Interactive Flight Dynamics

First-principles physics running in the browser. Helicopters, tiltrotors, rotor wakes, and orbital mechanics.

2D · Longitudinal flight

Rotorcraft Fundamentals

Collective, cyclic, the power curve, autorotation, vortex ring state. Interactive teaching sim with full engineering derivations underneath.

Launch

3D · Six degrees of freedom

6-DOF rigid body with articulated-rotor flapping, tail rotor, fuselage drag, and live wake particles. Full flight deck with stability augmentation.

Launch

3D · Tiltrotor conversion

V-280 class tiltrotor. Dual proprotors, nacelle conversion corridor, tiered AFCS. Fly from helicopter through transition into airplane mode.

Launch

3D · Prescribed wake model

Prescribed-wake particle model. Tip vortex filaments, wake contraction, skew angle. Sweep across flight regimes and watch the geometry respond.

Launch

3D · Vehicle comparison

To-scale 3D models of Saturn V, Space Shuttle, SLS, Falcon 9, Starship, and more. Stage breakdowns, propulsion specs, structural dimensions.

Launch

3D · Orbital ascent

Gravity turn from ignition to orbit insertion. Live telemetry, staging events, vis-viva orbital elements. Eight launch vehicles.
