posigrade rocket การใช้

• The Redstone coasted for 10 seconds after its engine cut off; then a sharp report signaled that the posigrade rockets were popping the spacecraft loose from the booster.
• Before the Mercury 4 flight, Lewis Research Center and Space Task Group engineers had determined that firing the posigrade rockets into the booster-spacecraft adapter, rather than in the open, developed 78 % greater thrust.
• This happened after 5 minutes and 10 seconds in a direction pointing east, whereby the spacecraft would gain speed from the rotation of the Earth . } } Here the spacecraft fired the three posigrade rockets for a second to separate it from the launch vehicle . | group = n } } Just before orbital insertion and sustainer engine cutoff, g-loads peaked at 8 g ( 6 g for a suborbital flight ).
