NASA Challenge : Rotating module

Optimization is the key word in defining my solution. By using fixed bulkheads as shown in gray below, we lose a lot of space between them (purple), but we can't fill them with cargo, otherwise the crew will have to move too many CTBs to access the ones behind.My solution makes use of a very large proportion of the unoccupied space between the fixed structures, while ensuring that the crew can directly access the CTB they want without having to move a single one.The rotating structures can be kept fixed during take-off, and are manually operated once in space, avoiding the use of electronics too heavy for the whole system.The rotating assembly is composed of two parts without cargo, allowing the crew to reach the CTBs positioned on the 3 fixed bulkheads.In one of the rotating structures we can store 12 Payloads and 2 x 6.0 CTB and in the other 4 x 4.0 CTB + 2 x 6.0 CTB as can be seen in the sectional view below.In our system as a whole, we can therefore store a very large quantity of cargo.
