University of Washington researchers have developed a mathematical model that describes how rotating detonation engines work.

But a new type of engine — called a rotating detonation engine — promises to make rockets not only more fuel-efficient but also more lightweight and less complicated to construct.

From the GeekDad mailbag, we’ve received the following request: My son and I have decided to build and fly our own model rocket. However, I am hopelessly mechanically and electronically dopey. I ...
