More power to you indeed . . .

Many Bloodhound SSC links from there to explore.

Bigger really is better.

18 inch diameter HTP-Hybrid combustion chamber and nozzle.
This is the most efficient format hybrid on Earth now.

Here is the HTP feed tank and pressurization system. The next step is pump
fed so the efficiency, pressure, and feed rate can be greatly increased,
while also reducing combustion instability and chugging associated with
self-pressurized hybrids! In addition to being very low pollution, the system
is capable of operating in monopropellant mode with ONLY water and oxygen
as effluent when the solid fuel is expended, for exoatmospheric operations.
From the very beginning this system was designed to be throttleable and serviceable.
It's time to make a system that will cause people to move beyond the speed of expectation.

Please sit down, turn DOWN the volume
and see something rare and cool.

Let's roll.

Just increasing operating pressure a bit improves efficiency enough
to form complete shock diamonds. This without even an optimum nozzle
throat diameter or expansion ratio settings. It keeps getting better!
All of our tests are done with flight weight hardware to keep it real.
