Why is kerosene used as rocket fuel?

SpaceX uses Kerosene in Falcon Rockets because up until 2007; there were no Methane engines. And Kerosene is cheaper, denser, stable at room temperature. It also has a higher energy density and presents a lower explosion hazard than LH2, and Kerosene rocket engines produce more thrust per dollar.

Why does SpaceX use kerosene instead of hydrogen?

For example, SpaceX Falcon 9 rocket relies on a combination of liquid oxygen and rocket-grade kerosene propellant, which has less mass than conventional rocket fuel. This lets them pack more fuel into their rockets, and to be able to place larger payloads into orbit.

Is kerosene a good rocket fuel?

RP-1 (alternatively, Rocket Propellant-1 or Refined Petroleum-1) is a highly refined form of kerosene outwardly similar to jet fuel, used as rocket fuel. RP-1 provides a lower specific impulse than liquid hydrogen (LH2), but is cheaper, is stable at room temperature, and presents a lower explosion hazard.

What fuel does SpaceX use in its rockets?

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.

Does SpaceX use solid rocket fuel?

While powerful, solid motors can’t be turned off once ignited. SpaceX’s Falcon 9 uses only liquid propellants, rocket-grade kerosene and liquid oxygen, and the result, the astronauts said, was a relatively fluid flight. “It was a very smooth ride. You could see it on the webcast,” Musk said after the launch.

Why is hydrogen such a good rocket fuel?

Hydrogen also provides low-density liquid fuel for navigation thrusters in orbit. The main engine of the space shuttle used liquid hydrogen fuel. Note how the hydrogen flames are almost invisible compared to the bright burn of the two solid rocket boosters on either side.

Does SpaceX use hydrazine?

During a test firing of the Crew Dragon’s abort thrusters, an explosion destroyed the SpaceX capsule and sent plumes of toxic chemicals including nitrogen tetroxide and hydrazine into the atmosphere. Hydrazine is a highly toxic propellant used in over 85\% of spacecraft for propulsion.

Which fuel is used in rocket fuel?

The petroleum used as rocket fuel is a type of highly refined kerosene. Cryogenic propellants are liquefied gases stored at very low temperatures, most frequently liquid hydrogen (LH2) as the fuel and liquid oxygen (LO2 or LOX) as the oxidizer.

What is the most common rocket fuel?

The most common fuel in solid fuel rockets is aluminum. In order to make the aluminum burn, these solid fuel rockets use ammonium perchlorate as the oxidizer, or to make the aluminum burn. In order to work together, the aluminum and the ammonium perchlorate are held together by another compound called a binder.

What is the solid fuel used in rockets?

The solid fuel is actually powdered aluminum — a form similar to the foil wraps in your kitchen — mixed with oxygen provided by a chemical called ammonium perchlorate.

Why are SpaceX rockets different?

1 is a 60 percent heavier rocket with 60 percent more thrust than the v1. 0 version of the Falcon 9. It includes realigned first-stage engines and 60 percent longer fuel tanks, making it more susceptible to bending during flight. The engines themselves have been upgraded to the more powerful Merlin 1D.

Why did SpaceX choose rocket grade kerosene for their Falcon rockets?

RP-1 is liquid at room temperature, easy to handle, is not toxic, easily transportable, has no leakage issue similar to Liquid Hydrogen, and Kerosene rocket engines produce much more thrust per dollar. Because of all these reasons, SpaceX chose rocket grade Kerosene for their Falcon rockets.

Is kerosene a good fuel for a rocket?

Kerosene is a good rocket fuel and on efficiency scale it probably lies next to only cryogenic rocket fuels. It is in liquid from at room temperature and easy to handle. Its leakage may cause problems but not severe as other liquid fuel does. Easy to transport, fueling and refueling of this, is much easier.

Why does SpaceX use kerosene to clean their Merlin engines?

Kerosene produces soot, coking, and polymerization inside the Merlin engine. As a result, after each rocket launch, SpaceX needs to clean its rocket engine thoroughly. This process is costly and prevents SpaceX from reusing their rocket in rapid succession.

What fuel does the SpaceX Falcon 9 use?

According to SpaceX’s website, the Falcon 9 uses kerosene as fuel. According to Wikipedia, diesel fuel beats kerosene in energy density in terms mass by 2.8 MJ/Kg and in volume by 5.6MJ/L, so why would they use kerosene instead?
