Hindustan Aeronautics Limited has introduced a new DRISHTI challenge focused on creating an AI- and Augmented Reality (AR)-driven visual inspection solution for the TPE331-12B engine powering the HTT-40 trainer aircraft. The program seeks to transform traditional inspection processes by reducing manual intervention and enhancing precision, efficiency, and reliability in engine maintenance.
At present, inspection workflows and Engine Check List (ECL) management during induction and dispatch remain predominantly manual, leading to operational bottlenecks and increased chances of human error. HAL has noted that manual execution of ECL tasks is both time-consuming and susceptible to overlooking critical inspection parameters, including foreign object debris. The manual identification and tracking of component serial numbers further complicate the process, raising the risk of inconsistencies.
Manual visual inspections also introduce variability in quality, with the potential for missed defects and inconsistent reporting standards. Considering the technical complexity of engines such as the TPE331-12B, even minor undetected anomalies can adversely affect performance and safety.
The DRISHTI initiative aims to address these challenges by combining AI-powered computer vision with AR-enabled assistance tools. The envisioned system will support automated defect identification, wear detection, and component recognition through advanced image analysis. Machine learning capabilities will help standardize inspection procedures, ensuring uniform and repeatable outcomes.
The integration of AR technology will provide technicians with real-time visual guidance, overlay-based instructions, and contextual data within their line of sight, improving accuracy and reducing dependency on manual interpretation. It will also enable remote collaboration with experts for complex inspections.
Additionally, the system is expected to enhance coordination during induction and dispatch phases by streamlining workflows, enabling real-time monitoring, and automating documentation, thereby reducing delays and improving process efficiency.
Overall, HAL aims to leverage this initiative to accelerate turnaround times, minimize maintenance-related errors, and improve operational readiness of the HTT-40 fleet, in line with the growing adoption of advanced digital MRO solutions in the aerospace industry.
