VTOL/eVTOL transition aerodynamics when the corridor is the risk
Custom transition-corridor aerodynamics solvers for VTOL and eVTOL — hover-to-cruise interaction, control authority, and envelope protection for programmes worldwide.
Built for: eVTOL OEMs, VTOL startups, flight sciences transition teams, and certification-minded programmes worldwide
Why OEMs commission custom solvers
Hover and cruise are hard; the corridor between them is where programmes stall. eVTOL and VTOL teams need transition aerodynamics and control authority models that speak to gated reviews — not only cruise CFD.
Hendoi builds custom VTOL/eVTOL transition aerodynamics products: interaction models, corridor cases, and hooks to 6-DOF, props, and powertrain energy budgets.
Flight sciences and programme leads get English docs, reproducible corridors, and IP ownership for tools built around their configuration.
Industrial pain points we remove
Cruise CFD without a transition productThe schedule risk lives in the middle of the envelope.
Control authority surprisesTilt, lift fans, and wingborne flight need one coherent story.
Envelope protection as a sloganReviews ask for limits you can regenerate.
Weak coupling to energy and propsTransition loads the battery and prop maps hard.

Frequently asked questions
Tiltrotor, lift+cruise, or tailsitter?
We scope the configuration class in the first workshop.
Full unsteady CFD?
We hybridise — product cases first, high-fidelity where it changes the gate.
Certification language?
We write cases and docs so programme and safety stakeholders can follow.
Global programmes?
English milestone demos for flight sciences and leadership.
