What they'll ask you

Generated from the brief's own wording and the competition's published rules, never from a guess about what this ministry prefers.

Exact engine performance maps and thermodynamic equations for the specific MALE UAV piston engine?
The brief never answers this, so a panel will. Whatever you decide, say it the same way twice.
Required data formats and protocols for telemetry input?
The brief never answers this, so a panel will. Whatever you decide, say it the same way twice.
Specific hardware specifications for the ground control station deployment?
The brief never answers this, so a panel will. Whatever you decide, say it the same way twice.

Has any part of this been shown at a previous event, hackathon or college project?
The guidelines are explicit: your solution must not have appeared in any previous event or programme, of any sort. A recycled project is what a team under time pressure reaches for.
The brief asks for digital twin core. How would you build that?
Decoded from SIH26054 itself: Establish a virtual engine model that ingests live data and synchronizes with physical engine parameters. The brief asks for it by name.
The brief asks for health monitoring system. How would you build that?
Decoded from SIH26054 itself: Continuously assess sub-system conditions and generate health indices for parameters like RPM, CHT, EGT, and oil pressure. The brief asks for it by name.
The brief asks for fault detection analytics. How would you build that?
Decoded from SIH26054 itself: Run AI models to detect anomalies, predict component failures, and estimate remaining useful life. The brief asks for it by name.
The brief asks for simulation engine. How would you build that?
Decoded from SIH26054 itself: Simulate engine behavior and reproduce historical missions under different environmental conditions. The brief asks for it by name.
The brief asks for visualization dashboard. How would you build that?
Decoded from SIH26054 itself: Provide a user interface for operators and engineers to view real-time health status, fault alerts, and maintenance advisories. The brief asks for it by name.
Where does your data come from: a published source, one you collect, or one you generate?
No dataset is attached to this problem statement, so sourcing it is part of the work and nobody told you that.
Why not use what already exists? Name the closest thing to this that is already running.
A team that has not named the alternative themselves is answering this for the first time in the room.
Which single thing will you demonstrate end to end, start to finish, with nothing skipped?
Ours, not a rule: a narrow thing that fully works survives questioning better than a broad thing that half works. If nobody on the team can name it, that is the finding.
Show me this working: the jury will check whether the system can process telemetry data to monitor specific engine parameters like CHT, EGT, and vibration, detect anomalies before failure, and support post-flight mission replay through a functional dashboard.
This is the evaluator read for your problem statement, decoded from the brief's own wording.

The government's original description (821 words)

• Background: Medium Altitude Long Endurance (MALE) UAV are increasingly being deployed for Long-duration intelligence, surveillance, reconnaissance (ISR). Communication relay maritime surveillance and strategic defence missions Reliability and availability of propulsion systems are critical for mission success because piston-engine failures during flight may lead to mission abort, asset loss, or unsafe recovery conditions. Conventional engine monitoring systems used in UAVs are primarily thresholdbased and reactive in nature. These systems generally indicate failures only after abnormality has already occurred. Present approaches also have limited capability to estimate remaining useful life (RUL) predict degradation trends, or simulate mission-wise engine behavior under varying environmental and operating conditions. A Digital Twin (DT) framework for aero piston engines can significantly improve predictive maintenance, operational reliability, mission planning, and life cycle management by creating a continuously synchronized virtual representation of the physical engine using real-time sensor data physics-based models and AI/ML techniques. The proposed problem aims to develop an indigenous Digital Twin framework suitable for deployment in MALE UAV ground control and health monitoring architecture. The solution should support real-time engine state estimation, anomaly detection degradation tracking, faultprediction, and mission replay capability. • Description: Develop a scalable and modular digital Twin System for an aero piston engine used in MALE UAV applications.
