Mass efficient reaction wheel assembly systems including multi-faceted bracket structures

A Reaction Wheel Assembly (RWA) system, comprising:

• a multi-faceted bracket structure, comprising:
• a first interchangeable panel including a first mount bracket;
• a second interchangeable panel fixedly joined to the first interchangeable panel and including a second mount bracket;
• and
• a vehicle mount interface at least partially defined by the first and second interchangeable panels;
• and
• first and second RWAs mounted to the first and second mount brackets, respectively,
• wherein the first interchangeable panel comprises an RWA-support face in which an opening is formed, and
• wherein the first mount bracket comprises:
• a plurality of cross-beams extending within the opening;
• and
• a central hub portion integrally formed with the plurality of cross-beams and substantially concentrically located within the opening.

A Reaction Wheel Assembly (RWA) system, comprising:

• a multi-faceted bracket structure having a centerline, the multi-faceted bracket structure comprising:
• a first bracket structure portion defining a first mount bracket;
• and
• a second bracket structure portion defining a second mount bracket, the first and second bracket structure portions opposed about a midline plane containing the centerline, and
• first and second RWAs attached to the first and second mount brackets, respectively,
• wherein the first and second mount brackets each comprise:
• a body having an inner circumferential edge defining an opening;
• a cartridge hub feature positioned within the opening;
• and
• a plurality of cross-beams extending from the inner circumferential edge to the cartridge hub.
