Can methane be used as a rocket fuel?

Liquid methane has been considered an attractive rocket propellant for several decades. The combustion process was shown to be stable in all tests and the operating transition from poor quality methane (two-phase fluid) at startup to liquid-liquid, sub-cooled, steady state operation was demonstrated.

Why are cryogenic fuels used in rockets?

Cryogenic fuels are fuels that require storage at extremely low temperatures in order to maintain them in a liquid state. Some rocket engines use regenerative cooling, the practice of circulating their cryogenic fuel around the nozzles before the fuel is pumped into the combustion chamber and ignited. …

Why next generation rockets are using methane?

Those efficiency savings mean significant cost savings, making space travel far cheaper. With a higher specific impulse, the quantity of methane required for lift off is less, meaning smaller fuel tanks. There is also easier storage of the fuel before launch, and simpler and lighter fuel pumps on the rocket itself.

Which compound is used as rocket fuel?

Hydrazine (H2N–NH2) is a high volumetric energy density liquid fuel (at room temperature and atmospheric pressure) that contains 12.6\% by mass hydrogen; it is also used as rocket fuel.

What propellant does SpaceX use?

SpaceX’s next-generation Raptor engine, which will power the company’s huge new Starship deep-space transportation system, employs supercooled liquid methane and LOX as propellants. The company’s previous engines, Merlin and Kestrel, have also used LOX, though with refined kerosene rather than methane.

Why is methane a molecular compound?

Methane, CH4, is a covalent compound with exactly 5 atoms that are linked by covalent bonds. There are four bonds from a central carbon (C) linking or bonding it to four hydrogen atoms (H). The methane molecule is this group of 5 atoms connected as such.
