This project is solving the 3D Printing Contest challenge.
Project RAMP seeks to start the process of making rocket engines affordable by designing, building, and testing a sub $200 dual use rocket propellant pump capable of delivering 1 kg of propellant per second at 10 MPa of pressure. The pump will use no moving parts apart from a vibrating membrane to avoid needing sliding or rotary seals, and will achieve compression using shockwaves driven by pulsed combustion. Project RAMP intends for the pump to be operated and repaired using tools available at local hardware and computer stores. The pump will deliver a specific power of 50 kilowatts per kg to make it suitable for incorporation into ground to orbit engines through the use of a positive feedback resonance circuit. Finally Project RAMP will increase the number of people with experience with the pump by making it compatible for turbocharging car engines.
