Dynamic pressure, engine burn, feathering
Any drastic configuration change like feathering is not to be expected until well after q_max and most likely after motor burn-out (except perhaps for considerations as mentioned in Case Oneīs post, not sure if such considerations apply in the SS2 flight profile).
Could anyone enlighten about dynamic pressure vs time/altitude for SS2?
The video footage of the third powered flight shows feathering action just after motor burn-out.
p.s. Just read DontHangUpsīs comment, it does seem there is multiple use of the feathering system, interesting.
