Vertical-Axis Wind Turbine for Electric Aircraft Patent Landscape
Vertical-Axis Wind Turbine for Electric Aircraft Patent Landscape in 2026
The intersection of vertical-axis wind turbine technology and electric aircraft is an extremely early-stage niche with just one patent family on record, filed by a single individual inventor through the PCT system in 2019. No major corporate or institutional players have staked a claim, leaving the space essentially open but also signalling that validated commercial demand has yet to emerge.
One inventor, one family: a niche without established incumbents
The corpus contains a single patent family, attributed entirely to Gubanov Aleksandr Vladimirovich, who therefore holds a 100% share of the top-ranked filers’ combined total. There is no competitive ranking to compare — this is effectively an un-contested filing space.
With only one entry in the applicant ranking, no tier-gap analysis is meaningful. The absence of corporate, institutional, or state-owned enterprise filings is the most notable structural observation.
| # | Applicant | Patent families | Share |
|---|---|---|---|
| 1 | Gubanov Aleksandr Vladimirovich | 1 |
The sole filer’s position implies no defensive blocking by established aerospace or wind-energy incumbents, but equally implies that the technology has not yet attracted the R&D investment that typically precedes commercialization.
The most recent filing activity may be subject to publication lag, so absence of records beyond 2019 should be interpreted cautiously rather than as a definitive signal of zero interest. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A single 2019 filing spike with no subsequent activity on record
The annual filing trend shows one event — a single family filed in 2019 — with no activity detected in any surrounding year. The technology composition reflects the dual classification of that one family across lighter-than-air aircraft and wind motor classes.
Annual filing trend
One family appeared in 2019; all other years in the window record zero filings. Given that recent years are typically under-counted due to publication lag, the absence of post-2019 records is an inconclusive signal and should not be read as confirmed zero activity after 2021.

The single family is classified under both B64B (lighter-than-air aircraft) and F03D (wind motors), reflecting the hybrid nature of the invention. The equal weight of these two branches indicates that neither airframe nor turbine classification dominates — the family straddles both domains.

AERO-energystat
Invention relates to the field of high-altitude wind energy. Aero-energystat comprises an aerostatic module in a soft gas-filled shell, a wind-power unit suspended under the shell, altemating-air-propeller electric aero-engines of the traction and opposite rotation, tether cables and rope-cable stretched from module to mooring assembly.

What the structure means for R&D entry decisions
A corpus of one family tells an R&D team as much about what is absent as what is present. The four structural reads below help frame where risk and opportunity sit.
Pre-commercial: activity peaked in 2019 and has not resumed
The lifecycle stage is classified as Decline, with the sole filing peak occurring in 2019 and no subsequent families detected. This is less a mature-market decline than a pre-commercial niche that never developed critical mass. An entrant today would face no incumbent blocking, but also no established technical community to reference.
Lifecycle: DeclineTotal concentration in one individual inventor
The top five filers account for 100% of the hundred largest filers’ combined total — because there is only one filer. No corporate assignees, no universities, and no government research institutes appear in the record. This concentration is a signal of embryonic rather than mature activity.
HHI: MaximumNo co-applicant activity detected
Evidence pending: the collaboration data contains no co-filing relationships. The single family is attributed to one individual with no co-assignees, suggesting this is an independent inventor effort rather than a consortium or joint-development programme.
No co-filers on recordPCT only — no national-phase entries detected
The sole filing was made through WIPO (PCT), which preserves the option to enter national phases but does not confirm granted protection in any jurisdiction. No country-level entries appear in the evidence, so the effective territorial footprint is currently undefined.

Gubanov Aleksandr Vladimirovich: sole filer across both technology branches
With only one entity in the applicant ranking, conventional leader-vs-challenger framing does not apply. The description below characterises the sole filer and notes the absence of any challenger.
Gubanov Aleksandr Vladimirovich
The sole applicant on record, holding 1 patent family filed via PCT in 2019. Technology emphasis spans B64B 1 (lighter-than-air aircraft), F03D 1 (wind motors), and F03D 9 (wind motors — special applications). Applicant momentum data is not available for this filer. As an individual inventor, trajectory and resource base are not derivable from the patent record alone.
families: 1No challenger identified
No second applicant exists in the corpus. Corporate, academic, and government filers are entirely absent from this space, making challenger identification impossible from current evidence. This absence represents the most significant structural feature of the landscape.
families: 0Under-served adjacent branches worth monitoring
The whitespace candidate list from the evidence is empty, so the observations below are drawn from the sparse IPC coverage visible in the existing record and plausible technical adjacencies — they are observations of relative sparsity, not validated opportunities.
B64C — fixed-wing and rotary-wing airframe integration
The single family is classified under B64B (lighter-than-air) rather than B64C (aeroplanes, helicopters), leaving the more commercially active fixed-wing and eVTOL airframe integration space unaddressed in this topic. Any entrant seeking to apply vertical-axis turbine regeneration to conventional electric aircraft aerodynamics would find B64C sub-classes essentially unoccupied relative to this niche. Entry plausibility depends on resolving fundamental aerodynamic interference questions before filing.
Search this in Eureka →H02J — onboard power management and storage integration
No power-electronics or energy-storage classification appears in the single family on record. An onboard VAWT generating supplemental electricity for an electric aircraft must interface with battery management and power conversion systems (H02J class), yet this branch is entirely absent from current filings. The technical value is clear — regenerative range extension — but the engineering feasibility barriers account for the gap. Monitoring H02J filings combined with B64 or F03D claims would flag any new entrant addressing this integration challenge.

Frequently asked questions
The current evidence identifies 1 patent family in scope, filed by a single individual inventor via the PCT system in 2019.
Gubanov Aleksandr Vladimirovich is the sole applicant on record, holding the one patent family identified in this niche. No corporate or institutional filers appear.
The single family was filed through WIPO (PCT). No national-phase entries are detected in the current evidence, so territorial protection beyond the PCT application stage is unconfirmed.
The single family is classified under B64B (lighter-than-air aircraft) and F03D (wind motors, wind turbines), with sub-class coverage including F03D 1 and F03D 9.
The lifecycle stage is assessed as Decline, with the peak activity recorded in 2019 and no subsequent families detected. Given publication lag, post-2021 absence is inconclusive, but the overall picture is of a space that has not gained momentum.
No. The applicant ranking contains only one entry — an individual inventor. No aerospace OEMs, wind-energy firms, or research institutions have filed in this specific intersection based on current evidence.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown.
