Custom engineering software · Worldwide industrial delivery
Flight mechanics solvers for trim, stability, and 6-DOF truth
Custom trim, stability, 6-DOF flight dynamics, trajectory, and missile flight solvers for aerospace OEMs, defence programmes, and flight sciences teams worldwide.
Built for: flight sciences desks, defence trajectory programmes, UAV ops teams, and global OEM flying-qualities offices
Why OEMs commission custom solvers
Trim, stability, and 6-DOF dynamics are where configurations become flyable products. Aerospace and defence programmes — and flight sciences teams worldwide — need solvers that encode their aerodynamic databases, control assumptions, and mission envelopes.
Hendoi builds custom flight-mechanics products: trim, static/dynamic stability, 6-DOF simulation, trajectory and missile flight paths, scoped for design offices and training academies.
Large companies get English docs, reproducible cases, and IP ownership for tools that sit beside CFD and mission analysis.
Industrial pain points we remove
Spreadsheet trim that does not scaleConfiguration trades stall when trim lives outside a real product.
Stability margins without a teachable toolAcademies and junior engineers need clear static/dynamic stability software.
Trajectory codes that cannot be ownedDefence and missile programmes need on-prem solvers with clear IP.
Weak link to aero databasesFlight mechanics must ingest your CFD/VLM or tunnel-derived tables cleanly.

Frequently asked questions
Can you use our existing aero tables?
Yes. Ingesting your databases is usually the first integration milestone.
Defence-sensitive on-prem delivery?
On-prem and controlled-update deployments are available.
UAV vs manned aircraft — different products?
Often shared core with envelope-specific modules — scoped per client.
Global OEM engagement?
Milestone plans with English validation packs for flight sciences teams.
