The site is dedicated to his pursuit of liquid fueled rocket engine building. It’s a great project log and he has finally come to the point where he will be testing his first flight vehicle soon.

Rotating detonation rocket engines are an entirely different beast in that they generate thrust through detonation ... It solves fluid dynamics equations called Navier-Stokes equations, which ...

Chemical rocket engines provide huge thrust but are thirsty when it comes to fuel. Ion engines won’t get you out of Earth’s gravity well, nor do they work in the atmosphere, but become useful ...
