Technical Abstract (Limit 2000 characters, approximately 200 words)

The innovation proposed here is a novel tank‑and‑aeroshell arrangement that exploits the latest composite manufacturing practices to advance the state‑of‑the‑art beyond what was possible during the NASA/Lockheed Martin X-33/VentureStar program (Ref. 1). By using advanced stitched‑composite design and manufacturing methods, a more efficient airframe design becomes possible that fundamentally addresses the manufacturing flaws, scale‑up challenges, and permeability issues that caused the X-33 tank specimen failure. The approach proposed in this SBIR is a highly‑integrated, load‑bearing, unitized skin‑stringer‑frame composite propellant tank that would be infused‑and‑cured in an oven, before being mechanically‑joined to a separately processed, discretely‑stiffened, carbon‑carbon aeroshell that would be capable of meeting the stringent structural weight fractions required for single‑stage‑to‑orbit vehicles. This SBIR Phase I proposal focuses on a few key development activities that would demonstrate the feasibility prospects of a unitized tank concept relative to the weight and permeability parameters that were achieved for the X‑33/VentureStar multi‑piece composite tank design approach.

Potential NASA Applications (Limit 1500 characters, approximately 150 words)

Innovative material and structural concepts that provide reductions in mass and volume for next‑generation space vehicles shows up as a key focus area in nearly all NASA and Air Force technology roadmaps for futuristic high-speed air vehicles.

Potential Non-NASA Applications (Limit 1500 characters, approximately 150 words)

The technology presented here is directly applicable to numerous Air Force and commercial launch applications.
