N2 - In this paper a rocket engine thrust chamber is designed and simulated for additive manufacture in aluminium. The design process is guided by the development of a numerical model for heat transfer of a regenerative and film cooled nozzle wall. Results are presented for a LOX/ethanol fueled engine with a thrust of 2.7 kN and a chamber pressure of 1.62 MPa. With film cooling peak heat flux at the throat is expected to be 7 MW m−2, and the wall temperature 480 K. Test samples of additive manufactured material were machined, and tested at elevated temperature. Reduction in yield strength at the intended operating temperature was consistent with other published data. The engine development is part of a project by a student team, "ANU Rocketry" which aims to launch a liquid fueled rocket into space. This project is to demonstrate the feasibility of developing an additively-manufactured, and regeneratively-cooled engine for the vehicle.
