Aerodynamics and flight screening

Coefficient-based models over an explicitly limited flight regime.

density, speed, reference area, drag coefficient → drag force, power to overcome drag

density, speed, wing area, lift coefficient → lift, required speed or area

weight, wing area → wing loading, area demand

weight, wing area, density, specified maximum lift coefficient → conditional stall-speed estimate

lift-to-drag ratio, altitude, airspeed → glide distance, descent rate

diameter, RPM, density, calibrated coefficients → conditional thrust and shaft power

mass, rotor count and disk areas, density, efficiency → ideal induced power, adjusted hover estimate

usable energy, hover/cruise power, reserve → flight-time range

speed, characteristic length, fluid properties → Reynolds number, regime context

density, speed or pressure → dynamic pressure or indicated model speed
