3D printing rocket engine Low-poly 3D model

This is a Lox/Ch4 engine. Which means this engine is Feature of this specific engine:This engine has a ignition top.original industrial design file providednurbs faces are in maya files and iges files.only three partscould be 3D printed and put into practical use.the parameters are regulated and you can use standard parts.

How to use:Brazing between parts are very important before any testing or other usage.this engine should be tested first.Input ratio is 3.391 of lox and methaneMethane input holes at the bottom and there are three holesFirst heating the ignition head to the ignition temperaturethen slowly feeding with methane and oxygen. when found ignited, increase the amount till its working flow.then cut off ignition head heating.you should give all the fuel input holes same amout of ch4 and all the oxidizer holes same amount of oxygen.methane input should be liquid and you shoud use electric motor to feed liqued methanethe working temperature is 3600k and working pressure is 6Mpa
