Rotorcraft solvers for helicopters, UAVs, and eVTOL rotors
Custom rotor aerodynamics, BEM/free-wake, rotor trim, and helicopter performance solvers for rotorcraft programmes, eVTOL teams, and OEM rotor desks worldwide.
Built for: rotorcraft and defence aero teams, eVTOL developers, and global helicopter/OEM rotor aerodynamics offices
Why OEMs commission custom solvers
Rotor performance and trim are specialised — generic CFD seats rarely replace a productised BEM/free-wake and trim stack. Rotorcraft programmes and OEMs worldwide need owned methods for design reviews and academies.
Hendoi builds custom rotorcraft solvers: rotor aerodynamics, BEM vs free-wake strategies, rotor trim, and helicopter performance workflows for design and training.
Enterprises get English docs, validation narratives, and IP suited to industrial buyers worldwide.
Industrial pain points we remove
BEM vs free-wake confusionTeams pick methods without a productised decision path.
eVTOL rotor trim not repeatableMulti-rotor configs need trim products, not one-off notebooks.
Performance charts executives distrustReviews need stakeholder-ready helicopter performance outputs.
Academy tooling gapsUniversities need teachable rotorcraft labs.

Frequently asked questions
BEM enough for early eVTOL?
Often yes for early trades; we escalate to free-wake/CFD when your gates require it.
defence rotor programmes?
Yes — on-prem scoping available.
Multi-rotor support?
Yes, when scoped — trim architectures differ from single main rotor.
Global OEM delivery?
Milestone plans with English validation packs.
