Self-Eating Engine Lowers Launch Cost

Self-Eating Engine Lowers Launch Cost
May-25-18
An innovative, self-eating rocket engine that uses its structure as fuel could lower the cost of placing small satellites in orbit.

In development by teams from the University of Glasgow and Oles Honchar Dnipro National University, the autophage engine would replace heavy propellant storage tanks with a solid fuel rod full of a powdered oxidizer. As the rod is forced into the engine, the fuel and oxidizer are turned into gases that can be combusted to provide thrust while also generating enough heat to continue the vaporization process.
