What we do
Four services. One discipline.
Four service lines covering the full lifecycle — from operational requirements to flight-ready aircraft, with EASA dossier in hand.
- 01 / 04
Mission Analysis & Consulting
From operational challenge to UAV system requirements. We define endurance, speed, payload, sensors, comms — before any airframe is selected.
- 02 / 04
Aerodynamic Analysis & Optimization
Wind-tunnel-grade analysis. Wing planform, control surface authority, propulsion integration — optimized for your mission envelope.
- 03 / 04
Testing & Certification Support
Ground tests, flight tests, EASA SORA dossier preparation. We get your platform through Specific Category authorization.
- 04 / 04
Full System Integration
Airframe, propulsion, avionics, sensors, comms, navigation, autonomy, GCS — integrated into one reliable system.
Our story / 2002—2026
From models to the industrial sky.
It started in 2002, in an aviation-modelling club — the first hands-on experience of designing and building aircraft. That grew into five years of aerospace engineering at the National Aviation University in Kyiv, a first survey drone, and fixed-wing platforms for aerial chemical application — followed by a decade in civil aviation, the drone work never set aside. At Clearsky Aerotech that real aviation experience becomes reliable, long-endurance UAVs for critical-infrastructure monitoring.
Talk to engineering- Ch. 012002Aviation modelling club.Where it began — designing and building model aircraft by hand. The first feel for airfoils, structures, and the discipline of making something fly.
- Ch. 022007—2012National Aviation University, Kyiv.Five years of aerospace engineering. A first survey drone, and fixed-wing platforms designed for aerial chemical application — UAV work, years before it was an industry.
- Ch. 032012—2022A decade in civil aviation.Ten years of professional aviation experience — with drone design and construction never set aside.
- Ch. 042024Clearsky Aerotech.The hobby becomes the company. Real aviation expertise turned toward professional, industrial fixed-wing UAVs.
- Ch. 052026CSK-01.Industrial hybrid-turbine UAV. Target endurance of 12 hours, 12 kg payload capacity, EASA SORA 2.5 ready.
