World’s first liquid hydrogen-powered plane unveiled
2023年9月8日
South China Morning Post
SOLVED: A cryogenic liquid propellant rocket using liquid hydrogen for fuel and liquid oxygen for oxidizer works on a gas generator cycle. The overall mixture ratio of the rocket is 4.0 while the mixture ratio in the gas generator is 0.6. The temperature of the hot gases in the gas generator (corresponding to the mixture ratio of 0.6) is 700 K. The pressure ratio across the turbine is 3. Find the fraction of the propellants required to be supplied to the gas generator and the mixture ratio in th

Do you know how rockets are launched? 🚀 Europe’s new launcher, Ariane 6 uses liquid oxygen and hydrogen as fuel to lift it off the ground and into space. This fuel is chilled to -150°C which allows more propellant to be loaded into the rocket with more fuel from the engine. But Ariane would not get far without the boosters that provide the most thrust by far. In order to control the direction of Ariane 6 after launch, the nozzles on the boosters and main stage can swivel to keep it on course. T
