DIRECT TO PHASE II: Edge-Deployed Explainable Digital-Twin Condition Based Maintenance CBM+ Platforms for Carrier-Based Systems

Status changed from status: Open to status: Closed.

Q4 received detailed answers clarifying: AAG sensor data availability (historical examples provided post-award), existing sensor types (electric motor currents/voltages; water twister pressure/temperature), failure mode concerns (fatigue, fracture, bearing failure, electrical burnout), and ground truth data limitations with inspection opportunities at test sites.

Key Changes in Q&A:

Q1 Answer Updated: Clarified that Phase II will remain in test-site/laboratory environments (using existing data and potential testing at CONUS Jet Car Track Site), NOT shipboard. Shipboard transition would occur post-Phase II via PMA-251-funded Engineering Change Proposal.

Q4 Added: New comprehensive question with 8 sub-questions addressing critical technical details: AAG data availability (historical/live sensor data with labeled failures), sensor interfaces/protocols, failure-mode prioritization, ground-truth maintenance data, digital-twin fidelity expectations, prognostics definition (RUL vs. probability vs. degradation), explainability/HMI requirements, and LRU isolation accuracy standards.

No answers provided yet for Q4 — these remain pending government response and represent significant gaps for proposal planning regarding data access, modeling depth, and performance metrics.

Changes to Q&A Section:

Added 1 new question (Q1) clarifying that Phase II demonstration is expected to remain in test-site/laboratory environment during base period—shipboard installation with cybersecurity authorization is not required within Phase II base period.

Questions 2-4 were renumbered from previous Q1-Q3; all answers remain unchanged.

Added comprehensive answers to Q1-Q2; Q3 remains unanswered.

Q1 answered: Self-funded commercial work outside naval aviation acceptable if technically mappable to AAG; innovation focus left to offerors (both Digital Twins and plug-and-play API valued); existing AAG software is binary safety gate with motor and water-twister sensors.

Q2 answered: One award expected (direct-to-Phase-II); government provides schematics and existing data post-award; edge-only operation required (no cloud/data-link dependency); synthetic/subscale demonstrations acceptable; transition owner is PMA-251 for CVN-78 implementation.

Q3 still pending all eight sub-questions on data availability, sensor specs, failure priorities, ground truth, digital-twin fidelity, prognostics scope, HMI requirements, and LRU isolation standards.

Key Changes to Q&A:

Added Q1 (3 questions) addressing feasibility documentation acceptance, evaluation priorities between digital twins vs. plug-and-play API capability, and current baseline tools. Added Q2 (7 questions) covering award quantity, government-furnished data/environments, evaluation metrics, use of synthetic data, hardware constraints, and transition ownership. Q3 retained original 8 technical questions on AAG data, sensors, failure modes, ground truth, digital-twin fidelity, prognostics definition, explainability, and LRU requirements—now with clarified focus on ALRE subsystems beyond AAG.

Status changed from Pre-Release to Open

This Q&A clarifies eight critical technical requirements for Phase II proposals: applicants must understand what AAG data, sensor specifications, and failure modes the Government will provide; what ground-truth maintenance records exist; expected digital-twin modeling depth; specific prognostics outputs needed; and LRU isolation accuracy standards—enabling more targeted and realistic technical approaches.
