2.3.16-6 Level 2 Tasks

Tasks Applicable Mission Phases Description SFWC Artifacts References
2.3.16-6-1 Ensure the cable and harness weight estimates are done properly and include margin and contingency Phase B | Phase C | Phase D1 | Ensure the cables and harnesses weight estimates are all inclusive (wires, connectors, contacts, wrappings, screws, etc.) Ensure the total weight estimate includes all cables and harnesses elements. Ensure the weights are updated as the actual weights are available. NA NA TOR-2006(8506)-4494, Space Vehicle Systems Engineering Handbook, Electrical Power and Distribution chapter, Cabling section
2.3.16-6-2 Ensure the cable and harness bundle diameters are estimated correctly Phase B | Phase C | Ensure cables and harnesses bundle diameter estimates include all the wrappings, splices if allowed, any components included in the harnesses, and adequate margin. NA NA TOR-2006(8506)-4494, Space Vehicle Systems Engineering Handbook, Electrical Power and Distribution chapter, Cabling section
2.3.16-6-3 Ensure the cables and harnesses voltage drop analyses are done properly and includes margin Phase B | Phase C | Ensure the wire gauge is sized properly with de-rating factors. Ensure the wire lengths are reasonable from mechanical models. NA NA TOR-2006(8506)-4494, Space Vehicle Systems Engineering Handbook, Electrical Power and Distribution chapter, Cabling section
2.3.16-6-4 Ensure the cable and harness thermal analyses are adequate Phase B | Phase C | Phase D1 | Ensure the interior wires and cables can adequately dissipate the heat. NA NA TOR-2006(8506)-4494, Space Vehicle Systems Engineering Handbook, Electrical Power and Distribution chapter, Cabling section
2.3.16-6-5 Ensure the cable and harness dynamic analyses are adequate Phase B | Phase C | Ensure the cables and harnesses bundles are adequately secured. NA NA TOR-2006(8506)-4494, Space Vehicle Systems Engineering Handbook, Electrical Power and Distribution chapter, Cabling section
2.3.16-6-6 Ensure the cable and harness Fault Mode and Effect Analysis (FMEA) are adequate Phase B | Phase C | Ensure the FMEA include the system level analysis and not just the connectors and bend pins. Any unit that has connectors that are critical items would make the mating harnesses or cables critical items as well.
