Question

Can Liquefied Petroleum Gas can be used as Rocket engine Fuel?

Answer 1

Rockets have cryogenic engines that do not work on these fuels… as the rockets have to travel in subzero temperatures far below… -100deg C… where normal fuel will freeze…

Cryogenic rocket fuels are trade secrets of the launching organisations and their countries…

Answer 2

Any combustible material can be used, even paper in a hybrid rocket motor. Spaceship One used rubber and nitrous oxide. This paper talks about propane as a propellant.

Apparently, a good fuel needs to also be a good coolant for the rocket nozzle.

Answer 3

Why would you want to?

The more weight, the more energy you will luse to lift it.  For any rocket you want the highest energy in the least mass.  You want the fuel that gives the "most bang for the buck (or pound)".

Answer 4

No, I don't think so.

LPG is mostly used domestic purposes.

And for a rocket fuel, i think more purified and powerful fuel is needed

Answer 5

No it does not have the kick of liquid hydrogen and liquid oxygen.
