Another important regression parameter of the fuel is the IR absorbance of the fuel. When I was flying nitrous hybrids, the regression rate of black nylon was twice as fast as white nylon.
Keith PS Monroe, would you please contact me off list. At 10:02 PM 9/14/2014, you wrote:
How efficient is that control on most hybrids? I understand regression rate working in favor of the process. I do admit I have not run any calculations for regression vs oxidizer flow. Is it close enough to make that much up? If so it might rejuvenate some interest in hybrids for me. I'll have to look into it I guess I may have overlooked something there. My thinking was it wasn't enough.
