brenschluss \bren"schluss\, n. [German: end of burning.]
   (Rocketry)
   the time at which the engines of a rocket stop firing; the
   termination of the firing of the rocket engines, whether due
   to intentional shutdown of the engines or exhaustion of the
   fuel. This term was used mostly in the early days of rocketry
   when only one firing sequence occurred for rockets, which
   were used as ballistic missiles or for experiments in
   rocketry or atmospheric science.
