# Aerodynamic lift
# Scope: Lift at supplied constant coefficient; no stall or compressibility model.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

density = 1.225 kg/m^3
speed = 15 m/s
area = 0.5 m^2
coefficient = 0.8

lift := density*speed^2*area*coefficient/2 [N]

check lift target: lift >= 50 N

scenario alternative: density = 0.98 kg/m^3
