Kestrel K-1 is an autonomous drone that flies every blade, finds cracks and leading-edge erosion down to 0.2 mm, and files the report the same day.
Downtime
Lost by one stopped turbine since you opened this page.
One stopped turbine loses about €1.73 a minute at the assumptions below.
Illustrative figures, not Kestrel data. Lost generation = rated power × capacity factor × power price, for the minutes the rotor is stopped. The rope-access bar is drawn at 8 hours to stand for “most of a working day”; the K-1 bar shows flight time only (3 × 11 minutes), not set-up.
Detection
That is about two sheets of paper. K-1 flies root to tip and logs every crack and every patch of leading-edge erosion by its position on the blade.
Sample blade with illustrative findings.
No week of waiting for photos to be sorted. The report reaches you the same day, finding by finding, metre by metre.

It does not repair blades. It tells your repair crew where to go, what they will find and how bad it is, before anyone ropes down.
You pick the turbine.Any turbine on your site. We bring K-1 and the crew to fly it.
We fly all three blades while you watch.About 11 minutes a blade, root to tip.
The report reaches you the same day.Every finding with its position, size and severity.
