Complete feature list

Everything ZenRockets covers today — airframe design, custom motors, flight simulation, and flight analysis — linked to the guides covering each area.

Airframe design

Parametric nose cones, tubes, transitions, fins, rail buttons, and recovery parts — seven nose cone profiles
Freeform fin outline editor, linked dimensions, and radial patterns for clusters
Perspective, orthographic, and section cutaway views with on-canvas dimensions
Part presets and a material library covering common airframe stock
Live mass, CG, Barrowman center of pressure, and caliber stability
Import OpenRocket and RockSim designs and keep editing them like any other rocket

Motor design

Custom cases, five grain geometries, and converging–diverging nozzles
Custom propellants with pressure-dependent burn-rate regimes
Internal ballistics simulation — thrust, chamber pressure, Kn, and mass flow
Live motor cutaway schematic with cross-selection and CG marker
Cluster motor support with configurable ejection delays
RASP motor import that rebuilds an editable internal layout
Static-fire imports — overlay the measured curve, or fly with it

Flight simulation

Full-physics flight simulation driven by your actual design and thrust curves
Real launch sites, rail setup, and live weather forecasts from various weather models
Recovery deployment at apogee, altitude, or on ejection charges
Multi-stage flights with per-stage separation and ignition timing
Pre-flight validation with plain-language errors, warnings, and flight alerts
Adjustable solvers and tolerances, including stop-at-apogee runs

Flight analysis

Synchronized charts with an adaptive time axis, from apogee to landing velocity
Event timelines — liftoff, rail departure, burnout, apogee, deployments, landing
3D flight playback — scrub the timeline at quarter to 4× speed, with ground track
Compare up to five flights in charts and 3D, with tenth-of-a-second time alignment
Flight log import with Kalman-filter trajectory reconstruction and event detection
Resolved atmosphere profiles — wind, pressure, and temperature vs. altitude

Workflow

Undo-friendly editing with autosaved drafts and example rockets
Private by default, with public share links and cloning
Per-category metric and imperial units, stored in SI
Export printable parts as 3MF files for 3D printing
Dashboards for rockets, motors, flights, presets, and materials
