Back in 2008 or 2009, the R.S. Barker "Silverleaf Design" drawing of the DELTA III was being discussed on another forum group. That drawing incorrectly shows the DELTA III as having GEM-40 boosters.
The creator of that drawing was made aware of the errors and posted an acknowledgment on the other forum, but the dimensions for the GEM-46 Boosters have never been changed on the drawing.
Does anyone have the actual dimensions for the GEM-46 boosters ?
Actual diameter ( I have heard 45.898" & 1170mm /46.06", but that is unconfirmed ) . . . Motor Case Length . . . Nose Cone Length and "shoulder" contour ( "shoulder" is not present on the GEM-40 ). . .
Overall lengths for the 3 different GEM-46 configurations (fixed/ground-ignited / 495.1", vectorable/ground-ignited / 493.9", & fixed/air-ignited /511.2" ).
I am assuming that the variety in overall lengths are due to the different nozzle configurations, with casing dimensions and nose cone details remaining constant.
I have the ATK Space Propulsion Products Catalog, but it is not specific in dimensions . . .
Thanks !
