Alright heres my questions/idea.
Im not rocket scientist so im not quite sure what would work..or what is even sensible to try.
But I've wondered if there is a possible way to increase the effecieny of a solid propellant engine.
Obvioulsy the first thing would be to use the lightest/strongest materials and then cram it with a **BIG** engine. But there has to be a better way....
like putting some type of nozzle on the butt end near the nozzle(s) of the engine(s) to "pressurize" the gases.
Kind of like those Jet nozzles for your garden hose works. The same amount of volume of "stuff" (i.e. water/air) only being pushed through a smaller outlet.
Is there some type of material that would be able to withstand the pressure and heat?
or make some type of verticle "catapult" that pushes the rocket off the pad so that so much of the burn time isn't wasted while trying to lift.
Im pretty sure this is an already thought of and used idea...referred to as a piston?
im sure there are other options.
These may not be the most intelligent things you have ever heard but this is part of one of my soon, very soon upcoming rocs to push the super sonic or even sound barrier with different size of engine.
In a nut shell im trying to push the super barrier with the smallest engine possible...like an I size.
