Fig. 17 - Ring in Ring bending Lightweight Spacecraft and Solar Sail Structure
Fig. 17 shows, how the Inner Ring structur 5 of the Solar Thruster Sailor design is held in the center of the Outer Thruster Ring 1.
The Inner Ring structure should be a Magazine Docking and Payload station which is not shown here.
The threads 5.12 and 5.9.3.1 are holding the center structure in the spacecraft. It does not require to use masts, booms or struts to get a strong construction. Just the stiff, Outer Ring takes the load which getīs spreaded onto it through some threads. Here I am counting on the "10-times stronger than steel" of the CNT-material when taking on pulling forces.
I canīt imagine another structure as lightweight while providing as much sail area and also carrying a large docking and payload volume.
The threads 5.9.3.1 are also thought to center the Inner Ring structure into the outer Ring with the help of the winches 5.9.3, so that constructing the craft would be a lot easier.
The Inner Ring Structure 5, which consists out of 3 rings 5.a-5.c carries also solar cell panels 5.11 which could be double sided. Along with double side aluminum coating of the sail cloth, the craft would produce power and thrust, regardless which side points to the sun. This helps to prevent too rapid turns when orbiting about Earth or other planets or moons.
The Inner Ring construction is also stiff like the Outer Ring.
When the spacecraft carries a sail, it is a separate layer which is shown on Fig. 13.

If used for a solar sail, the holding structure of the Inner Ring construction lies separate under the solar sail panels.
The Inner Ring Structure 5 consists of 3 Rings 5.a - 5.c which are held together with ring connecting pipes 5.9. The area between rings 5.b and 5.c is used up through solar panels 5.11, the area in the innerst ring 5.a is free for payload or daughter units. Those ring connecting pipes can go up and down off the ring plane also to form a volume for the docking and payload station.
