Sorry I wasn't more specific. I have setup a better test craft and was able to generate more thrust this time, problem solved The issue I was having is that the description mentions that it works best over mach2 but my most recent test craft didn't really generate any meaningful thrust until over mach3.5. But I guess that is going to vary with altitude and intake area too. My previous craft were having trouble using the engine at mach 2.2 @ 10km. Cheers anyway.

I can't get the ramjet to generate any significant thrust in 1.2.2 with Realism Overhaul

I'm trying to build a nuclear powered aircraft but when I set the thermal turbojet to use atmospheric mode I get almost no thrust (0-0.5KN). It's connected up to the reactor properly as other propellants work as expected, its just atmospheric mode that doesn't. Anyone know why? Thanks. Edit// Test craft to show what I mean: Atmo: Water:
