Wind Turbine Blade Drone
Inspection Across India

Zero Rope-Access Risk

Eliminate the need for rope-access technicians at 80-120 m heights. Drone inspection is non-contact, non-invasive, and fully DGCA-compliant — no turbine shutdown required.

Inspect 8-12 Turbines/Day

A single drone crew inspects up to 12 wind turbines per day with sub-millimetre defect resolution. Traditional rope access manages 1-2 per day at 3-5x the cost.

Multi-Spectrum Detection

Simultaneous RGB (48 MP) and thermal imaging detects surface cracks, internal delamination, lightning damage, and leading-edge erosion in a single flight pass.

AI-Classified Reports

AiServe Wind auto-classifies blade defects by severity, location (pressure/suction side, leading/trailing edge), and recommended intervention timeline.

Blade Surfaces

All three blades — pressure side, suction side, leading edge, and trailing edge — captured at 0.3-0.5 mm/px resolution for crack, erosion, and coating damage detection.

Nacelle & Hub

External nacelle housing, hub assembly, spinner cone, and pitch system housings inspected for corrosion, oil leaks, seal failures, and lightning receptor damage.

Tower Structure

Full tower survey from base to yaw platform — identifying bolt corrosion, weld cracks, paint degradation, and flange joint anomalies.

Foundation & Base

Ground-level and low-altitude survey of foundation ring, grout condition, cable entry points, and drainage systems for early structural degradation.

Leading-Edge Erosion

Rain, sand, and insect impact erode the leading edge, reducing aerodynamic efficiency by up to 5% AEP. Our drones measure erosion depth and roughness profile across the full span.

Lightning Strike Damage

Receptor burns, tracking marks, and internal delamination from lightning strikes — India's monsoon belt makes this the most common blade failure mode. Thermal imaging reveals hidden internal damage.

Surface Cracks & Coating Failure

Longitudinal and transverse cracks in gelcoat and leading-edge protection tape, identified at sub-millimetre resolution before they propagate into structural damage.

Delamination & Debonding

Separation between laminate layers or adhesive bond failure at trailing-edge closures — detectable through thermal gradient analysis during solar-heated inspection windows.

Vortex Generator & Add-On Damage

Missing, broken, or displaced vortex generators, serrated trailing edges, and gurney flaps — each impacting aerodynamic performance when damaged.

Nacelle Component Degradation

Oil staining from gearbox leaks, corroded cooling systems, damaged anemometers, and lightning receptor wear — all captured in high-resolution nacelle orbits.

How much does drone wind turbine inspection cost in India?

Drone-based wind turbine inspection costs ₹15,000–₹30,000 per turbine depending on turbine height, number of turbines, and scope (blades only vs full nacelle + tower). This is 60–80% cheaper than traditional rope-access inspection which costs ₹60,000–₹1,50,000 per turbine including mobilization, safety crew, and downtime.

Do wind turbines need to be shut down for drone inspection?

No. Drones inspect wind turbines with blades in a parked (stationary) position but without electrical shutdown. There is zero production loss during inspection. Traditional rope-access methods require full turbine shutdown for 4–8 hours per turbine.

What types of blade defects can drones detect?

Our drones detect leading-edge erosion, lightning strike damage, surface cracks, gelcoat failure, delamination, debonding at trailing edges, missing vortex generators, and internal structural damage. Thermal imaging reveals sub-surface defects like moisture ingress and adhesive bond failures invisible to the naked eye.

How often should wind turbines be inspected?

Industry best practice recommends annual drone inspection for all operational wind turbines. High-exposure turbines in coastal or lightning-prone areas (Gujarat coast, Tamil Nadu) should be inspected every 6 months. Post-monsoon and post-cyclone inspections are critical for Indian wind farms.

Is drone wind turbine inspection DGCA-compliant?

Yes. All AiRotor Labs drone operations are fully DGCA-compliant with certified Remote Pilot Licenses (RPL), Unmanned Aircraft Operator Permits (UAOP), and flight permissions. We carry ₹1 Cr third-party liability insurance and follow DGCA UAS Rules 2021.

What is the report format and turnaround time?

AI-classified inspection reports are delivered within 48 hours. Reports include GPS-referenced defect maps, severity classification per DNV-GL and IEC 61400-5 standards, 3D blade defect overlays, and priority-ranked maintenance recommendations. Reports are available as interactive dashboards and PDF downloads.
