Linear AeroSpike motor ( ~ 1MLBS thrust) with exhaust controlling flap (to adjust the ramp profile for altitude and chamber pressure). The motor uses gases O2 and liquid RP1. Exhaust cowl range is +15/-30 degrees. The motor is 6M wide 1M thick and almost 4M long.The side ramp units is for yaw control by using the APU's exhaust (with afterburner if needed).The forth screen shot is the per-mix (where fuel and O2 are first mix) which is a 3D printed unit. There is 198 of these premix units per engine.I used AeroSpike [http://www.aerorocket.com/MOC/MOC.html] to design the ramp.
