression ability, knowledge and imagination. It's the first choice of happy games when many people get together
players are divided into judges (questioners), undercover agents and others (collectively referred to as civilians). In the game, the appellation of "civilian" and "undercover" is just to distinguish two different game identities, and has no special meaning[ 2]
game overview editor
the party game "catch the ghost" is a very interesting and popular game to compare language expression ability, knowledge and imagination all over the country. It's the first choice of happy games when many people get together. At present, there are three versions of the game rules: Ghost 1.0, ghost 2.0 and ghost 3.0[ 1]
2 background editor of the game
this game has graally spread since 2010, and the original is unknown. The team began to study the game in July 2010, and constantly improved the rules of the game in the process of frequent testing, so as to make the winning rate of the game more reasonable and make the game more simple, rigorous and fun. The appellation of "human" and "ghost" in the game is just to distinguish two different game identities, and has no special meaning[ 1]
