Asteris 2 Program
In the pursuit to develop a larger liquid rocket engine as a successor to Asteris 1A, I began Asteris 1A SN2, which would be an entirely 3D printed chamber and injector out of Inconel 718. Slightly larger than Asteris 1A SN1, it's intended to produce 5.3kN or 1200 pound-force. It seems like a significant jump. However, Asteris 1A SN1 was supposed to have 300 pound-force of thrust, but valve and fuel pressure issues led to a substantial performance loss.
Ultimately the program for this engine would end up developing and testing a torch ignition system that was going to be used in this engine which is on another page.

A new and improved engine control computer was developed for this and future engines, which collects and transmits data along with controlling valve timings, ignition, and shut down of Asteris and other engines.
