🛥️ Hovercraft Cushion: Skirt-Gap Leakage, Hover Height and Fan Power (2D side view)

Side view of an air-cushion vehicle floating on its skirt. Set the cushion pressure rating, mass, fan air speed, fan efficiency and gap discharge coefficient, and watch the craft lift off and settle where the fan flow equals the leakage under the skirt. Same lift and fan-power relations as the 3D page, with four in-page numerical checks.
