Predictive Maintenance for Turbine Engines — Case study cover image

The Challenge

Unscheduled maintenance was costing millions in penalties and flight delays. Existing sensors detected faults too late to prevent grounding.

Client Overview

A top-tier engine manufacturer needed to reduce the cost of power-by-the-hour contracts by preventing unplanned engine removals.

Global fleet
Safety-critical
High cost of failure
Terabytes of sensor data

Solution Components

Digital Twin Engine

Physics-based models calibrated with live sensor data for each serial number.

Anomaly Detection

Unsupervised learning catching vibration patterns invisible to rule-based logic.

Maintenance Prescriber

Recommending specific part replacements to ground crews.

Challenges & Risks

1

False Positives

Alerting too often would destroy trust; models had to exceed 95% precision.

2

Data Volume

Processing 2TB of flight data per day required edge-to-cloud pipelines.

Key Impact

$12M
annual savings in avoided AOG (Aircraft on Ground) fees
50
flight-hours lead time for failure warnings
30%
reduction in spare part inventory costs
Zero
safety incidents related to engine failure

The Solution

We built a hybrid AI-physics digital twin for each engine. It analyzes vibration, heat, and pressure in real-time to forecast component life, alerting crews to repairs weeks before failure.
