Overview
Interactive TRL (Technology Readiness Level) assessment dashboard quantifying the maturity of maintenance technologies across Reusable Launch Vehicles (RLVs). Evaluates 8 maintenance technology categories across 5 vehicles — producing 40 individual TRL assessments with derived gap analysis and prioritised recommendations.

Context
Built in the context of DLR Institute of Maintenance and Modification research on maintenance considerations for Reusable Launch Vehicles. As stated in the DLR research brief, maintenance technology for RLVs "remains in its infancy" — this dashboard quantifies exactly where the gaps are using the NASA/ESA TRL framework standard at DLR, ESA, and NASA.
Relevance
Directly mirrors DLR research tasks: assess and quantify maintenance technology maturity for RLVs Applies the industry-standard NASA/ESA TRL framework used operationally at DLR Identifies critical gaps (TRL ≤ 3) requiring immediate R&D investment Supports life cycle analysis and maintenance technology roadmap planning Demonstrates structured, data-driven approach to scientific technology assessment
