Rocket propellant 's introduction

Today, we're going to talk about liquid rocket propellant!

Liquid oxygen/gasoline ---- the fuel of the first liquid rocket enginetris base distributors- YuanfarChemicalsOn March 16, 1926, Goddard successfully launched the first liquid-fueled rocket in history from Auburn, Massachusetts. The rocket uses liquid oxygen/gasoline as the propellant. The total length of the rocket is about 3 meters, and the engine length is 0.6 meters. Under the rocket, two tandem propellant tanks are connected. On March 16, Goddard, his wife and two assistants launched the world's first liquid rocket at Ward Farm. It flew only 12.5 meters high, 56.4 meters long and lasted 2.5 seconds, but it was the first liquid rocket ever launched. After the success of this test, Goddard improved the structure of the rocket by placing the engine at the tail of the rocket and taking measures to keep the rocket flying steadily.

 At the same time, he made further improvements to the engine's combustion chamber to provide maximum combustion efficiency. On July 29, 1929, Goddard's new 3.36m-long rocket was tested. It has a barometer, a thermometer and a camera on its head, and the camera is pointed at both instruments. When the maximum altitude is reached, the parachute's ejection switch simultaneously opens the camera shutter, thus recording the temperature and pressure of the atmosphere at the maximum altitude. The test rocket flew at an altitude of 32 meters and flew 53 meters horizontally, with parachutes ensuring that instruments were not damaged on landing. This rocket can be called "the first sounding rocket".
