Structure Verification 0310-0530

Continued verification activities for the Structure Subsection items 0310 through 0530

All components ultimately mount to the structure. See Assembly plan for details.

RBF Pin is oriented on the +Y face of the satellite for ability to be accessed while satellite is within deployer. ICD Page

Part list expanded past using only 2-56, 4-40 and 6-32 fasteners. Team has internally approved use of the other fastener types used by the satellite. Part List

additional fastener types are as follows: 1-64 and M1x0.25

The RBF tag is placed on the +Y face of the satellite using nanorack axis definition. Refer to ICD Page

No portion of the satellite is pressurized and all modules have access to space.

Mitigation strategy, if any portion of the satellite is found to be at risk additional venting holes can be added to increase the venting ratio.

The Final assembled satellite must undergo and survive a TVAC depressurization test. Satellite must survive test of 104.8 to 0 kPa at a rate of -1 kPa/sec.

The worst case Venting submodule is the ADCS. It's internal volume is approximately 52*96*96 = 479232 mm^3. The venting area is the sum of the hole areas and is 748 mm^2. the vent ratio is then 64 cm which is much less than the 5080 cm limit.

The as-built final satellite will be placed on a set of rails(hard flat surface) on a workbench with no more than a 1cm gap between the top of the rails and the workbench surface. The workbench, rails and satellite will all be electrostatically isolated. The satellite will be slowly slid along the Z-axis until the satellite begins to tip. The tipping point will then be measured and this value will be translated into the satellite coordinate system and confirmed to be less than 6cm from the satellite Center of Mass

Note, care will need to be taken during this test to ensure that the solar panels will not contact the rails and that when the satellite tips none of the external satellite components will contact the table or rails.

Bill of Materials was reviewed to ensure only materials with CVCM < 0.1% BOM

Rail contact area with deployer requires 6mm in both x and y axis. Current rail design provides more than enough contact area per the ICD. link

Rail ends as designed are flat. Link

Rails as designed will meet the 6mm x 6mm area requirement. Link

Rails as designed will have coplanar ends. Rails are all same length and mount at same locations Link
