Booster
2 Blue Ravens
 
Nosecone

1 Featherweight GPS 
10-18-2025 SCORE Pueblo, CO

Main and Drogue deployed
Center coupler came loose at center and dropped to the ground.  Nosecone came down in parking lot under parachute and booster came down under drogue in a field close by. 
Data
Altitude GPS 9,903 ft.
Altitude altimeter 9,915 ft.
Inertial navigation max altitude was 9,793 ft.
Max vertical velocity GPS    1077 ft/sec or 734 mph
Max velocity (altimeter)    1257.80 ft/sec  or 858 mph  (>Mach 1)
Probable cause of flight failure:  It was determined that the center bolt spun itself loose causing a loss of the center section and each end of the rocket landed under the respective chute.
 
Flight 10-19-2025  Pueblo, CO
Drogue deployed and Main did not.  The main parachute altimeters were Blue Jay+ and I determined it was their failure to deploy that was the cause of the crash.  They were on at the launch pad with the correct settings.  Batteries were attached when I took the rocket apart after landing. 
Rocket came down about 2 miles away in a field.  It was retrieved with the help of the landowner.  Fin fillets were cracked on 2 fins but repairable.  The nosecone avbay (a 3d printed part) was cracked beyond repair. 
Because I wanted to swap out the Blue jays with Blue Ravens I needed to design a larger avbay.
Data
Altitude (altimeter)  10,806 ft
Inertial navigation max altitude was 11,445 ft.
Max vertical velocity GPS    1164.04 ft/sec  or 797 mph  (>Mach 1)
Max velocity (altimeter)    1033 ft/sec  or 704 mph
 
The Blue Jay+ data file (for the Main) called itself a Blue Raven.  It had Main as the deploy charge and battery at 4.2V.  Nothing fired.  So it had the right settings and enough power but just didn’t fire.  It recorded a start time as 35.12 and landing time as 37:55.9 so it was running the entire flight.  Upone inspection all wires were connected and tight.
 
Probable Cause of flight failure:  Failure of Blue ravens to fire a charge.

First attempt March 2025 premature deployment at pad.
Due to either memory from previous sim testing triggered a simulation or unit went on while travelling to pad and when placed upright computer thought it was a launch.  It was at the end of the day so no time for re-launch.o 1391 ft No electronics Motor ejection with parachute
