A fully engineered smartphone enclosure integrating a card-based swappable battery architecture, intelligent charging control, and embedded protection systems for uninterrupted mobile power delivery.

Localized extreme-heat TPS concept for oxidizing environments: Hf-rich UHTC hot-face, oxidation-control transition, strain-decoupled support, optional hotspot relief, and staged coupon-to-subscale validation.

Reproducible aerocapture + EDL braking trade studies with audit-grade telemetry and verification—compare baselines, enforce q/g/heating constraints, and rerun results from a single config.

Provide reproducible aerocapture and EDL deceleration architectures with verified models based on clear constraints and telemetry data.
