This is a conceptual engineering sandbox exploring personal-scale WIG vehicles.
* Ducted thrust replaces sci-fi jet assumptions and is shown in the hundreds-of-newtons range.
* AFC is treated as boundary-layer / separation control, not as magic lift or reactionless propulsion.
* The vehicle is modeled as a low-altitude ground-effect craft, not a true stationary hover bike.

S_req = W / (0.5 · ρ · V² · C_L,eff · WIG)
D = D_par + D_ind, where D_par = 0.5 · ρ · V² · CdA
D_ind = W² / (0.5 · ρ · V² · π · AR · e), reduced by WIG
P_in ≈ (D · V) / η_p
