Rocket motors are improving all the time. Nammo’s Hybrid Rocket technology, which was tested a few months back, is based on a rocket propellant combination of hydrogen peroxide as the oxidizer and synthetic rubber as the fuel. These hybrid rockets are safe, controllable, and a greener alternative to existing solutions.
The above video shows Nammo’s 1,000mph Hybrid Rocket in action. The firing lasted for 16 seconds producing a max thrust of 30 kN. Here is how the test went:
The engine started instantly after ignition and the firing was terminated in a controlled manner by closing the main oxidizer valve. Normally a full burn would have lasted 25 seconds, but on this occasion the test was terminated after 10 seconds for a full inspection. Full integrity of the motor was conserved, meaning that the engine could have been started again to burn for the remaining 15 seconds, if so desired.
BLOODHOUND, Nammo’s partner, will be using the same motor to power the BLOODHOUND Supersonic Car to reach a land speed record of 1000 mph next year.
