The rocket equation has two parts structural efficiency and motor performance. Since the beginning of our project we have spent considerable effort thinking about structural efficency.
Clearly modern composite structures hold real promise for improving structural efficiency. I've dabbled in composite structures but I am very much a beginner. The tanks produced by professionals like Scorpius Launch Systems/Microcosm are both amazingly functional and beautiful. It would take me a decade to acquire that level of expertise. The recent composite coupons I tested for peroxide compatibility were fabricated by Microcosm/Scorpius. I'm currently riding home from a meeting at their facility where we finished the details of a joint development program to build peroxide compatible liner less tanks.
I think this is a win win for both parties Scorpius will get a new product line and we will gain access to world class tanks.
