    I recenly had this idea about rockets:

    A rocket creates its thrust when it ignites a substance in a chamber. The expanding of the hot gasses creates a pressure difference with the exterior, and the hot gas leaves the chamber at super high speed, creating a motion into the opposite direction.

    I then looked at chemical experiments where small granules of material, such as raw styrene beads, increase their size 100 times or more when heated.

    My idea is to inject small granules of an expanding material into the stream of hot gas, which would in turn make it expand tremendously. The stream of hot gas would then hit these expanded particles, and create more thrust.

    Does this even make sense ?

    Well the the pressure (caused by its expansion) and thus the thrust it creates is far more less than the thrust the same mass of fuel can.


    All that is necessary for the triumph of evil is for good men to do nothing.

    This alread exists, this is called solid rocked fuel. (just a little different)

    Now there are nuclear rocket engines (superheating liquid hydrogen to lift up)
    Growing up, i marveled at star-trek's science, and ignored the perfect society. Now, i try to ignore their science, and marvel at the society.

    Imagine, being able to create matter out of thin air, and not coming up with using drones for boarding hostile ships. Or using drones to defend your own ship. Heck, using drones to block energy attacks, counterattack or for surveillance. Unless, of course, they are nano-machines in your blood, which is a billion times more complex..

    ohhh, I didn't know that was solid rocket fuel... thanks
    -everyone
