Octaweb Thrust Structure

Assembly

Bolted machined-aluminium structure mounting eight engines around one: it diffuses ~7,600 kN at liftoff, then takes the same engines’ retro-thrust and the leg loads at touchdown, sized for both directions. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
