TABLE 4.1-i
Table 4.1-1 presents the mass characteristics for the SM/SPS propellant
tanks.
The following units apply to the indicated headings:
Height of Propellant - Inches Mass of Propellant - Pounds
Tank Volume Unstretched - Ft3 Center of Mass - XA Coordinates - Inches
Tank Volume Stretched - Ft 3 Moment of Inertia (Iyy) - Slug-ft 2
Further, Moment of Inertia IZZ - Moment of Inertia Iyy; Moment of Inertia IXX-0.0
for all propellant weights; tank pressure used in calculating this table was
175±5 PSIA, propellant temperature was 70°F, density for fuel was 56.43 ib/ft 3,
and oxidizer density was 90.21 ib/ft 3.
The YAand Z A Center of Mass components for the individual tanks are constant
and are as follows:
YA (inches) ZA (inches)
Fuel Storage -14.8 -47.8
Fuel Sump -48.3 -6.6
Oxidizer Storage 14.8 47.8
Oxidizer Sump 48.3 6.6
