This weekend ( weather and schedule permitting ) I'll be launching a small AT I-to-G two stage to about 3,500 feet at the DARS.org Gunter TX launch. I built this smaller airframe to get experience with electronics and procedures for composite motor multi-stage while a much larger two-stage is being built.
I've configured my Raven4 to ignite the sustainer at:
A. booster burnout: no separation charge, it takes a sec or two for an AT motor to ignite
B. pressure decreasing: increasing altitude
C. altitude > 1,500 ft : OR simulates booster burnout at 1,800 ft
( A AND B AND C )
I ground tested this configuration with the Raven4 simulated flight feature and it passed.
for those that have done altimeter ignition of a sustainer motor, does this seem acceptable? I was thinking of adding a velocity parameter as well but want to keep complexity to a minimum.
