Completed TRL 3 (started at 2, targeting 3)
Characterization of multi-body aerodynamic interactions between separating bodies in high-speed flow is critical for improving trajectory prediction capabilities of de-orbiting space debris and precluding re-contact of rocket boosters during payload ascent. State-of-the-art tools rely on unvalidated static computational fluid dynamics (CFD) databases to simulate body trajectories, and a dearth of analytical modeling prevents parametric study of the key elements governing separation events. This two-phased program seeks to remedy the current knowledge gaps with a multi-disciplinary approach involving free-flight hypersonic wind tunnel testing and dynamic CFD simulations. By first focusing on separation of agglomerated ellipsoidal geometries as space debris analogs and then models more reminiscent of realistic flight vehicles, the proposed program will provide validation data for the static CFD methodology and develop separation models based on observed aerodynamic interference effects. This research aligns with the needs specified in TABS elements 9.4.5.8, 9.4.5.9, and 9.4.5.12 of the 2015 NASA Technology Roadmap.

Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 3) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
