Hi,thought id start this one,whilst doing the Sa1,This is the first launch.of a design change to the previous three,as the next step in the moon race?.
Basically the differences are,The main mission reason,was to test the procedure for an engine failure in flight,so an engine was programmed to shut down,100 secs into the flight.The solution was the rocket to mreroute fuel from the stalled engine to the others,and burn longer to compensate.This was a total sucess,as it was used later on in the apollo missions,a few times.notably Apollo 13.
Also this rocket,had a few additions...the dummy 2nd stage was identical to the proposed flight ones....including all vent ducts,fairings .dummy ullage rockets...dummy camera pods..and it also flew with an antenna design used on the later flights,[thats the square panels near the tank tops btw?]
The SA4 has the unfortunate record of the most launch holds of any mission...
anyway,its basically same build as the SA1,so if you dont want to follow it? Thanks for looking Don
HI,this is the start...
