Hi,
I'm actually having a very similar problem with the TORY Nuclear Ramjet Engine: I'm unable to get it working, it always states: Flame out! and Air-combustion failed. On top of this, I can't change the fuel/propellant that is used, neither in VAB/SPH nor on the runway/launchpad. Also there is no difference between no relative speed and speeds exceeding 20m/s. I tried it in sandbox-mode only with a MK1 pod an 2 Radiator Panles (Large) and it worked just fine on atmospher, hydrogen and liquid fuel as propellant. Why not in career-mode? What do I miss?
Here is also a list of all mods installed/managed with ckan:

I just unlocked the Nuclear Propulsion after both requirements (Heavier Rocketry and Advanced Fuelsystems) were met.
Maybe someone can help with that.
