Launch-vehicle prep when ascent and stages must share regenerable cases
Custom launch-vehicle preprocessors — ascent aero, stage interfaces, and trajectory-coupled case setup for LV programmes.
Built for: launch providers, LV aero desks, and spaceflight research teams worldwide
Why OEMs commission custom solvers
Launch vehicles couple ascent aero, staging, and trajectory points. Prep that treats the LV like a static aircraft geometry misses the programme risk.
Hendoi builds custom launch-vehicle simulation preprocessors — ascent aero domains, stage interface setup, and trajectory-coupled case packs — for LV programmes.
Launch providers get English docs, acceptance cases, and IP ownership for prep that feeds aero, structural, and trajectory solvers.
Industrial pain points we remove
Static CAD prep for a flying trajectoryMach–altitude packs must be productised.
Stage interfaces brittleSeparation geometries need guided workflows.
Aero and loads out of syncTrajectory-coupled cases need one prep story.
Weak junior pathGuided packs reduce specialist bottlenecks.
