Project
Sugar / Kno3 compacted powder engine

Construction

• These engines were my first attempt using sugar / Kno3 as a propellant. The engine casings were made out of cardboard tubing. The nozzle which was only a choke was made out of Pourstone as well as the end cap. The fuel was compacted in the engine casing in a powder form.

Pros

• Served as a learning experience for later engines.

Cons

• Cardboard tubing was not suitable for an engine casing.
• Powdered fuel has very unstable burn characteristics.
• End cap was not strong enough.
• A choke for the nozzle is inefficient.
