posigrade การใช้

• :* You have retrograde and posigrade reversed here.
• The first burn should be a posigrade to increase velocity, raise apoapsis and increase the period.
• So your altitude is the same at the point where you made the posigrade burn, and greater than before everywhere else.
• The mission was to conduct a suborbital test flight and reentry of the spacecraft . The capsule had live posigrade separation rockets, but dummy retrorockets.
• 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.
• An Apollo TEI burn lasted approximately 203.7 seconds, providing a posigrade velocity increase of 1, 076 m / s ( 3, 531 ft / s ).
• :Simple answer; turning the rocket motor on again will impart an acceleration-if you trust posigrade ( in the direction of flight ), your rocket will gain speed.
• 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.
• A posigrade burn will raise your orbital altitude, but one of the fundamentals of astrodynamics is that if you perform a transfer between any two orbits, the two orbits must coincide at the point where you made the transfer ( assume an implusive ( instant ) transfer ).
• 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 ).
