Good point. If we can assume the ambient temperature is above freezing - and for POGO, I think we can - than all we're talking about is cold peroxide's lag time. And I think Doug's right: if we put peroxide into a hot engine, I don't care how cold it is, it isn't going to have any lag time. >What's wrong with >simply giving each engine a few 50 ms pulses ten or twenty seconds >before liftoff? Armadillo did that with Spider. I don't recall if it was a warmup pulse, or just to verify the engines worked, but it's a good idea. -R -- "...And the last thing I remember is asking, 'What could go wrong?'" _______________________________________________ ERPS-list mailing list [EMAIL PROTECTED] http://lists.erps.org/mailman/listinfo/erps-list
