As I understand it, the oxygen in the air will liquidise, but not the nitrogen. What comes out the back is a kind of gassy slush. Jet exhaust would have high carbon dioxide and water content and that would solidify into both ordinary and "dry" ice well above these temperatures. Without knowing the detailed test regime, it probably needs a heat exchanger to keep combustion gases out of the precooler. Either that, or use an incandescent electric heater.TomS said:Not quite that cold -- it's about 40C above the liquefaction point. But yeah, it's pretty heroic. Keeping it from icing up seems like the worst part. Ice blocking channel in the precooler could cause serious problems, so they have to dry the air as well as chill it.sferrin said:Imagine the cooler required to take the exhaust from say, an F414 in afterburner, and turn it into liquid.
My main concern with bean-burritos, as suggested above, is that the very thin tubes of the precooler might curl up in disgust.
