Keven met us at FAR and we tried a 90 second hover. We just did not have enough thrust to lift the vehicle with the fuel necessary for a 90 second flight. We had margin in the system design, but not enough.
We never did get the mixing to work well enough to get proper decomposition. This lowered ISP meant more fuel to carry, higher liftoff pressures and higher flow rates on the flow orfices, we had some margin in each area, but the low ISP and poor mixing ovewelmed the margin. We can fly for 60 seconds, maybe even 75, but not 90 seconds with 25Kg of payload. We will try again in 2009 if there are prizes remaining.
I assume that at least the 180 second the 2nd place prize will be unwon.
I’m going to take some time off and relax, I want to thank all the people that have wished us well and folowed our journey. I also want to wish the Armadillo and truezero teams good luck.
