Electric-pump Rocket Engines: Comparative analysis of the electric-pump cycle using Rocket Cycle Analysis Tool (RoCAT)

The electric-pump cycle is a rocket engine configuration that uses an electric motor to power the pumps instead of a turbine. This offers several expected advantages such as simpler design, lower development costs, and easier restartability, but comes with reduced performance compared to conventional cycles. Previous research has primarily...

Transient Thermal Modelling of Cooling Methods in Green Bi-Propellant Thrusters for CubeSat Applications: A numerical and experimental comparison of regenerative cooling and radiation cooling in a CubeSat scale propulsion system

The Dutch/New Zealand based aerospace company Dawn aerospace has developed a 0.5N green bi-propellant propulsion system for use in CubeSat applications called the PM200. This thruster uses gaseous nitrous oxide and propylene as propellants. Currently, the burn time of this thruster is limited to 10 seconds after which cool down of the thruster...
