Beyond Gravity develops separation systems for launch vehicles and space crafts. One type of separation system is the Payload Adapter System (PAS), it is used to separate space crafts from launch vehicles. The two stages the separation system holds together must be able to transmit data between each other, this is done by cables and connectors. The structure on the PAS that holds these connectors is called the umbilical tower, this structure allows for movement of the connectorsto prevent them from taking damage from shocks that occur during the launch sequence. This movement ability is called float.

The aim of the project was to redesign the umbilical tower of the PAS to increase its floating capabilities, as well as optimizing the load path and material selection for the construction.

An acclaimed methodology for concept development and product design was used to guide the project forward in a structured fashion. The current design was analysed from which needs and requirements were established. This led to the development of new concepts which were ranked based on the stated requirements. Some concepts were similar to today’s design while others weremore experimental and unconventional. This approach was used in order to explore alternative perspectives and gain fresh insight into the design process. The exact dimension, overall setup and material used were determined through calculations to ensure the design’s strength and endurance.

A few different solutions were examined, but the resulting concept consisted of an interface with larger dimensions and an improved setup of washers in a material better suited for the function. The results this project presents should be regarded as an initial step toward the continued development of the umbilical tower.
