Cycle solvers
Gas-turbine and propulsion cycle decks for early trades.
Custom engineering software · Worldwide industrial delivery
Propulsion solvers from cycle decks to component fidelity
Custom gas-turbine cycle, compressor/turbine, propeller/fan, combustion, and nozzle solvers for aerospace/defence propulsion and OEM propulsion desks worldwide.
Built for: aero-engine and defence propulsion teams, eVTOL propeller programmes, and global turbomachinery / propulsion OEMs
Why OEMs commission custom solvers
Propulsion programmes need a ladder: cycle decks for trades, component solvers for compressors/turbines/fans, and selective CFD for hot sections and nozzles. Propulsion ecosystem players and OEMs worldwide struggle when each rung lives in a different rented tool.
Hendoi builds custom propulsion solver products — cycle analysis, component briefs, propeller/fan methods for eVTOL, combustion and nozzle options — with clear ownership and English validation packs.
We scope for large companies and propulsion desks that require on-prem delivery and integration with CFD/thermal stacks.
Industrial pain points we remove
Cycle tools disconnected from component truthTrades look fine until compressor maps and nozzle CFD disagree.
eVTOL propeller methods not productisedeVTOL teams need repeatable propeller/fan solvers.
Combustion/nozzle studies trapped in seatsSpecialty physics arrives late on vendor roadmaps.
Academy and OEM training gapsUniversities need teachable propulsion labs tied to industry methods.

Frequently asked questions
Cycle only, or full component CFD?
We phase. Many clients start with cycle + propeller/fan, then add component CFD selectively.
defence propulsion — on-prem?
Yes. Controlled deployments are standard.
Rocket nozzle work?
In scope when explicitly commissioned — we do not assume every client needs it.
Global OEM model?
Milestone scoping under NDA with English validation packs.
