MonoProp Rocket Engine

The target of this project is to develop a 50kgf mono-propelant rocket engine.


Purpose and goals

The key elements are:

  • The decomposition chamber + catalyst
  • Constant pressure oxidizer tank
  • Test stand to characterize the parameters of the engine

The actual engine (decomposition chamber) was realized mostly from cooper , despite large weight the cooper has the advantage of very good heat dissipation. Secondly the material mechanical properties changes little at high temperatures as long as melting point is not reached.

The oxidizer tank was make out of AL6061. The pressurization is achieved using a CO2 cartridge and an electronic control system to monitor and keep the pressure at a constant value of 20Bar.
