When Radical Efficiency Takes Flight: Damjan Zabovnik on Reinventing VTOL Aviation
What if the future of flight didn’t emerge from massive aerospace corporations — but from a physicist who once set world speed records on a human-powered bicycle?
In this episode of Industry Ignited, host Dr. Leeanne Aguilar sits down with Damjan Zabovnik, CEO of EV Corporation, to explore how radical efficiency, persistence, and unconventional thinking are reshaping electric vertical takeoff and landing (eVTOL) aircraft and heavy-lift drones.
Damjan is a physicist, inventor, and entrepreneur whose hands-on experience spans aerodynamics, rapid prototyping, UAV systems, autonomous flight, and AI. His journey is a powerful reminder that breakthrough innovation often comes from those willing to challenge assumptions — and test ideas relentlessly in the real world.
From Human Power to High Performance Flight
Before aviation, Damjan spent more than a decade designing and racing human-powered vehicles, eventually setting a world record of 54.1 miles in one hour from a standing start. That experience fundamentally shaped how he thinks about efficiency.
Unlike engines, the human body has strict power limits. There’s no room to “cheat” physics. If a vehicle performs well, it must be aerodynamically sound. Through wind tunnel testing, field data, and iteration, Damjan learned exactly how far efficiency could be pushed — and how elegant design often emerges where physics and simplicity meet.
That philosophy would later become the foundation of his work in aviation.
Why Simple Designs Win
As both a physicist and a builder, Damjan believes theory and practice must go hand in hand. Designing something that can’t be built is wasted effort. By staying close to prototyping, he naturally gravitated toward simpler, more reliable systems with fewer moving parts.
This mindset carried through everything he built — from transportation systems to energy-efficient structures — and eventually into vertical flight.
The Leap into VTOL
Inspired by early drone experimentation and the rise of companies like Joby Aviation, Damjan began exploring VTOL designs around 2014. The real turning point came years later, when collaboration with aviation engineers and participation in competitive challenges pushed his concepts from experiments into serious development.
Through multiple design iterations — and many failures — Damjan refined a novel approach centered around a circular wing VTOL architecture.
Why a Circular Wing?
The circular wing concept solves multiple problems at once.
Structurally, a circle supports itself, unlike traditional wings that require reinforcement at the tips. Aerodynamically, it allows large propellers to draw airflow efficiently through the center. Practically, it creates a compact aircraft with a smaller footprint — making it easier to transport, store, and deploy in tight spaces.
This approach also protects the most critical components: the main lift propellers. By integrating efficiency, structure, and safety into a single design, the aircraft achieves both vertical lift capability and fixed-wing efficiency during horizontal flight.
Learning Through Failure
Damjan openly shares that progress was anything but linear. Early prototypes struggled with stability, particularly in crosswinds. Control-surface-based designs proved fragile, forcing a shift toward multi-propeller configurations inspired by multicopters.
Each crash and redesign reinforced an essential lesson: persistence matters, but flexibility matters just as much. Being willing to abandon promising ideas in favor of better ones became a leadership skill, not just an engineering decision.
Why Hybrid Lift Matters
Traditional helicopters are inherently inefficient due to turbulent airflow. EV’s hybrid approach — combining large, slow-rotating propellers for vertical lift with wing-based laminar flow for forward flight — dramatically improves efficiency, range, and payload capacity.
Fewer exposed arms, fewer small propellers, and cleaner airflow translate directly into better lift-to-drag ratios and lower energy consumption. This makes EV’s platform especially well-suited for heavy-lift and long-range missions.
Entering the Market Through Emergency Response
Rather than starting with passenger transport, EV Corporation is targeting emergency and first-response applications first.
Wildfires, floods, remote medical deliveries, disaster relief, offshore infrastructure, and conflict zones all require rapid deployment and heavy payload capabilities. With lift capacities ranging from 300 to 500 pounds, EV’s aircraft fills a critical gap in today’s drone ecosystem.
Interest from California agencies, offshore energy operators, and even the Ukrainian government highlights the urgency and relevance of this technology.
Autonomy at the Edge
One of the most compelling aspects of EV’s platform is its onboard AI and edge autonomy. In disaster environments, connectivity is unreliable — or intentionally disrupted.
By enabling aircraft to detect, assess, and respond autonomously (such as suppressing a wildfire in its earliest stages), EV reduces dependence on cloud systems and communication links. This autonomy isn’t just a feature — it’s a necessity for resilience and speed.
Validation and Momentum
Receiving a NASA SBIR Phase I award marked a turning point for the company. The grant accelerated development and provided critical credibility, transforming external skepticism into serious engagement from partners and investors.
With validation came choice — and with choice came new leadership challenges.
Leadership, Endurance, and Long-Term Vision
Bringing on a co-founder was one of the hardest decisions Damjan made. It required trust, humility, and a willingness to share control — but it also strengthened the company’s resilience, broadened expertise, and reduced single-founder risk.
Balancing intense focus with family life remains a challenge, but Damjan is clear-eyed about his strengths: long-term endurance, obsession with meaningful goals, and the ability to keep digging when progress is slow.
For innovators with unconventional ideas, his advice is simple but hard-earned: don’t give up — but don’t be stubborn either. Listen, adapt, and persist.
