The liquid hydrogen in the first stage, the nitric acid ,alcohol with 100%, kerosene, dimethyl hydrazine, is used for the primary boost. And the liquid oxygen, tetraoxynitride is used for burning and chain-reaction and heating chemicals.
One kilogram of special material needs at least 50 kilograms of fuel .
There are two situations. First: If the rocket is a cargo, counting the aerodynamics and the cargo net weight. Then multiply 50 or 100 this is the requirement weight (kilogram) . Second: If it is a crew, calculate the weight of the astronaut and the apparatus and the command module. Then multiply 50 or 100. So this is the requirement weight of the crew.
The Space X’s engines are the highest-tech engines in the world, like the Merlin 1-D. Their efficient is fast and the booting power is high, or the highest.
Then, I have a hypothesis: What will happen if we only put the crew or the cargo on the second stage, and the first stage has only hydrogen, and the fuel mentioned before for landing procedures. And some hydrogen balloons are tied up an till it gets to the space the first stage separates, and cut off the balloons.
Although the speed is slow and it may fail, but it is worthy to try it.
Or we can just use a complex of flame ejectors can form some simple engines and I don’t think it will go faraway. One type of flame ejectors is used by gases and it is often used for SOS. And the other kind is for cooking. So I have another hypothesis again: With combining 5 gas flame ejectors in the first stage and one cooking flame ejector in the second stage with an electrical separator, aerodynamics, one satellite. And they are all in the scale of 1:11, including the fuel. The full scale rocket is Saturn V. Saturn V is approximately 3039 tonnes, by divided by 11, it’s approximately 272 tonnes. But I think I can decrease the weight from 272 to 10 tonnes, why? Because I don’t use liquid fuel, I use gas fuel.And the height is approximately 20 metres.And I think it is high efficient rocket.But it only needs 4 more available gas tubes per gas flame ejector and 5 available cooking flame ejector’s fuel tank. They are all connected and stacked together in order to make the ejection longer, to let the rocket to go in the space. And a camera to take a photo to remember this excellent moment(just kidding, I even didn’t try yet!).Or maybe I can let Bunsen Burner to replace the cooking flame ejectors. Because first: I don’t want my spaceship being cooked and the second thing is Bunsen Burner is stronger than cooking flame ejectors.
If there is enough Bunsen Burner , I will only fill a big oxygen tank to energies the Bunsen Burner, every Secondary School students know that.
So that’s why I can decrease the weight to 10 tonnes.
The atmosphere, the place where most satellites orbit. But it is the most dangerous place for spaceships. With the thick layer of air and the high velocity if the spaceship. It causes frictions, with these frictions, it produces the hot air approximately 1400 degree Celsius.
So if you spaceship doesn’t have a heat-proof layer, you will be burnt!(Just Kidding)
And that’s all. Thanks for reading!!! : )
