Modern military drones/UAV have some IR shielding/diffusion.

  How about some examples? This thing was apparently pretty small. I'd like to see how they managed to pack in all these abilities in something just a couple feet across.

    Basic IR shielding is not actually that complicated, you just need an opening to mix cold air with the exhaust as seen on the new H-60 derivatives.

      Exhaust will always mix with ambient air. You make it sound trivial to develop a turbine engine that won't show up on a thermal camera. If have figured out how to make doing so simple I'm sure many militarys are willing to pay billions for your ideas.

        The goal is to make it show up less.
