So the five hour turnaround would have been a three hour turnaround
had you been using a non-cryogenic oxidizer? :-)
What does your turnaround consist of? I was tweaking Aleta a little
bit about XCOR shooting for ERPS' 2:10 turnaround time for KISS II,
but all we have to do is:
1) Wait for rocket to land
2) Go get rocket
3) Safe pyro
4) Bring rocket back
5) Split modules
(Propulsion module track)
P6) Load rocket on launch rail
P7) Purge tank
P8) Take rocket off launch rail
P9) Mate propulsion module with recovery module
(Recovery module track)
R6) Download flight data
R7) Clean pyro area of residue
R8) Load new pyro
R9) Pack/load parachute, attach nosecone
R10) Mate with propulsion module
11) Load rocket on rail
12) Fuel rocket
13) Pressurize rocket
14) Arm pyro
15) Launch
Gosh, not as simple as I remembered, and that's with some
oversimplification. So what kinds of things do you have to do to turn
around EZ-Rocket?
