Physics-based jump simulation · snow & dirt
Kickers, step-downs, doubles — in snow or in dirt. Park Dynamics calculates approach speed, flight path and landing impact before the first shovel goes in.

Why Park Dynamics
Inrun velocity, flight trajectory and landing pressure — modelled with the same aerodynamic drag equations used in engineering, not rules of thumb.
Test a line on screen first. Spot an under-built landing or an off take-off angle before it costs you a rebuild — or a rider.
A phone check between laps. A full CAD workflow for a contest build. Snowpark or bikepark — same physics underneath, sized to the job.
Products
Better lines and safer landings — from a lift chair, a trailhead, or a workstation.

01 · Mobile
Quick checks, on the hill or at the trail
Set up a jump in a few taps and see take-off speed, flight path and landing point before you build.

02 · CAD Plugin
Full control for complex builds
Model multi-feature lines directly in Rhino3D, with friction and drag accounted for at every section.

03 · Consulting
Hands-on, when it matters
For contest builds and one-off lines: on-site input, custom models, and documentation your crew can build from.
State-of-the-art simulation
01
Delivers velocity at take-off.
02
Determines the landing point.
03
Impact pressure, and speed into the next section.

Runs through all three — not bolted on after.
Most tools stop at basic friction. Park Dynamics integrates aerodynamic drag and advanced physical models into every calculation — from inrun velocity to landing forces — so the numbers hold up closer to what actually happens out on the build.

Air resistance (blue) rises with speed and quickly overtakes rolling resistance. Ignore drag, and the forces on paper stop matching the forces on the ground.
