A test fire of our new GOX (Gaseous Oxygen) - Acrylic Hybrid Rocket Motor.

The excellent thing about this is that because the acrylic is transparent you can see the combustion reaction inside the rocket as it progresses.

The motor is a hybrid as it uses a solid fuel (the acrylic) and a gaseous oxidant (oxygen gas). It has some advantages over a solid propellant motor in that it can be turned on and off and thrust can be regulated to a certain extent by varying the oxygen inlet pressure. In this video we don't go above 40 psi inlet pressure but we will test it at higher pressures in the future.

We haven't measured the thrust yet but it doesn't appear to be much at all - certainly not enough to move it across the table but we clamp it down just to be safe.

What is Wonderstruck? We're a company committed to spreading the joy and wonder of science, engineering and maths. We like things that move fast, things that go bang and/or catch fire, we have a good sense of humour and our favourite chemicals include thermite and liquid nitrogen.
