The Final Design Review (FDR) reports on the senior design project undertaken by a mechanical engineer senior at California Polytechnic State University, San Luis Obispo. The project seeks to assist Maxar’s need for a lift fixture for their spacecraft that will locate its center of gravity and move the pick point directly over the center of gravity (C.G.). This will allow the crane to attach to this point and lift the spacecraft without any swinging motion that could damage the spacecraft or harm personnel working near it. Their current solution is creating a new lift sling for each time they lift the spacecraft. This takes time away from their teams as they must analyze the spacecraft’s mass properties and then build a corresponding lift sling. The scope of the project was to design, build, and test a proof-of-concept lift sling for Maxar.

Detailed CAD models and a working prototype of the lift fixture were created. Testing of the lift fixture demonstrated the feasibility of a one-size-fits-all lift sling that can be scaled up for spacecraft.
