What is the most effective kind of rocket fuel?

In combination with an oxidizer such as liquid oxygen, liquid hydrogen yields the highest specific impulse, or efficiency in relation to the amount of propellant consumed, of any known rocket propellant.

What is the biggest advantage to liquid fuel rockets?

Major advantages of liquid propellant rockets are that they generally have higher specific impulses than solids, the thrust can be throttled, the system can be restarted as often as designed, and the flow of propellants can be monitored and regulated to precisely control the magnitude of the thrust.

What are the advantages of solid fuel rockets?

The advantages of solid rocket propellants include: (i) simplicity, which is important for maintenance costs and savings in high production rate systems; (ii ) storage stability, with service lifetimes that can be as long as 30 years; (iii) resistance to unintended detonation; (iv) reliability, related to their …

What are the advantages and disadvantages of solid and liquid rocket propellants?

Relative to liquid fuel rockets, solid fuel rockets have lower specific impulse. performance is less than for liquid stages because of the solids’ lower exhaust velocities. and very high strength-to-weight ratio filament-wound motor casings. A drawback to solid rockets is that they cannot be throttled in real time.

What is the difference between a liquid rocket and a solid rocket?

Liquid-fuel rockets consist of a fuel and oxygen (or other oxidizer) in liquid state. They are combined in a combustion chamber and ignited. Solid-fuel rockets consist of a fuel and oxidizer that are pre-mixed in a solid form. Once the solid fuel is ignited, the resulting thrust cannot be regulated or turned off.

What rocket fuel does NASA use?

hydrogen gas
NASA’s hydrogen and fuel cell technologies are used for many purposes. NASA has relied upon hydrogen gas as rocket fuel to deliver crew and cargo to space. With the recent focus on human missions to the moon and eventually Mars, hydrogen will continue to be innovatively stored, measured, processed and employed.

What is a disadvantage of solid fuel rockets?

A drawback to solid rockets is that they cannot be throttled in real time, although a programmed thrust schedule can be created by adjusting the interior propellant geometry. Solid rockets can be vented to extinguish combustion or reverse thrust as a means of controlling range or accommodating warhead separation.

What are the disadvantages of liquid rocket fuel?

The biggest disadvantage of liquid fuels is that the need for pumps, piping and separate storage for the fuel and oxidant means that extra mass has to be carried by the launch vehicle. Many launch vehicles get around the problems by using a combination of different rocket motors.

Why are liquid fuel better than solid fuel?

Liquid fuels generally provide more energy than solid fuels and are easier to control. Liquid fuel engines can be throttled up and down during a flight. Solid fuels are easier to handle. They do not give off toxic vapors or require extreme cooling during storage and pre-launch operations.

What is the most powerful type of engine and is powered by liquid or solid fuel?

Answer: Engine of Bikes is the most powerful type of engine and is powered by liquid or solid fuel.

Why is liquid oxygen used in rockets?

If there is no oxygen in space, how do rockets ignite their engines? Rockets carry an oxidizer, often in the form of liquid oxygen, to burn their engine fuel.
