Therefore, people didn't pay attention to his scientific thought at that time.
It was not until 20 years later that some scientists in the United States and Europe began to develop Tsiolkov.
Rockets, space vehicles envisaged by the Foundation. Among them, Goddard of the United States contributed and was
People call it "the father of rockets".
Goddard188210/kloc-0 was born in Massachusetts, USA on October 5th. Still studying in middle school
At that time, he was fascinated by space flight. 19 1 1 year, Goddard received his doctorate, and at this time he
I am more interested in the study of rockets. 19 13 He pointed out through calculation that a 200-pound (about 90.
A rocket weighing 1 lb (about 450 grams) can push an object out of the atmosphere and enter.
Space. Soon, he obtained two patents: liquid and solid propellant for rockets; land
Multistage rocket in space. 19 19 in may, Goddard published a paper that shocked the scientific community.
The way to reach the height. The article points out that the rocket flies at an altitude of 650 kilometers.
The take-off mass also gives the flight speed required for the rocket to reach the moon.
1925 12, Goddard developed a 5.5 kg light liquid fuel rocket engine.
Motive. After the rocket ignited and burned, it rose from the bracket and tightened the rope that held it tightly. this
He was greatly encouraged by his second success.
1926 March 16, Goddard conducted a formal experiment: first, set up a metal frame.
A rocket launcher consisting of a shelf with rockets on it. The rocket is no more than 3 meters long.
Covered and uncovered, one for storing boxed gasoline and the other for containing liquid oxygen. exist
Ignition at 2: 30 pm, gasoline and liquid oxygen mixed combustion, spraying a rapid flame flow.
The rocket rose 12.5 meters, then turned left, flew forward 56 meters, and finally landed in the field.
The fuel burning time is 2.5 seconds.
This is the first liquid in the world.
