Going from a simple flat washer to a properly expanded divergent cone will
improve performance over 40%.

Does length of nozzle matter in
PVC motors? Like exhaust flame and smoke, overall motor
performance etc..In my all past motors, i have used
30mm of length of convergence side(washer to upper end of
nozzle) and convergence cone was 40° to 60° in between.
Divergence was same as suggested by Chuck Knight's PVC
motors.Here's is the last success but longer
burn of the motor.https://youtu.be/Ppq_LfDHDAo
