Heh... Looks like Mayo-chan's gonna be getting some British cousins. ![Smile Smile](http://www.accessdenied-rms.net/forums/images/smilies/smile.png)
Also, I find this engine of theirs to be rather fascinating - a hybrid of gas-turbine and rockets? Well played. I'm mostly curious about this pre-cooler setup how how they prevent a frost buildup inside the heat exchangers. Is it truly necessary to achieve temperatures as low as -130 degrees Celsius? Would 5 degrees Celsius not be sufficient?
